Unity-如何使用Vector2.Reflect() [英] Unity - how to use Vector2.Reflect()

问题描述

我到处都看过，包括Unity文档，但似乎找不到如何使用Unity的Vector2.Reflect()函数的任何好例子.我试图用它来控制球碰到墙壁时的方向(在2D Breakout游戏中).它需要2个参数(inDirection，inNormal)，但是我似乎无法弄清楚如何使用它.任何帮助将不胜感激.

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.

推荐答案

Vector2 Reflect(Vector2 inDirection, Vector2 inNormal):

inDirection:黑色箭头

inNormal:红色箭头

return output:绿色箭头
