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
#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*18,18,32));
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
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>frames</key> <dict> <key>Boom_1.png</key> <dict> <key>frame</key> <string>{{204,305},{99,99}}</string> <key>offset</key> <string>{0,0}</string> <key>rotated</key> <false/> <key>sourceColorRect</key> <string>{{0,0},99}}</string> <key>sourceSize</key> <string>{99,99}</string> </dict> <key>Boom_10.png</key> <dict> <key>frame</key> <string>{{103,307},99}</string> </dict> <key>Boom_11.png</key> <dict> <key>frame</key> <string>{{103,206},99}</string> </dict> <key>Boom_12.png</key> <dict> <key>frame</key> <string>{{105,2},99}</string> </dict> <key>Boom_13.png</key> <dict> <key>frame</key> <string>{{103,105},99}</string> </dict> <key>Boom_14.png</key> <dict> <key>frame</key> <string>{{2,{101,101}}</string> <key>offset</key> <string>{0,101}}</string> <key>sourceSize</key> <string>{101,101}</string> </dict> <key>Boom_15.png</key> <dict> <key>frame</key> <string>{{2,408},99}</string> </dict> <key>Boom_16.png</key> <dict> <key>frame</key> <string>{{2,99}</string> </dict> <key>Boom_17.png</key> <dict> <key>frame</key> <string>{{2,99}</string> </dict> <key>Boom_18.png</key> <dict> <key>frame</key> <string>{{2,99}</string> </dict> <key>Boom_2.png</key> <dict> <key>frame</key> <string>{{204,204},99}</string> </dict> <key>Boom_3.png</key> <dict> <key>frame</key> <string>{{406,103},99}</string> </dict> <key>Boom_4.png</key> <dict> <key>frame</key> <string>{{305,99}</string> </dict> <key>Boom_5.png</key> <dict> <key>frame</key> <string>{{204,99}</string> </dict> <key>Boom_6.png</key> <dict> <key>frame</key> <string>{{408,99}</string> </dict> <key>Boom_7.png</key> <dict> <key>frame</key> <string>{{307,99}</string> </dict> <key>Boom_8.png</key> <dict> <key>frame</key> <string>{{206,99}</string> </dict> <key>Boom_9.png</key> <dict> <key>frame</key> <string>{{103,99}</string> </dict> </dict> <key>Metadata</key> <dict> <key>format</key> <integer>2</integer> <key>realTextureFileName</key> <string>PFBoom.png</string> <key>size</key> <string>{512,512}</string> <key>textureFileName</key> <string>PFBoom.png</string> </dict> </dict> </plist>
程序代码：
#include "Animation.h"
CCScene* Animation::scene()
{
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()
{
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);
//创建精灵帧缓存
CCSpriteFrameCache* frameCache = CCSpriteFrameCache::sharedSpriteFrameCache();
//创建数组
CCArray* arr = CCArray::create();
//添加Plist文件
frameCache->addSpriteFramesWithFile("PFBoom.plist");
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);
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;
}
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
#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
#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*18,32));
//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];
//通过名字获取精灵帧所在的图片
sprintf(key,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
arr->addobject(frame);
}
//创建动画
animation = CCAnimation::createWithSpriteFrames(arr,0.1f);
// 加入到缓存
CCAnimationCache::sharedAnimationCache()->addAnimation(animation,"PlaneBOOM");
sp = CCSprite::create();
sp->setPosition(ccp(winSize.width / 2,winSize.height / 2));
addChild(sp);
//精灵方法4倍
sp->setScale(4);
// setTouch
setTouchEnabled(true);
setTouchMode(kCCtouchesOneByOne);
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
{
sp->runAction(CCAnimate::create(
CCAnimationCache::sharedAnimationCache()->animationByName("MarioRun")
));
}
i = 1 - i;
return 0;
}
