Input.GetAccelerationEvent

説明

最後のフレーム間で発生した加速度を返します（一時的な変数は割り当てられません）

using UnityEngine;

public class Example : MonoBehaviour
{
    // Calculates weighted sum of acceleration measurements which occurred during the last frame
    // Might be handy if you want to get more precise measurements
    void Update()
    {
        Vector3 acceleration = Vector3.zero;
        for (var i = 0; i < Input.accelerationEventCount; ++i)
        {
            AccelerationEvent accEvent = Input.GetAccelerationEvent(i);
            acceleration += accEvent.acceleration * accEvent.deltaTime;
        }
        print(acceleration);
    }
}
