cocos2d -x 技能按键实现

自己写了一个技能栏的工具，希望对各位游戏开发者有用。部分函数使用了我上一篇文章中的hashtable。

测试代码如下，附件中为测试图片,部分图片来自网络，仅供学习参考，请勿商用，后果自负。

CCSprite *normal=CCSprite::spriteWithFile("fire_normal.png");
CCSprite *select=CCSprite::spriteWithFile("fire_press.png");
    CCSprite *testselectbg=CCSprite::spriteWithFile("r1-hd.png");
testselectbg->setOpacity(100);
SkillBar *sb=SkillBar::createSkillBar(normal,select,testselectbg,10.0f,CCCallFuncN::actionWithTarget(this,callfuncN_selector(HelloWorld::menuCloseCallback)));
sb->addSkillBar(CCSprite::spriteWithFile("fire_press.png"),CCSprite::spriteWithFile("fire_normal.png"),CCSprite::spriteWithFile("r1-hd.png"),4.0f,CCCallFuncN::actionWithTarget(this,callfuncN_selector(HelloWorld::menuCloseCallback)));
sb->addSkillBar(CCSprite::spriteWithFile("fire_press.png"),CCSprite::spriteWithFile("fire_normal.png"),CCSprite::spriteWithFile("r1-hd.png"),8.0f,CCCallFuncN::actionWithTarget(this,callfuncN_selector(HelloWorld::menuCloseCallback)));
this->addChild(sb);
CCSprite * gamebg=CCSprite::spriteWithTexture(CCTextureCache::sharedTextureCache()->textureForKey(png_playbg));
sb->setSkillBarBg(gamebg);
sb->setPosition(ccp(0,screenSize.height/2));
