GUI where you can only place certain items

Started by RexCerv on Mon, 08/02/2021 - 17:33

So I wanted to make a GUI and for testing, I made only 1 slot, in this slot I wanted to know if it's possible to specify only to accept certain items, so I first added a random block in the specification and then going to the code and deleting it, then I tried adding the stuff I want to specify where the random block was (and yes I did Import all of the items and delete completely the other block). And because it didn't work, I was wondering if there's a way to do it with procedures or just coding, maybe I did it wrong. By the way, I'm in 2021.1, Minecraft Version 1.16.

(If anyone didn't understand what I meant, here's an example: Imagine I want to only be able to put Gold, Diamond, Iron, Coal, etc on 1 slot, but I can't put other items like dirt or other things. And yes MCreator does let me specify items per slot, but it only lets me specify 1 item, when I want to specify at least 10.)

That will take a lot of procedures I recommend trying a tutorial from Mod monster or cursed warrior

In the workspace right click your GUI and select "lock/unlock mod element", then double click and open the GUIMenu.java, search for the custom slots, it should look like this (I'll use the minecraft arrow for example):

this.customSlots.put(0, this.addSlot(new SlotItemHandler(internal, 0, 44, 31) {
    @Override
    public boolean mayPlace(ItemStack stack) {
        return (Items.ARROW == stack.getItem());
    }
}));

Now what you need to do is add the items you want:

this.customSlots.put(0, this.addSlot(new SlotItemHandler(internal, 0, 44, 31) {
    @Override
    public boolean mayPlace(ItemStack stack) {
       return (Items.ARROW == stack.getItem() || ProjectLkModItems.SARTORIUM_ARROW.get() == stack.getItem() || Items.SPECTRAL_ARROW == stack.getItem() || Items.TIPPED_ARROW == stack.getItem());
    }
}));

You just need to add || between them, to get the vanilla items hold left control + left click on Items in "return (Items.ARROW" MCreator should open the items list, after all that press control + W so the code can fix and get the right imports, now just save the code and be happy.
