Fluid Definitions - Subtle Effects

Fluid Definitions are used to tell the mod about all the different objects related to a fluid, such as fluid buckets or cauldrons, as well as defining a few default settings for a fluid.

Setup

Create a new JSON file in the assets/{namespace}/subtle_effects/fluid_definitions folder of a resource pack. Inside this file, add the source and flowing string elements. These elements are the minimum requirement for a fluid definition and define the IDs of the source and flowing fluid types.

{
  "source": "minecraft:water",
  "flowing": "minecraft:flowing_water"
}

Name	Required	Description
`source`	Yes	String ID of a source fluid
`flowing`	Yes	String ID of a flowing fluid
`cauldron`	No	String ID of a block that inherits from the `AbstractCauldronBlock` class
`splash_type`	No	String ID of a Splash Type. The ID for a splash type is the namespace defining it followed by the path relative to the `/subtle_effects/splash_types` folder. For example, the path for the water splash type is: `assets/minecraft/subtle_effects/splash_types/water_splash.json` and it's ID is: `minecraft:water`. For a splash type in a subfolder e.g. `assets/examplepack/subtle_effects/splash_types/example_path/example.json` the ID would be: `examplepack:example_path/example`
`bucket_item`	No	String ID of an item that inherits from the `BucketItem` class
`droplets`	No	A Droplet Options object used for bucket interaction effects and as a fallback for Splash Types
`light_emission`	No	Integer from 0 to 15. Controls brightness for splash particles
