我遇到的问题是,我目前正在使用Java来解决JavaFX和图形问题,我仍然认为自己是业余爱好者,我正在制作一个小像素游戏,以提高我的知识和经验图形。我想在几张图像之间交替,只是为了模拟我所创建的像素字符的“反弹”,只是为了给程序添加一些活力,但我在弄清楚如何做到这一点时遇到了很多麻烦,我花了很长时间试图找到解决我的具体问题无济于事。我将非常感谢你能给予的任何帮助,如果你有这样的帮助,请提示我改进我的代码以及我正在犯的错误。感谢您的时间。对不起,如果我错误地粘贴了代码,那么第一个计时器。

答案 0 :(得分:0)
可能的错误可能是,在构建图像时,将file:
放在文件名之前。这可以通过在创建图像后添加这行代码来证明。
System.out.println(pixelScene1.isError());
即使文件存在,也会返回true。尝试删除第37,39和39行所见的file
。
