On Trigger Collision/Overlap Stay

Hi, I need help with detecting stay on trigger volume. For example I have Box trigger volume in my scene and if my character enter in this volume I wont to perform some actions. I use OverLap Begin Event for actions fired when pawn enter the volume, but I also need actions for events when pawn is in that volume. For example trigger volume surrounding fire etc…

You want to set a boolean variable when they enter the volume and set it off when they leave it. Use a tick event or input event, use a branch and only perform the action if the boolean is true.
