When a TNT block or other explosive goes off, it will turn all blocks into falling blocks, and then shoot them off with a vector away from the source explosion. All drops are cancelled. Have fun!
All it does, is convert the blocks that n explosion would normally destroy into FallingBlock entities. It then shoots those entities off in different directions. Also it will not run the method if the event is cancelled (in the case of worldguard cancelling explosive block damage)
