IACondition

interface IACondition

A cross-loader condition, evaluated at datapack load time, that decides whether the entry it's attached to (a recipe, tag entry, etc.) should be active. Mirrors NeoForge's/Fabric's native condition systems but is decoded through CODEC so the same condition classes work on both loaders.

Built-in implementations live alongside this file (e.g. AAndCondition, AOrCondition, ANotCondition, ATrueCondition, AModLoadedCondition, ARegistryCondition); see ABuiltinConditions for the full set and archie-datagen's AConditionBuilder for a DSL to combine them. Register custom conditions with register.

object Companion

IContext

interface IContext

Read-only view of loaded tags/registries available to test while a condition is evaluated.

Properties

codec

abstract val codec: MapCodec<out IACondition>

The codec used to (de)serialize this condition to/from JSON.

identifier

abstract val identifier: ResourceLocation

The condition type's registered id, matching the key it was registered under.

neoforge

val IACondition.neoforge: NeoForgeCondition

Wraps this condition as a NeoForge ICondition. Public so archie-datagen can attach conditions to generated recipes.

val MapCodec<out IACondition>.neoforge: MapCodec<NeoForgeCondition>

Wraps this codec as a NeoForge condition-serializer codec.

Functions

test

abstract fun test(context: IACondition.IContext): Boolean

Evaluates this condition against context, returning whether it holds.
