本文介绍如何在Cocos2d-x中实现带有进度条的加载界面，包括添加进度背景图、创建并控制LoadingBar的进度，以及通过调度器调整进度速度等关键步骤。此外还展示了如何根据不同条件跳转至不同的场景。

先看实现的效果图
这里写图片描述
首先在头文件添加

#include "ui/CocosGUI.h"

在init方法编辑相应的代码
这里写图片描述
添加进度背景图

auto loadbg = Sprite::create("jindutiaoBG.png");
	loadbg->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y - 200));
	this->addChild(loadbg,2);

在者创建LoadingBar 使用schedule调度器控制进度速度

auto lb = ui::LoadingBar::create("jindutiao.png");
	lb->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y-200));
	lb->setDirection(ui::LoadingBar::Direction::LEFT);
	lb->setPercent(0);
	addChild(lb, 3, 3);//同时设置Tag值为1
	schedule(CC_CALLBACK_1(Loading::LoadingBar, this), "LoadingBar");
	Loading::count = 0;

//加载进度条的进度
void Loading::LoadingBar(float dt){
	count++;
	CCLOG("ccccccccccc");
	auto size = Director::getInstance()->getVisibleSize();
	auto lb = dynamic_cast<class ui::LoadingBar*>(getChildByTag(3));
	//float per = lb->getPercent() + 1.0f;
	float per = count / 12 * 100;
	lb->setPercent(per);
	switch (count){
	case 2:
		CocosDenshion::SimpleAudioEngine::getInstance()->preloadBackgroundMusic("data/music/bg/a_chooselevel.mp3");
		break;
	case 12:
		unschedule("LoadingBar");
		CocosDenshion::SimpleAudioEngine::getInstance()->preloadBackgroundMusic("data/music/bg/a_yueyemusic.mp3");
		std::string docpath=FileUtils::getInstance()->getWritablePath() + "hero.txt";
		//判断文件是否存在 
		if (!FileUtils::getInstance()->isFileExist(docpath)){
			//不存在则到这个场景
			CCLOG("aaaaaaaaaaaaa");
			auto callf = CallFunc::create([this](){
				//Director::getInstance()->replaceScene(StartLayer::createScene());
				Director::getInstance()->replaceScene(TransitionPageTurn::create(2, StartLayer::createScene(), false));
			});
			auto seq = Sequence::create(DelayTime::create(1.1), callf, NULL);
			this->runAction(seq);
		}
		else{
			CCLOG("bbbbbbbbbbb");
			auto callf = CallFunc::create([this](){
				Director::getInstance()->replaceScene(TransitionPageTurn::create(2, MainLayer::createScene(), false));
			});
			auto seq = Sequence::create(DelayTime::create(1.1), callf, NULL);
			this->runAction(seq);
		}
		break;
	}
}
