So my tile entity stores an entity, now what I want to do is spawn in a clone of that entity. This means that they don't share health or anything, but the clone starts of with the same stats as the original.

Nbt magic: Entity.createFromNbt(original.writeToNbt(new NBTTagCompound)) (<--pseudo code)

I could use NBT, but my entity is stored as an EntityLiving as I want to be able to store all kinds of mobs. My problem comes when I want to create a new entity, but I don't know exactly which one. If it was only a pig, for example, then I could create a new pig with

EntityPig pig = new EntityPig(worldObj);

but my entity could be anything from a cow, to a zombie, to a random mob from a different mod.

The entity that this gives me is null

EntityLiving e = (EntityLiving) EntityList.createEntityFromNBT(entity.getEntityData(), this.worldObj);

 

I did a check to see if 'e' was null, and it was

 

Well, you are using getEntityData... Nobody told you to. Read elix' post again.

 

writeToNBT returns a void

 

The only things that return an NBTTagCompound is

.getEntityData()

.func_174819_aU()

 

and neither of them would work.
