Unity3D iphone的重力感应控制

# unity3D更多资源教程免费下载 iphone重力感应控的两种方法： ## 方案一：speed 也可以把速度换成力。 脚本如下： ```csharp 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); } 

方案二：Force

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); } 

总结：方案一，操控比较灵活，反应灵敏。方案二，操控具有惯性，缓冲明显。
