unity3d 一个简单的飞行模式脚本(转自天涯老严博客)

以下代码未经测试，仅做研究，特别是后一段代码。
操作说明:

Q 向上移动

E 向下移动

按住左Shift 加速

W A S D 和默认的相同
在unity3d中替换Fpswalker文件即可
var speed = 6.0;

var jumpSpeed = 8.0;

var gravity = 0;

private var moveDirection = Vector3.zero;

private var grounded : boolean = false;

function FixedUpdate() {

my=moveDirection.y;

moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

moveDirection = transform.TransformDirection(moveDirection);
if (grounded) {
moveDirection *= speed;
} else {

moveDirection *= speed+transform.position.y/5;

moveDirection.y=my;

}

if(Input.GetKey ("e")) {

transform.Translate(0, -1, 0);

}
if (Input.GetKey ("q") ) {

transform.Translate(0, 1, 0);
}

if(Input.GetKey("left shift")) {

speed=6*5;

} else {

speed=6;

}

moveDirection.y -= gravity * Time.deltaTime;
var controller : CharacterController = GetComponent(CharacterController);

var flags = controller.Move(moveDirection * Time.deltaTime);

grounded = (flags & CollisionFlags.CollidedBelow) != 0;

}

@script RequireComponent(CharacterController)

private var myWalker: FPSWalker=null;

var maxHeight: float=250;

function Start () {

myWalker = gameObject.GetComponent(FPSWalker);

}
@script RequireComponent(FPSWalker)
下面另一个是我一牛B死党写的，更TMD的简练，半天我才搞懂。。
var sensitivity : float = .1;

var moveSpeed : float = 5;
function Update() {

transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * Time.deltaTime * sensitivity);

transform.Translate(Vector3.forward * Input.GetAxis("Vertical")* Time.deltaTime*moveSpeed ); //

transform.Translate(Vector3.right * Input.GetAxis("Horizontal") * Time.deltaTime* moveSpeed); //

transform.Translate(Vector3.up * Input.GetAxis("UpDown") * Time.deltaTime* moveSpeed);

}
别忘了还要到editproject settinginput 里面设置 UpDown

不错！!!!!!!!!!!!
