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
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();
}
