有没有办法使用 BMP 图像加载自定义字体..
我在网上看到了 Microsoft 提供的解决方案，但在尝试运行该解决方案时，我一直遇到内容加载异常。
这似乎曾经适用于 XNA，但可能不再适用于 Monogame。
我想要自己的自定义字体，因为这种字体不会预装在客户的计算机上。
我已经看过来自 SpriteFont Converter 的 XNB 文件，但这不是我想要的解决方案。
任何帮助将不胜感激，谢谢

经过长时间的研究，我最终在网上找到了解决方案。这是教程的链接:http://www.craftworkgames.com/blog/tutorial-bmfont-rendering-with-monogame/
此方法要求您下载名为 bmFont 的软件:http://www.angelcode.com/products/bmfont/
使用此软件，您将收到作为 2 个文件的字体输出:
- .fnt文件，用于纹理中的图案
- .png文件，即实际字符。
为了使这些文件与您的 monoproject 一起工作(我想也可以与 XNA 一起工作)，您需要将此类添加到您的项目中(注意:您将需要更改命名空间) :

return file;

}
}
为了以面向对象的方式实现它，我稍微修改了这个类。以下是如何在主 Game.cs 文件中将此类与自定义字体一起使用。
对于这个例子，我有文件 time_0.png 和 time.fnt 由软件 BmFonts 生成。它们是我想使用的 Avenir Next Condensed 字体的结果。
public class Game1 : Game
{
// Graphic variables used for the game to work
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
BmFont fontTime;
public Game1 ()
{
graphics = new GraphicsDeviceManager (this);
Content.RootDirectory = "Content";
graphics.IsFullScreen = true;
}
protected override void LoadContent ()
{
// Create a new SpriteBatch, which can be used to draw textures.
spriteBatch = new SpriteBatch (GraphicsDevice);
fontTime = new BmFont ("time.fnt", "time_0.png", this.Content);
}
protected override void Draw (GameTime gameTime)
{
graphics.GraphicsDevice.Clear (Color.CornflowerBlue);
spriteBatch.Begin();
fontTime.draw (DateTime.Now.ToString("HH mm"), new Vector2 (100, 50)), spriteBatch);
spriteBatch.End();
base.Draw (gameTime);
}
}
给你。现在你应该一切都好，看看它为你自己工作。 困难的部分是调整字体大小，因为您需要为所需的每种字体大小生成一个文件。
尽管如此，这种技术为您提供了直接嵌入字体的可能性，而不需要最终用户在他的计算机上安装它(这曾经是崩溃的)。
