背景

有同学问我,如何设置方向键和wasd控制2个不同角色呢？

步骤

打开设置面板

Edit->Project Settings->Input，你可以看到下面的界面

知识点：

这个一个数组结构，所以图里【axes】下一共是15项，每一项通过一个名字设置一个按键的属性，比如我们常用的[Horizontal]。
[Horizontal]可以在代码中调用，就像这样

value = Input.GetAxis ("Horizontal");

那么属性里面这两个很重要

确保在默认设置中，删除了wasd的控制

更改数组下方另外一套按键设置，改名字和按键。这样你就可以通过Horizontal2来获取player2的输入

这里是其它按键的名字

Joystick Buttons (from any joystick): “joystick button 0”, “joystick button 1”, “joystick button 2”, …
