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, typeof(Font), false) as Font;
-
fntData = EditorGUILayout.ObjectField("Fnt Data", fntData, typeof(TextAsset), false) as TextAsset;
-
fontMaterial = EditorGUILayout.ObjectField("Font Material", fontMaterial, typeof(Material), false) as Material;
-
fontTexture = EditorGUILayout.ObjectField("Font Texture", fontTexture, typeof(Texture2D), false) as Texture2D;
-
-
if (GUILayout.Button("Create BMFont"))
-
{
-
BMFontReader.Load(bmFont, 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:
