Question

问题：我有一个程序涉及从一侧到另一侧移动一个栏（如砖块）。问题是它在Eclipse内部运行时的速度与导出到桌面时的速度不同。

研究：

阅读本文时，我认为我可能无法正确创建delta值，这可以解释为什么它以不同的速度运行。 my computer is carrying out java programs which i have created to fast [closed]

阅读这篇文章后，我发现可能 Eclipse编译器只是更快，这可能导致速度差异。 Application runs faster in eclipse

    // run() is being ran with a while(true) game loop
    public void run(Input input)
    {
         init();
         // Ran at 60 FPS
         if(fps.tick())
              render();
         // Ran as fast as possible
         update(input);
    }

    private void render()
    {
         start = System.nanoTime();     

         if(render.getGraphics() != null)
         {
             Graphics g = render.getBS().getDrawGraphics();
             g.drawImage(new BufferedImage(Reference.WIDTH*Reference.SCALE, Reference.HEIGHT*Reference.SCALE, 
                BufferedImage.TYPE_INT_RGB), 0,0, AppGameContainer.canvas);
             activeState.render(render.getGraphics(), AppGameContainer.canvas);
             render.getGraphics().dispose();
             render.getBS().show();
         }
         end = System.nanoTime();

         // Time in ms
         delta =  (end-start)/1000000.0;
    }

    // run() is being ran with a while(true) game loop
    public void run(Input input)
    {
         start = System.nanoTime();
         init();
         // Ran at 60 FPS
         if(fps.tick())
              render();
         // Ran as fast as possible
         update(input);
         end = System.nanoTime();

         // Time in ms
         delta =  (end-start)/1000000.0;
    }

    private void render()
    {       
         if(render.getGraphics() != null)
         {
             Graphics g = render.getBS().getDrawGraphics();
             g.drawImage(new BufferedImage(Reference.WIDTH*Reference.SCALE, Reference.HEIGHT*Reference.SCALE, 
                BufferedImage.TYPE_INT_RGB), 0,0, AppGameContainer.canvas);
             activeState.render(render.getGraphics(), AppGameContainer.canvas);
             render.getGraphics().dispose();
             render.getBS().show();
         }
    }

Eclipse程序比导出后运行得更快
