重力感应操控（unity iphone）方案二

奔跑的小兔

方案二：Force
public var force:float = 1.0;
02 public var simulateAccelerometer:boolean = false;
03   
04 function FixedUpdate () {
05     var dir : Vector3 = Vector3.zero;
06   
07     if (simulateAccelerometer)
08     {
09         // 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;         
24         // clamp acceleration vector to unit sphere
25         if (dir.sqrMagnitude > 1)
26             dir.Normalize();
27     }
28      
29     rigidbody.AddForce(dir * force);
30 }
