Java 游戏中的延迟
我正在用 Java 编写一个游戏。而且，哦，奇怪的是，我遇到了性能问题。我对油漆本身进行了基准测试 - 在 3 毫秒内完成 1000 次循环。游戏逻辑甚至低于此。到目前为止，一切都很好。但我仍然遇到一个恼人的滞后：滚动时、缩放时、单击时。当我放大并放置更多对象时，问题会变得更糟。但是，即使我将这幅画循环播放 1000 次，延迟也或多或少保持不变，所以不可能是这样。 我尝试将循环放入任务中 - 仍然相同。我尝试在绘画之间暂停任务 - 还是一样。 动画运行如丝般流畅（因为帧速率稳定且高，这是有道理的）。那么我到底如何以有序的方式组织输入呢？把它们全部放在一个单独的线程中？ 任何意见都将不胜感激！
I'm writing a game in Java. And, oh wonder, i have performance issues. I benchmarked the paint itself - 1000 cycles in 3 ms tops. The game logic is even below that. So far, so good. But i still encounter an annoying lag: When scrolling, when zooming, when clicking. The problems get worse when i zoom in and more objects are placed. But still - even when I loop the painting a 1000 times the lags stays more or less the same, so that cant be it.
I tried putting the loop in a task - still the same. I tried pausing the task in between paints - still the same.
Animations run as smooth as silk (since the framerate is stable and high, that makes sense). So how on earth do i organize the inputs in an orderly fashion? Put them all in a seperate thread?
Any input would and will be greatly appreciated!

听起来您好像直接在正在完成 UI 更新的 Swing 事件调度线程上使用侦听器回调。您应该使用命令队列，并在调用回调时将事件放入队列中，根据命令的性质，然后在与 EDT 无关的主游戏更新循环中使用它。
It sounds like you're using listener callbacks directly on the Swing Event Dispatch Thread, where the UI updates are being done. You should use a command queue, and put events on the queue when a callback is invoked, with the nature of the command, then you use this in the main game update loop that has nothing to do with the EDT.
