I know you can add a tooltip using the control, but I have a inventory and it has different items. I don't think it would be practical to add 50 control nodes one for each slot but correct me if I am wrong. I want it so that if you hover over a slot it shows the stats for the item similar to Terraria's inventory tooltip system. Not sure how to do this.
Note: This same problem was asked by me here, just trying to see if I can reach more people.
Godot's ItemList is well suited for an inventory system with many slots, and it provides a set_item_tooltip function to add tooltips for individual items.
