重力感应操控（unity iphone）

刀锋狼

方案一：speed

1. public var simulateAccelerometer:boolean = false;
   
2. var speed = 10.0;
   
3. function Update () {
   
4.     var dir : Vector3 = Vector3.zero;
   
5.     if (simulateAccelerometer)
   
6.     {
   
7.         dir.x = Input.GetAxis("Horizontal");
   
8.         dir.y = Input.GetAxis("Vertical");
   
9.     }
   
10.     else
    
11.     {
    
12.         dir.x = Input.acceleration.x;
    
13.         dir.y = Input.acceleration.y;
    
14.      
    
15.         // clamp acceleration vector to unit sphere
    
16.         if (dir.sqrMagnitude > 1)
    
17.             dir.Normalize();
    
18.         // Make it move 10 meters per second instead of 10 meters per frame...
    
19.     }
    
20.     dir *= Time.deltaTime;
    
21.     // Move object
    
22.     transform.Translate (dir * speed);
    
23. }

也可以把速度换成力

方案二：Force

1. public var force:float = 1.0;
   
2. public var simulateAccelerometer:boolean = false;
   
3. 
   
4. function FixedUpdate () {
   
5.     var dir : Vector3 = Vector3.zero;
   
6. 
   
7.     if (simulateAccelerometer)
   
8.     {
   
9.         // using joystick input instead of iPhone accelerometer
   
10.         dir.x = Input.GetAxis("Horizontal");
    
11.         dir.y = Input.GetAxis("Vertical");
    
12.     }
    
13.     else
    
14.     {
    
15.         // we assume that device is held parallel to the ground
    
16.         // and Home button is in the right hand
    
17.          
    
18.         // remap device acceleration axis to game coordinates
    
19.         // 1) XY plane of the device is mapped onto XZ plane
    
20.         // 2) rotated 90 degrees around Y axis
    
21.         dir.x = Input.acceleration.y;
    
22.         dir.y = Input.acceleration.x;
    
23.          
    
24.         // clamp acceleration vector to unit sphere
    
25.         if (dir.sqrMagnitude > 1)
    
26.             dir.Normalize();
    
27.     }
    
28.      
    
29.     rigidbody.AddForce(dir * force);
    
30. }

个人感觉方案一操控起来比较灵活，反应灵敏。方案二操控起来具有惯性，缓冲明显。
