    Flick判定
    >任意方向Flick:只有Prefect判定,在其抵达目标时间时,在5个单位长度内手指处于移动状态即可完成判定,早于目标时间不判定,超过g判区间触发miss事件
    >指定方向note:有Great.Prefect判定,在3个单位长度内初次被击中时,变为激发态,启动[滑动检查],超过g判区间触发miss事件
    ->滑动检查:在每一帧检查手指ID,手指位移,手指位移方向是否正确,当三者均满足时,与标准时间进行比较,触发对应事件
    ->条件:初始点为第一次击中点,,每一帧更新目标手指ID的手指目前位置,当向量模长为2单位长度,且方向与标准向量夹角不超过π/2,开始结算
