Hey, I'm doing a game where you need to race other AI on a track but I don't know the code for the AI to move around the track without hitting the walls on purpose. Can anyone help?

Easy configurable method for random movement:
?

public void moveRandomly(){
      move(7);
      if (Greenfoot.getRandomNumber(100) < 10){
          turn(Greenfoot.getRandomNumber(90) -45);
      }
      if (getY() < 20 || getY() > 378 || getX() > 590 || getX() < 20){
          turn(180);
      }
  }
For the killing method u could just use the removeTouching(urProtagonist.class); method or write a more complicated, but more interesting function. U could do a collisioncheck inside ur protagonist too. Here is an example:
?

8
public boolean collision(){
    if(whateverUrConditionsAre || this.isTouching(Enemy.class)){
        return true;
    }
    else{
        return false;
    }
}
and then let ur protagonist call a die-function in wich he dies dramatically :P

@FairerFish: Make a new thread..:) BTW: you have to program a pathfinding algo like the A*algo( can be found at Wikipedia) or let the AI follow a Array of positions u set up. Both ways are not too easy to implement i know.
