问题描述
我正在使用cocos2d-x v3.2(c ++)创建一个二维平台游戏,我使用的是标签。
I'm creating a 2d platform game with cocos2d-x v3.2 (c++) and i'm using label.
cocos2d-x v3.0 c ++)
声明为 cocos2d :: LabelTTF * currentScore;
cocos2d-x v3.0 (c++)declared like cocos2d::LabelTTF* currentScore;
cocos2d-x v2.2.2 c ++)
声明为 cocos2d :: CCLabelTTF * currentScore;
cocos2d-x v2.2.2 (c++)declared like cocos2d::CCLabelTTF* currentScore;
cocos2d-x v3.2 c ++)
如何在全局类(helloworld.h)中声明标签
i尝试像
cocos2d-x v3.2(c++)how to declare label in global class(helloworld.h)i have try like
HelloWorld.h
HelloWorld.h
class HelloWorld : public cocos2d::LayerColor
{
public:
virtual bool init();
cocos2d::LabelTTF* currentScore; //semantic issue(LabelTTF deprecared)
};
#endif
HelloWorld.cpp
HelloWorld.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));
}
再次尝试
HelloWorld.cpp
HelloWorld.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
。在全局类(HelloWorld.h)中声明
it working but can't "Auto currentScore;" declared in global class(HelloWorld.h)
推荐答案
在.h文件中
Label *autolabel4;
在.cpp中
// autolabel4 = Label :: create();无法提高标签大小和大小
// autolabel4 = Label::create(); can't improve label size and fount
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);
