使用某些UI元素后，模拟将停止

Question

我正在处理一个正在处理的项目，我在处理这个超级烦人的bug时遇到了一些困难。所有的代码都粘贴在下面，4个类文件。

每当"；模拟速度"；滑块向上移动，然后再向下移动，模拟将停止，不会出现错误。与"；"自动"；按钮我不知道为什么会发生这种情况，我已经按照变量查看了我的代码，没有发现任何错误。

救命！

谢谢！如果代码有点乱，很抱歉：(

在主文件中，这个块依赖于这两个控件的值：

if(frameCounter == simulationSpeed && autoScrollButton.buttonActive){
k++;
frameCounter = 0;
setHeight();
}

当被跳过时(因为您更改了simulationSpeed或buttonActive(，您的frameCounter将与simulationSpeed不同步，因此块将继续被跳过。
