changing worlds by choices

If you want either of the passed objects to trigger the if statement, you can use <Code Omitted>

But, that is not what is wanted. That is, not one or the other choice is to be made, but both. To achieve that, neither choosing can trigger the problem world. A separate button actor should be used for that. One of each set of choices can be pre-selected and the user can change the selection at will. When satisfied, the user can click the "Done" or "Proceed" (or whatever) button.

End of Greenfoot?

Don't worry, java will still be developed, and for a long time, the only thing that won't be developed anymore is Java SE 8. While Greenfoot works (I believe) with java 8, there are many possibilities : 1. Greenfoot will switch to a newer java version 2. Greenfoot won't switch, but it won't affect us, because extended security updates will still happen til 2030

I'm pretty sure there is a problem with line 22. ... Try to replace it with << Code Omitted >>

Same thing. No problem there.

rocket770 wrote...

Also, the reason the code is not compiling is that in line 5, you declare a variable named "lines" and you do the exact same in line 24. Try changing the name to something else.

Yes. That is the current problem -- trying to declare another variable with the same name as one already declared.

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!!!
