Hello, everyone! As many of you have discovered since Bukkit was created, there is currently no event fired when a TNT block is detonated (switching from the block state to the blinking entity). And no, it is not the ExplosionPrimeEvent, which gets called just before the explosion. It is high time that we create such an event. I suggest BlockDetonateEvent as a name, but maybe you have better ideas? Some people favor moving ExplosionPrimeEvent to when the TNT block is detonated, but as some plugins actually use this event for it's current functionality, I think a better solution would be to leave it as it is and create a new event. Another question : If the event is canceled, should the TNT disappear or stay? There are several places it can be called : a player with flint and steel, fire, the TNT's physics (redstone) or the TNT is exploded I have made a pull request for both bukkit and craftBukkit (they may be a bit outdated now), so please feel free to review them and to suggest improvements. https://github.com/Bukkit/Bukkit/pull/708 https://github.com/Bukkit/CraftBukkit/pull/955 I really wish this issue can be resolved quickly, because many plugins could use such an event. Thank you!
