Message Being Sent Twice


Recommended Posts



I am made an item that uses a random number generator to generate a number, then to test it I made it send a chat message to the player. However, when the item is used, it sends two chat messages, meaning it is generating two numbers. I want it to only generate one; could someone help me?


public class QuirkGiver extends ItemBase 

	public QuirkGiver(String name)
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn)
		ItemStack itemstack = playerIn.getHeldItem(handIn);
		if (!playerIn.capabilities.isCreativeMode);
		int number = ((int) (Math.random()*100))+1;
		playerIn.sendMessage(new TextComponentString("you got " + number));
		 return new ActionResult<ItemStack>(EnumActionResult.SUCCESS, itemstack);

This happens because Item#onItemRightClick is executed once for each side - once for client, once for server. You need to check for the side you are on before doing actions.


As a sidenote:

ItemBase is an antipattern. There is already an ItemBase, it's called Item.
