我目前正在尝试用Java编写井字游戏，该游戏可以在网络上玩。我正在使用Java中的套接字编程，而对于UI，我正在使用JavaFX。启动服务器和2个客户端后，客户端将连接到服务器，将玩家配对并创建游戏。尝试执行实际的Tic Tac Toe游戏时，GUI卡住了。我相信这可能与线程有关，但是经过无数小时尝试不同的解决方案后，我仍无法弄清楚。
以下是该问题的视频 https://www.youtube.com/watch?v=dCIxRkGJlCI&t=2s
我的GitHub存储库： https://github.com/Stinny/Tic-Tac-Toe
我认为该问题存在于TicTacToeController.java类中
任何信息将不胜感激！
