说明

引擎版本：cocos2d-x 3.4 编译器：visual studio 2013 UI编辑器：Cocos Studio v1.6.0.0

Label（cocos/2d模块下）

常用API如下：

• createWithSystemFont
  

    
    

     
     

     
     

     
     

     
     

     
     

     
     

    
    
/** Creates a label with an initial string,font[font name or font file],font size,dimension in points,horizontal alignment and vertical alignment. * @warning It will generate texture by the platform-dependent code */static Label* createWithSystemFont(const std::string& text,  font float fontSize Size dimensions =ZERO TextHAlignment hAlignment  TextHAlignmentLEFT TextVAlignment vAlignment  TextVAlignmentTOP);

• createWithTTF
  

     
     

      
      

      
      

      
      

      
      

      
      

      
      

      
      

     
     
* @warning Not support font name.* @warning Cache textures for each different font size or font file.*/ Label  createWithTTF fontFile);

• createWithBMFont
  

需要一个图片文件（*.png）和一个字体文件（*.fnt）

/* Creates a label with an FNT file,an initial string,horizontal alignment,max line width and the offset of image*/ createWithBMFont bmfontFilePath alignment int maxlinewidth 0 Vec2 imageOffset );

//可以得到相应下标的Sprite，可以单独设置virtual Sprite getLetter(int lettetIndex

• createWithCharMap
  

//@startCharMap 为ANSIC码，即'0'为48 createWithCharMap charMapFile itemWidth itemHeight startCharMap);//利用纹理创建(Texture2D texture//eg:Texture2D texture TextureCachegetInstance()->addImage("labelatlasimg.png");Label label createWithCharMap(texture2432 '0'//.plist文件创建 plistFile .plist文件格式如下：

<?xml version="1.0" encoding"UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"><dict><key>version</key> <!-- plist版本 --><integer>1</integer>textureFilename<!-- 字符图片资源: digit.png --><string>labelatlasimg.png</string>itemWidth<!-- 每个字符的宽: 24 -->24itemHeight<!-- 每个字符的高: 32 -->32firstChar<!-- 起始字符 : '0' -->48</dict></plist>
