[Forge 1.10.2] How to create multi-block structure (3x3 and the entity sit in) that find entity and convert it into a spawn egg?

[lethinh]

Could you guys tell me know how to do that?

[Jay Avery]

That is another extremely broad question. This forum isn't for getting people to write your code for you. What have you got so far, and what problems are you having?

I'm having a problem that I don't know how to check whether the entity match the spawn egg or not

Use EntityList.getKey(Entity) to get the registry name of an entity, check if that registry name exists as a key in EntityList.ENTITY_EGGS (i.e. the entity has a spawn egg registered) and then create an ItemStack of Items.SPAWN_EGG with the registry name in the NBT.

 

Look at ItemMonsterPlacer.applyEntityIdToItemStack to see the NBT structure you need to create for the spawn egg. You can't use the method directly because it's client-only.

But there is no method getKey and field ENITITY_EGGS in EntityList

That advice was for 1.11.2, I missed that you were using 1.10.2.

 

In 1.10.2, use EntityList.getEntityString to get the registry name of an entity instead of using EntityList.getKey. The rest of my previous post still applies to 1.10.2.

 

EntityList.ENTITY_EGGS should exist in 1.10.2 if you're using recent MCP mappings. If it doesn't exist in your workspace, either update your mappings or look for the field with type Map<String, EntityList.EntityEggInfo>.

I have followed what you said but didn't work. It didn't spawn the correct spawn egg. Here is my code:

 

public boolean itemInteractionForEntity(ItemStack stack, EntityPlayer playerIn, EntityLivingBase target,
            EnumHand hand) {
        if (target.worldObj.isRemote || !(target instanceof EntityAnimal) || target instanceof EntityMob) {
            return false;
        }

        String entityId = EntityList.getEntityString(target);

        if (EntityList.ENTITY_EGGS.containsKey(entityId)) {
            ItemStack spawnEgg = new ItemStack(Items.SPAWN_EGG);

            NBTTagCompound compound = spawnEgg.hasTagCompound() ? spawnEgg.getTagCompound() : new NBTTagCompound();
            NBTTagCompound tagCompound = new NBTTagCompound();
            tagCompound.setString("id", entityId);
            compound.setTag("AnimalTag", tagCompound);
            spawnEgg.setTagCompound(compound);

            playerIn.worldObj.removeEntity(target);
            InventoryUtils.dropItemStack(target.worldObj, target.getPosition(), spawnEgg);
        }

        return true;
    }

Please post code in a code block (the <> button in the editor) or on Gist/Pastebin with syntax highlighting.

 

That's not the same NBT structure created by ItemMonsterPlacer.applyEntityIdToItemStack, it uses "EntityTag" rather than "AnimalTag".

 

The target instanceof EntityMob condition is pointless, as it will always be false. When it's reached, target will always be an instance of EntityAnimal and can't be an instance of EntityMob.

Thanks. I finally got it to work but it doesn't work with other mods. Could you show me how to make it work with other mods?

It should work for any mob with a spawn egg registered, regardless of which mod it's from.

 

What makes you think it isn't working with other mods?

The Chickens mod doesn't use the vanilla spawn egg system for its entities, since they're all subtypes of a single class. It has its own spawn egg item.

 

You'll need to handle any mod that uses its own spawn eggs individually if you want your system to work with entities from those mods.
