Returning multiple ItemStacks

[Lambda]

Hello,

 

So, I'm needing to return multiple itemstacks for when 2 items are equal, however, I'm having trouble doing this..

 

Here is what I have currently:

    public ItemStack getResult(ItemStack input) {
        for(CrusherRecipeHandler recipe : crusherList) {
            if(ItemUtil.areItemsEqual(recipe.input, input, true)) {
                return ;
            }
        }
    }

I need to return

recipe.output and recipe.outputChance

Both of which are itemstacks. Using ItemStack[] doesnt seem to work, as it returns mutiple of ONE itemstack.

 

Thanks.

list = new ArrayList<ItemStack>()

...

list.add(recipe.output);

If you own the getResult method, you can change it yourself to return an ItemStack[] or a List<ItemStack> and update the usages of the method accordingly.

So something like this?

 

    public List<ItemStack> getResult(ItemStack input) {
        for(CrusherRecipeHandler recipe : crusherList) {
            if(ItemUtil.areItemsEqual(recipe.input, input, true)) {
                ArrayList list = new ArrayList();
                list.add(recipe.output);
                list.add(recipe.outputChance);
                return list;
            }
        }
        return null
    }

Well....recipe.outputChance isn't an ItemStack, so no....

Yes, it is.

okay, so know when trying to validate the slot for input, I'm having issues setting the itemStack to the list that getResult() will take:

    @Override
    public boolean isItemValidForSlot(int i, ItemStack stack){
        return (i==SLOT_INPUT_1) && StackUtil.isValid(CrusherRecipes.instance().getResult(stack)); //Cannot return just an ItemStack, must be a list
    }

 

Trying to set the parameter to List<ItemStack> doesn't seem to work correctly.

If your getResult is a list, then you need to iterate over it and check ALL of its contents and validate each one individually.
