Hi,

 

I am trying to spawn an entity on the right click of an item with this code:

@Override
public ItemStack onItemRightClick(ItemStack item, World world, EntityPlayer player) 
{
	if(!world.isRemote)
	{
		Entity entity = new EntityZombie(Minecraft.getMinecraft().theWorld);
		entity.setPosition(player.posX, player.posY, player.posZ);
		world.spawnEntityInWorld(entity);
	}
	return item;

}

 

and then when the entity spawns it just stands there and does nothing. I have also tried going into survival, pushing it around and even trying to hit it but it doesnt work.

Why are you using

Minecraft.getMinecraft().theWorld

?  This is both client side only and unnecessary as a world object was passed to the method already:

onItemRightClick(ItemStack item, World world, EntityPlayer player)
