[1.16] Overwrite player

[RobinCirex]

Hey,

I'm trying to make an animated player model using GeckoLib. For that, the player has to implement the interface "IAnimatable". How do I overwrite the player class so I can implement it? 
This is what I've tried

package me.cirex.titans.entity;

import com.mojang.authlib.GameProfile;

import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import software.bernie.geckolib3.core.IAnimatable;
import software.bernie.geckolib3.core.manager.AnimationData;
import software.bernie.geckolib3.core.manager.AnimationFactory;

public class CustomPlayerEntity extends PlayerEntity implements IAnimatable {

	public CustomPlayerEntity(World p_i241920_1_, BlockPos p_i241920_2_, float p_i241920_3_, GameProfile p_i241920_4_) {
		super(p_i241920_1_, p_i241920_2_, p_i241920_3_, p_i241920_4_);
		System.out.println("Player was created");
	}

	@Override
	public boolean isSpectator() {
		return false;
	}

	@Override
	public boolean isCreative() {
		return false;
	}

	@Override
	public void tick() {
		System.out.println("test");
		super.tick();
	}

	@Override
	public void registerControllers(AnimationData data) {
		
	}

	@Override
	public AnimationFactory getFactory() {
		return null;
	}

}

package me.cirex.titans.registry;

import me.cirex.titans.entity.CustomPlayerEntity;
import net.minecraft.entity.EntityClassification;
import net.minecraft.entity.EntityType;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;

public class TitanRegistry {

	public static final EntityType<?> playerType = EntityType.Builder
			.<CustomPlayerEntity>create(EntityClassification.MISC).disableSerialization().disableSummoning()
			.size(0.6F, 1.8F).trackingRange(32).func_233608_b_(2).build("minecraft:player").setRegistryName("minecraft:player");

	@SubscribeEvent
	public void onRegisterEntity(RegistryEvent.Register<EntityType<?>> event) {
		if(event.getName().getPath().equalsIgnoreCase("player")) {
			event.setCanceled(true);
		}
		
		event.getRegistry().register(playerType);
	}

}

You cannot.

 

If this is true, report this bug to the library authors. They should be using capabilities.

Okay, thank you
