为什么我的字体不能渲染？ [英] Why doesn't my font render?
问题描述
这里是源代码，它在左上角呈现两个文本字段，在中间呈现两个白色的形状。
包装游戏;如果我使用默认的字体，

$ b 解决方案当我将一个带有该名称的fnt添加到我的类路径中时，您的示例适用于我。我正在使用maven，并且只是把.fnt放到了src / main / resources中。在指定字体名称时，Nifty希望它可以在相对于当前目录的文件系统中或在类路径的根目录中作为类路径资源访问。
没什么特别的。您可以检查加载资源的类 here
但是，.fnt文件可能存在问题。你是如何创建该文件的？通常你需要相应的.png或.tga与.fnt处于相同的位置，而.fnt里面有一个对Nifty读取的实际图像文件的引用。也许Nifty可以找到.fnt，但不是实际的图像资源？
I've been using nifty GUI with lwjgl, and its been working great, but I can't figure out how to get it to use fonts I've provided it; it only seems to be able to render the default fonts. I've added the folder with my .fnt files to the runtime classpath (via eclipse), and this makes it so that no "resource not found" exception occurs, but when I run the program, any text fields using my font don't render.
Here's the source code, it renders two text fields in the upper left corner and 2 white shapes in the center. the textfield on the right won't render unless I use the default font.

解决方案 Your example works for me when I add a fnt with that name to my classpath. I'm using maven and I've just put the .fnt into src/main/resources. When you specify the font name Nifty expects it to be accessible either in the filesystem relative to the current directory OR at the root at the classpath as a classpath resource.
There is nothing special going on. You can inspect the class that loads the resources here
However, there might be a problem with your .fnt file. How did you create that file? And usually you need the corresponding .png or .tga in the same position as your .fnt AND there is a reference inside the .fnt to the actual image file which Nifty reads. Maybe Nifty can find the .fnt but not the actual image resource?
