[1.14.4] Deserializing NBT on the client


Tschipp

Recommended Posts

I have a contraption that renders static entities, meaning the entities don't exist in the world.

The entity NBT must be read before the render to conserve information such as sheep color or entity age.

This used to work fine for all cases in 1.12, but I'm having trouble with Villagers and Foxes.

 

I'll illustrate my issue for foxes:

 

First, I call IForgeEntity#deserializeNBT.

That then calls Entity#read, which eventually calls Entity#readAdditional.

 

For foxes, that method then calls a method of FoxEntity called "func_213501_ej".

That function adds attack goals to the fox. Problem is, that those attack goals haven't been initialized yet and are null, causing a NPE further down the line in the TargetSelector class.

 

One potential solution that I see for this is that I call MobEntity#registerGoals before the NBT read. However, I would need to use reflection for that.

MobEntity#registerGoals is usually called from the MobEntity constructor but registerGoals only gets executed when the world is not remote. 

 

But I wonder, how does vanilla do it? I mean the game reads the NBT on the client at some point, but doesn't get any crashes from uninitialized AI Goals...

Am I calling the wrong serialize/deserialize functions?

It does not.

Yeah, after a few hours of stepping through the debugger I noticed that too... How does the client then acquire an updated version of entities from the server? Is it a packet? (Probably)

 

Do you see any other solution for my problem?

    • Update: I managed to make the item not disappear after crafting, but it doesn't remove any durability. import net.minecraft.enchantment.EnchantmentHelper; import net.minecraft.enchantment.Enchantments; import net.minecraft.enchantment.UnbreakingEnchantment; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; public class NuggetHammer extends Item { private boolean damage; public NuggetHammer(Properties p_i48487_1_) { super(p_i48487_1_); } @Override public int getMaxDamage(ItemStack stack) { return 54 - 1; } public boolean isBarVisible(ItemStack stack) { return false; } @Override public ItemStack getContainerItem(ItemStack stack) { ItemStack copy = stack.copy(); copy.setCount(1); if (!this.damage) return copy; int unbreaking = EnchantmentHelper.getItemEnchantmentLevel(Enchantments.UNBREAKING, stack); for (int i = 0; i < unbreaking; i++) { if (UnbreakingEnchantment.shouldIgnoreDurabilityDrop(stack, unbreaking, random)) return copy; } copy.setDamageValue(stack.getDamageValue() + 1); if (copy.getDamageValue() > stack.getMaxDamage()) return ItemStack.EMPTY; return copy; } }
