Class VariantBlockStateBuilder

java.lang.Object

net.minecraftforge.client.model.generators.VariantBlockStateBuilder

All Implemented Interfaces:

IGeneratedBlockState

public class VariantBlockStateBuilder
extends Object
implements IGeneratedBlockState

Builder for variant-type blockstates, i.e. non-multipart blockstates. Should not be manually instantiated, instead use BlockStateProvider.getVariantBuilder(Block).

Variants can either be set via setModels(PartialBlockstate, ConfiguredModel...) or addModels(PartialBlockstate, ConfiguredModel...), where model(s) can be assigned directly to partial states, or builder style via partialState() and its subsequent methods.

This class also provides the convenience methods forAllStates(Function) and forAllStatesExcept(Function, Property...) for cases where the model for each variant can be decided dynamically based on the state's property values.

getOwner

public Block getOwner()

toJson

public com.google.gson.JsonObject toJson()

Specified by:

toJson in interface IGeneratedBlockState

addModels

public VariantBlockStateBuilder addModels(VariantBlockStateBuilder.PartialBlockstate state,
 ConfiguredModel... models)

Assign some models to a given partial state.

Parameters:

state - The partial state for which to add the models

models - A set of models to add to this state

Returns:

this builder

Throws:

NullPointerException - if state is null

IllegalArgumentException - if models is empty

IllegalArgumentException - if state's owning block differs from the builder's

IllegalArgumentException - if state partially matches another state which has already been configured

setModels

public VariantBlockStateBuilder setModels(VariantBlockStateBuilder.PartialBlockstate state,
 ConfiguredModel... model)

Assign some models to a given partial state, throwing an exception if the state has already been configured. Otherwise, simply calls addModels(PartialBlockstate, ConfiguredModel...).

Parameters:

state - The partial state for which to set the models

model - A set of models to assign to this state

Returns:

this builder

Throws:

IllegalArgumentException - if state has already been configured
