借助数据包，本模组允许你在流体（例如岩浆、水）流动时产生一个方块（例如岩浆流动遇水时可以不再是产生黑曜石，能够自定义任何方块）、导致一阵爆炸或执行一个 .mcfunction 文件。

方块文件示例：

{ "flowing": "#minecraft:lava", "blocks_nearby": [ "minecraft:diamond_block", "minecraft:beacon", "#minecraft:water" ], "result": { "type": "block", "block": "minecraft:diamond_ore" } }

爆炸文件示例：

{ "flowing": "#minecraft:lava", "blocks_nearby": [ "minecraft:obsidian", "#minecraft:water" ], "result": { "type": "explosion", "power": 2 } }

.mcfunction 文件示例：

{ "flowing": "#minecraft:lava", "blocks_nearby": [ "minecraft:wither_skeleton_skull", "minecraft:creeper_head", "minecraft:soul_sand" ], "result": { "type": "function", "function": "test:test_function" } }
mcfunction：fill ~-2 ~-2 ~-2 ~2 ~2 ~2 air summon lightning_bolt ~ ~ ~ summon wither ~ ~ ~ {Invul:1}
