Input.GetAccelerationEvent 获取加速度事件

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void Update() {
		Vector3 acceleration = Vector3.zero;
		int i = 0;
		while (i < Input.accelerationEventCount) {
			AccelerationEvent accEvent = Input.GetAccelerationEvent(i);
			acceleration += accEvent.acceleration * accEvent.deltaTime;
			++i;
		}
		print(acceleration);
	}
}

// Calculates weighted sum of acceleration measurements which occurred during the last frame
// Might be handy if you want to get more precise measurements
//计算加速度测量加权求和，发生在最后一帧可能会很方便，如果你想获得更精确的测量

function Update () {
	var acceleration:Vector3 = Vector3.zero;
	for (var i = 0; i < Input.accelerationEventCount; ++i) {
		var accEvent:AccelerationEvent = Input.GetAccelerationEvent(i);
		acceleration += accEvent.acceleration * accEvent.deltaTime;
	}
	print (acceleration);
}
