Question

我使用cocos2d-x-3.3beta0使用Text类创建文本。

Text* MessageText = Text::create(message, FONT, FONT_SIZE);

我已设置文字区域的大小

MessageText ->setTextAreaSize(Size(100,150));

现在我要为文本区域着色，这是文本的背景。有没有办法做到这一点？

UIText中没有背景颜色属性。您可以对UIText进行子类化，并在其后面添加一个Layout小部件以用作背景。

TextWithBackground* TextWithBackground::create()

    _background = Layout::create();

    return true;

void TextWithBackground::setString(const std::string& text)

void TextWithBackground::setBackgroundColor(const cocos2d::Color3B &color)
{
    _background->setBackGroundColor(Color3B::RED);
    _background->setContentSize(getContentSize());
}

现在你有了setBackground方法。

TextWithBackground *MessageText = TextWithBackground::create();
MessageText->setBackgroundColor(Color3B::YELLOW);
MessageText->setString("Text with a background ");
addChild(MessageText);

Text *myTexxtt = Text::create("Hyee Shaq", "Marker Felt.ttf", 100);
myTexxtt->setPosition(Point(WinSize.width/2,WinSize.height/2));
myTexxtt->setColor(Color3B::RED);
this->addChild(myTexxtt,10);
