Minecart with TNT

The minecart with TNT is a block of TNT inside a minecart.

Crafting
Minecarts with TNT cannot be retrieved by attacking them, as they will just drop a minecart and a TNT. Still, they are renewable since the player just has to go through the trouble of recrafting them.

Usage
Minecart with TNT will detonate on these conditions:
 * It moves over a powered Activator Rail (after 4 second delay like the TNT block).
 * It is hit by a fire charge (also with a 4 second delay)
 * It hits the ground with a downward velocity of it falling more than three blocks, unless landing on any form of rail.
 * It is destroyed while in motion. (Does not explode if destroyed by a player in Creative mode.)
 * It is destroyed by fire, lava or an explosion.
 * It turns on a curved track too fast, with a solid block or entity located beside the track (in the previous movement direction).
 * It is hit by a flaming arrow. (Explosion size is dependent on the speed of the arrow)
 * It is pressed into a block or entity and has velocity.

Upon detonation, it will act as normal TNT, exploding and damaging nearby scenery, players, and entities. Upon detonation after activating on activator rail, it will not destroy its rails and the blocks the rail is on, however other nearby carts can. The faster the minecart, the more powerful the explosion.

Minecart with TNT will bounce off of other minecarts and cannot be linked to a Minecart with Furnace.

Entity data
Minecarts with TNT have entity data associated with them that contain various properties of the entity. Their entity ID is.

Trivia

 * A direct hit from three merged minecarts with TNT can reduce a fully diamond armored player to half a heart.
