I'm trying to nerf my rolling system since at the moment, you can roll forever at with no penalties. If a weapon swing makes you hit 0 stamina, you get a cooldown penalty where stamina doesn't regen and that works fine, but if rolling causes it then stamina keeps regening normaly even if you hit 0.
I just want it so if you hit 0, you get slapped with a 3 second cooldown that you don't regen stamina for that duration.
Another thing is how do I make the player not be able to attack during the roll?
