c++ - 如何使用cocos2d-x v3.2 在全局类(helloworld.h) 中声明标签？

Question

我正在使用 cocos2d-x v3.2 (c++) 创建一个 2d 平台游戏，我正在使用标签。

cocos2d-x v3.0 (c++)声明为 cocos2d::LabelTTF* currentScore;

cocos2d-x v2.2.2 (c++)声明为 cocos2d::CCLabelTTF* currentScore;

cocos2d-x v3.2(C++)如何在全局类(helloworld.h)中声明标签我试过了

Hello World .h

class HelloWorld : public cocos2d::LayerColor

{
public:
  virtual bool init();
cocos2d::LabelTTF* currentScore;   //semantic issue(LabelTTF deprecared)
};

    #endif

Hello World .cpp

bool HelloWorld::init()
{
currentScore = LabelTTF::create("", "Arial", 40);  //semantic issue(LabelTTF deprecared)

    // position the label on the center of the screen
    currentScore->setPosition(Vec2(origin.x + visibleSize.width/2,
                            origin.y + visibleSize.height - currentScore->getContentSize().height));

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

    char buffer[10];
    sprintf(buffer, "%04i",0);
    currentScore->setString(std::string(buffer));
}

再试一次

Hello World .cpp

 bool HelloWorld::init()
    {

    Auto currentScore = LabelTTF::create("", "Arial", 40);
    //position the label on the center of the screen
        currentScore->setPosition(Vec2(origin.x + visibleSize.width/2,
                                origin.y + visibleSize.height - currentScore->getContentSize().height));

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

它工作但不能“Auto currentScore；”在全局类(HelloWorld.h)中声明

Answer 1

在.h文件中

Label *autolabel4;

在.cpp 中

//autolabel4 = Label::create();无法改善标签大小和字体

autolabel4 = Label::createWithSystemFont("hello","Arial.ttf",40);
  autolabel4->setString("name isss :");
  autolabel4->setColor(Color3B(23,33,44));
  autolabel4->setPosition(Point(origin.x+ visibleSize.width/2,
                              origin.y + visibleSize.height - 400));
      this->addChild(autolabel4, 1);
