Thanks! I got it working! The first opponent is now finished, and the game engine is 90% complete. Now for some visible progress :D!

Got it! I got rid of the direct link between distance and momentum. This is the working code:

Actually, it means that the parameters you are passing to the method are the wrong type(s), or that you have the wrong number of parameters. Check the documentation and make sure that you understand what you need to pass to it and that your code provides the correct parameters. (In your code, how many do you give? How many are required?) Similarly for line 11: Ball ball = (Ball) getOneIntersectingObject(this); What is the required parameter type? What are you actually passing? (check the documentation).

Nevermind, just realised that I have my if's in an ascending order, so it would always execute the last one last. I just made them "else if" and it worked :D. One problem though, when I set volumeLevel to 50, there's no audio? Here's the relevant code: In "Spikes.class"

Casting does indeed work for actors, as well as most classes. And that's good to hear about your class name :P

Thanks :D!

Possibly. Might be a project for the future :D. Thanks :D!

Yes, that is possible. Are you sure that's all you need to know? :)

hey davmac, BigDecimal num1 = new BigDecimal("1000000000000000000000000000000000"); this code really worked... thanks.. and thanks also to all those who replied... appreciate it.. but i have one more thing, how to ask for user input for two numbers? and how to check if the user input is using decimals or just integers.. -thanks

Ahhhhh! I get it, thanks :D.

It's updated now (bear in mind though that that's only temporary, a nicer page is on its way!)

Well, it works for me. Greenfoot won't magically change your code so if it moved in the diagram then you must have made it "extends World" again (instead of "extends wereld").

Please read this and post again.

Ok:;D
