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：

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

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：
