cocos2d-x之新手学习留痕（一）——helloWorld+button+animation
没学过c++,因cocos2d-x能做游戏，所以，开始了悲剧的开始。。。。。。
新建一个cocos2d-x的工程，找到source包中的HelloWorldScene.cpp，
在bool HelloWorld::init()这个方法中，删除系统自动生成的代码，自己写了如下的代码
1 bool HelloWorld::init() 2 { 3 bool bRet = false; 4 do 5 { 6 CC_BREAK_IF(! CCLayer::init()); 7 8 //加入文字 9 CCLabelTTF* pLabel = CCLabelTTF::create("hello cjj","Arial",24); 10 //检查指针 11 CC_BREAK_IF(! pLabel); 12 CCSize size = CCDirector::sharedDirector()->getWinSize(); 13 //设置位置 14 pLabel->setPosition(ccp(size.width/3,size.height/2)); 15 this->addChild(pLabel,1); 16 17 //加入退出按钮 18 CCMenuItemImage *pCloseItem = CCMenuItemImage::create( 19 "CloseNormal.png",//按钮正常情况 20 "CloseSelected.png",//按钮按下之后 21 this,menu_selector(HelloWorld::menuCloseCallback)//回调函数，退出程序 22 ); 23 24 CC_BREAK_IF(!pCloseItem); 25 pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width-20,20)); 26 //创建menu 27 CCMenu* pMenu = CCMenu::create(pCloseItem,NULL); 28 CC_BREAK_IF(!pMenu); 29 pMenu->setPosition(CCPointZero); 30 this->addChild(pMenu,1); 31 32 //绘制背景图片 33 CCSprite* pSprite = CCSprite::create("7.jpg"); 34 CC_BREAK_IF(! pSprite); 35 pSprite->setPosition(ccp(size.width/2,size.height/2)); 36 this->addChild(pSprite,0); 37 38 39 //获得帧 40 CCTexture2D* pTexture = CCTextureCache::sharedTextureCache()->addImage("you.png"); 41 CCSpriteFrame* pFrame0 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*0,81,94)); 42 CCSpriteFrame* pFrame1 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*1,81,94)); 43 CCSpriteFrame* pFrame2 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*2,81,94)); 44 CCSpriteFrame* pFrame3 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*3,81,94)); 45 CCSpriteFrame* pFrame4 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*4,81,94)); 46 CCSpriteFrame* pFrame5 = CCSpriteFrame::createWithTexture(pTexture,CCRectMake(0,94*5,81,94)); 47 CCArray *pArray=CCArray::create(); 48 pArray->addObject(pFrame0); 49 pArray->addObject(pFrame1); 50 pArray->addObject(pFrame2); 51 pArray->addObject(pFrame3); 52 pArray->addObject(pFrame4); 53 pArray->addObject(pFrame5); 54 //创建动画 55 CCAnimation* pAnimation = CCAnimation::createWithSpriteFrames(pArray,0.5); 56 CC_BREAK_IF(! pAnimation); 57 58 //创建精灵 59 CCSprite* pSprtieYou = CCSprite::createWithSpriteFrame(pFrame0); 60 CC_BREAK_IF(!pSprtieYou); 61 pSprtieYou->setPosition(ccp(size.width/3,size.height/3)); 62 this->addChild(pSprtieYou,2); 63 //播放动画 64 CCAnimate* pAnimate = CCAnimate::create(pAnimation); 65 pSprtieYou->runAction(CCRepeatForever::create(pAnimate)); 66 67 bRet = true; 68 } while (0); 69 70 return bRet; 71 }
运行下程序，就有这种效果了 ，当然，前提是要有图片资源：
效果：
恩恩，就这样，至少第一篇不像随笔的随笔完成了，再接再悲剧吧。。。。。。
