cocos2dx 3.x c++实现一个win32自定义按钮

由于cocos2dx的按钮创建过于复杂还不支持win32悬停功能

所以考虑自己封装一个

myButton.h

#pragma once   

#pragma execution_character_set("utf-8")    

#include"cocos2d.h"

#include"游戏数据.h"

using namespace std;

using namespace cocos2d;

class myButton:public Sprite

{

public:

    myButton(string normalPath, string onPath, string downPath, Node* fatherNode, Point position);//普通myButton构造

    //按下透明myButton构造

    //音效myButton构造

    std::function<void()> myButtonCall;

    virtual ~myButton();

private:

    string normalPath;

    string onPath;

    string downPath;

    Rect rect;

    Node* fatherNode;

    Point position;

    int mouseState;//0松开 1按下 

    int textureState;//0正常 1悬停

    void update(float dt);

    void setNoormalTexture();

    void setOnTexture();

    void setDownTexture();

};

myButton.cpp 

#include "myButton.h"

myButton::myButton(string normalPath,string onPath, string downPath,Node* fatherNode, Point position)

{

    this->normalPath = normalPath;

    this->onPath = onPath;

    this->downPath = downPath;

    this->fatherNode = fatherNode;

    this->position = position;

    mouseState = 0;

    textureState = 0;

   initWithFile(normalPath);

    autorelease();

    setPosition(this->position);

    fatherNode->addChild(this, 10);

    auto fatherNodeRect = fatherNode->getBoundingBox();

    rect = this->getBoundingBox();

    rect.origin.x = rect.origin.x + fatherNodeRect.origin.x;

    rect.origin.y = rect.origin.y + fatherNodeRect.origin.y;

    auto listener = EventListenerTouchOneByOne::create();

    listener->setSwallowTouches(true);

    listener->onTouchBegan = [=](Touch* touch, Event* event)

    {

        Point touchPosition = Director::getInstance()->convertToGL(touch->getLocationInView());

        if (rect.containsPoint(touchPosition))

        {

            mouseState = 1;

            setDownTexture();

            return true;

        }

        return false;

    };

    listener->onTouchMoved = [=](Touch* touch, Event* event)

    {

        Point touchPosition = Director::getInstance()->convertToGL(touch->getLocationInView());

        if (rect.containsPoint(touchPosition))

        {

            setDownTexture();

        }

        else

        {

            setNoormalTexture();

        }

    };

    listener->onTouchEnded = [=](Touch* touch, Event* event)

    {

        Point touchPosition = Director::getInstance()->convertToGL(touch->getLocationInView());

        if (rect.containsPoint(touchPosition))

        {

            myButtonCall();

        }

        mouseState = 0;

        textureState = 0;

        setNoormalTexture();

    };

    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);

    this->scheduleUpdate();//开启定时器

}

void myButton::update(float dt)

{

    if (rect.containsPoint(游戏设置数据类::游戏设置数据.当前鼠标坐标) && mouseState == 0 && textureState == 0)

    {

        textureState = 1;

        setOnTexture();

    }

    if (rect.containsPoint(游戏设置数据类::游戏设置数据.当前鼠标坐标) == false && textureState == 1)

    {

        textureState = 0;

        setNoormalTexture();

    }

}

void myButton::setNoormalTexture()

{

    log("setNoormalTexture");

    setTexture(normalPath);

}

void myButton::setOnTexture()

{

    log("setOnTexture");

    setTexture(onPath);

}

void myButton::setDownTexture()

{

    log("setDownTexture");

    setTexture(downPath);

}

myButton::~myButton()

{

}

创建过程

首先创建鼠标监听器 监控鼠标位置 因为要实现悬停功能 鼠标的坐标自己定义吧  

    auto listenerMouse = EventListenerMouse::create();

    listenerMouse->onMouseMove = [&](EventMouse* event) {

        游戏设置数据类::游戏设置数据.当前鼠标坐标.x = event->getCursorX();

        游戏设置数据类::游戏设置数据.当前鼠标坐标.y = event->getCursorY();

        //log("%f,%f", 游戏设置数据类::游戏设置数据.当前鼠标坐标.x, 游戏设置数据类::游戏设置数据.当前鼠标坐标.y);

        //鼠标指针->setPosition(当前鼠标坐标);

    };

    _eventDispatcher->addEventListenerWithFixedPriority(listenerMouse, 1); 

auto myButton1 = new myButton(

        "picture/ui/biaoti/start1.png",

        "picture/ui/biaoti/start2.png",

        "picture/ui/biaoti/start3.png",

        this, ccp(200, 300));

    myButton1->myButtonCall = [=]()

    {

        log("我的按钮触发了");

    };

可以在此基础上继续拓展其他功能 

 大家有什么意见欢迎评论。
