Well, if you want some suggestions on your code, you’ll get more responses if you post the relevant code in the forum with code tags: Using code tags properly
Just going off your description, I’d say you want to “not loop” if you’re successful, and display the end level or level complete screen. I’m sure you could google for many examples of an end of level script.
Try to work it out, and if you have a specific issue, then you should post with the details, code, and what you’re hoping will happen.
Maybe you want to not loop and show a graphic, or panel + graphic + text at the end?
Maybe you want to change scenes to a different scene to show something or start a new level - I don’t know…
