whew! ok. thank you very much!

if ( Greenfoot.isKeyDown("2")){ if (Greenfoot.isKeyDown("2")) isLooping = !isLooping; if (isLooping) { java.awt.Color a; int r = Greenfoot.getRandomNumber(255); int g = Greenfoot.getRandomNumber(255); int b = Greenfoot.getRandomNumber(255); int x = Greenfoot.getRandomNumber(this.getWidth()); int y = Greenfoot.getRandomNumber(this.getHeight()); int x1 = Greenfoot.getRandomNumber(this.getWidth()); int y1 =

You'd do well to follow the tutorials here: http://www.greenfoot.org/doc They'll take you through the interface for Greenfoot and start you off with some basic coding.

CrabWorld in this example is your class - you could create a thousand different CrabWorld objects as far as Java is concerned and that would be perfectly legitimate. A method like addObject() needs to be called on a specific instance of CrabWorld, which in this case is what getWorld() returns (the world that's currently active in the scenario.) If you call it on the CrabWorld class instead, the compiler has no way of knowing whether you want the method called on one world object, which world object, or whether you want it called on all the CrabWorld objects! From the compiler's perspective

You need to access the player object from the Healthbar object. Or the other way around. Either you make a method in Player that returns the health value, e.g. public int getHealth() { return health; } and then call player.getHealth() from your Healthbar object. But you have to work out how to access the player object (not the class) from your Healthbar object. Or you make a method in Healthbar: public void setValue(int value) { currentValue = value; } and call that method from player whenever the value changes. Again, you

Please don't share Greeps code and please don't ask for Greeps code. The Greeps scenario is used as a competition in classrooms. You are meant to experiment to figure out how to improve the Greep performance. It's fine to ask for help with other scenarios - but not Greeps.

Maybe call getWorld().konecIgre(someVariable) and have someVariable be the number?

Mine is telling me that it can't connect to its host. It might be because I'm on a school computer. We have everything fixed now and we're back on track. We've got all of our aliens working and everything else. We're currently trying to get the aliens to shoot back at us now. Thanks for all of your help though and be willing to help.

OK, the class doesn't extend actor, it's a completely new class, I added the Act() method myself under the assumption that it would be called automatically. I've changed it to updateSprites() and now call it from the World. Hi danpost, we decided on using a spriteFactory to represent our images so we would only have one instance of each image required for the game, then we reference that image in whatever actor requires it. Each sprite can have up to 11 images (currently) that increment every time act is called. without the spriteFactory we could be looking at loading up to 17 image

Yup. Just say something like <Code Omitted>

Nope :D. It looks good when it's rounded to pixels though, don't worry, as long as the precise coordinates are kept.

Haha, thanks! I'm gonna read through this again for any more copy-paste mistakes. So, advice to all: NEVER code when you're very tired :D! I did this yesterday after working a few hours on a model then doing my homework, bad idea :D.

You need to add a reference to TestWorld to prefix the call to explode(). 'reference.explode();'
