What does any of the code in the class have to do with a scoreboard? and why would you not place the codes to add objects into your world in your MyWorld class?

Unable to execute project after code change in portable version

Recompiling after code change does work: that's not the problem. The problem is that after all classes have been compiled after editing code, it is not possible to run the application from the main Greenfoot window: "Execute", "Pause" and "Reset" buttons are grayed (disabled) I've found a workaround: apprently Greenfoot configuration files that Greenfoot creates at first execution and modifies after configuration changes were corrupted. I had a 'greenfoot' folder into my personal folder, with files regularly updated by Greenfoot. I've deleted it and apprently everything works fine again no

Can you explain "return"? I though this was used to return something, an int or boolean.

The return command is used to cause an immediate break out of the method and "return" back to the method that called it. Once executed, no proceeding lines of code in that method are processed. In a void method, nothing will (or can) be returned. In a non-void method, only a value matching the return type will (or can) be returned. It is a control-flow type command similar to the break command (when void of a return type), which causes an immedi

Hey. I have another issue. When i embed the final code it will only run like 1/10 times. I can see the enter screen but it won't run. I read the other forum you had and it said that it should run automatically, but it's not. Any tips?

Show enter screen codes.

Game starts instantly when I hit enter before I press the "Run" button

<< Code Omitted >> but dialog1 doesn't disappear from the world

That is because dialog1 was never in the world. Again, you have "new Dialog1()" in your code more than once.

Thank you, I solved it by creating transparent pixels there and when intersecting, it moves back off it.

It is probably having each tube, both top and bottom, adding to the score. It would be okay to just allow it, internally. You can display half that value in the score display actor.

Sound Files

You have to place the sound file in the "sounds" folder of your project. If the file is called "a.wav", then you use "a.wav" and not the full path or anything complicated.
