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*18,18,32)); 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"?><!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
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*18,32)); //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;}
