Tutorials/Traps

This list doesn't cover mob grinders, the killing mechanism in mob farms.

Traps are a common mechanism in Survival Multiplayer (SMP) built by players to kill other players or mobs automatically. The following is a list of basic traps with a short tutorial that often assumes the reader has a working understanding of the basic concepts required to build the trap. Traps are considered a subset of mechanisms.

Greed
Traps utilizing a player's natural desire for riches to lead to his downfall.

Greedy man's grave
Requires: Diamond Armor (all), Diamond Block, Shovel, Pickaxe, Diamond Sword, Netherrack, Flint and Steel, Torches

Build a 3 block deep hole. Surround it with burning netherrack on all but one side. Put a block of diamond on top WHILE INSIDE. continue digging down for a long time. make a square room with torches. wait inside. When someone breaks the diamond, he will fall. If he dies when he hits the ground, the trap is a success. Collect the loot and leave. If not, the hole's too small. Kill the player, and claim the loot.

However, one may see the ruse and disarm the trap, possibly filling your trap with lava, water, gravel, or sand, covering the hole with obsidian, or returning with a friend, who may attack you when you get out.

This trap runs on people's natural greed, and the fact that sometimes, people don't think.

Simple Greed Trap
This trap is a very simple one. Just follow this tutorial and continue your way in trapping people! Click here

Inexpensive Greed Trap
Materials: Chest, TNT, Pressure Plate,Optional:Sand

Place a chest at the end of a long, 2 block tall hall made of stone or dirt. In front of it, place a block of TNT in a 1x1 hole, and a pressure plate covering the TNT.

Whoever walks over to the empty chest to loot it will ignite the TNT. You will need to restock it occasionally. For extra certainty of death, place a sand strip above the TNT's blast, with a layer of dirt or stone supporting it. Players will now suffocate too.

Curiosity and ignorance is the key
Sealed in trap. Make a chamber that has one entrance that is opened by a pressure plate outside (iron door)once the player is inside they can't get out. Then place another iron door a block to the right to the original door that contains a lever to open the original door but put it behind a new iron door (the one to the right of the original door, next build an item of your choice altar statue etc the somewhere add a lever that is connected to the newer door so it opens it, without patience the trapped person cant escape

Land Mine
Land mine: Place a TNT in the floor or ground, and a pressure plate on top.. Cover the trap with a natural looking block common to the environment around it, like use a stone pressure plate when in a cave. Although this has been removed in the recent updates here is what you can do. Dig a 1 by 1 hole two blocks down. Next put one peice of TNT at the bottom and cover it with a block that looks natural to the area. (a stone block in a cave ect) after that just put a presure plate on it and it's done. If a mob or player steps on it, It will go off.

Note: when using a wooden presure plate even thrown items will set it off and there is a delay between the priming of the TNT and the actual explosion.

Improved Landmine
First make a 5x5x4 hole. Next fill the sides and bottom with obsidian. Now you should have a 3x3x3 hole. Place two tnt on top of each other then another block and a stone pressure plate. Finally fill in the top section around the non tnt block with some cheap material.

Underwater Shelter
NOTE: used for multiplayer!

Build an underwater shelter. Put many valuble items in it. Dig a tunnel which leads to a shelter, the surface, or another safe zone. Cry out saying that you lost your way back, and that anyone can have it. Hide under it. When some one walks in, Ignite a block of TNT under the shelter and escape through the tunnel you dug earlier.

Burning Trap
Build a shelter that is created out of stone on the outside, wood on the inside. Make an iron door, with the switch next to a chimney. Make it homey, with excellent hard to get items. Put lots of ingots and diamonds in. Hide a block or multiple blocks of TNT on the roof, where you should be hiding. Put flint and steel in your inventory. When a player walks in, close the door. with a switch on the roof. Light the roof on fire, and then ignite the TNT. Run away. Depending on the size of the home, more than one TNT may be necessary for maximum damage.

Trapdoor Lava Pit Trap
This trap utilizes wandering mobs, trap doors, lava, and pressure plates. To see how it's made, view the diagram on the left, and to see it in game, view the image beneath it.

Mined Ore Trap
(Note: this trap is best used in a cave or an underground home) Very simple. Use the double door bug so one of the iron doors stays open and then put a pressure plate inside a room. Then mine a block out of the wall and place lava 2 blocks back and seal it up with some ore, so when people mine the ore, the lava comes out and they can't escape because when they try to exit the iron door closes. Here is an overhead view: X= wall D= door P= Pressure Plate O= Ore L=Lava XXX XLX XXXXXOXXXXX X        X                    X         X                    X    P    X                    XXXXXDxXxXX

A very similar trap to this one is to fill the person's house with block 97 (which spawns silverfish when mined). Mining it also has the added bonus of activating other silverfish blocks in the immediate area. When they mine the block, they will be attacked, if not killed. Watch this video as an example.

Door Pitfall
This trap is very simple. In front of the door you want to dig down a 1 by 1 hole as far down as you want. Make sure your pit is as close to the door as possible, what I'm saying is that you dig the pit from the same side of the door as the side that you placed the door from. Once your pit is done, return to the surface. Place a TNT block 2 blocks down in the pit. Place a sand or gravel block on top. Then put a STONE (this way it can only be triggered by players and mobs) pressure plate on the sand/gravel. When a player or mob steps on the pressure plate the delay between the pressure and the door opening will be just long enough for the TNT to activate, causing the player or mob to fall to their deaths. Notes: The delay will only help if there is NO gap whatsoever in between the pressure plate and the door. Optional: Place lava at the bottom of the pit so players aren't motivated to come back for their drops (make sure lava is placed more than one block from the bottom so it isn't smothered by the sand/gravel).

Door Trap
This is a very simple trap that is made by putting a pressure plate in the middle of 4 open doors so that the victim is trapped inside when they enter, you may also decide to put a block 2 blocks higher than the pressure plate to stop the victim jumping out. This is a very quick and easy to set up trap, making it ideal if you are new to minecraft or simply in a hurry. It is also recommended that the pressure plate is made of stone so that a player can not activate the trap without standing on it, this can be achieved by throwing a block onto a wooden pressure plate. A simple way to make it into a drowning trap is to add a block of water in the block above the pressure plate. When combined with a block on top, the player/mob will drown and not be able to escape. Another way to make this trap more deadly is to place a block of TNT right under the block with the pressure plate on it. Since TNT explodes relatively fast, even if the person manages to get out of the trap quickly, the TNT will probably explode before they have moved a safe distance away. Another fairly simple way is to replace the doors with iron doors and make the top stone and the pressure plate stone and put lava in the middle burning player/mobs making easy to collect there items.

TNT Door Trap
This is a very simple trap. Start out by building a simple, one story shelter (but don't put in a door yet). Then, go inside the shelter and replace the floor with a two-block deep hole. Cover the bottom of the hole with TNT, then cover the TNT with flooring material. Place valuables inside as needed. Now, exit the shelter and place a pressure plate one block inside the doorway. This plate should be above a block which is above a block of TNT. Place an iron door in the doorway and one pressure plate outside the door. A would-be griefer will step on the outer pressure plate, causing the door to open. When they enter, they will step on the inner pressure plate, thinking nothing of it because it looks like the pressure plate reopens the iron door when they exit. In reality, it's simultaneously triggering the hidden TNT. They'll be blown up while trying to steal your stuff.

Trap Door Trap
This is one of the simplest traps to make, and does not require many materials. First, you have to find a place where this trap can be easily concealed, such as a dark doorway or another clever hiding spot. Next, you simply dig a hole about 7 blocks deep, and 1 block wide. Use a bucket to fill the hole 6 or 7 blocks deep with lava. Then, put a wooden trap door on top of it and a pressure plate in front. Players will walk on top of the plate and through the door and fall into the lava. NOTE: This is not a very high quality trap.

Fake Entrance Trap
\baaaaaaaaaaaaaaaaaaaaa

Fake underwater mine trap
This one is fairly simple (but time consuming). Dig a 2 x 2 hole realy deep. Put signs in the second block after the surface and make a water pool, so there`s nothing but air below. So, put a sign saying something like: "Diamonds here!" or "Mine". The unfornate player will jump in it and die from fall damage. Unavoidable (unless you have a mod).

Semi-Advanced Traps
Many traps require some redstone wiring, but these take a significant amount and require a basic understanding of redstone circuitry. Explosive traps, those that use TNT, may destroy sections of redstone wire if the explosion occurs too close.

Arrow Dispenser


This trap is created by attaching a dispenser filled with arrows to a clock generator. When the clock triggers the dispenser, an arrow will fire. The rate of fire is limited by the clock; slower clocks means fewer arrows shot over a given time period. With a rapid pulser, the dispenser will fire roughly 5 APS (arrows per second).



Since dispensers don't 'burn out' like torches, it is possible to greatly increase the rate of fire of the dispenser by attaching it to a rapid pulsar. To wire this, connect the rapid pulsar to the dispenser, give the dispenser another power source (such as an adjacent redstone torch). By connecting the rapid puslar to a stable input (such as a torch controlled by a lever seen to the right), the dispenser can be controlled by turning off the torches in the pulser.

The trap can be automated by attaching a pressure plate to the control torch. When the pressure plate is active, the pulsar is allowed to fire, presumably at the mob or player on the pressure plate.

One way to improve this trap is to place it at the end of a long thin corridor with an iron door entrance. The iron door is opened only from the outside via pressure plate. Have the pressure plate wired to an RS NOR latch so that once activated it will remain active, but can be deactivated by a hidden button.

Rapid Pulsar Arrow Dispenser


While a standard pulsar will flicker on and off quickly allowing the dispenser to fire rapidly without the manual addition and removal of power, it is often too fast and will cause delays in firing due to the dispenser not being able to keep up. The design on the above diagram compensates for this by slightly slowing the interval between pulses.

It is important to note that in order for the trap to work, the input (I) to the rapid pulsar must be turned ON when the operator does not want the dispenser to be firing. When the power is turned off the circuit will begin pulsing at a steady rapid rate. This allows the arrows to be fired at the quickest rate without delays between shots. A constant power source must also be applied to the dispenser in such a way that it will not conflict with the input of the pulsar to the dispenser. A single redstone torch one block above the dispenser will accomplish this.

This trap works best as a player controlled mob-counter-measure through the use of a switch, as a pressure plate would only send power through the pulsar when a mob is standing on the plate (although a NOT Gate wired to the input before the pulsar could be used to compensate for this).

Undetectable Trap
A trap that is based on the fact that you can pick up dropped items through the corner of 2 blocks, which makes the trap undetectable without xray. The dropped item sits on a wooden pressure plate, which is connected to an inverter that holds open a line of sticky pistons that hold the floor. A tutorial for this kind of trap can be found here: http://www.youtube.com/watch?v=Y96hqyYD83k

Lava And Collection Trap
You need one sign, 1 bucket of lava and 2 buckets of water.

Make a trench 2 wide and put the water flowing down it. Then put the sign at the end on a wall. Put the lava over the sign. Make a glass hut at the end of the trench an wait for the monsters to start rolling in.

Crushing Trap
This trap uses pistons to crush skeletons, zombies or players to death. For every square meter you'll need a sticky piston, two cobblestone, and one piece of redstone dust. A lever is also needed to trigger the trap, plus some extra redstone dust.

Dig the room so the ceiling is 6 blocks high. Place sticky pistons all around so they are facing down at you on the 4th block up. There should be enough space above the piston to walk on it, and enough room on the floor to jump. Replace the ceiling using cobble just beneath all of the sticky pistons. The room should now appear to be 2 blocks high, with 2 empty blocks above the pistons (unseen). Using a maintenance shaft, get in the area just above the pistons. Place cobble to cover all the pistons. Cover the top cobble layer with redstone dust. Then, make a trail with redstone dust to a lever. From here you can trigger the ceiling.

Upon activating the lever, the pistons will push the blocks down and start damaging tall mobs and players. This design can be converted to use pressure plates on the ground to activate the trap rather than a lever. To be effective against spiders and short mobs, lower the entire trap by 1 block, or cover the floor with sticky pistons facing upwards and wire them as well.

Corridor trap
The following Trap uses pistons to suffocate and trap the player. once the player dies, they cannot get their items back, and if the player does set the trap off, but doesn't get killed by it, they still can't make it past.

An advantage of this trap is that it can be reset with the press of a button, or completely disabled, if needs be. It is not very obvious - and can simply be disguised as an iron door.

Suffocating Piston Trap
The following piston trap suffocates the player slowly by filling the room with sand and continuing to fill it until they die or there is no sand left. The following video shows the trap "in motion" and how it's made:

Proximity Bomb
A proximity bomb is a player detector paired with an output of TNT. It destroys itself and blows up it's surrounds when the player gets close, and it should often be undetected.

This design, the smallest by far, involves the use of cave spiders as they are the only mob that can fit in a 1x1x1 area.

Vechs, the creator of the Super Hostile adventure map series, came up with multiple designs for a proximity bomb, the first involving creepers, taking advantage of light levels and gravity. His second, shown here, takes advantage of the ability of blazes to spawn in higher light levels than average hostile mobs.

Mined Block Trap
This type of trap uses a player mining a block as input when setting off the trap. A "NOT" gate is used so that when the player destroys a block with a redstone torch on it, the second phase of redstone is turned on, causing the TNT to be set off.

An advantage of this style of trigger is that the signal is created without the target activating a pressure plate or pulling a lever (in the case of a player). It is also easy to build, since you can wire multiple blocks all over the map. Based on the location, different blocks should be used. Caves may use ore, deserts may use exposed ore (as though sand had fallen to expose it), and player built cities may use rare blocks such as diamond or gold.

Instead of using a NOT gate one can simply use a piston to push a TNT block into an active circuit. The advantage of this method is, that the trapped block does not need to be wired itself:

Sticky Piston Trap
This trap is similar to the door trap, except less visible. The design involves 4 sticky pistons, 1 pressure plate, and 4 blocks to hide the sticky pistons. Dig 1 block down, and place the pressure plate in it. Dig two blocks down the blocks adjacent to the pressure plate. At the bottom of each 2 block deep pit, place a piston. Place 4 blocks that can be pushed by pistons above the pistons. It is advised to use blocks fitting the environment for low visibility. It is possible to create a chain of piston traps side-by-side and make a barrier.

Note: Do NOT use sand or gravel as your blocks effected by pistons.

Roof TNT Trap
A 'Roof TNT Trap' can be made by putting a pressure plate next to a door then wiring that pressure plate to activate TNT hidden in the ceiling. This works best in a small area such as a mine. To limit the space the target can run, use an iron door and only place the pressure plate on the outside. To further limit the space the target can run, have the pressure plate also wired to an inverted piston that drop gravels, blocking the remainder of the tunnel.

Disguised TNT Trap
A disguised TNT trap uses the activation of TNT to remove the support for a block of gravel. The TNT cooks while the target is falling down a narrow hole. This can be expanded to cover a larger area by using signs or torches to support additional blocks. Wiring can be done most effectively by placing gravel on TNT with a pressure plate above the gravel. Also, if there are two blocks of lava under the TNT, the victim will burn to death before blowing up.

Pitfall
Beware: the following pitfall traps don't necessarily kill the target by falling damage. Some players prefer to use fire, lava, or cactus to deal damage and use the pit as an area the target can't escape before fatal damage has been dealt.

TNT-based pitfall trap
Create a deep 3x3 pit (deep enough so mobs will die upon hitting the bottom). Two blocks down from the surface, place a layer of stone or cobblestone. On top of that, do the same, but make sure the center block is TNT. Finally, place a layer of any block type on top (except TNT, of course). An advantage to stone/cobblestone is that it takes less blocks, while an advantage to dirt is that upon the TNT's explosion, it creates a small ledge around the pit you can stand on to help rebuilding. After your top layer is done, put a pressure plate on the block above the TNT. When a mob - or player - walks on the plate, the TNT will trigger, damaging them and making them fall to their death in the pit below. To collect the items, create a maintenance hallway to the bottom of the pit.

TNT-based pitfall trap (Easy)
Dig 3 blocks down but stay on the surface. Put a block of sand on the bottom of the hole, and a block of TNT on top of the sand. Place a pressure plate on top of the sand and when a mob steps on it, it will trigger the TNT and the mob will take damage and fall into the pit created by the explosion.

WARNING! ''Mobs will NOT BE DEAD upon finding (unless they burn in sunlight). Shoot them with arrow(s) until they die. Happy hunting!''

Cactus-based pitfall trap
One way to dispatch a target is by filling the bottom of the shaft with cactus. Since cactus can't be placed adjacent to blocks, a checkerboard pattern must be used. Players and most mobs will fall between the cactus and be unable to escape. Spiders won't be able to fall between the cactus and, depending on the design of the shaft, may be able to escape before taking fatal damage.

Shallow pitfall
Dig a pit 1-block deep hole at least 5x5 blocks. Place fences on the inside edge. Since fences count as one and one half blocks in height, mobs can walk in but can not jump out. Alternatively, line the outside with half-slabs. Zombies and Skeletons will take damage from sunlight during the day if the pit is uncovered, making this an effective way to sort out creepers. This design does not capture spiders.

Water-current based pitfall trap
To effectively improve the size of your pit without digging a larger area, dig a shallow ring around the top layer of your pit. Fill this area with water so that mobs will be dragged to the center. If necessary, water can be stopped by placing signs or Stone Pressure Plate.

Wired pitfalls
Pistons and other redstone blocks are sometimes used to push the target into a nearby pit or, you can have a lever beside a door, and wire the lever up to a piston that uncovers a hole in the floor so that the target falls into a pit of lava.

Snowball-based pitfall trap
Load the dispenser with snowballs (or eggs if you find them easier to get and arrows if you wish), and aim the dispenser at a connected pressure plate next to the pit. When the target walks across the plate, the dispenser shoots a snowball to knock the target into the pit, where they can be dealt with however you like.

The Obscured Pit
The mechanism is a pressure plate attached to 5 pistons: 4 pistons that retract, and one that extends. Build this in a flat sandy area. Wire the pressure plate to an inverter then to 4 sticky pistons 1 layer underground. When the plate activates, the pistons should open a 2x2 hole. Replace the sand on top of the extended pistons on the ground. Then, under the sand manipulated by the pistons, make a hole as deep as you want. It can have water supported by signs, so as not to kill your victim, or they can plummet to certain doom. Then, add a normal piston wired into the plate so as to push the victim into the opened shaft. Then, you can replace the top layer of sand.

Pitfalls using pistons
Another kind of pit is the piston pit. In this pit trap a sand structure is build on an activated piston. The structure itself uses torches to keep the sand at the top. The structure is build like an upside down pyramid so that one sand block is holding the others. When the piston is toggled, the main sand block above the piston will fall triggering a cascade in the rest.

This trap is easy to reset if enough sand is available, you just have to put new sand on top of the piston and build a new sandfloor. If sand is scarce, you may want to build a maintenance shaft to the bottom of the pit to retrieve the sand.

Repeatedly triggering a trap of this type without collecting the sand from the pit will eventually fill the entire pit with sand. To counter this, you can set up a floor of torches, redstone torches, redstone repeaters and/or tall grass. As the sand blocks fall on these objects, they will break and produce lootable sand blocks. These could possibly be collected (along with the victim's items) by the owner of the trap for future use, although they have to be picked up very soon after the trap has been triggered, as they will despawn in a couple of minutes like any other lootable items. A more elaborate system could even have the sand and items redirected to a water stream which leads them to a collection point.

Non-Destructive TNT Death Hole
This trap uses TNT, but does not destroy the pit or any blocks other than the sand/gravel disguising the pit. Dig a deep 6x6 hole. put obsidian in the bottom and sides of the hole,turning your 6x6 shaft into an obsidian tube with a 2x2 hole. Put a redstone wire on one of the obsidian blocks at the top layer of the pipe. Put TNT next to the wire, above the hole at the top of the pipe, and disguise the pit with dirt etc., but put sand/gravel above the tnt. It should look something like this:

R   R  O T TO  O    O  O    O  O    O  O    O  O    O  O    O  O O OO

P= Pressure Plate R= redstone wire T= TNT O= obsidian

Wire the TNT to a trigger, ensuring that players will walk onto/near the sand/gravel and activate the TNT. The TNT drops them into the hole, and blows up without destroying any blocks other than the sand that the player stood on. All you need to do is replace the TNT, sand and the trigger for another use. This could perhaps be wired to some pistons that automatically reload the TNT and sand.

Water and lava-based traps
Fluids are often used in traps. Water is generally used to slow players and to drag mobs, but can also be used to drown them. Lava works entirely different by igniting the target. It is a very effective way of killing the target, but also destroys drops if they come in contact.

Water
Traps using water.

Mobavators To Automatic drowning trap/ any other trap
Mobavators can be used to move mobs from low in the Minecraft soil to up in a mob grinder, mobavators are useful when connected to drowning traps so they can haul a lot of mobs up into the trap. Usually mobavators are expensive from low in the ground but for players with a lot of resources they can be very useful. the usually work like this:


 * X = sign Y = Glass/Any other solid block for lower in the ground O= water
 * YXXY
 * YOOY
 * YXXY
 * YOOY
 * YXXY

An alternate design:
 * YXOY
 * YOXY
 * YXOY
 * YOXY
 * YXOY

Drowning room
Make a small room preferably 5x5x2. Place a chest in the centre of the back wall. Then put 2 blocks of sand above the chest with water behind it. As soon as they break the sand to enter the chest the water will pour out. If you want, you could have an airlock instead of the one-way door. Have torches supporting sand in the hallway to the trap as soon as the water comes out it will flood the hallway and burn out the torches, causing the sand to fall trapping the player even more.

Automatic drowning trap w/ trapdoors
This trap is made by digging a 2x2x3 hole in the ground, filling the middle of the hole in water, and putting trapdoors at the top. Then pressure plates are placed a block away from the trap in a square pattern to open the trap doors, and between the pressure plates and the trap redstone wire is placed to open all the doors at once. When a mob walks over the pressure plates he can fall down the water, and the trapdoors will shut down, leaving him to drown. At the lowest level of the trap you can make a 1x1 tunnel of water to retrieve the loot. Generally these are the most efficient types of traps because there is no lava involved to burn any loot.

Retrieval Traps
Create a water current that drags the mobs down under a solid block. The current will hold the mobs under until they drown. The loot from the mobs will sink, which can be collected below.

Water Whirlpool Trap (Water Tower)(Atlantis Trap)


This trap is used as a water barrier to keep the mob from swimming into an area. This requires that the floor of the body of water be easily accessible. However, the trap is extremely effective and rather large, sucking in a 6x6 area of water.

Dive down to the bottom of the pool of water. Build up a hollow tower of out of a weak material, ideally sand. The basic template is a square hole, at least 2x2. The air gap will be this size.
 * x = sand O = empty
 * O X X O
 * X O O X
 * X O O X
 * O X X O


 * Make the top flush with the surface, then empty the tower of water using a bucket. Set four TNT blocks as low as possible,then light the TNT and run.
 * T = TNT X = sand O = empty waterTower3.png
 * O X X O
 * X T T X
 * X T T X
 * O X X O

The TNT does not have to be on the bottom. The result will be a 2x2 tower of air going from the surface to the bottom with waterfalls on all sides.

Dark Room and Drowning Room Trap
This trap consists of : large dark room (any size from 8x8x8 upwards/outwards)

drowning room consisting of many signs, water, a block (solid and non transparent) and trapdoors

collection room (optional) under drowning room image will represent how drops get carried there. To create drowning room :

B F F F F F W <-- only 1 'W' on 1 side

'B' any solid and non transparent block 'W' water source 't' trapdoor 's' sign 'f' flowing water

Door Jail drowning trap
for this you will need:1 water bucket, 1 stone/wood plate, 4 iron/wood door, and 2 block

place the plate (I would use a stone plate I will tell you why later) place the door (I use iron) make shure the rigges are FACING the plate. Place the 1st block then the 2nd over that block, destroy the 1ST one and place the middle of all it. Why I use a iron door and stone plate is the stone plate will automatically open the doors after drowning. And the iron doors will trap playyers too. this works with lava too.

Lava
Traps using lava.

Lava ladder trap
This is designed for use on a SMP server. Make a 'dummy house' (A house that is not really a house, it is only to lure people). Put some ladders that go to the second floor of this house and at the top of the ladder, put some lava. The lava will not go down the ladders. Now when people go up the ladder they may climb into the lava, because some players don't look up when climbing. And usually falling off the ladder so their items won't burn. This trap will also work downwards but it is not as effective.

Emergency Lock Down Trap
An emergency lock down trap ensures players can't bypass a redstone lock system by breaking the door. It uses an iron door as support for the initial sand block. A diagram for the completed section of the corridor can be found to the right.

Place the iron door in the middle of a tunnel with adequate space. Connect the iron door a redstone lock system. Dig above the door until the area above the hall is a hollow 5x3 area. Place sand on top of the door, then place torches on the side of the sand. Repeat until the sand touches the wall. Place lava in the empty space above the sand. The only way to get through would be to unlock the redstone lock system. If someone destroyed the door, the sand would be unsupported allowing the lava to fall on them. To stop players from simply mining around the device, place lava behind the walls.

Since lava spreads slowly, it may be possible for the thief to destroy the door then quickly run to safety on the far side. To counteract this, include an airlock style sand pillar to block the path. If the thief tries to break it down, the lava will have enough time to spread and ignite him.

Griefer Lava Pit Trap
It's nearly impossible to find a SMP server without griefers who try to steal your valuable collectables. A very simple trap using paintings can be made. As most players know, hanging a painting in front of a wall can cover up corridors, but the painting can still be walked through. Most griefers know this too and if they spot a large painting, they usually try to walk through it to see if they can find a secret room. Knowing this, you can build a wall of any size, implement the standard painting-coverup, but instead of making a secret room, make a pit about 3-4 blocks deep and put some lava on the bottom. It's nearly impossible to do this without killing yourself, so don't take anything except a lava bucket. When griefers try to enter your 'secret room', they'll fall in a lava pit instead!

Glass Pane Trap
With the glass panes added in Beta 1.8 and the ability to fall through them when joined in a 2x2 fashion, this can be made into a good trap. Lava can work in this fashion to have drops fall into the chamber below the lava.

Piston-Lava Trap
This trap is based on the fact that, when un-supported, sand and gravel fall. This trap will also need a basic understanding of redstone (how to make a current move vertically and how to make an inverter). The basic layout for this trap is a sticky piston, holding out some TNT (to remove the sand once they both drop), of which below it is a pit of lava and a block of sand or gravel with a stone pressure plate on top of it.

Firstly, you want to dig 2 blocks down in three spots, making a rectangle.At the end of the blocks, you want to place a sticky piston, facing the other end. then you want to dig down two blocks next to the back of the piston and place a redstone torch. once the piston has shot out, place some TNT on the sticky piston head on top of the TNT place some sand and a pressure plate on top of that. Next you want to lead some redstone into an inverter, and then lead the output from that inverter into the redstone torch you placed at the beginning.After this, of course you will need to dig out below the TNT and make a lava pit, this should be quite far down, because, if someone somehow doesn't die because of the lava, the TNT will blow up next to them. When you step on this trap, the sand will fall into a pit of lava, taking you with it. to reset this trap you simply need to place the TNT, the sand and the pressure plate back to where they started.

Proximity Detector
There is a way to detect if someone is within a certain proximity (17-20 blocks) in minecraft. This is extremely useful for traps. Here is a video tutorial on how to do that:

Mob-spawning-based: This player sensor is the smallest stable silent player detector that isn't glitch based.

This video shows another way to create a stable player detector, this time based on redstone.

Particle-based:

Netherrack and cacti wall


In the ground, alternate netherrack and sand. Ignite the netherrack and plant cactus on the sand. This very simple trap acts as a wall against hostile mobs. Passive mobs only spawn in light (They are NOT attracted to light in any way and will often wander off in the dark) and will sometimes wander into the fire. Generally the mob will then ricochet off the cactus preventing any drops from being destroyed by the fire.

Soul Sand Live Capture
Soul sand slightly sinks the player. Using this unique property, it is possible to capture a tall mob or player. The corridor to the right will trap a player that moves onto the soul sand. The top half shows the floor setup and the bottom half shows the ceiling. Note the open block above the soul sand. Players are caught until they place a block above them or destroy a block around them. Generally the rest of the trap will have triggered by the time they react. Pressure plates can be placed on soul sand to help hide them and to provide a redstone signal. '''NOTE:For a kill during this process, place lava by the soul sand. May not always work if placed wrong.'''

Repeater-based One Way Hallway
If a repeater is in a 2 block high space, like a tunnel, you will crouch automatically as you walk over it. However, you will not crouch if the repeater is blocking the entrance of a tunnel.

Make a 1x2 tunnel. On the floor of the entrance place a repeater. To punish players for destroying the repeater, have it as part of an inverter connected to TNT, such that when the repeater is destroyed, it activates nearby TNT.

Minecart Fall Damage Trap
There is a way to 'store' fall damage in a minecart and later have someone take that damage even though they don't actually fall a distance that would make them take damage. Here is a video explaining how to set the trap up and showing it in use:

Noise machine
In certain cases it may be helpful to mask the sound of TNT or hostile mobs by creating a noisy machine. The function of the machine itself isn't important. Pistons create a fair amount of noise that doesn't travel far. Doors can be quickly toggled making a lot of noise.

One Way Door
A one way door is made by placing a pressure plate in front of a iron door to a closed room with no way to open the door from the inside. The pressure plate briefly activates the door, but will close it immediately after. This technique is useful for capturing mobs for resource harvesting. This can be expanded to create rooms or large pens for trapping monsters.

arrow fall trap
have an underground tunnel built with another tunnel coming straight down midway to intersect it

t    t     t     t  ttttttttttttt

at the top of the intersecting tunnel build a room

rrrrrrrr rrrrrrrr rrrrrrrr t   t    t    t  tttttttttttt

at the top of this just in-between the tunnel and room build a dirt patch to block it up then place one tnt block over the center piece of dirt

rrrrrrrrrr r       r   r   x    r   rrdddddrrr ttttttt ttttttt ttttttt ttttttt ttttttt tttttttttttt tttttttttttt tttttttttttt

next fire a ton of arrows at the dirt and tnt and build a staircase from the room to the tunnel hide the stairwell with plain stone but dig one space below the hidden doorwayand one behind that into the starwell. place a pressure plate next to the hidden door and run redstone from it to the tnt in the top room. now when a person sets off this plate it causes the tnt to explode with the dirt, (not blasting the arrows away becauuse of a patch) with the dirt no longer there to hold the arrows they will free-fall down at the intruder at the same power as a fully charged arrow. p.s. it helps to have the intersecting tunnel wider then the hole itself as to reduce chance of arrows sticking into walls.

Disarming Traps
When faced with a trap, the safest course of action is often to disarm the trigger by destroying the trap's components. Note that disarming a trap could be griefing. But if they are trying to kill you, you should defend yourself


 * Destroy pressure plates. Pressure plates send the same message whether they are inactive or destroyed. Destroying a pressure plate will seldom trigger a trap.


 * Be wary of active redstone. Inactive redstone is safe, but destroying active redstone dust can trigger traps, as it is usually connected to an inverter. Remember that redstone can be removed with water.

X = torch Y = redstone wire B= Any block Front view: XYX BBB Top view: Layer 1: B B  BBB Layer 2: X X  YYY And then destroy the center redstone: X X  Y Y It will keep the positive input for both ends, but cutting the two ends off, keeping the current on forever.
 * You can dispatch active redstone wires with the use of two redstone torches:


 * Never alter a clock generator! It may be connected to another one by a logic gate that checks if they tick together. This way the breaking or altering one may trigger a massive TNT charge or other anti-defuse mechanisms.


 * Consider the fact that the creator may be nearby. Oftentimes, the builder of a trap will be near the trap, waiting to collect his victim's possessions.  If you encounter a trap, be ready for a fight.


 * Remove the trap's dangerous components. If you can reach the dangerous bits of a trap, destroy them.  Take the arrows out of a dispenser, and pocket the dispenser while you're at it.  Take any cacti you see as well. TNT should not be a problem, since the 1.7 update TNT blocks can be broken and collected


 * Some texture packs may make traps easier to disarm than others. While you might accidentally walk across a pressure plate and activate a trap while using one texture pack, you may spot it instantly with a different one. It may also help to use an x-ray texture pack to spot parts of the trap that you may not have been able to see before, which should help you better understand how the trap works.


 * If all else fails, try to safely trigger the trap. Either step on the trigger and run, or use redstone to trigger it from a distance.  It is best to have a good understanding of the nature of the trap before attempting to trigger it, as one can easily underestimate its size.


 * You can also trigger the trap, log off, and log back on after a moment has passed. However this may be dangerous as nearby TNT could have been detonated (even revealing a pit), so when you log back on, you may take damage from the hole the TNT made, possibly resulting in death.


 * To fool the person who laid the trap in SMP, try burning out the torches, but make sure you know the wiring. Therefore, if you want revenge unto the person who tricked you into the trap, you can leave a trace and then the person will want to fix it. Kill him once that happens. Keep in mind, tinkering with circuits might not only trigger the trap you know; it can catch you in another.

Creeper/Zombie Catcher

This is a fairly easy trap that recuires the following -4 pistons -1 Redstone Dust -1 Pressure Plate (Preferably Stone) -5 Cobble Stone

Step 1- dig a 2 block deep trench shaped like a + symbol step 2- Place the redstone dust in the center of the trench Step 3- place the 4 pistons in the edges around the redstone Step 4- Place 1 Cobble Stone on top of each piston Step 5- in the center (Above the redstone) Place a dirt block Step 6- Place a Pressure Plate on top of the dirt Step 7- Place the last cobble stone block 2 blocks above the pressure plate (This block keeps the creeper/Zobmie from jumping out and protects them from sulight) Final Step- Try to lure a monster into stepping on the plate. The pistons will then push up the cobble stone which will successfully trap the monster. The will be unable to jump or walk out. You may then procedd to kill them, observe them or keep them as a pet.
