Creating additional models

To create a new model you must create your own java class that extends PlayerLookModelManager interface of the addon.

public class CustomModelManager implements PlayerLookModelManager {
    @override
    public void setAngles(LivingEntity entity, float limbAngle, float limbDistance, float animationProgress, float headYaw, float headPitch, PlayerLookModel<?> model) {
    }

    @override
    public boolean onRender(Pair<Identifier, List<String>> modelType, LivingEntity entity, PlayerLookModel<?> model) {
        return true;
    }

    @override
    public void addTexturedModelData(ModelData modelData) {
    }

    @override
    public void setVisible(boolean visible, PlayerLookModel<?> model) {
    }
}

In the addTexturedModelData method you can use addon's ModelPartData and add your custom model part to it.

In the setVisible method you must put visibility change functions of your custom model.

In the setAngles method you can create animations for your custom parts.

In the onRender method you can do changes in the model right before the rendering and return should the model part be rendered or not.

After that you must register your model manager using PlayerLookModelManagerRegistry. Write this in the onInitializeClient() method of your mod.

public class YourModClient implements ClientModInitializer {
    @Override
    public void onInitializeClient() {
        PlayerLookModelManagerRegistry.register(new CustomModelManager())
    }
}
