【问题描述】：
我正在尝试将我的 LWJGL 应用程序移植到 Applet 以在线播放，但是，我不知道如何为本地人提供正确的路径。
这是 .java 小程序代码：
package net.foxycorndog.idk.applet;
import java.applet.Applet;
import java.awt.BorderLayout;
import java.awt.Canvas;
import net.foxycorndog.idk.Idk;
import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.Display;
public class IdkApplet extends Applet
{
Canvas drawCanvas;
Idk idk;
/** is the game loop running */
boolean running = false;
public void startLWJGL()
{
idk.start(drawCanvas);
}
/**
* Tell game loop to stop running, after which the LWJGL Display will be
* destroyed. The main thread will wait for the Display.destroy().
*/
private void stopLWJGL()
{
running = false;
try
{
idk.getGameThread().join();
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
public void start()
{
}
public void stop()
{
}
/**
* Applet Destroy method will remove the canvas, before canvas is destroyed
* it will notify stopLWJGL() to stop the main game loop and to destroy the
* Display
*/
public void destroy()
{
super.destroy();
System.exit(0);
}
public void init()
{
Idk.init();
idk = new Idk();
setLayout(new BorderLayout());
try
{
drawCanvas = new Canvas()
{
public final void addNotify()
{
super.addNotify();
startLWJGL();
}
public final void removeNotify()
{
stopLWJGL();
super.removeNotify();
}
};
setSize(640, 512);
drawCanvas.setSize(getWidth(), getHeight());
add(drawCanvas);
drawCanvas.setFocusable(true);
drawCanvas.requestFocus();
drawCanvas.setIgnoreRepaint(true);
setVisible(true);
}
catch (Exception e)
{
System.err.println(e);
throw new RuntimeException("Unable to create display");
}
}
protected void initGL()
{
}
}
HTML 代码如下：

这是错误输出：

【问题讨论】：
-
你在使用LWJGL AppletLoader吗？
-
不，我不是。现在我是并且它正在工作，有点。我无法检索我的资源。 “java.lang.RuntimeException：找不到资源：org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoader.java:69) 上的 res/images/font/pixel.ttf ...”有什么想法吗？
-
我在下面的答案中发表了评论，请随时接受，因为它似乎已经解决了您的（初始）问题。对于资源加载问题，请发布一个单独的问题，并在其中包含您的资源加载代码和存储它们的项目结构。
