GUI/Container slots [1.15.2]

[modders2 0]

I was wondering how to remove an item from a slot in my GUI.

I currently have 2 slots, and I want to, when the user clicks a button in the GUI, to remove it from the slot and then place a different item into the second slot.

 

I have the button setup like this currently in the Screen class:

@Override
protected void drawGuiContainerForegroundLayer(int mouseX, int mouseY) {
	super.drawGuiContainerForegroundLayer(mouseX, mouseY);
	this.font.drawString(this.title.getFormattedText(), 51.0f, 6.0f, 4210752);
	this.font.drawString(this.playerInventory.getDisplayName().getFormattedText(), 8.0f, 112.0f, 4210752);
	
	this.addButton(new ImageButton(this.guiLeft + 77, this.guiTop + 24, 21, 20, 0, 208, 21, BACKGROUND_TEXTURE, (e) ->  {
		System.out.println("Hello");
		
	}));
}

 

And the PlayerInventory, along with the two slots are initialised inside of the Container class  constructor here:

this.addSlot(new Slot(tileEntity, 0, 16, 26));
this.addSlot(new Slot(tileEntity, 1, 52, 26));

Buttons are client side. You will need to send a custom packet to the server, do the proper validations (check that the correct container is still open) and then modify the underlying inventory.

The fact that you are using your tileEntity variable as an inventory also suggests you are using IInventory, you should be using IItemHandler.

This tutorial project has two working examples of containers with GUI that you might perhaps find useful

Add the button to your ContainerScreen, and as dieSieben says, send a packet to the server when your button is clicked (if you don't know how, see mbe60 for clues) and forward it to your server-side container code to actually move the items.
