使用普通方法实现批处理精灵

在Sprite.h中加入以下的代码

#ifndef __Sprite_SCENE_H__
#define __Sprite_SCENE_H__ #include "cocos2d.h"
USING_NS_CC; class Sprite : public CCLayer
{
public: //初始化层
bool init(); //创建场景
static CCScene* scene(); //响应触摸
bool Sprite::ccTouchBegan(CCTouch* touch, CCEvent*); //用于创建:场景、菜单、层等东西
CREATE_FUNC(Sprite);
}; #endif // __Sprite_SCENE_H__

在Sprite.cpp中加入以下的代码

#include "Sprite.h"

USING_NS_CC;

//创建场景
CCScene* Sprite::scene()
{
//创建场景
CCScene *scene = CCScene::create(); //创建层
Sprite *layer = Sprite::create(); //将层加到场景上
scene->addChild(layer); //返回场景
return scene;
} //初始化实例句柄
bool Sprite::init()
{
//初始化父类CCLayer
CCLayer::init(); //得到窗体的尺寸
CCSize winSize = CCDirector::sharedDirector()->getWinSize(); //设置坐标
CCPoint ptCenter = ccp(winSize.width / 2, winSize.height / 2); //创建一个批处理结点容器
CCSpriteBatchNode* batch = CCSpriteBatchNode::create("CloseNormal.png"); //将精灵加到层中
addChild(batch); //使用纹理创建精灵
CCSprite* sprite = CCSprite::createWithTexture(batch->getTexture()); //将精灵加到容器上
batch->addChild(sprite); //设置精灵的位置
sprite->setPosition(ptCenter); //设置触摸
setTouchEnabled(true);
setTouchMode(kCCTouchesOneByOne); return true;
} //响应触摸
bool Sprite::ccTouchBegan(CCTouch* touch, CCEvent*)
{
//得到窗体的尺寸
CCSize winSize = CCDirector::sharedDirector()->getWinSize(); //循环100次,创建1000个精灵
for (int i = 0; i < 1000; i++)
{
//创建精灵
CCSprite* sprite = CCSprite::create("CloseNormal.png"); //将精灵加入到层上
addChild(sprite); //设置精灵的位置
sprite->setPosition(ccp(CCRANDOM_0_1()*winSize.width, CCRANDOM_0_1()* winSize.height));
} return true;
}

运行结果:

1、打开程序后的效果:启动程序后帧率为58.7

Cocos2d-X中实现批处理精灵-LMLPHP

2、单击3次鼠标后的效果:单击三次鼠标后实现了批处理精灵帧率降低

使用纹理实现批处理精灵

在Sprite.h中加入以下的代码

#ifndef __Sprite_SCENE_H__
#define __Sprite_SCENE_H__ #include "cocos2d.h"
USING_NS_CC; class Sprite : public CCLayer
{
public: //初始化层
bool init(); //创建场景
static CCScene* scene(); //响应触摸
bool Sprite::ccTouchBegan(CCTouch* touch, CCEvent*); CCSpriteBatchNode* _batch; //用于创建:场景、菜单、层等东西
CREATE_FUNC(Sprite);
}; #endif // __Sprite_SCENE_H__

Sprite.cpp中的代码

#include "Sprite.h"

USING_NS_CC;

//创建场景
CCScene* Sprite::scene()
{
//创建场景
CCScene *scene = CCScene::create(); //创建层
Sprite *layer = Sprite::create(); //将层加到场景上
scene->addChild(layer); //返回场景
return scene;
} //初始化实例句柄
bool Sprite::init()
{
//初始化父类CCLayer
CCLayer::init(); //得到窗体的尺寸
CCSize winSize = CCDirector::sharedDirector()->getWinSize(); //设置坐标
CCPoint ptCenter = ccp(winSize.width / 2, winSize.height / 2); //批处理精灵
CCSpriteBatchNode* batch = CCSpriteBatchNode::create("CloseNormal.png");
addChild(batch); _batch = batch; CCSprite* sprite = CCSprite::createWithTexture(batch->getTexture()); batch->addChild(sprite); sprite->setPosition(ptCenter); setTouchEnabled(true);
setTouchMode(kCCTouchesOneByOne); return true;
} //响应触摸
bool Sprite::ccTouchBegan(CCTouch* touch, CCEvent*)
{
CCSize winSize = CCDirector::sharedDirector()->getWinSize(); for (int i = 0; i < 1000; i++)
{
CCSprite* sprite = CCSprite::createWithTexture(_batch->getTexture()); _batch->addChild(sprite); sprite->setPosition(ccp(CCRANDOM_0_1()*winSize.width, CCRANDOM_0_1()* winSize.height));
} return true;
}

运行结果:

1、打开程序后的效果:启动程序后帧率为58.7

Cocos2d-X中实现批处理精灵-LMLPHP

2、单击多次后的效果,帧率没有明显变化

说明:CCSpriteBatchNode也是一个容器,可是它仅仅能包容CCSprite对象,并且要求这些精灵来自同一个纹理
