Overview

Fluid Tick Structure Processor is a utility mod that ensures all fluids inside generated structures begin flowing immediately after generation.

By default, fluids placed in structures remain static until they receive a block update. This mod solves that issue by automatically ticking all fluid blocks inside the structure as soon as it is loaded.

Key Feature

Adds a new structure processor: fluid_tick_structure_processor:fluid_tick

Function

When a structure using this processor is placed in the world:

The processor searches for all fluid blocks within the structure.
Each fluid block is scheduled for a fluid tick.
As a result, water, lava, and other modded fluids begin flowing right after generation.

Application

You can apply the processor to any structure through a datapack. Example usage:

{
  "elements": [
    {
      "weight": 1,
      "element": {
        "element_type": "minecraft:single_pool_element",
        "projection": "rigid",
        "location": "test:test",
        "processors": [
          {
            "processor_type": "fluid_tick_structure_processor:fluid_tick"
          }
        ]
      }
    }
  ],
  "fallback": "minecraft:empty"
}

Effects on Gameplay

Prevents “frozen” water or lava inside generated structures.
Makes structures with fluid features behave naturally.
Has no impact on gameplay beyond fluid behavior.
Fully data-driven and compatible with other structure or fluid mods.
