thank you it worked

If you mean your world should be just a 3x3 grid you could just adjust this in the World-class: <Code Omitted> This means that your world is consisting of 3x3 cells, every cell is 200x200 pixels (so the width of your world actually is 600px - 3 cells a 200 px).. You can set your marks with something like <Code Omitted> This sets a mark into the middle cell, as you start counting cells with 0: 0/0 1/0 2/0 1/0 1/1 1

Use a boolean flag. Initialize it before, test while inside (changing its value if random is 1) and check its value after the while loop to do whatever when 1 hits.

now I need to make a score counter I have this so far. I don't know what else to do.

A simple breakdown of pong ball boundary codes would be like: <Code Omitted>

I solved the problem! I changed something in the counter class and it dident work anymore, so i copy and pasted everything in to a new scenario and it worked! But thank you for your response!

Add an act method to your World subclass (MyWorld) and go to end when no crabs are in world.

The tracks in my Tank Target Practice scenario are similar to what you want. The Track class codes may be something you might want to review. You can access them by logging in and playing (or just let yourself lose by letting 5 target appear and disappear without shooting at them); upon game over, a statistics screen will appear with code-viewing buttons along the bottom.

This looks like a problem in our MP3 library while it is trying to play that file. I would try converting the file to WAV in a program like Audacity, then see if using the WAV instead fixes the problem.

I will presume that nothing is ever assigned to tieenemy (that which is to be removed). At any rate, you can instead use the removeTouching method to remove that actor.

Post is lacking context, details and attempted codes.

thanks!! youre a genius ;D

i think i've figured it out
