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

Cocos2d-X中的ProgressTimer-LMLPHP

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:

ProgressTimer实现旋转效果的进度条

程序代码:

#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();
}
