做到汽车的开关门，原本我是用代码进行控制，在update函数中只要让他旋转到一定的角度就OK了，但后来发现这样实现的效果并不好，所以就决定用动画来实现开关门的效果。
操作步骤：
1.Project->Add Tab->Animation 来创建动画，然后来创建帧动画。
2.创建完毕之后，可以给关门的最后一帧添加一个事件，但必须确保事件的函数脚本跟动画附着在同一个物体上，然后双击事件指定事件函数。
说明：由于开门关门就是一个重复的相反的动画，所以开门和关门就做了一个动画-开门的动画，关门只需要倒播就行了。
代码：
播放关门声音
using UnityEngine;
using System.Collections;
public class playMusic : MonoBehaviour {
public AudioClip music = null;
private GameObject camera;
public float musicVolume = 0.6f;
private AudioSource music_A = null;
// Use this for initialization
void Start () {
//music = GameObject.Find("closedoor1");
camera = GameObject.Find("Main Camera");
music_A = camera.AddComponent<AudioSource>();
//添加声音
music_A.clip = music;
music_A.volume = musicVolume;
}
// Update is called once per frame
void Update () {
}
int i = 0;
void PlayMusic()
{
if (i != 0)
{
music_A.Play();
}
i++;
i = i % 2;
}
}
