NoBadBooms

The gamerule tntExplodes is true by default, which keeps vanilla behavior. When a server owner sets it to false, TNT still ignites, detonates with its fuse, sound, particles and knockback, and still damages entities, but no blocks are destroyed. The mod listens for the ExplosionEvent.Detonate event, which fires after the explosion is computed, and clears the affected blocks from the list. The setting is saved per world, like other vanilla gamerules. Only the server needs the jar in its mods folder, and players on unmodded vanilla clients can connect without any change. Single-player works too when the mod is installed on the client. Released under the MIT License, the code is open source.
