Cocos2d-X中的ProgressTimer



ProgressTimer即进度条,进度条在游戏开发中运用很广泛,比如在一些格斗游戏中,显示血液的变化,还有游戏载入进度,等都离不开进度条

Cocos2d-X中使用CCProgressTimer创建进度条

先从一个简单的样例使用ProgressTimer屏蔽部分精灵

首先在project文件夹下的Resource文件夹中放一张图片

然后创建一个ProgressTimer类

在ProgressTimer.h中加入以下的代码

#ifndef __ProgressTimer_H__
#define __ProgressTimer_H__

#include "cocos2d.h"
USING_NS_CC;

class ProgressTimer : public CCLayer
{
public:
    virtual bool init();  

    static CCScene* scene();
    
    CREATE_FUNC(ProgressTimer);

   void scheduleFunc(float dt);
};

#endif // __ProgressTimer_H__

在ProgressTimer.cpp中加入以下的代码

#include "ProgressTimer.h"

CCScene* ProgressTimer::scene()
{
    CCScene *scene = CCScene::create();
    
    ProgressTimer *layer = ProgressTimer::create();

    scene->addChild(layer);

    return scene;
}

bool ProgressTimer::init()
{
    //初始化父类
    CCLayer::init();

    //得到窗体的大小
    CCSize winSize = CCDirector::sharedDirector()->getWinSize();

    //设置坐标
    CCPoint center = ccp(winSize.width / 2, winSize.height / 2);

    //创建精灵
    CCSprite* sprite = CCSprite::create("labelatlasimg.png");
   
    //用精灵创建进度条
    CCProgressTimer* progress = CCProgressTimer::create(sprite);
    addChild(progress);

    //设置进度条的位置
    progress->setPosition(center);

    //设置百分比(显示运行进度条的50%)
    progress->setPercentage(50);

    return true;
}

运行结果:


实例2:显示前半部分

#include "ProgressTimer.h"

CCScene* ProgressTimer::scene()
{
    CCScene *scene = CCScene::create();
    
    ProgressTimer *layer = ProgressTimer::create();

    scene->addChild(layer);

    return scene;
}

bool ProgressTimer::init()
{
    //初始化父类
    CCLayer::init();

    //得到窗体的大小
    CCSize winSize = CCDirector::sharedDirector()->getWinSize();

    //设置坐标
    CCPoint center = ccp(winSize.width / 2, winSize.height / 2);

    //创建精灵
    CCSprite* sprite = CCSprite::create("labelatlasimg.png");
   
    //用精灵创建进度条
    CCProgressTimer* progress = CCProgressTimer::create(sprite);
    addChild(progress);

    //设置进度条的位置
    progress->setPosition(center);

   

    //设置进度条的模式
    //kCCProgressTimerTypeBar表示条形模式
    //默认的模式是kCCProgressTimerTypeRadial(圆圈模式)
    progress->setType(kCCProgressTimerTypeBar);

    //设置进度条变化的方向
    //setMidpoint默认在左边
    //ccp(1,0)表示在X轴方向上有变化,在y轴方向上没变化
      //ccp(0,1)表示在X轴方向上没有变化,在y轴方向上有变化
    progress->setBarChangeRate(ccp(1,0));

    //从哪个方向開始变化
    //ccp(0,0)表示从左边開始变化
    progress->setMidpoint(ccp(0,0));


   //设置百分比(显示运行进度条的50%)
    progress->setPercentage(50);

    return true;
}


运行结果:

程序代码:

#include "ProgressTimer.h"

CCScene* ProgressTimer::scene()
{

    ProgressTimer *layer = ProgressTimer::create();

    scene->addChild(layer);

    return scene;
}

bool ProgressTimer::init()
{
    //初始化父类
    CCLayer::init();

    //得到窗体的大小
    CCSize winSize = CCDirector::sharedDirector()->getWinSize();

    //设置坐标
    CCPoint center = ccp(winSize.width / 2, winSize.height / 2);

    //创建精灵
    CCSprite* sprite = CCSprite::create("labelatlasimg.png");
   
    //用精灵创建进度条
    CCProgressTimer* progress = CCProgressTimer::create(sprite);
    addChild(progress);

    //设置进度条的位置
    progress->setPosition(center);


    //设置progress的ID为100
    progress->setTag(100);

    //定义一个定时器
    schedule(schedule_selector(ProgressTimer::scheduleFunc), 0.5f);

    return true;
}

void ProgressTimer::scheduleFunc(float dt)
{
    //通过进度条的ID得到进度条
    CCProgressTimer* progress = (CCProgressTimer*)getChildByTag(100);
	
    progress->setPercentage(progress->getPercentage() + 1);
	
    if (progress->getPercentage() >= 100)
	{
		unscheduleAllSelectors();
	}
}
