Action RPG Inventory System

If you don’t mind. All I want is that you can drag items like potions and food and such into the hotbar and use the numbers keys to use the corresponding slot. As for now, I can’t drag Items from and to the inventory nor equipment panel but can drag from the container into the inventory and equipment panel. I know it was possible before I fixed that issue with the inventory slots being all white so you couldn’t see the icons. After I fixed that according to this forum, dragging and right clicking in the equipment panel to unequip stopped working. And I fixed my issue that the inventory stopped being displayed. Turned out it was the equipment panel which I extended to 20 slots that caused the problem.
