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"?>

    CCScene* s = CCScene::create();

    Animation* layer = Animation::create();

    s->addChild(layer);

    return s;
}

//有plist文件的动画加载
bool Animation::init()

    CCSize winSize = CCDirector::sharedDirector()->getWinSize();

    //创建精灵
    CCSprite* sp = CCSprite::create();

    //添加Plist文件
    frameCache->addSpriteFramesWithFile("PFBoom.plist");

	for (int i = 1; i <= 18; i++)
	{

	}

    //使用数组创建动画
	CCAnimation* animation = CCAnimation::createWithSpriteFrames(arr, 0.1f);
	CCAnimate* animate = CCAnimate::create(animation);

    //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;
}

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;

class AnimationPreload : public CCLayer
{
public:
    static CCScene* scene();
    
    bool init();

    CREATE_FUNC(AnimationPreload);
    
    bool ccTouchBegan(CCTouch*, CCEvent*);

    CCSprite* sp;
};

#endif

在AnimationPreload.cpp中添加下面的代码

#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();

    //获取窗口的大小
    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 **/

    //创建精灵帧缓存
	CCSpriteFrameCache* frameCache = CCSpriteFrameCache::sharedSpriteFrameCache();

    //创建数组
	arr = CCArray::create();

    //将plist文件添加到精灵帧缓存中
	frameCache->addSpriteFramesWithFile("PFBoom.plist");

	for (int i = 1; i <= 18; i++)
	{
		char key[128];
