I am trying to make an item spawn my mob, but I don't understand how to do it. I thought this method would do it but for some reason this doesn't work, nothing spawns:

 

	@Override
public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) {

	if(!world.isRemote) world.spawnEntityInWorld(new EntityBlockling(world, level, xp, upgrade, special));

        return itemStack;
        
    }

 

I looked in the normal spawn egg code but couldn't figure it out.

How do I do that though, as the parameters don't contain an x, y, or z coordinate.

You are spawning your mob on a really strange place,

your x coord = special

your y coord = xp

your z coord = upgrade,

 

Use things like player.posX instead of random numbers like xp.
