unity将图片转换成字体的方法

本文实例为大家分享了unity利用图片来生成字体的具体代码，供大家参考，具体内容如下

开发中，可能会用到需要将图片转换成字体的需求。

bmfont 插件 导入图片

然后生成 .fnt 和 .png 两个文件 （文件格式可以在设置中更改）
将这两个文件导入unity 将png 切割成精灵
创建材质、将贴图拖上去。
创建字体、将材质拖上去。

数据怎么算出来的公式百度上面有，此处略去。也可以利用代码来生成

using unityengine;
using system.collections;
using system;
using system.xml;

public class customfontimportor : monobehaviour {

  public font font;
  public textasset textasset;


  void awake()
  {
    if (font == null || textasset == null)
    {
      debug.logerror("请设置font和textasset.");
      return;
    }

    xmldocument xmldocument = new xmldocument();
    xmldocument.loadxml(textasset.text);


    int totalwidth = convert.toint32(xmldocument["font"]["common"].attributes["scalew"].innertext);
    int totalheight = convert.toint32(xmldocument["font"]["common"].attributes["scaleh"].innertext);

    xmlelement xml = xmldocument["font"]["chars"];
    arraylist characterinfolist = new arraylist();


    for (int i = 0; i < xml.childnodes.count; ++i)
    {
      xmlnode node = xml.childnodes[i];
      if (node.attributes == null)
      {
        continue;
      }
      int index = convert.toint32(node.attributes["id"].innertext);
      int x = convert.toint32(node.attributes["x"].innertext);
      int y = convert.toint32(node.attributes["y"].innertext);
      int width = convert.toint32(node.attributes["width"].innertext);
      int height = convert.toint32(node.attributes["height"].innertext);
      int xoffset = convert.toint32(node.attributes["xoffset"].innertext);
      int yoffset = convert.toint32(node.attributes["yoffset"].innertext);
      int xadvance = convert.toint32(node.attributes["xadvance"].innertext);

      characterinfo info = new characterinfo();
      rect uv = new rect();
      uv.x = (float)x / totalwidth;
      uv.y = (float)(totalheight - y - height) / totalheight;
      uv.width = (float)width / totalwidth;
      uv.height = (float)height / totalheight;


      info.index = index;
      info.uvbottomleft = new vector2(uv.xmin, uv.ymin);
      info.uvbottomright = new vector2(uv.xmax, uv.ymin);
      info.uvtopleft = new vector2(uv.xmin, uv.ymax);
      info.uvtopright = new vector2(uv.xmax, uv.ymax);
      info.minx = xoffset;
      info.maxx = xoffset + width;
      info.miny = -yoffset - height;
      info.maxy = -yoffset;
      info.advance = xadvance;
      info.glyphwidth = width;
      info.glyphheight = height;


      characterinfolist.add(info);
    }
    font.characterinfo = characterinfolist.toarray(typeof(characterinfo)) as characterinfo[];


    debug.log("生成成功.");
  }
}
