I´ve created a crafting system and a little hotbar inventory. Now I need to create a real inventory.. I know how to create one, but I don´t know the right way to make it visible. I don´t wan´t to create an inventory that´s in a new layout, but on the same layout where my game is. So how could I setup an inventory on the game layout without having it on the screen while im playing? (To make it and the item´s in it appear by pressing a button or clicking an icon)
