Not sure if this is the best way but the examples left tick running and that just keeps recalculating and in the case of FInterpTo it just gets exponentially smaller so I added a check that said when it was close to being open kill tick so it’s stops processing in the background all the time. Also set it up so it just adds 90deg to whatever the current Yaw is at the beginning of the game so it doesn’t matter how it’s rotated to start with.;
