TNT

TNT is an explosive block.

Obtaining
TNT can be mined with any tool.

The newly added "old TNT" block can only be obtained via commands, mods or hacks. When it is broken, it will activate (as opposed to regular TNT dropping itself).

Natural generation
TNT occurs naturally in Desert Temple traps.

Usage


TNT blocks can be activated by:
 * being with flint and steel
 * a powered redstone current
 * being shot with a Flame-enchanted arrow
 * being placed by a dispenser
 * being hit by a fire charge
 * coming into contact with spreading fire or lava
 * being in the blast radius of a nearby explosion, including that of another TNT block

Behavior
Once activated, TNT turns into an entity. It is spawned at the center (+0.5,+0.5,+0.5) of a powered TNT block, while itself is a cube with an edge length of 0.98. Its fuse lasts 40 redstone ticks (4 seconds/80 game ticks) if activated by redstone or fire, or a random number between 10 to 30 game ticks (.5 to 1.5 seconds) if it's destroyed by an explosion.

Primed TNT's texture blinks, with its texture alternating between its standard texture and a pure white texture. The texture will blink at a rate of 2 times per second.

Once spawned, primed TNT is given a vertical velocity of 0.2 m/tick, and a horizontal velocity of 0.02 m/tick in a random direction. If it does not collide with another block, it will travel 0.166m horizontally on flat ground before it stops.

When the countdown timer expires, the TNT explodes. The explosion has an explosive force of 4.

Redstone component
For redstone to activate TNT, it must lead directly to the TNT, or power an adjacent block.

Traps
TNT traps can be used in variety of traps. The simplest of them - a land mine - is made of TNT connected to a pressure plate or tripwire with redstone.

Other uses
Because they are destroyed in one hit, they can be used in spleef arenas. They work better than dirt or other materials and do not need a tool to be destroyed. This use depends on no player coming in with items that could be used to activate TNT; or else a plugin that disables explosions can be used.

Data values
TNT uses one ID name:. It uses block data to determine, whether the TNT should activate when broken. It also uses block states, which will replace block data in the future.

Trivia

 * "TNT" stands for Trinitrotoluene.
 * However, the use of sand in the crafting recipe references dynamite, a different high explosive consisting of nitroglycerine mixed with diatomaceous earth (which is mostly silica, the same chemical compound as yellow sand).
 * An activated or "primed" block of TNT will fall 77 blocks before exploding.
 * Destroying TNT makes the same sound as destroying a grass block.
 * Similar to arrows, primed TNT will catch on fire if it is shot through lava.
 * Primed TNT will explode immediately if summoned on default. That is because the fuse of the summoned TNT is 0 ticks unless specified via data tags.
 * If TNT is blown up just as an arrow passes by, then the arrow is redirected opposite of the blast.
 * TNT and Slime Blocks are the only solid block that breaks instantly (When not in creative).
 * Although Flint & Steel cannot light fires in Adventure Mode, it can still ignite TNT.
 * While under the effects of a Potion of Night Vision, TNT will appear full bright as usual, but will ignore the potion's effect and take on the light around it when primed, because it's an entity when it's primed.
 * If TNT, when primed, hops up and just barely lands on a block directly below and next to it, and then slides off, the TNT will fall, but the explosion will appear where the TNT almost landed before sliding off.
 * By combining TNT cannons and player launching devices, one can make a "firework base" that shoots TNT into the air, letting it explode like professional-grade fireworks in real life. This is more impressive in skill than real fireworks, since the smoke effect will be distinguishable from fireworks.
 * When the player primes TNT and the primed block falls into the end, the TNT block will detonate when the player enters the end. This gives the player an opportunity to detonate hundreds of TNT blocks instantaneously. However it is not advised because if the player puts too much TNT in the portal, when the player enters the end, the game may crash.
 * You can see primed TNT from about (at the most) 70 blocks away.
 * As of 1.5, Mobs killed by player-ignited TNT (via Flint and Steel or by flaming arrows) will drop EXP orbs as though they were killed by the player in regular combat. This makes for effective EXP and mob drop farming.
 * TNT ignited via redstone signals or fire will otherwise cause mobs to drop no EXP.
 * The crafting recipe for TNT (sand and gunpowder) may be a reference to the fact that early gunpowder was made by mixing powders together (sulfur, saltpeter and charcoal), and to the fact that Creeper gunpowder used to be called Sulfur. Real-life TNT is made by repeatedly treating toluene with concentrated nitric and sulfuric acids.
 * When primed TNT is directed towards a Nether Portal, it will only pass through said blocks and not travel into the Nether. (Tested with a TNT cannon).
 * Although primed TNT will get caught in cobwebs, TNT propelled fast enough will fly through them without slowing down at all.
 * A consistent method of crashing Minecraft is to start a superflat world with a layer of TNT, then set it off. The number of concurrent explosions rises exponentially to infinity. The game will crash shortly after due to the unimaginable explosions. The map will become unplayable forever until it is deleted.
 * It takes 19.75 blocks to fall for it to reduce the timer for one second.
 * TNT does no damage to the player in water in the Xbox 360 version of Minecraft.
 * One block of TNT appears to be a bundle of 16 sticks of dynamite (TNT). If the top of the block is examined, a fuse texture can be made out with individual strings connecting to 16 white squares, indicating the TNT block is a cluster bomb of sorts.
