Question

I am newbie to and-engine since working with it from fast two weeks. I am developing the ball game,My requirement as follows that when the ball touches to ground body for second time it should get destroy. I tried with update handler on ball sprite, its working fine when count reaches 2(I explicitly call remove logic).At the time it touches to ground body, I am destructing the ball body with the help of count in handler on Update(). Unfortunately for the first time also(count reaches 2 at first collision) body is getting destroyed. Above scenario is repeated often, worked with contact listener but no change.Any help would be appreciated.

@Override
public void onUpdate(float pSecondsElapsed) {
Shape path = new Rectangle(ballSprite.getX(),ballSprite.getY(), 10, 10);
if (ballCount <= 2) {
                mScene.attachChild(path);
                pathCoordinates.add(path);
                dumpPathCoordinates.add(path);
            }
            if (ballSprite.collidesWith(ground)) {
                ballCount++;
                if (ballSprite.collidesWith(ground) && ballCount == 2) {
                    removePath();
                    removeBall(ballSprite);
                    addFace(10, 10);
                }
            }
        }

Answer 1

Is it possible that the first touch lasts longer than one engine iteration? If so, you need to allow the ball removal only if this sequence occurs
touching->not touching->touching.
So far the ball is removed even if the sequence is
touching->still touching.
