Cocos2d-X使用CCAnimation创建动画
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);
return s;
}
bool Animation::init()
{
CCLayer::init();
CCSize winSize = 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(int i = 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, 0, 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));
return true;
}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
<?xml version="1.0" encoding="UTF-8"?>

//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
arr->addObject(frame);
}
//使用数组创建动画
CCAnimation* animation = CCAnimation::createWithSpriteFrames(arr, 0.1f);

//动画消失
CCCallFunc* callfunc = CCCallFunc::create(sp, callfunc_selector(CCSprite::removeFromParent));
CCSequence* seq = CCSequence::create(animate, callfunc, NULL);
//播放动画
sp->runAction(seq);
return true;
