Custom Gui functions like its linked to the players inventory, while it is not.

[gwoonryan]

Hi, I am trying to get custom GUIs working, and I would like to have a GUI that works only client-side, which means that you are not supposed to pull items out, but I do want to display items in my GUI and let the player click them.

I have a GUI working that has a size of 54 slots and I made a custom texture to remove the player inventory from the GUI texture (see image)
Everything kinda works, but is seems like the inventory is in some way still linked to the player's inventory, even though I didn't add any slots linked to the player's inventory.

As an example: If is click in the 5th row of my GUI, I get the chest that was in my hot bar slot (see image).

It seems like the handling of the clicking of the inventory is handled by the player inventory still. I also get an error if I click in the bottom row because "java.lang.IndexOutOfBoundsException: Index: 49, Size: 45" the player inventory has a size of 45 I guess?

I have posted all my relevant code below, if more is needed to solve this issue please tell me, thanks!

FlipsMenu.java: Opens the menu by changing a "screen to open" variable that gets checked every tick.

private static void openMenu(String serverResp){
		// some code to read "serverResp"
  		ConfigManager.screenToOpen = new AHFlipsGUI(new AHFlipsInventory("Best Flips", 54));
  }


// code in the tick event: (not in this class)

if (screenToOpen != null) {
    Minecraft.getMinecraft().displayGuiScreen(screenToOpen);
	screenToOpen = null;
}

 

AHFlipsGui.java: draws the background image and specifies size of the gui.

        this.inventory = inventory;
