ItemOverrides

ItemOverrides provides a way for an BakedModel to process the state of an ItemStack and return a new BakedModel; thereafter, the returned model replaces the old one. ItemOverrides represents an arbitrary function (BakedModel, ItemStack, ClientLevel, LivingEntity, int) → BakedModel, making it useful for dynamic models. In vanilla, it is used to implement item property overrides.

ItemOverrides()

Given a list of ItemOverrides, the constructor copies and bakes the list. The baked overrides may be accessed with #getOverrides.

resolve

This takes an BakedModel, an ItemStack, a ClientLevel, a LivingEntity, and an int to produce another BakedModel to use for rendering. This is where models can handle the state of their items.

This should not mutate the level.

getOverrides

Returns an immutable list containing all the BakedOverrides used by this ItemOverrides. If none are applicable, this returns the empty list.

BakedOverride

This class represents a vanilla item override, which holds several ItemOverrides$PropertyMatcher for the properties on an item and a model to use in case those matchers are satisfied. They are the objects in the overrides array of a vanilla item JSON model:

{
  // Inside a vanilla JSON item model
  "overrides": [
    {
      // This is an ItemOverride
      "predicate": {
        // This is the Map<ResourceLocation, Float>, containing the names of properties and their minimum values
        "example1:prop": 0.5
      },
      // This is the 'location', or target model, of the override, which is used if the predicate above matches
      "model": "example1:item/model"
    },
    {
      // This is another ItemOverride
      "predicate": {
        "example2:prop": 1
      },
      "model": "example2:item/model"
    }
  ]
}
