本文转自其它网站。添加了First Person Controller后，直接挂上代码即可实现跑步与下蹲。下面是相应的JavaScript代码：
var walkSpeed: float = 7; // regular speedvar crchSpeed: float = 3; // crouching speedvar runSpeed: float = 20; // run speedprivate var chMotor: CharacterMotor;private var ch: CharacterController;private var tr: Transform;private var height: float; // initial heightfunction Start(){ chMotor = GetComponent(CharacterMotor); tr = transform; ch = GetComponent(CharacterController); height = ch.height;}function Update(){ var h = height; var speed = walkSpeed; if (ch.isGrounded && Input.GetKey("left shift") || Input.GetKey("right shift")){ speed = runSpeed; } if (Input.GetKey("c")){ // press C to crouch h = 0.5 * height; speed = crchSpeed; // slow down when crouching } chMotor.movement.maxForwardSpeed = speed; // set max speed var lastHeight = ch.height; // crouch/stand up smoothly ch.height = Mathf.Lerp(ch.height, h, 5*Time.deltaTime); tr.position.y += (ch.height-lastHeight)/2; // fix vertical position}
