动画在游戏中是非常常见的
程序1:创建一个简单的动画
首先需要在工程目录下的Resource文件夹中放一张有各种不同动作的图片
在程序中添加下面的代码
- #include"Animation.h"
-
- CCScene*Animation::scene()
- {
- CCScene*s=CCScene::create();
- Animation*layer=Animation::create();
- s->addChild(layer);
- returns;
- }
-
- boolAnimation::init()
- {
- CCLayer::init();
- CCSizewinSize=CCDirector::sharedDirector()->getWinSize();
-
- CCSprite*sp=CCSprite::create();
- sp->setPosition(ccp(winSize.width/2,winSize.height/2));
- addChild(sp);
-
- sp->setScale(4);
- //创建纹理
- CCTexture2D*texture=CCTextureCache::sharedTextureCache()->addImage("walkLeft.png");
- //创建一个数组
- CCArray*arr=CCArray::create();
- //从纹理中扣了10帧frame,组成数组
- for(inti=0;i<10;i++)
- //使用纹理创建精灵帧
- //第一个参数:纹理
- //第二个参数:矩形
- CCSpriteFrame*frame=CCSpriteFrame::createWithTexture(texture,
- //第一个参数:矩形的x坐标
- //第二个参数:矩形的y坐标
- //第三个参数:矩形的宽度
- //第四个参数:矩形的高度
- CCRect(i*18,18,32));
- arr->addObject(frame);
- }
- //使用精灵帧创建动画
- //第一个参数:数组
- //第二个参数:动画的帧数(播放两张图片的间隔时间)
- CCAnimation*animation=CCAnimation::createWithSpriteFrames(arr,0.1f);
- CCAnimate*animate=CCAnimate::create(animation);
- //播放动画
- //CCRepeatForever::create动画播放无限次
- sp->runAction(CCRepeatForever::create(animate));
- returntrue;
- }
执行结果:
程序2:有plist文件的动画加载
首先需要在工程目录下的Resource文件夹中放一张有各种不同动作的图片和一个plist文件
plist格式的文件实际上是一个XML文件,文件中的内容
<?xmlversion="1.0"encoding="UTF-8"?>
- <!DOCTYPEplistPUBLIC"-//AppleComputer//DTDPLIST1.0//EN""http://www.apple.com/DTDs/PropertyList-1.0.dtd">

程序代码:
//有plist文件的动画加载
- boolAnimation::init()
- CCLayer::init();
- CCSizewinSize=CCDirector::sharedDirector()->getWinSize();
- //创建精灵
- CCSprite*sp=CCSprite::create();
- sp->setPosition(ccp(winSize.width/2,winSize.height/2));
- addChild(sp);
- //精灵放大4倍
- sp->setScale(4);
- //创建精灵帧缓存
- CCSpriteFrameCache*frameCache=CCSpriteFrameCache::sharedSpriteFrameCache();
- //创建数组
- //添加Plist文件
- frameCache->addSpriteFramesWithFile("PFBoom.plist");
- inti=1;i<=18;i++)
- charkey[128];
- //通过名字获取精灵帧所在的图片
- sprintf(key,"Boom_%d.png",i);
- //将图片添加到精灵帧中
- CCSpriteFrame*frame=frameCache->spriteFrameByName(key);
- //将精灵帧添加到数组中
- //使用数组创建动画
- //动画消失
- CCCallFunc*callfunc=CCCallFunc::create(sp,callfunc_selector(CCSprite::removeFromParent));
- CCSequence*seq=CCSequence::create(animate,callfunc,NULL);
- sp->runAction(seq);
- true;
- }
执行结果:
程序3:通过鼠标实现动画切换
首先创建一个Animation类
在AnimationPreload.h中添加下面代码
#ifndef__AnimationPreload_H__
- #define__AnimationPreload_H__
- #include"cocos2d.h"
- USING_NS_CC;
- classAnimationPreload:publicCCLayer
- public:
- staticCCScene*scene();
- boolinit();
- CREATE_FUNC(AnimationPreload);
- boolccTouchBegan(CCTouch*,CCEvent*);
- CCSprite*sp;
- };
- #endif
在AnimationPreload.cpp中添加下面的代码
#include"AnimationPreload.h"
- CCScene*AnimationPreload::scene()
- AnimationPreload*layer=AnimationPreload::create();
- boolAnimationPreload::init()
- //chushihu
- //获取窗口的大小
- //(创建纹理)从纹理里扣了10帧frame,组成数组
- CCArray*arr=CCArray::create();
- inti=9;i>=0;i--)
- //创建精灵帧
- CCSpriteFrame*frame=CCSpriteFrame::createWithTexture(texture,
- //将精灵帧添加到数组中
- arr->addObject(frame);
- //通过数组创建动画
- CCAnimation*animation=CCAnimation::createWithSpriteFrames(arr,0.05f);
- //加入到缓存
- CCAnimationCache::sharedAnimationCache()->addAnimation(animation,"MarioRun");
- /***************************************************************/
- /**有plist文件的动画加载**/
- arr=CCArray::create();
- //将plist文件添加到精灵帧缓存中
- //创建动画
- animation=CCAnimation::createWithSpriteFrames(arr,0); background-color:inherit">//加入到缓存
- CCAnimationCache::sharedAnimationCache()->addAnimation(animation,"PlaneBOOM");
- sp=CCSprite::create();
- //精灵方法4倍
- //setTouch
- setTouchEnabled(true);
- setTouchMode(kCCTouchesOneByOne);
- boolAnimationPreload::ccTouchBegan(CCTouch*,CCEvent*)
- sp->stopAllActions();
- staticinti=1;
- if(i==1)
- sp->runAction(CCAnimate::create(
- CCAnimationCache::sharedAnimationCache()->animationByName("PlaneBOOM")
- ));
- else
- CCAnimationCache::sharedAnimationCache()->animationByName("MarioRun")
- i=1-i;
- return0;
- }
执行结果:
