[SOLVED][1.17.1]how do i make a custom tree decorator

[the_lizard_king]

I am trying to add a custom tree trunk decorator to my custom tree which would put blocks around the trunk of the tree like cocoa beans.

did you looked at the vanilla code?

[the_lizard_king]

I copied the cocoa placer but I'm not sure what to return here

protected TreeDecoratorType<?> type() {
	      return null;
	   }

I tried just TreeDecoratorType.COCOA but that didn't work

it's the TreeDecoratorType minecraft use it for Registry look how minecraft register/create them and copy the logic for your TrunkPlacer

I copied the TreeDecoratorType now it just crashes when I try to create a world with the message

"Can not register to a locked registry. Modder should use Forge Register methods."

here's my tree decorator type code

public class ModTreeDecoratorType<P extends TreeDecorator> extends ForgeRegistryEntry<ModTreeDecoratorType<?>> {
	public static final TreeDecoratorType<MushroomTrunkDecorator> TRUNK_MUSHROOM = register("trunk_mushroom", MushroomTrunkDecorator.CODEC);
	private final Codec<P> codec;

	   @SuppressWarnings("deprecation")
	private static <P extends TreeDecorator> TreeDecoratorType<P> register(String p_70053_, Codec<P> p_70054_) {
	      return Registry.register(Registry.TREE_DECORATOR_TYPES, p_70053_, new TreeDecoratorType<>(p_70054_));
	   }

	   public ModTreeDecoratorType(Codec<P> p_70050_) {
	      this.codec = p_70050_;
	   }

	   public Codec<P> codec() {
	      return this.codec;
	   }
}

ups sorry, i forgot that TreeDecoratorType use now the Forge Registry system you could simply extends TreeDecoratorType and register it like Block or Items via DeferredRegister or the RegistryEvents

Druidcraft has some nice examples on what you are looking for I guess.
