我们现在可以开始使用面向对象的原则,矢量化移动进行事件处理,旋转技术来旋转游戏中使用的图像或精灵,甚至使用我们在 turtle 模块中学到的东西。在 turtle 模块中,我们学习了如何创建对象(参见第六章,面向对象编程),这些对象可以用于在我们可能使用 Pygame 构建的游戏的基本阶段调试不同的功能。因此,我们迄今为止学到的...
Each turtle has a home position that it must reach. Each player uses a die to choose a value at random for their turn. In your program, the die is represented by a list of numbers from 1 to 6. Now that you’ve understood the logic of the game, you can go ahead and begin creatin...
