cocos2d-x制作弹出层（Layer）

//1.点击后直接在当前页面添加Layer

auto layer = SetLayer::create();
this->addChild(layer);

2.设置弹窗界面SetLayer.h

#ifndef __SET_LAYER_H__
#define __SET_LAYER_H__

#include "cocos2d.h"
#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"
using namespace cocos2d::ui;

class SetLayer : public cocos2d::Layer
{
public:
    virtual bool init();
    CREATE_FUNC(SetLayer);

private:
    ImageView* Image_back;
    Layout* Panel_1;
    void closeLayerTouch(cocos2d::Ref *pSender,Widget::TouchEventType type);
    void close(Node* pSender);

};

#endif // __SET_LAYER_H__

设置弹窗界面SetLayer.cpp

#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"
#include "SetLayer.h"

USING_NS_CC;
using namespace cocostudio::timeline;
using namespace cocos2d::ui;

bool SetLayer::init()
{
    //////////////////////////////
    // 1. super init first
    if (!Layer::init())
    {

    }

    auto rootNode = CSLoader::createNode("SetLayer.csb");
    Panel_1 = (cocos2d::ui::Layout*)rootNode->getChildByName("Panel_1");
    auto director = Director::getInstance();
    //1.真机可视区域
    Rect vidiableRect = director->getOpenGLView()->getVisibleRect();
    Panel_1->setAnchorPoint(Vec2(0.5,0.5));
    //居中
    Panel_1->setPosition(Vec2(vidiableRect.origin.x+ vidiableRect.size.width/2,vidiableRect.origin.y+ vidiableRect.size.height/2));

    //2.关闭按钮
    Image_back = (ImageView*)Helper::seekWidgetByName(Panel_1,"Image_back");

            auto seq = Sequence::create(ScaleTo::create(0.2,0),CallFuncN::create(CC_CALLBACK_1(SetLayer::close,this)),NULL);
            Panel_1->runAction(seq);
