PyQt5 – 彩色游戏

在这篇文章中，我们将看到如何使用PyQt5创建一个颜色游戏。在这个游戏中，用户必须通过说出给定单词的颜色名称来获得最大的分数，为了迷惑玩家，文本将采用不同的颜色名称。下面是颜色游戏的样子

GUI实施步骤：

1.创建一个标题标签，显示游戏的名称，设置其特征，如对齐颜色等。

2.创建一个指令标签来告诉用户指令

3.创建一个按钮来启动/重置游戏

4.创建标签以显示分数

5.创建一个行编辑来获取用户的输入

6.创建一个标签用于倒数30秒

后端实施步骤：

1.创建开始标志、颜色列表、计数器值变量和分数值变量

2.创建一个定时器对象，在一秒钟后调用一个方法

3.在定时器方法中检查启动标志是否为真，将计数器值设置为计数器标签，并递减计数值

4.检查计数器变量是否等于零，然后使启动标志为假，并使行的编辑功能失效

5.为启动按钮添加动作

6.在开始按钮的动作中，将开始值设为真，将计数值设为30，并清除行的编辑文本

7.从颜色列表中获取随机选择，并将该颜色设置为颜色标签

8.再次从列表中获得随机选择，并将该文本设置为标签

9.当按下回车键时，为行编辑添加动作

10.在行编辑的动作中，检查输入的文本与随机选择是否匹配，如果匹配，则增加分数值，用另一个随机值改变颜色标签的颜色和文本。

以下是实现方法
