学这个。。 var target : Transform;
var xSpeed = 250.0;
var ySpeed = 120.0;

var yMinLimit = -20;
var yMaxLimit = 80;

var initDis = 20;
var minDis = 3.0;
var maxDis = 50.0;

var wheelSpeed = 5;

static var x = 0.0;
static var y = 0.0;

static var distance;

private var position;
private var rotation;

function Start () {

x = 130;
y = 30;

transform.rotation = Quaternion.Euler(y, x, 0);;
transform.position = Quaternion.Euler(y, x, 0) * Vector3(0.0, 0.0, -initDis) +
target.position;

// Make the rigid body not change rotation
if (rigidbody)
rigidbody.freezeRotation = true;

}

function Update () {
if (target) {
distance = Vector3.Distance(target.position,transform.position);
if(Input.GetMouseButton(1)){
x += Input.GetAxis("Mouse X") * xSpeed * 0.02;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;

y = ClampAngle(y, yMinLimit, yMaxLimit);
}

distance-= Input.GetAxis("Mouse ScrollWheel")*wheelSpeed;//获取鼠标中建响应
distance = Mathf.Clamp(distance,minDis,maxDis);//距离取最大值和最小值

rotation = Quaternion.Euler(y, x, 0);
position = rotation * Vector3(0.0, 0.0, -distance) + target.position;

transform.rotation = rotation;
transform.position = position;

}
}

static function ClampAngle (angle : float, min : float, max : float) {
if (angle < -360)
angle += 360;
if (angle > 360)
angle -= 360;
return Mathf.Clamp (angle, min, max);
}

如果你还有什么不懂的，可以百度搜下：编程回忆录，他们现在正在录制这方面的教程，都是零基础开始，由浅入深。追问

有代码也不懂得用
