Fixed Explosions

Fixed Explosion

Fixed Explosion is a server-side Fabric mod that improves Minecraft explosions while keeping them vanilla-looking. The mod is built around one simple idea: TNT should be able to carry explosion data like entities already do, and large TNT setups should explode in a cleaner, smarter, more optimized way. Fixed Explosion optimizes TNT chain reactions by merging connected or nearby TNT into fewer stronger explosions instead of forcing Minecraft to process every TNT as a separate blast. This helps large TNT builds, TNT lines, towers, traps, and modded super TNT behave more naturally while reducing unnecessary lag. It also improves large explosions by smoothing crater generation, reducing useless item drops near the blast center, cleaning nearby item entities, supporting liquid behavior options, and preventing very large explosions from breaking into ugly or useless shapes. The goal is to make vanilla explosions feel like they should have worked by default, while giving mod developers, datapack creators, map makers, and server owners simple tools to create better TNT without replacing the vanilla TNT block. Compatible Explosion Sources Fixed Explosion supports: TNT item Placed TNT block Primed TNT entity TNT minecart item TNT minecart entity Creepers Creeper spawn eggs Large fireballs TNT Item Default TNT values: power:4f fuse:80 ignore_liquids:false break_liquids:false

/give @p minecraft:tnt[explosion={power:4f,fuse:80,ignore_liquids:false,break_liquids:false}]

Place it like normal TNT. When ignited, the primed TNT uses those values. TNT Block Commands Use /setblock: /setblock ~ ~ ~ minecraft:tnt[unstable=false,power:4f,fuse:80,ignore_liquids:false,break_liquids:false] Use /fill: /fill ~ ~ ~ ~4 ~ ~ minecraft:tnt[unstable=false,power:4f,fuse:80,ignore_liquids:false,break_liquids:false] Primed TNT /summon minecraft:tnt ~ ~ ~ {explosion:{power:4f,fuse:80,ignore_liquids:false,break_liquids:false}} TNT Minecart Item Default TNT minecart values: ExplosionPower:4f Fuse:80 ignore_liquids:false break_liquids:false /give @p minecraft:tnt_minecart[explosion={ExplosionPower:4f,Fuse:80,ignore_liquids:false,break_liquids:false}] TNT Minecart Entity /summon minecraft:tnt_minecart ~ ~ ~ {ExplosionPower:4f,Fuse:80,ignore_liquids:false,break_liquids:false} Creeper Spawn Egg Default creeper values: ExplosionRadius:3 Powered:false ignore_liquids:false break_liquids:false /give @p minecraft:creeper_spawn_egg[explosion={ExplosionRadius:3,Powered:false,ignore_liquids:false,break_liquids:false}] Creeper Entity /summon minecraft:creeper ~ ~ ~ {ExplosionRadius:3,Powered:false,ignore_liquids:false,break_liquids:false} Large Fireball Default fireball value: ExplosionPower:1 /summon minecraft:fireball ~ ~ ~ {ExplosionPower:1,ignore_liquids:false,break_liquids:false} Added Data For /give item components: explosion: Fixed Explosion item data container. power: TNT explosion strength. fuse: TNT fuse time in ticks. ExplosionPower: TNT minecart explosion strength. Fuse: TNT minecart fuse time. ExplosionRadius: Creeper explosion size for spawn eggs. Powered: Makes creeper spawn eggs create charged creepers. ignore_liquids: Lets explosions pass through water or lava instead of being blocked. break_liquids: Lets explosions remove water or lava hit by the blast. For /setblock and /fill TNT blocks: power fuse ignore_liquids break_liquids For /summon: TNT uses Fixed Explosion’s explosion:{...} data. Creepers still use vanilla ExplosionRadius and Powered. Fireballs still use vanilla ExplosionPower. Fixed Explosion adds ignore_liquids and break_liquids support to compatible explosion entities. Fixed Explosion is useful for survival servers, technical players, map makers, datapack creators, and mod developers who want stronger, cleaner, more flexible explosions while still using Minecraft’s normal TNT and explosion style.
