The entity registry method, I had moved the method so that you can see which methods are causing the problem

It's after it's registered

    	ModEntities.loadCreatures();
    	ModEntities.loadOthers();
    	ModEntities.loadSpawns();

--EDIT---

I just noticed that there's a method that registers some more entities after the spawns are loaded, and now it works now (and spawning the entities also). Thanks!

- [1.21.3] How to add effects to food?
  
  By Biviss · Posted 1 hour ago
  
  Hi! I just started learning forge yesterday and ran into the same issue. I couldn’t find any documentation about these changes, but I found a way to add effects to food like this: public class ChakChakItem extends Item { private static final FoodComponent FOOD_COMPONENT = new FoodComponent.Builder() .nutrition(16) .saturationModifier(0.4f) .build(); private static final ConsumableComponent CONSUMABLE_COMPONENT = ConsumableComponents.food() .consumeEffect(new ApplyEffectsConsumeEffect( new StatusEffectInstance(StatusEffects.SPEED, 15 * 20, 1), 1.0f)) .build(); public ChakChakItem() { super(new Item.Settings() .food(FOOD_COMPONENT, CONSUMABLE_COMPONENT) .registryKey(RegistryKey.of( RegistryKeys.ITEM, Identifier.of(ChakChakMod.MOD_ID, "chak_chak") ))); } } If the code isn’t perfect, I apologize. Hopefully, others here can help us find a better solution.
