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.");
}
}
