JOGL动画问题

Question

我正在学习使用JOGL,在学习本教程时遇到了一个问题:

• https://sites.google.com/site/justinscsstuff/jogl-tutorial-1
• https://sites.google.com/site/justinscsstuff/jogl-tutorial-2
• https://sites.google.com/site/justinscsstuff/jogl-tutorial-3

在第三个教程上运行代码时,我看到了一个预期的三角形,但它没有移动.我也遇到了这个错误.

Exception in thread "main" java.lang.IllegalArgumentException: Drawable already added to animator: com.jogamp.opengl.util.Animator[started false, animating false, paused false, drawable 1, totals[dt 0, frames 0, fps 0.0], modeBits 1, init'ed true, animThread null, exclCtxThread false(null)], AWT-GLCanvas[Realized true,

在本教程的第一部分建立我的类路径的时候,我发现了jogl-all.jar和gluegen.jar,但我无法找到nativewindow.all.jar或者newt.all.jar所以我选择最接近我能找到哪些是jogl-all-natives-windows-amd64.jar与newt-natives-windows-amd64.jar(我甚至不认为我需要蝾螈,因为我认为只允许我使用除标准AWT框架之外的其他类型的框架.如果我错了,请纠正我.)这可能与问题有关吗？

在教程中,它看起来像"animator.add(canvas);" 是多余的.只是评论出来.

Animator animator = new Animator(canvas);
// animator.add(canvas);
animator.start();
