I'm trying to register spawn eggs for some vanilla mobs that don't currently have them (specifically EnderDragons, IronGolems, WitherBosses and Snowmen).

 

I tried to re-register them with EntityRegistry#registerGlobalEntityID but I get an error saying that it was already registered. Plus, doing that seems like a bad idea to begin with.

 

Do I have to create a new item type for spawning them? Or can I just add standard eggs for them another way?

Sorr Iy only have the FML 1.8 environment on my pc so this *may* be different- but check the internal class EntityEggInfo.class in the EntityList.class. There's an addMapping() method that adds the entity egg to the list of possibilities with the egg color and such

I think its my java of the variables.

Thanks RANKSHANK that's what I had tried before, but you gave me another idea when you said that. You can't register something twice, but I went to look at the code where the entity gets registered. [embed=425,349]EntityRegistry.registerGlobalEntityID(Class <? extends Entity > entityClass, String entityName, int id, int backgroundEggColour, int foregroundEggColour)[/embed] actually calls [embed=425,349]EntityList.addMapping(Class p_75614_0_, String p_75614_1_, int p_75614_2_, int p_75614_3_, int p_75614_4_)[/embed]. That appends a value to a static ArrayList within [embed=425,349]EntityList[/embed] called [embed=425,349]entityEggs[/embed]. So, to add a new egg manually for an entity that already exists, I figured out you can do this:

 

[embed=425,349]net.minecraft.entity.EntityList.entityEggs.put(Integer.valueOf(63), new EntityList.EntityEggInfo(63, 1, 0));[/embed]

 

I'll leave this thread open for a bit in case someone else has a better way or a question. Thanks for the reply!
