I am making a maze game and I am having trouble getting my ball to stop and not go through the wall when it hits it. Here is my attempted code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 | public class Ball extends Animal{ private boolean moving = false; /** * Act - do whatever the Ball wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { checkKeypress(); } public void checkKeypress() { int x = 3; moving = false; if(moving = false) { if (Greenfoot.isKeyDown("left")) { move(-x); turn(-5); } setRotation(360); if (Greenfoot.isKeyDown("right")) { move(x); turn(5); } setRotation(90); if (Greenfoot.isKeyDown("up")) { move(-x); } if (Greenfoot.isKeyDown("down")) { move(x); } setRotation(0); } if(canSee(HWall.class)) { moving = true; } if(!canSee(HWall.class)) { moving = false; } if(canSee(VWall.class)) { moving = true; } if(!canSee(VWall.class)) { moving = false; } if (moving = true) { x = x*(-1); } }} |
