Hey again,
As far as I know, there's not a way to do this right now, but could we get consumable items? This would make it possible to have healing items, etc., which would be nice. You might have to put in an option to tell us if it's a healing item (restores health) or a buff (adds to defense/attack/movement for x length of time) or suchnot. It would be good to be able to interact with this in the script, too, so we could access custom properties.
Also, it would be cool if there was a way to design properties to an entity directly while editing it. This way, if I wanted to add a property to all entities of that type (let's say mana), I could do it without having to have a script to set it up. Kind of just a little housekeeping thing, but I thought I'd mention it lol. For that matter, it would be good to assign properties to the player specifically, and not just the entity accessed through the model page. That way if we want to do stuff like customize characters, the player's properties can remain the same.
Have a great day!
