How to Undo Collision Effects

I meant to say earlier that I wasn’t sure about using integer variables in this project because the Lifetime integer acted like a timer, meaning the power would be lost after the Lifetime number reaches 0. I figured this out after playtesting and examining the BP for each actor. I blame frustration and fatigue for not expressing myself better, last night. That was why I considered a Boolean variable, so I could set those variables to “true” or “false.” How would an integer variable work in the same scenario?
