Because I originally could not get the drivers to load, I used alternative software versions from the official OpenNi sites, and this seems to have caused the issue, as I followed your suggestion and reinstalled the versions from the Greenfoot site and it now works. Thanks. I managed to solve the original driver problem by installing them manually through the "Add hardware" program in Control Panel. If I didn't do that, the drivers failed to automatically install and there was nothing in the Device Driver panel to show any Primesense devices. I'm suprised this hasn't been a problem for othe

It kinda does return the specific type of enemy in a way. It will return the specific type of enemy object at runtime alright, but the compilor doesn't know what subclass of enemy it's going to get when it compiles the program, hence it will only let you use methods that are defined in the enemy superclass in your code, unless you cast it to a more specific type, and you should only do that if you have a situation where you know for sure what kind of enemy you are going to get, otherwise I believe it causes a run time error. That aside, at runtime java will know which subclass it has though, a

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:

Please read this & post again.

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.
