When my end screen pops up I want the everything in the game to stop running or even just destroy other actors. Like currently if my player dies I have a pawn that functions like a turret and it just keeps firing even when the player is dead and the end screen comes up.
You could add a Boolean variable and call it like game over,when you create the end screen widget,just set it to true.
Then in every your turret before do anything first check the variable.
Only when the game isn’t over can do anything.
