I will try to find some information about that.
Sure, if you run the sample, it should happen there as well. What happens is, the ball actually will "sometimes" stick to the wall that it is hitting, and then "sometimes" bounces like you would expect and "sometimes" it actually gets stuck in the wall it is touching and will start to vibrate or "tunnel" through the wall.
This could be addressed by resetting the position of the sprite based, but, I'm just trying to write the samples as shown in the AndEngine samples, and there appears no need to do that in those samples.
In the AndEngine code, it handles the check for the moving ball in here:
B4X:
private static class Ball extends AnimatedSprite {
private final PhysicsHandler mPhysicsHandler;
public Ball(final float pX, final float pY, final TiledTextureRegion pTextureRegion, final VertexBufferObjectManager pVertexBufferObjectManager) {
super(pX, pY, pTextureRegion, pVertexBufferObjectManager);
this.mPhysicsHandler = new PhysicsHandler(this);
this.registerUpdateHandler(this.mPhysicsHandler);
this.mPhysicsHandler.setVelocity(MovingBallExample.DEMO_VELOCITY, MovingBallExample.DEMO_VELOCITY);
}
@Override
protected void onManagedUpdate(final float pSecondsElapsed) {
if(this.mX < 0) {
this.mPhysicsHandler.setVelocityX(MovingBallExample.DEMO_VELOCITY);
} else if(this.mX + this.getWidth() > MovingBallExample.CAMERA_WIDTH) {
this.mPhysicsHandler.setVelocityX(-MovingBallExample.DEMO_VELOCITY);
}
if(this.mY < 0) {
this.mPhysicsHandler.setVelocityY(MovingBallExample.DEMO_VELOCITY);
} else if(this.mY + this.getHeight() > MovingBallExample.CAMERA_HEIGHT) {
this.mPhysicsHandler.setVelocityY(-MovingBallExample.DEMO_VELOCITY);
}
super.onManagedUpdate(pSecondsElapsed);
}
}
}So think you would need to expose the onManagedUpdate (which is what it looks like the PhysicsHandler Update should be)
That I understand, but I do not have any sprites loaded when I have tried getting the Scene_AreaTouched to fire.
I have never been able to get it to fire, even if only the scene is loaded and the listener is set.
However, if I set Scene.setOnAreaTouchListener, (and not the Scene.setOnSceneTouchListener), the SceneTouched Event is fired, which I don't think is what you are looking for to happen.
My error log is posted above for my S3, as I said, the SL does not give an error... it just quits and resets... D'oh!
