You may want to check out the java tutorials starting with the page on Classes. Of particular interest, might the the page called Understanding Class Members.

@davmac the problem is I'm stupid and I need to set a flag at the tomato so one greep stays there while he helps the rest load the tomato onto their backs. I don't know how to do this..

Before trying to explain what an array of Tile objects (see line 4 of the Tiles class) is, let us start with something a little more basic (since you know what int and boolean are). An array is used to essentially store in memory more than one value (usually) using the same field name. The values stored are indexed (starting at zero) so that any value (or element) within the array can be directly accessed. These elements can be of one of the primitive types (int, double, boolean, char, etc.) or of a reference type (String, Font, Color, Tile, etc). Once an array is created, its size is im

You will be getting a List object from the return of 'getIntersectingObjects', at any rate. However, you could determine the count this way: <Code Omitted>where the final count will be two plus the number of objects that actually interfere with the line of sight. If you have other objects that should not be considered as ones that interfere wi

Thank you for the help! That solves my problem!

Hey I got it down. I used a firing method similar to that of Greenfoot Space Invaders. From there I used the animal class to make the shell eat the bomb then a destroy command.

Thx so much danpost! you really help a lot. i finished my game now thx to you.

Like I said, I had to totally re-write those classes; I ended up with this for the super world class ('ModWorld' is now named 'FullScreen'):

Never mind, I had some help and it's done now, thanks to anyone reading this.

Compare lines 3 and 4 of both code posts. The second set of lines has access modifiers and either a type or a name (I cannot be sure which); but the lines are missing one of them.

Oh, wow, you were right. The music was unnecessary anyways, so I just removed it -- cleared an amazing amount of room, and was able to be published. Thank you!

Where did you get the 'canMove' method? what is its code? The Actor class provided by greenfoot does not contain a 'canMove' method. Without seeing it code, it is impossible to say what it does or what it will do in any situation. The only other thing we could do is maybe suggest that you just test it out yourself to see what it does.

Thanks so much!

http://www.greenfoot.org/support Try this page- it usually fixes all the problems you might have. If you're using an .msi file, make sure your operating system is windows (preferably 7 or later). Redownloading Greenfoot also fixes most situations. If the problem still incures, post your OS, JDK version, Greenfoot version, and all other error messages.

When you say that the image of the hero is the image of the background when camouflaged, do you mean that the hero is essentially invisible? Line 11 checks to see if the 'camoHero' image is set as the image of the villain. Is that really what you want to check? And, in either case, the images will not be the same unless 'camoHero', specifically, is set as the image (creating a new image from the file "space.jpg" file will never be "the same image" as one already created and set (they are two distinct object and one is not the other and comparing them with '==' will always return a false v
