I would like to know if there is a way to make it so when a player places a block of TNT, it immediately fuses, without the use of flint and steel, fire charges, etc.

Please, no mods or plugins.


If you want to use a command block to remotely prime it, just use /setblock <coordinates> minecraft:redstone_torch to place a redstone torch next to the TNT (you can replace minecraft:redstone_torch with anything that would output a signal like).

Otherwise, if you want TNT to be primed when placed, you could use /fill replacing TNT with primed TNT, i'm not sure of primed YNY's data value though. To have it keep executing just use this clock.

  • I know all that stuff that's what the etc. was for but I just want it so when someone places it on the ground in an enclosed room it automatically sets off just using Command Blocks and TNT thats all – FireStrike289 Nov 14 '14 at 2:42
  • @FireStrike289 missed the command block part, think the edit should do it – Memor-X Nov 14 '14 at 2:54
  • Using /setblock implies that the Command Block knows where the TNT is gonna get places in this I want you to be able to place it wherever you want. Also the room I'm talking about it a 71x71 circular room with a 36 block high dome I have mobGriefing off but the TNT is to kill mobs like a weapon but you need to be able to place it wherever you want – FireStrike289 Nov 14 '14 at 3:11
  • @FireStrike289 edited adding in method for using /execute and /fill, though i'm not entirely sure of the results, in theory it should work if you set the xyz/xyz2 values of /fill to cover your room – Memor-X Nov 14 '14 at 3:33
  • I'm not sure how to use /execute so if you could tell me I guess I can accept your answer. Thanks in advance – FireStrike289 Nov 14 '14 at 3:37

Skip the first command block chain and go straight to the one that uses TNT (1:13) Btw I did not make this video

    Maybe summarize the key points in case the video goes down? – Dragonrage Aug 15 '16 at 23:37
