Input.acceleration

描述

设备在三维空间中测量的最新线性加速度。 （只读）

注意：此 API 是旧版 Input 类的一部分，不推荐用于新项目。提供此文档是为了支持使用旧版输入管理器和输入类的旧项目。对于新项目，您应该使用更新的 Input System Package。 (了解更多).

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);
    }
