I'm assuming you're talking about this code here:
ClassLoader classLoader = new MinecraftClassLoader(urls, ClassLoader.getSystemClassLoader(), jarmods, files);
String nativesPath = new File(mcBinFolder, "natives").getAbsolutePath();
System.setProperty("org.lwjgl.librarypath", nativesPath);
System.setProperty("net.java.games.input.librarypath", nativesPath);
appletClass = classLoader.loadClass("net.minecraft.client.MinecraftApplet");
mcClass = classLoader.loadClass("net.minecraft.client.Minecraft");
mcField = appletClass.getDeclaredFields()[1];
return (Applet) appletClass.newInstance();
I'm changing this but obviously Minecraft.main isn't a class but a method...
Is there something else I'm meant to do?
