Hey there,

for solving this kind of issue it might be helpfull for you to get a bit into Logging messages. For example to log what value you actually have in your “LevelChange” variable when you try to load the next scene. You will notice that it always will have the value 1.

This happens because your player Instance get’s created new in each Loaded Scene. There you call the Startfunction and set the LevelNo and LevelChange variables to 0. Thus you can never escape loading the second Level again and again.

You should be able to fix your problem by changing the following things:

  • Remove the Line where you initially set LevelChange to 0 in the Start() function.
  • Change the LevelChange variable to private static int LevelChange
  • actually increment the variables Value. So instead of LevelChange = LevelNo +1; have it say LevelChange += 1;

This way your LevelCounter’s value should be preserved even when loading a new scene.
Hope this helps/works.
