Pandaw

I extend LivingEntity, but MobEntity already extends LivingEntity, so I could just replace it right ?

Good point

Omg it spawns without crashing 😭 It shows the Name tho Like a nametag. I've read something about that today, I'll have to check my code to remove that I guess

I noticed the stupid reason why it didn't resolve them Here's my new code, tho I don't know if I should personnalize it or leave it like that ? package com.pandaw.magical_macrocosm.entities; import net.minecraft.entity.EntityType; import net.minecraft.entity.LivingEntity; import net.minecraft.entity.MobEntity; import net.minecraft.entity.ai.attributes.AttributeModifierMap; import net.minecraft.entity.ai.attributes.Attributes; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.inventory.EquipmentSlotType; import net.minecraft.item.ItemStack; import net.minecraft.network.datasync.DataParameter; import net.minecraft.network.datasync.DataSerializers; import net.minecraft.network.datasync.EntityDataManager; import net.minecraft.util.*; import net.minecraft.world.World; import javax.annotation.Nullable; public class PixieEntity extends LivingEntity { private static final DataParameter<Byte> AI_FLAGS = EntityDataManager.createKey(MobEntity.class, DataSerializers.BYTE); private final NonNullList<ItemStack> inventoryHands = NonNullList.withSize(2, ItemStack.EMPTY); private final NonNullList<ItemStack> inventoryArmor = NonNullList.withSize(4, ItemStack.EMPTY); public boolean isLeftHanded() { return (this.dataManager.get(AI_FLAGS) & 2) != 0; } public PixieEntity(EntityType<? extends LivingEntity> type, World worldIn) { super(type, worldIn); } protected void registerGoals() { } public static AttributeModifierMap.MutableAttribute setAttribute() { return MobEntity.func_233666_p_() .createMutableAttribute(Attributes.MAX_HEALTH, 4.0f) .createMutableAttribute(Attributes.FLYING_SPEED, 10.0f); } @Override protected int getExperiencePoints(PlayerEntity player) { return 2; } protected SoundEvent getAmbientSound() { return SoundEvents.ENTITY_BEE_POLLINATE; } @Override protected SoundEvent getHurtSound(DamageSource damageSourceIn) { return SoundEvents.ENTITY_BEE_HURT; } @Nullable @Override protected SoundEvent getDeathSound() { return SoundEvents.ENTITY_BEE_DEATH; } /*@Override public Iterable<ItemStack> getArmorInventoryList() { return null; }*/ public Iterable<ItemStack> getArmorInventoryList() { return this.inventoryArmor; } /*@Override public ItemStack getItemStackFromSlot(EquipmentSlotType slotIn) { return null; }*/ public ItemStack getItemStackFromSlot(EquipmentSlotType slotIn) { switch(slotIn.getSlotType()) { case HAND: return this.inventoryHands.get(slotIn.getIndex()); case ARMOR: return this.inventoryArmor.get(slotIn.getIndex()); default: return ItemStack.EMPTY; } } /*@Override public void setItemStackToSlot(EquipmentSlotType slotIn, ItemStack stack) { }*/ public void setItemStackToSlot(EquipmentSlotType slotIn, ItemStack stack) { switch(slotIn.getSlotType()) { case HAND: this.inventoryHands.set(slotIn.getIndex(), stack); break; case ARMOR: this.inventoryArmor.set(slotIn.getIndex(), stack); } } /*@Override public HandSide getPrimaryHand() { return null; }*/ public HandSide getPrimaryHand() { return this.isLeftHanded() ? HandSide.LEFT : HandSide.RIGHT; } } I still don't know how to put goals tho.

You mean like : public Iterable<ItemStack> getArmorInventoryList() { return this.inventoryArmor; } public ItemStack getItemStackFromSlot(EquipmentSlotType slotIn) { switch(slotIn.getSlotType()) { case HAND: return this.inventoryHands.get(slotIn.getIndex()); case ARMOR: return this.inventoryArmor.get(slotIn.getIndex()); default: return ItemStack.EMPTY; } } public void setItemStackToSlot(EquipmentSlotType slotIn, ItemStack stack) { switch(slotIn.getSlotType()) { case HAND: this.inventoryHands.set(slotIn.getIndex(), stack); break; case ARMOR: this.inventoryArmor.set(slotIn.getIndex(), stack); } } public HandSide getPrimaryHand() { return this.isLeftHanded() ? HandSide.LEFT : HandSide.RIGHT; } ? That's what happens when I say ; It cannot resolve inventoryArmor/Hands and isLeftHanded.

I've checked several Entity classes and they either don't have those methods (Chicken, Sheep, Zombie etc), or don't implement them a way that would work here. I've looked the Player Entity and it has those methods but when I try to rewrite them the same way, I get errors. Honestly, I'm just lost. How should I implement them ? When I try to remove them, it says the class needs to be abstract or implement those abstract methods. I've tried to look on different forums and stuff, and I just can't find what to do. Also, I don't know where to put goals ? When I try the registerGoals() method, it doesnt show what should be put next (I've tried to do it as in the Entity classes I've looked at).

Hi ! I've tried to create an entity, with its 3 classes, XEntity, XEntityModel, and XEntityRenderer. I've looked into the vanilla classes, and even though there are differences, I don't see anything that would be critical missing or something (to the best of my knowledge obviously). When I try to summon my entity, a crash occurs with the following crash report : ---- Minecraft Crash Report ---- // Shall we play a game?

HI ! So I tried to add a sword using a custom class and and ItemTier class.
