cocos2dx3.2图片以及按钮变灰

之前在3.0上可以 正常在win32上显示，真是好不容易，什么坐标偏移之类的都花了不少时间到网上去找资料，可是因为项目问题，换了3.2，结果崩溃了。下面先贴上在3.2下win32的解决办法。

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    /////////////////////////////
    // 2. add a menu item with "X" image, which is clicked to quit the program
    //    you may modify it.

    // add a "close" icon to exit the progress. it's an autorelease object
    auto closeItem = MenuItemImage::create(
                                           "CloseNormal.png",
                                           "CloseSelected.png",
                                           CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
    
	closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 ,
                                origin.y + closeItem->getContentSize().height/2));

    // create menu, it's an autorelease object
    auto menu = Menu::create(closeItem, NULL);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu, 1);

    /////////////////////////////
    // 3. add your codes below...

    // add a label shows "Hello World"
    // create and initialize a label
    
    auto label = LabelTTF::create("Hello World", "Arial", 24);
    
    // position the label on the center of the screen
    label->setPosition(Vec2(origin.x + visibleSize.width/2,
                            origin.y + visibleSize.height - label->getContentSize().height));

    // add the label as a child to this layer
    this->addChild(label, 1);

    // add "HelloWorld" splash screen"
    auto sprite = Sprite::create("HelloWorld.png");

    // position the sprite on the center of the screen
    sprite->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));
    // add the sprite as a child to this layer
    this->addChild(sprite,0);
    graySprite(sprite);

	auto button =  Button::create("HelloWorld.png");
	button->setPosition(Vec2(visibleSize.width/4 + origin.x, visibleSize.height/2 + origin.y));
	this->addChild(button);
	//button->getVirtualRenderer()
	graySprite(static_cast(button->getVirtualRenderer()));
    return true;
}

void HelloWorld::graySprite(cocos2d::Sprite * sprite) 
{  
	if(sprite)  
	{  
		GLProgram * p = new GLProgram();  
		p->initWithFilenames("gray.vsh", "gray.fsh");  
		p->bindAttribLocation(GLProgram::ATTRIBUTE_NAME_POSITION, GLProgram::VERTEX_ATTRIB_POSITION);  
		p->bindAttribLocation(GLProgram::ATTRIBUTE_NAME_COLOR, GLProgram::VERTEX_ATTRIB_COLOR);  
		p->bindAttribLocation(GLProgram::ATTRIBUTE_NAME_TEX_COORD, GLProgram::VERTEX_ATTRIB_TEX_COORDS);  
		p->link();  
		p->updateUniforms();  
		sprite->setShaderProgram(p);  
	}  
}

迟点再贴Lua的代码，包括变灰以及还原。

两个文件，差点忘了。
