What?? I thought you were talking about the avatar game logic that can be turned on or off with a game logic event (looks like a gear)!
I can (try to) explain what you're talking about. Run Logic in Start means that certain events will happen before you actually start the level. Ex: If you have a Cut Here event that doesn't require a signal and RLiS is off, the camera will only cut once you tap the screen. But if RLiS is on, the camera will already preform that event before you tap the screen. Like Cube said, it's difficult to explain, and I hope this helped you. But I'm just sayin'. EDIT: That's the one I'm talking about.
1st picture : . Clone Shap is just to say if your level start with Clony or Cuby 2nd picture : . Enable/Disable avatar game logic can desactive the flying mode : when player click on the screen nothing happen
Avatar game logic can reset also all powerups effect -> Clony become in his normal size without any special aspect
