Cocos2d-X使用CCAnimation创建动画
动画在游戏中是很常见的
程序1：创建一个简单的动画
首先须要在project文件夹下的Resource文件夹中放一张有各种不同动作的图片
在程序中加入以下的代码
#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
//第一个參数：纹理
//第二个參数：矩形
CCSpriteFrame* frame = CCSpriteFrame::createWithTexture(texture,
//第一个參数：矩形的x坐标
//第二个參数：矩形的y坐标
//第三个參数：矩形的宽度
//第四个參数：矩形的高度
CCRect(i*18, 0, 18, 32));
arr->addObject(frame);
}
//使用精灵帧创建动画
//第一个參数：数组
//第二个參数：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;
}
运行结果：
程序2：有plist文件的动画载入
首先须要在project文件夹下的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，文件里的内容
<?xml version="1.0" encoding="UTF-8"?>

//动画消失

CCSequence* seq = CCSequence::create(animate, callfunc, NULL);
//播放动画
sp->runAction(seq);
return true;
}运行结果：
程序3：通过鼠标实现动画切换
首先创建一个Animation类
在AnimationPreload.h中加入以下代码
#ifndef __AnimationPreload_H__
#define __AnimationPreload_H__
#include "cocos2d.h"
USING_NS_CC;
class AnimationPreload : public CCLayer
{
public:
static CCScene* scene();
bool init();
CREATE_FUNC(AnimationPreload);
bool ccTouchBegan(CCTouch*, CCEvent*);
CCSprite* sp;
};
#endif
在AnimationPreload.cpp中加入以下的代码
#include "AnimationPreload.h"
CCScene* AnimationPreload::scene()
{
CCScene* s = CCScene::create();
AnimationPreload* layer = AnimationPreload::create();
s->addChild(layer);
return s;
}
bool AnimationPreload::init()
{
//chushihu
CCLayer::init();
//获取窗体的大小
CCSize winSize = CCDirector::sharedDirector()->getWinSize();
//(创建纹理)从纹理里扣了10帧frame。组成数组
CCTexture2D* texture = CCTextureCache::sharedTextureCache()->addImage("walkLeft.png");
//创建数组
CCArray* arr = CCArray::create(); //retain
for (int i = 9; i >= 0; i--)
{
//创建精灵帧
CCSpriteFrame* frame = CCSpriteFrame::createWithTexture(texture,
CCRect(i*18, 0, 18, 32));
//将精灵帧加入到数组中
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文件的动画载入 **/
//创建精灵帧缓存
CCSpriteFrameCache* frameCache = CCSpriteFrameCache::sharedSpriteFrameCache();
//创建数组

for (int i = 1; i <= 18; i++)
{
char key[128];
//通过名字获取精灵帧所在的图片
sprintf(key, "Boom_%d.png", i);
//将图片加入到精灵帧中
CCSpriteFrame* frame = frameCache->spriteFrameByName(key);

}
//创建动画

return true;
}
bool AnimationPreload::ccTouchBegan(CCTouch*, CCEvent*)
{
sp->stopAllActions();
static int i = 1;
if (i == 1)
{
sp->runAction(CCAnimate::create(
CCAnimationCache::sharedAnimationCache()->animationByName("PlaneBOOM")

}
else
{

}
i = 1 - i;
return 0;
}
运行结果：
