我正在尝试将我的LWJGL应用程序移植到Applet上以便在线播放，但是，我无法弄清楚如何为本地人提供正确的路径。
这是.java Applet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()
{
}
}
下面是HTML代码：

在桌面应用程序和Applet中执行时，Java运行时本机库的定位方式存在显着差异。因为Applet被捆绑并传输以在客户端浏览器中运行，所以必须包含它所需的大多数依赖项，尤其是它引用的本机库。幸运的是，LWJGL提供了一个帮助程序类，用于管理部署为applet的应用程序。
详细了解LWJGL AppletLoader以及如何将其合并到您的应用中。

您的applet标记的头部错误，应该如下
<applet code="org.lwjgl.util.applet.AppletLoader"
archive="lwjgl_util_applet.jar"
codebase="."
width="640" height="512">
同样应将idk.jar添加到al_jars参数中。其余的看起来是正确的。
