Action RPG Framework

Hello, would anyone know how to make the abilitybar and abilitymenu change their icon_state every time a skill is on cooldown? I wanted that every time I use a spell, there's something visible in these HUDs showing that it's on cooldown. I've tried several things, but without much success.

I also tried to mess around with the player-abilities.dm. I did manage to achieve something at some point, but my code was too messy, so I gave up. I apologize if it's something simple, but I'm just out of ideas, haha
