标题: 重力感应操控（Unity iPhone）的两种方案

方案一：speed
01 public var simulateAccelerometer:boolean = false;
02 var speed = 10.0;
03 function Update () {
04    var dir : Vector3 = Vector3.zero;
05    if (simulateAccelerometer)
06    {
07       dir.x = Input.GetAxis("Horizontal");
08       dir.y = Input.GetAxis("Vertical");
09    }
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
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 }
