如何使用Unity进行360度观察物体？ - 纳金网

var target:Transform;
var distance = 10.0;
var xSpeed = 250.0;
var ySpeed = 120.0;
var yMinLimit = -20;
var yMaxLimit = 80;
var distanceMin = 3;
var distanceMax = 15;
var x = 0.0;
var y = 0.0;
//@script AddComponentMenu("Camera-Control/Mouse Orbit");
function Start () {
var angles = transform.eulerAngles;
x = angles.y;
y = angles.x;
// Make the rigid body not change rotation
if (rigidbody)
rigidbody.freezeRotation = true;
}
function LateUpdate () {
if(Input.GetAxis("Fire1")==0)return;
if (target) {
x += Input.GetAxis("Mouse X") * xSpeed * distance* 0.02;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
var rotation = Quaternion.Euler(y, x, 0);
distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel")*5, distanceMin, distanceMax);
var hit : RaycastHit;
if (Physics.Linecast (target.position, transform.position, hit)) {
distance -= hit.distance;
}
var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
transform.rotation = rotation;
transform.position = position;
}
}
