ability help

[retrogamer97]

Hey guys, I am trying to add a dead eye feature to my mod inspired off of red dead redemotion. The code to freeze time works but anyones of a existing mod that lets you activate an ability then turn it off whenever you want to? I dont want to use the ability then just go away after x tics.

Off the top of my head, you can just make a powerup with an infinite duration and give and take away as necessary.
