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

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。
