Tutorial:TNT cannons

A TNT cannon is a mechanism that launches entities using TNT. They can be used in survival to mine, fast travel and destroy. Cannons built in survival often follow premade blueprints. In creative, on the other hand, cannons might be built to experiment with one's redstone skills or have fun in general.

Over the years communities have emerged around cannon-PVP and created constraints on the cannons to increase fun when fighting. A limit on the use of blocks, especially those with high blast resistance, is the most common constraint. In WarGear and Slime Block Robot Battles, the fighting machines are built in creative and then are copied to an arena where combat takes place in survival. The size of both is constrained. Dispensers and some entities (and for WarGear also duplication bugs) are prohibited. SBRT requires the whole fighting machine to be movable. Factions bases, on the other hand, are built in survival, though they might be designed in creative. Dispenser cannons and water shielding are allowed here. Those constraints and the absence of constraints have caused a great amount of cannon diversity, which is discussed in this article.
