BMFont制做美术字体

 

 

 

 

 

 

 

 

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

 

 

 

 

 

箭头所指就是咱们要获得的最终目标，在文本处字体使用它就能够了。

 

在使用 Tools -> BMFont Maker 以前得先完成如下步骤：

 

1.  
   using UnityEngine;
2.  
   using UnityEditor;
3.  
    
4.  
   public class BMFontEditor : EditorWindow
5.  
   {
6.  
   [MenuItem("Tools/BMFont Maker")]
7.  
   static public void OpenBMFontMaker()
8.  
   {
9.  
   EditorWindow.GetWindow <BMFontEditor>(false, "BMFont Maker", true).Show();
10.  
    }
11.  
     
12.  
    [SerializeField]
13.  
    private Font targetFont;
14.  
     
15.  
    [SerializeField]
16.  
    private TextAsset fntData;
17.  
     
18.  
    [SerializeField]
19.  
    private Material fontMaterial;
20.  
     
21.  
    [SerializeField]
22.  
    private Texture2D fontTexture;
23.  
     
24.  
    private BMFont bmFont = new BMFont();
25.  
     
26.  
    public BMFontEditor()
27.  
    {
28.  
    }
29.  
     
30.  
    void OnGUI()
31.  
    {
32.  
    targetFont = EditorGUILayout.ObjectField("Target Font", targetFont, typeof(Font), false) as Font;
33.  
    fntData = EditorGUILayout.ObjectField("Fnt Data", fntData, typeof(TextAsset), false) as TextAsset;
34.  
    fontMaterial = EditorGUILayout.ObjectField("Font Material", fontMaterial, typeof(Material), false) as Material;
35.  
    fontTexture = EditorGUILayout.ObjectField("Font Texture", fontTexture, typeof(Texture2D), false) as Texture2D;
36.  
     
37.  
    if (GUILayout.Button("Create BMFont"))
38.  
    {
39.  
    BMFontReader.Load(bmFont, fntData.name, fntData.bytes); //借用NGUI封装的读取类
40.  
    CharacterInfo[] characterInfo = new CharacterInfo[bmFont.glyphs.Count];
41.  
    for (int i = 0; i < bmFont.glyphs.Count; i++)
42.  
    {
43.  
    BMGlyph bmInfo = bmFont.glyphs[i];
44.  
    CharacterInfo info = new CharacterInfo();
45.  
    info.index = bmInfo.index;
46.  
    info.uv.x = (float)bmInfo.x / (float)bmFont.texWidth;
47.  
    info.uv.y = 1 - (float)bmInfo.y / (float)bmFont.texHeight;
48.  
    info.uv.width = (float)bmInfo.width / (float)bmFont.texWidth;
49.  
    info.uv.height = -1f * (float)bmInfo.height / (float)bmFont.texHeight;
50.  
    info.vert.x = 0;
51.  
    info.vert.y = -(float)bmInfo.height;
52.  
    info.vert.width = (float)bmInfo.width;
53.  
    info.vert.height = (float)bmInfo.height;
54.  
    info.width = (float)bmInfo.advance;
55.  
    characterInfo[i] = info;
56.  
    }
57.  
    targetFont.characterInfo = characterInfo;
58.  
    if (fontMaterial)
59.  
    {
60.  
    fontMaterial.mainTexture = fontTexture;
61.  
    }
62.  
    targetFont.material = fontMaterial;
63.  
    fontMaterial.shader = Shader.Find("UI/Default");//这一行很关键，若是用standard的shader，放到Android手机上，第一次加载会很慢
64.  
     
65.  
    Debug.Log("Create Font <" + targetFont.name + "> Success");
66.  
    Close();
67.  
    }
68.  
    }
69.  
    }

将这个类放入工程中，这样在 Tools 中才能够找到 BMFont Maker，它的做用是赋予字体的详细信息，因为它是借助 NGUI 来实现的工具，因此得加上 NGUI 中的如下类：
