这不是完整的代码,因为我不想给一个无用的东西。因此,我的问题是:
如果我运行此代码,按钮将不会显示在帧中。但是如果我在Run.class中注释game.loop()
,窗口就会显示该按钮。我不明白为什么?
我已经试了几天想弄明白。我需要一些帮助。恐怕我一个人无法发现。要想通过运行一个较长的进程来避免阻塞,您可以使用swing,它可以为您处理“循环”:
ActionListener animate = e -> {
game.oneFrame();
panel.repaint();
};
timer = new Timer(50, animate);
timer.start();
public void oneFrame(){
//update what is needed for one "frame"
}
有关mcve后的更多帮助。1)不要阻止EDT(事件调度线程)。发生这种情况时,GUI将“冻结”。有关详细信息和修复方法,请参阅。2) “这不是完整的代码,因为我不想给出无用的东西。”为了更快地获得更好的帮助,请添加or。
