在Python中使用 PyQt5 的井字游戏
在本文中，我们将了解如何使用PyQt5创建井字游戏。 Tic-tac-toe、noughts 和 crosss，或 Xs 和 Os 是一种纸笔游戏，适用于 X 和 O 两个玩家，他们轮流在 3×3 网格中标记空间。成功将三个标记放置在水平、垂直或对角线行中的玩家为获胜者。
以下是井字游戏的外观：
GUI implementation steps :
1. Create a list of push buttons
2. Arrange them in 3×3 order and add font to them
3. Create a label below the push buttons that tells the result
4. Set alignment and font to the label
5. Add another push button for reset the game at the bottom
Back end implementation steps :
1. Create two variable to know whose chance is and to know how many chances are completed
2. Add same action to the list of buttons such that each buttons should call the same action
3. Inside the action method get the button by whom method is called using sender method
4. Set the text to the button according to the chance and make it disabled so that it can’t be pressed again and call the who_wins method
5. Set text according to the answer returned by the who_wins method
6. Inside the who_wins method check if rows, columns and diagonals are crossed or not.
7. If someone won the match set the text to the label and make all the buttons disabled
8. Add action to the reset button
9. Inside the reset button action make the variable value set to the starting value and make all the push button enabled and make the label and button text to blank.
