How to change the direction of the ball when it hits the slanting line…
Like in mini golf game, the ball should move in some direction when it hits the wall…
i did it, but it works well for rectangle like shape,
but for diagonal its not working ie. the ball goes away in one direction…
i need to change the ball direction randomly but it should not go away from the wall…
