标题: 调用unity3d iphone的重力感应_代码
方案一：speed

public var simulateAccelerometer:boolean = false;




var speed = 10.0;




function Update () {




      var dir : Vector3 = Vector3.zero;




      if (simulateAccelerometer)




      {




         dir.x = Input.GetAxis("Horizontal");




         dir.y = Input.GetAxis("Vertical");




      }




      else




      {




         dir.x = Input.acceleration.x;




         dir.y = Input.acceleration.y;









         // clamp acceleration vector to unit sphere




         if (dir.sqrMagnitude > 1)




            dir.Normalize();




         // Make it move 10 meters per second instead of 10 meters per frame...




      }




      dir *= Time.deltaTime;


      // Move object




      transform.Translate (dir * speed);




}

也可以把速度换成力

方案二：Force

view sourceprint?

public var force:float = 1.0;




public var simulateAccelerometer:boolean = false;








function FixedUpdate () {




      var dir : Vector3 = Vector3.zero;








      if (simulateAccelerometer)




      {




         // using joystick input instead of iPhone accelerometer




         dir.x = Input.GetAxis("Horizontal");




         dir.y = Input.GetAxis("Vertical");




      }




      else




      {




         // we assume that device is held parallel to the ground




         // and Home button is in the right hand









         // remap device acceleration axis to game coordinates




         // 1) XY plane of the device is mapped onto XZ plane




         // 2) rotated 90 degrees around Y axis




         dir.x = Input.acceleration.y;




         dir.y = Input.acceleration.x;









         // clamp acceleration vector to unit sphere




         if (dir.sqrMagnitude > 1)




            dir.Normalize();




      }









      rigidbody.AddForce(dir * force);




}

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。
