Zamoht... thanks!!!

Look up "for" loops and "while" loops. Also, Greenfoot. has the methods "getWidth()", "getHeight()", and "getWorld()".You can use them to find out when to go to the next colomn/row. I can't just give you the code though; you wouldn't learn really anything. I can tell you that it will involve a nested loop though.

or just use: <Code Omitted>

Conor_Begley: Could you post a link to the scenario, wherever you've uploaded it?

I think this might help you!!!

You mean 'where should I move the calling of 'atWorldEdge' to in the Seagull and Seagull2 classes?'. The act method of those two classes should have the code to remove them if 'atWorldEdge'. <Code Omitted>

No. 'Animal' is a class, not something that can be at the edge of your world. You need an Animal object; an instance of the Animal class; an actor created from the Animal class or a subclass of Animal. <Code Omitted>You need a specific animal object. But, since you will be calling 'atWorldEdge' from your Seagull and Seagull2 classes, the point here is moot.

thank you thank you thank you!!

Sounds like you need to look over the first three section (skip over what you are already familiar with) of the Java tutorials. What I suggested above was fairly basic and if you are having trouble understanding it, you should review those sections.

First, create the bullet or shot class (whatever you want to call the projectile that the turret will be shooting out). Then, create a simple 'fire' method in the class of the turret to create a projectile. Then implement a timer to regulate the launching of the projectiles. After that, you can ask about finding targets in range to fire at.

First off, it is not wise to name your variables with the same name as the class (especially if you are going to ask if the value of that variable is null). So, before anything else, rename 'goku' to anything else (maybe 'gokuActor' or 'gokuObject') and similar with 'gokucharge'. The only other thing I can immediately see, is your last line of code that gets a 'gokucharge' object does not do anything (you are assigning a local variable to an object (if it is not 'null') and then not doing anything else with it.

ScrollActor and ScrollWorld by SPower can be found here: ScrollWorld

You named the method incorrectly on line 19.

For an example, I uploaded a demo for your benefit. You can view the code while running the scenario.
