How to change the [COLOR=#ff0000]direction[/COLOR] of the [COLOR=#ff0000]ball[/COLOR] when it hits the slanting line…
Like in mini golf game, the [COLOR=#ff0000]ball[/COLOR] should move in some [COLOR=#ff0000]direction[/COLOR] when it hits the wall…
i did it, but it works well for rectangle like shape,
but for diagonal its not working ie. the [COLOR=#ff0000]ball[/COLOR] goes away in one [COLOR=#ff0000]direction[/COLOR]…
i need to change the [COLOR=#ff0000]ball[/COLOR] [COLOR=#ff0000]direction[/COLOR] randomly but it should not go away from the wall…
