怎么使用BMFont制作美术字体，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
生成 Number.fnt、Number_0.png 两个文件，将其拖入Unity 相应位置，继续下一步
箭头所指就是我们要得到的最终目标，在文本处字体使用它就可以了。
在使用 Tools -> BMFont Maker 之前得先完成以下步骤：
using UnityEngine;
using UnityEditor;
public class BMFontEditor : EditorWindow
{
[MenuItem"Tools/BMFont Maker")]
static public void OpenBMFontMaker)
{
EditorWindow.GetWindow<BMFontEditor>false, "BMFont Maker", true).Show);
}
[SerializeField]
private Font targetFont;
[SerializeField]
private TextAsset fntData;
[SerializeField]
private Material fontMaterial;
[SerializeField]
private Texture2D fontTexture;
private BMFont bmFont = new BMFont);
public BMFontEditor)
{
}
void OnGUI)
{
targetFont = EditorGUILayout.ObjectField"Target Font", targetFont, typeofFont), false) as Font;
fntData = EditorGUILayout.ObjectField"Fnt Data", fntData, typeofTextAsset), false) as TextAsset;
fontMaterial = EditorGUILayout.ObjectField"Font Material", fontMaterial, typeofMaterial), false) as Material;
fontTexture = EditorGUILayout.ObjectField"Font Texture", fontTexture, typeofTexture2D), false) as Texture2D;
if GUILayout.Button"Create BMFont"))
{
BMFontReader.LoadbmFont, fntData.name, fntData.bytes); //借用NGUI封装的读取类
CharacterInfo[] characterInfo = new CharacterInfo[bmFont.glyphs.Count];
for int i = 0; i < bmFont.glyphs.Count; i++)
{
BMGlyph bmInfo = bmFont.glyphs[i];
CharacterInfo info = new CharacterInfo);
info.index = bmInfo.index;
info.uv.x = float)bmInfo.x / float)bmFont.texWidth;
info.uv.y = 1 - float)bmInfo.y / float)bmFont.texHeight;
info.uv.width = float)bmInfo.width / float)bmFont.texWidth;
info.uv.height = -1f * float)bmInfo.height / float)bmFont.texHeight;
info.vert.x = 0;
info.vert.y = -float)bmInfo.height;
info.vert.width = float)bmInfo.width;
info.vert.height = float)bmInfo.height;
info.width = float)bmInfo.advance;
characterInfo[i] = info;
}
targetFont.characterInfo = characterInfo;
if fontMaterial)
{
fontMaterial.mainTexture = fontTexture;
}
targetFont.material = fontMaterial;
fontMaterial.shader = Shader.Find"UI/Default");//这一行很关键，如果用standard的shader，放到Android手机上，第一次加载会很慢
Debug.Log"Create Font <" + targetFont.name + "> Success");
Close);
}
}
}
将这个类放入工程中，这样在 Tools 中才可以找到 BMFont Maker，它的作用是赋予字体的详细信息，由于它是借助 NGUI 来实现的工具，所以得加上 NGUI 中的以下类：
