Cocos2d-x学习笔记之动画的处理

第一步解析plist文件，这个可以调用函数实现，加载为动画缓存（animationCache）

#include"core/boy.h" #include "cocos2d.h" #include "core/Singleton.h"  using namespace cocos2d;  struct  ObjectAnimation {     char *animateName;//动画名：对应文件开头     int frameNum;//帧数     int starFrame; };  extern ObjectAnimation comboAnimation[6];  class CCParsePlistAnimation:public Singleton<CCParsePlistAnimation> { public:     bool loadAnimation(ObjectAnimation *af,int count);     cocos2d::CCAnimate* getAnimate(char *name);     CCAnimation* getAnimation(char* name); private:     char *getAnimationName(char *name); };  #define sCCParsePlistAnimation CCParsePlistAnimation::getInstance()   #endif//  #include "Common\CCParsePlistAnimation.h"//120 #include"DBgame.h" using namespace cocos2d;  static char charBuffer[128];  //af[1].animateName is plist ObjectAnimation comboAnimation[6]= {     {"gameObject",0,0},     {"combo",3,0},     {"coin",8,0},     {"cube",8,0},     {"critical_text",5,0},     {"box",6,0}, };  bool CCParsePlistAnimation::loadAnimation(ObjectAnimation *af,int count) {     //缓冲——这会加载对应的png，并裁切成SpriteFrame，而且还会完成索引     memset(charBuffer,0,sizeof(charBuffer));     sprintf(charBuffer,"objectTexture/16bit/4444-%s.plist",af[0].animateName);      printf("OBJECTANIMATION:------%s\n",charBuffer);     CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile(charBuffer);     //创建动画数据     CCMutableArray<CCSpriteFrame*> *spriteFrames = new CCMutableArray<CCSpriteFrame*>();     for (int i=1;i<count;i++)     {         for(int j=af[i].starFrame;j<af[i].starFrame+af[i].frameNum;j++)         {             memset(charBuffer,0,sizeof(charBuffer));             sprintf(charBuffer,"%s_%d.png",af[i].animateName,j);                          printf("objectPicture:--------%s\n",charBuffer);               CCSpriteFrame *spriteFrame=CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(charBuffer);             spriteFrames->addObject(spriteFrame);          }         //使用cache缓冲管理         CCAnimation *animation=CCAnimation::animationWithFrames(spriteFrames,0.2f);         memset(charBuffer,0,sizeof(charBuffer));          sprintf(charBuffer,"%s",af[i].animateName);          printf("objAnimation:%s\n",charBuffer);          CCAnimationCache::sharedAnimationCache()->addAnimation(animation,charBuffer);         spriteFrames->removeAllObjects();     }     spriteFrames->release();      return true; } cocos2d::CCAnimate* CCParsePlistAnimation::getAnimate(char *name) {     CCAnimation* animation=CCAnimationCache::sharedAnimationCache()->animationByName(getAnimationName(name));          if(animation)     {         return cocos2d::CCAnimate::actionWithAnimation(animation);     }     return NULL; } CCAnimation* CCParsePlistAnimation::getAnimation(char* name) {     CCAnimation* animation=CCAnimationCache::sharedAnimationCache()->animationByName(getAnimationName(name));      if(animation)     {         return animation;     }     return NULL;  } char* CCParsePlistAnimation::getAnimationName(char *name ) {     memset(charBuffer,0,sizeof(charBuffer));     sprintf(charBuffer,"%s",name);     return charBuffer; }

接下来进行初始化在HelloWorldScene的init函数中初始化.

sCCParsePlistAnimation->loadAnimation(comboAnimation,6);

下面的部分就是动画与sprite的结合的一些实用了，以及或许会遇到的动画播放的细节的举列。
