/*
*19  精灵的各种应用
*/
1，锚点

锚点就是所有旋转，移动，缩放的参考点。cocos2-x中默认的锚点是中心点。锚点用比例来表示范围为0-1，（0,0)点代表左下点，(1,1)代表右上点。设置的函数为setAnchorPoint(ccp(0.5, 0.5));

2，旋转

setRotation(angle) 其中angle为角度不是弧度。正数为顺时针旋转，负数为逆时针旋转。

3，位置

setPosition(ccp(xPos, yPos)) xPos和yPos为相对于父节点锚点的位置。

4，缩放

setScale(s);   // 整体缩放

setScaleX(s); // 原图片坐标X轴缩放

setScaleY(s); // 原图片坐标Y轴缩放

s为比例，s = 1表示原尺寸。

5，倾斜

setSkewX(s); // 原图片坐标X轴倾斜

setSkewY(s); // 原图片坐标Y轴倾斜

X轴向右为正，Y轴向上为正。

6，透明度

setOpacity(s);

s范围0-255,0完全透明，255完全不透明。

7，可见

setIsVisible(bVisible)

bVisible为bool值true代表可见false代表不可见

8，翻转

setFlipX(bFlip);  // 水平翻转

setFlipY(bFlip);  // 竖直翻转

bFlip为true，则图片翻转，false不翻转。注意，翻转是针对原图片的操作，水平翻转相当于在图片编辑软件里水平翻转一样。不根据锚点进行翻转。翻转以后，设置的以前设置的锚点不会随着图片的翻转而改变。比如设置右下角为锚点，则翻转以后，锚点为翻转后的图片的右下角（是不是有点绕？）

最后，初始化完成后，不要忘了使用addChild加入到父节点，否则是不会显示的。
