You can just change the '8's to 'getWorld().getWidth() - 1' or 'getWorld().getHeight() - 1' (depending) and it will work for any size board. I checked up on 'Go (board game)' on Wikipedia. The corners are safe and the edges are fairly safe; so, what I had prior to the most recent code post was more to the rules of the game. That is, for lines 19 through 22 above, you would use:

import java.util.List; public int pointTo(int x, int y) { int dX = x - getX();//get distance between mouse's X and player's X int dY = y - getY();//get distance between mouse's Y and player's Y double rotation = Math.atan2(dY, dX); rotation = Math.toDegrees(rotation); return (int)rotation; } List<Worm> crab = getObjectsInRange( 2000,Worm.class); if(crab.size()!=0){ pointAtObject(crab.get(0)); move(6.0);}

No. That is not possible. Although, you could create a public method that will except a keystroke and store it for future use, if that is what you want. Why would you want to 'pause' the execution of the scenario and still allow keystrokes to be directed to it? Maybe(?) you did not explain what you wanted clearly enough and there IS(?) a way to do what you want.

Ok it is running =) thank you - But there is still an other problem: When I want the snake to jump and I push the "jump key" two or more times while the snake is jumping for the first time, it also will jump two or more times after landing - also when I don´t push the "jump key".

thanks! I did what you said and it now works. changed the getOneIntersectingObject method to the getOneObjectAtOffset method.

To answer your first question: You could use turnTowards and then turn(90). You would always move at a tangent...

A similar thing (changing the image by rotating through a set of different images) is explained in the Joy Of Code, Episode 17 (towards the end). However, there it uses an if-statement instead of the modulo operator (%). The modulo operator is a little more elegant, using an if statement is (initially) easier to understand. The bit about changing images starts around 16:40.

I agree with Morran. I like the interface of Gimp but learning to navigate through it can be hassle.

Greenfoot is very easy to learn. It is a good application. It is used by people learning computer programming. It is also used to make serious games. For example, Biomechanoid Chicken, Nightmare: Emergence, and RockSmash. Look around this website to see what Greenfoot can do.

The possibilities are endless! (I always wanted to say that)

i think that makes sense... i have seen this enacted in the program i made. So this does make some sense.

Your Ball class only accepts one Counter for each Ball created. You gave one Ball 2 Counters in your PongWorld. Unless you want to have two different Balls for each Counter, you need to have your Ball class accept 2 Counters. It's not too hard, maybe something like this:

Hey again, must say thanks for your help, but I have one final question. On the final level, I want the timer to stop and display the time as soon as the Actor reaches the world so I would have text in the background that says -------- Your Time: # (the # being the final time) How do i display a stopped final time as soon as it reaches the level?
