我一直在用PyQt5(Python(设计一款基于GUI的国际象棋游戏。由于它是不完整的，所以存在一些问题。但最大的问题是，每次移动后，GUI中的时间滞后都会增加。经过一段特定的时间(比如移动8(后，GUI将几乎停止工作。请帮忙。代码如下：

谢谢。
它会随着时间的推移而滞后，因为每次移动后，您都会再次连接play_move和initiate_move中所有64个按钮的clicked信号。。连接信号的插槽功能将在事件循环中执行，导致游戏延迟
如果你再次连接信号，并不意味着它会断开之前的信号，而是添加其他信号，所以在移动一两次后，每次移动都会导致64个信号再次连接，移动5到6次后，每个信号都会连接5000多个插槽。。
如果信号连接到插槽，它将保持连接，直到它被破坏或明确断开连接。。
因此，相应地修改您的代码，使信号不必再次连接或在再次连接之前断开信号(它可以工作，但不推荐(
