[1.11.2][Solved] Cannot cast from boolean to ItemStack


ModMCdl

Recommended Posts

Hey, I'm trying to set up my custom crafting tile entity, and I cannot find out why I'm getting this error: Cannot cast from boolean to ItemStack

	private boolean canCraft() {
		if(((ItemStack)this.inventory.get(0).isEmpty() || ((ItemStack)this.inventory.get(1).isEmpty()))) //this line errors
			return false;
		else {
			ItemStack result = PestleRecipe.instance().getPestleResult((ItemStack)this.inventory.get(0), (ItemStack)this.inventory.get(1));
			
			if(result.isEmpty())
				return false;
			else {
				ItemStack output = (ItemStack)this.inventory.get(3);
				
				if(output.isEmpty()) return true;
				if(!output.isItemEqual(result)) return false;
				int res = output.getCount() + result.getCount();
				return res <= getInventoryStackLimit() && res <= output.getMaxStackSize();
				
			}
					
		}

	}

Nothing else is broken, just this small bit.

 

Thanks

Follow these rules when talking to me, and we'll get along fine.

1).I know Java fairly well. I don't know as much about modding. They are not the same, don't compare them.

2). I consider myself to always be learning. I make mistakes, you make mistakes. Who doesn't?

3). Insult me, and I will leave the thread. I have a real life, I don't have time to throw petty insults in a Minecraft Modding forum.

(ItemStack)this.inventory.get(0).isEmpty() 

 

Well... you can cast a boolean to an ItemStack because a boolean isn't an ItemStack...

 

You probably wanted to cast the result ofinventory.get(0) to ItemStack, and check that ItemStack#isEmpty().

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Because isEmpty() returns a boolean. and then you are trying to cast that boolean to (ItemStack)

 

Wow. I can't believe I missed that. (Essentially, I guess I put my parenthesis in the wrong place lol). The fixed code looks like this to those who are having a similar issue.

	if(((ItemStack)this.inventory.get(0)).isEmpty() || ((ItemStack)this.inventory.get(1)).isEmpty())

And a boolean would be used to do this, as the solution above depicts.
