/// </summary>
public class UI_2DEffect : MonoBehaviour
{
    private Image img;//图片组件

    [Header("资源目录")]
    public string resDir;

    [Header("总帧数")]
    [Space(25)]
    public int totalFarme;
    [Header("帧率")]
    public int frameRate;

    [Header("是否自动播放")]
    [Space(25)]
    public bool autoPlay = false;
    [Header("是否循环播放")]
    public bool isLoop = false;

    private Sprite curSprite;//当前Sprite
    private int curFrame;//当前帧
    private float timer;//计时器
