I have looked everywhere including the Unity documentation but cannot seem to find any good examples of how to use Unity's Vector2.Reflect() function. I am trying to use this to control the direction of the ball (in a 2D Breakout game) when it hits a wall. It takes 2 arguments (inDirection, inNormal) but I cannot seem to figure out how to use this. Any help would be appreciated.
