Talk: Monster Spawner

Revision as of 00:53, 24 January 2011

Lava is a fluid block. Sources of flowing lava can be found in subterranean caves, and occasionally at the surface. Lava springs are usually found deep underground, however they can rarely be found above ground. Occasionally you can find lava lakes above ground. Lava Source blocks are also extremely common in large lakes in the Nether. Contact with lava is dangerous and deals damage to players and mobs.

Behavior

Classic

In Classic, lava spreads by duplicating itself to open horizontal and downwards squares like Water. Lava is slower, though, and can be easily outrun. A quick player can block the flow of lava by building a dam. However, if the lava wave is large, a player may not be able to build fast enough. Also like water, lava slows down the player moving through it but it does so to a greater extent. Lava is also more opaque than water and is harder to see through while you are submerged. You cannot see through lava from outside it. At the bottom of the map, lava can be found directly above bedrock in a different form, as it will trap the player and prevent the player from leaving unless water is let in and collides with it, or the player hits R and respawns.

Survival

Since Infdev, lava flows more realistically across surfaces but not as much as water does. Lava will flow for a total distance of 3 blocks away from the source block (further in The Nether). Just like water, lava will flow in a single line towards the nearest terrain depression within four blocks. Items thrown into lava flows will disintegrate. Though most objects burn instantaneously, obsidian takes a few seconds longer.

The amount of damage has been reduced to a half of a heart being removed for every second the player is in lava, in addition to the damage from fire. It will however deal the full 5 hearts of damage if a lava block enters a square the player is in where there wasn't one before, such as placing one where the player is standing or from flowing lava entering the player's block. Lava is no longer present at the bottom of maps in this mode. Lava can melt ice and snow, much like torches can, but melt a larger area. Lava is luminous and a large lava flow is visible in the dark from quite a distance.

If a horizontal lava flow collides with water, Cobblestone is created, but if a vertical lava flow collides with water, the water is removed. Since Alpha v.1.0.6_03, Obsidian is created from water colliding with a lava spring. This "technique" can be used to manipulate water and lava or to harvest cobblestone and obsidian.

In Beta, lava is less reactive with horizontal water flows. It also has a chance of forming redstone ore when water runs on top of it ^{[citation needed]}. Lava flows or pools without a source will degrade to dirt after a given time period.

Since the 0.0.19a client update on June 20, 2009, Lava's texture became animated.

As of Seecret Friday Update 9, buckets of lava can be used to fuel a Furnace for 100 smelt; however, the bucket itself will be consumed in the process. Before the December 3rd update, right-clicking a furnace/workbench/chest while holding a lava bucket would leave you with a lava spring on top of the said item, but now it just opens the inventory as it would have if you were carrying, say, a stack of wood^[1].

Redstone

Using a redstone wire, a one-block lava flow can be redirected by supplying power to the spring block, which will cause it to reset the flow towards the now-nearest terrain depression. This is further elaborated in this thread. It cannot, however, be reversed.

This re-calculation is made because redstone wire when toggled changes the block from redstone(on), to redstone(off). whenever a block updates on any side of lava, the lava re-calculates where to flow, but does not cut off its current direction of flow.

Features

Spring

You can collect and place Lava blocks using a Bucket. Placing the Lava block will create a Lava spring. Sometimes lava flows will linger, this is apparently intentional, and it will stop lingering given enough time. As with Water, you can only harvest these springs, not the flowing lava coming from them. Unlike water springs which can be infinitely duplicated, lava springs are finite.

Ember

An ember is an untouchable fireball that occasionally jumps out of Lava.

Lakes

Since December 3^rd, sometimes lava lakes appear above ground. This, however, is uncommon.

Furnaces

A bucket of lava can be used to fuel a furnace for long enough to smelt 100 blocks. This consumes the bucket as well as the lava.

Trivia

Lava is only called lava once it reaches the surface, and is called magma when underground. As such, most of the 'lava' in Minecraft is actually magma.
When lava is present in diagonally adjacent block to the player, the player will occasionally catch fire while running into that corner. (south-west rule)
Lava is a good tool for creating incinerators. It can destroy junk blocks and tools that are not needed.
It is impossible to create an "infinite pool" of Lava.
When you stay in Lava for about 1-2 seconds, your character makes noises which appear to go along to "When the Saints Go Marching In."

-Anyone been able to test the spawn radius of a Mob Spawner? [[Special:Contributions/173.20.67.107|173.20.67.107]] 14:18, 31 July 2010 (UTC)
-:it is a fair few blocks. I'd say, about 7 block radius?
-::I've seen instances where I'd dig around the dungeon and create hallways. Sometimes the mobs will spawn in the hallway if no lit properly, proving that a wall won't stop the spawning. Anyone confirm? -- [[user:MrMatthew|MrMatthew]] 10/05/10 14:52 PST
-:::I cannot confirm this. Are you sure this isn't the effect of monsters spawning in darkness and is completely unrelated to the mob spawner? [[User:Noroom|Noroom]] 01:42, 7 October 2010 (UTC)
-::::It's completely possible, but I haven't seen too many random mobs spawn while underground. I dug the hallway around it, walked out for a bit, and turned around to find a zombie wandering around. Coincidence that it was so close to the spawner? Maybe. Something to test (if possible) though. [[User:MrMatthew|MrMatthew]] 15:47, 7 October 2010 (UTC)
+== Behavior ==
-I can't confirm it but I'm pretty sure they do spawn outside the dungeon. I dug a pit underneath it, completely closed off the dungeon after placing torches throughout the dungeon and removed all torches in the pit. It didn't take long for two zombies to appear there. Of course the part they spawned in wasn't lit up so it could have been a random spawn but I've never known to spawns to happen with rapid succession and it happened right after I removed the torches. The zombies spawned 5 squares deeper than the spawner and 4 squares off from the side.

-:I have done extensive tests with both a zombie spawner and a spider spawner in Beta SSP and with the wall around the spawner at a four block radius, no zombie or spider was ever generated outside of the wall within approximately 16 hours of testing and so I have updated this wiki accordingly.  --[[User:KADC|KADC]] 10:36, 15 January 2011 (UTC)

-Has anyone tested whether mobs will spawn during the day? Or underwater? I can't seem to find an answer, although I dont think they do during the day (even if there is no light around the spawner).
+Since the 0.0.19a client update on June 20, 2009, Lava's texture became animated.
-:I'm pretty sure they spawn during the day; after all, mobs can spawn anywhere in darkness, even during the day. Why not around mob spawners? Though to be honest, I'm pretty sure many people's mob farms work during the day, if they keep the spawner enclosed in darkness. - [[User:Taggedjc|JC]] 00:01, 28 September 2010 (UTC)

-I can try and test a few of these things. I post the results here soon. --[[User:WallShadow|WallShadow]] 23:55, 5 October 2010 (UTC) <br> <br>
-Update 1: I have tested  a few things,(note: all of these tests were done with artifical mob spawners(mob spawners i placed using hax), the results might be different for natural mob spawners, as artifical mob spawners can only spawn pigs). <br>
-. mob spawners do work in full daylight <br>
-. mob spawners can ONLY spawn mobs on land. the mob spawner may not spawn mobs into water, on water, or on air(i mean with nothing under it). if a mob spawner is in water, it will only spawn mobs if there is a patch of land near by. <br>
-. artifical mob spawners can still spawn mobs even if you completely surround it with torchs, Im guessing that it works with artifical mob spawners because pigs can spawn both in light and dark, while hostile mobs can only spawn in dark areas. Although thats just my opinion, feel free to state any other possibilities. <br>
-. im guessing by the tests that the spawn radius is about 3-4 blocks away, but im not sure, it is just my educated guess. <br> <br>

-:While I appreciate you taking the time to do tests, I'm afraid they were in vain, as friendly mob spawners '''do''' behave differently to regular mob spawners, and thus most your information does not apply.
-:1. Dungeon spawners do not work in daylight. That's why surrounding them with torches stops them.
-:2. Dungeon spawners do not need land. Pigs only spawn on grass, that's why hacked spawners need grass.
-:3. AFAIK, Pig spawners will '''only''' spawn pigs when properly lit, but I'm not sure.
-:4. I think the spawn radius is about 5 blocks. That's why dungeons are that size.
-:So, yeah... That's what I gotta say about the issue. [[User:Noroom|Noroom]] 01:42, 7 October 2010 (UTC)
+== Features ==
-::Noroom, I just made a pig spawner+grinder+collection method and in my testing, it seems it really does not matter at all whether the spawner itself is lit, but the grass tile in which the pig spawns is lit properly for pigs to spawn.  I could be wrong, but that's what I saw, as I put a wall in between the spawner and the grassy tile, and the spawner was not lit.  I will need to do some more extensive testing.  Also, I am a bit glad they only spawn on grassy tiles so it is easier to control the flow of pigs, but also hard because when you want to make an underground spawner, you need grass.

-:I have done extensive tests with both a zombie spawner and a spider spawner in Beta SSP and no amount of torchlight, including torches placed directly next to the spawner, prevented mobs from spawning. Additionally, the zombie spawner was conveniently close to the surface so I opened the ceiling to sunlight and I can confirm that no zombies were generated when the spawner was exposed to daylight. I have updated this wiki to reflect my findings. --[[User:KADC|KADC]] 10:41, 15 January 2011 (UTC)

-The monster spawner works like regular spawning, i.e. It won't activate unless the user is near it. I don't know how close you have to be for it to start working, but my guess is that it's the same distance as regular spawning. Once the player is close enough the spawner starts generating mobs. Since it only spawns periodically, there is going to be a delay before the mobs start appearing. When you first break into a dungeon, the spawner has been "running" for a while, which is why it's usually full of mobs, but if you run right to it, it may not have had enough time to start spawning yet.

-I had noticed that spawners seem not to function if you are a certain distance away from them. There did not seem to be any information about this on the page, so I did a test. It seem that a spawner will only work if it is within 16 squares of you. I have only tested this horizontally. [[User:slothen42|slothen42]] 15:54 November 08, 2010 (UTC)

-== Pig Spawners and Mob Cap ==
-I've tested out a mob spawner using an inventory editor, which results in spawning a large number of pigs. But, I also recall that there is a limit to the number of mobs that can be on the map at once, with separate counts for hostile and passive mobs. But do pigs spawned by a mob spawner count against the cap for passive mobs? Or are they, being created by a spawner rather than at random, not affected by the normal limit? I do hope they are subject to the normal limit for passive mobs, as the room I put that mob spawner in would have space for a lag-inducingly high number of pigs. --[[User:Valos|Valos]] 17:21, 2 December 2010 (UTC)
-== Mob Spawner Enemies VS Natural Spawn Enemies ==
-I came across a dungeon/cavern today which contained a Skeleton Mob Spawner.
-As I was fighting off the 4 skeletons in there, a fifth skeleton came out from the Cavern and began shooting at the Skeletons spawned by the spawner. (Which made it much easier, as the spawned skeletons were too busy fighting off the cavern skelly to notice me.)
-Is this a bug, or is it meant to happen?
---[[User:Buggyman|Buggyman]] 04:38, 29 December 2010 (UTC)
-When Skeletons shoot, sometimes they accidentally hit another mob. in this case, the skeleton. When that skeleton got hit by the other skeleton it turned hostile against it. All mobs do this. for instance, when a skelton hits a creeper, the creeper will chase the skeleton from then on, as the skeleton will protect itself.
