Flash笔记之刷新人物

clockWise//是否顺时针播放

rameCount="8" 表示八方向，每方向8帧。
frameRate="6" 表示人物刷新频率。_curFrame（当前帧和frameRate比较）
isLoop="1"??? 表示是否循环播放。如果人物死亡，就为0 ，不播放。

1--8代表图片m9444_stand_(1--8)

?1.因为5是镜像3的图片，6是镜像2的图片，7是镜像1的图片
?2.如果如果当前是_dir =5 那么久镜像3图片
?3._scaleFrame =25帧（为什么要去25帧，这是因为找到m9811_stand_25这张png图片，再根据?this.hasFlip=true
?把图片this.scaleX = -1;当this.scaleX 为负数时候，翻转功能。
?）????
?4.this.hasFlip = true镜像一定为true
?5.如果是5，那么读取的还是3的xml值。

?1.如果当前是_dir =4
?2._scaleFrame =33帧
?3.this.hasFlip = false 不镜像
