You can achieve that with the method I showed you… In you character blueprints on event begin play you will set timer by function name. The function name you will be using is a function that adds 1 to your variable which is your seconds. Your variable is what the widget will say for example if your variable is 25 then your widget will say 25. Now when you overlap a box collision in your character blueprint you will “Clear timer by function name” The function you will be using is your seconds function that adds 1 to your variable. So when the function stops then your timer will stop and leave your variable alone and your widget alone.
