   def main

     loop do
      Graphics.update
      Input.update
      update
      if $scene != self
        break
      end
    end

Omg ty, did have to find it myself. Can you help me again?
For my system you get xp when you catch a fish, stored in an event variable. But, with this scene and a window, I show the lvls you have now. But the point is, as with every salmon you fish you get a random between 4 and 6 xp, you get after a while an insane ammount of exp... How can you make a formula to change the xp to a level? Thanks!
