## 描述

最近测量的设备在三维空间中的线性加速度。（只读）

```
using UnityEngine;

public class Example : MonoBehaviour
{
    // Move object using accelerometer
    float speed = 10.0f;

void Update()
    {
        Vector3 dir = Vector3.zero;

// 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.z = Input.acceleration.x;

// 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);
    }
}
