nccb: Thanks a lot! I've been very busy so I'm just reading your post - thanks again!!! - and I might take a while to check your directions, but I'll tell you what I get by trying, and some actions I've already run by myself. I'll keep in touch. P. S.: Did I already say thanks?

Tell yourself exactly what you want the actor to do, and half the code is already there. Say: If see food, eat food. if ate foot, migrate home. if home, wait2seconds. if none of the above, move around. What do we have?<Code Omitted>I used two instance va

Try this: <Code Omitted>

So have you declared frameNum or frame as your counter? (you didn't show the declaration)

Yeah, but only 1 rock at a time. Here's the finished project (modified to more of a space-like thing). Click here for game

Yep that was the problem, I knew it was something small and easy. I really appreciate it. Now if I can only figure out what's wrong with my output for the character and why Greenfoot.playsound is not working.

There really shouldn't be a difference - I don't understand why the second version of MainMenu would work if the first one didn't. If you upload the entire scenario I'll have a look.

ahhh, thats what i wanted. Thanks!!

Thanks that solves it. Is there a way to empty data at a specific index from an array? Thanks again. This is hugely helpful.

Actually, I got help from my professor today and she suggested that I adding this to my code and it worked: Constructor: this.xCoordinate= new int; this.yCoordinate= new int ; method array: { int currentX = getX( ); this.xCoordinate = currentX + Greenfoot.getRandomNumber (550-currentX); this.xCoordinate = currentX + Greenfoot.getRandomNumber (550-currentX); this.xCoordinate = currentX + Greenfoot.getRandomNumber (550-currentX); this.xCoordinate = currentX + Greenfoot.getRandomNumber (550-currentX); this.xCoordinate = currentX + Greenfoot.getRandomNumber (550

The easiest way to solve this is to look for a click on the arrow instead of the chess. By the way, this also allows movement to square without a chess on it. If you just wanted to select a different chess and show arrows around it, you could have it so if you click anywhere except on an arrow, the arrows are removed, and if that click was on a different chess, show the arrows around it (if the click was not on a chess, no arrows will be present, and you can then click on any chess).

Use two sets of square brackets instead of one private int coords = { { x1, y1 } { x2, y2 } { x3, y3 } ... }

To achieve the following: if clicked and not flipped, flip; if clicked and flipped, select; and if selected and keystroke found, move; Use the following:
