java - 从 eclipse 导出我的 Java 游戏，运行时出现错误

Question

我在 eclipse 中制作了一个 Java 游戏，当我运行可执行文件 .jar 时，它会启动，加载屏幕也会启动，但随后会停止并挂起。我使用命令行运行它:“Java -jar filename.jar”，当加载屏幕停止时，它会显示错误。这是 cmd 显示的内容:

编辑 - 我查看了 .jar 文件，它包含它需要的所有字体和 Sprite ，并且当我导出它时，Eclipse 将所需的所有库打包到 .jar 中。

Answer 1

看起来像这个文件:

.\resources\Fonts\tight_pixel.ttf

不包含在您的 jar 中。当您从 Eclipse 执行项目时，它可能在您的类路径中可用，因此您没有注意到它。
