well, you're not calling welle4, so it cannot increment AmountWaves to 4 or more, because the last time you can increment it is in Welle3(), where AmountWaves can only be incremented if it's value is equal to 2

AAAHHH Thank you so much that's so stupid, you can't imagine how long I tried to figure this out!!!

ok I've got the code to work now but there is a slight problem it only executes the action once I was wondering if it could be executed once everytime I press the button

That is what it should do. If not working properly, show your class codes.

Lines 17 thru 24 should not be in that act method. You are showing code to an anonymous Actor class that should be in another class. It is the act method of the outer class that those lines should be in.

When the game is over there comes a picture where you can read game over. Now i want to add a button on this page so that if you push it the game restarts. But how do i do it?

Is that a separate game over world or are you showing game over with an actor in your game world?

For some reason even though I changed the value of the isGameOver boolean to true, the method still keeps on running.

You changed the value of the isGameOver boolean in a world to true, but that would not be in the running world. You changed it in another world that you created on the previous line.

Remove line 2. Also, the getColorAt method does not work on a World object (it works on a GreenfootImage object) and requires two int parameters, not one.
