Sure it can. But bear in mind that Java version '1.6.0_14' corresponds to JDK 6. As confusing as this might seem, in the Java world, "1.6.0" and "Java 6" are the same thing. Also, there's no reason why you shouldn't upgrade the version of Java on your system anyway - i.e. remove 1.6.0_14 (which is quite old now) and replace it with either 1.6.0_31 (aka "Java SE 6 update 31", aka "Java 6") or with 1.7.0_03 (aka "Java SE 7u3", aka "Java 7"). Your browser will use the newer version automatically once you've installed it.

thx danpost again - I owe you bigtime

I havent had a chance to check weather the sound works, but the image works perfectly! No spazing out and blinking, just one clean on and off. Thank you very much, I cited your work as a comment on the class.

That was my first thought, too... I was just hoping that there is an easier variable solution... But thank you for your reply! :)

Ok, thanks for letting me know. I'll rework the software for the next release so that it doesn't do that again in future.

Nevermind! I got it to work! Thanks so much for all your help! I really appreciate it!

Oh it working now! the program works fine with other computer!!!!!!!

Yep! It would let the world repaint, but it would still be an unbounded tight loop. See my comment above.

I would create an object inventory (an actor, but remove the extends Actor to make it an "other class") and inside of it make a static array called inv. You can make the array as large as you want inventory slots. Everything in this class must be static and can be called from another class by saying inventory.something or you can write inventory i = new inventory; i.something and not need to have statics. The advantage to the second method is that the variables will be reset with the program instead of having to write a reset method for it.

Not unless you're going to re-code the actual Greenfoot source-code

ok thanks i will give it a miss then :)

To have code execute only at the initial start of the scenario, create a method called 'public void started()' (a method of this name will over-ride the empty super-class method with the same name that is called when the 'Run' button is pressed. The only problem to deal with is, what happens when to scenario is paused and then re-started (it will run again). That being said, you need a boolean instance variable in the world class to track the initial start. <Code Omitted>Then, start your new method with

its ok i figured it out i just borrowed some pics

It had no tags on anyway - i have converted them in wavs anyway now - this was really irritating me!

Thanks! Works great... plus I understood the logic behind it! I'm gonna try and create a Game Over dialogue Box, which will appear when the Car.class no longer exists in the world. Will post feedback! Thanks again danpost!
