Turtle英译过来为乌龟,不过我们介绍的不是这种动物,而是以此命名的一个绘图软件。 在python文档中介绍了Turtle本身是一款简单、易上手的绘图软件,非常适合新手进入编程的世界。 海龟绘图Turtle是Python内置模块,总之是非常简单好玩的一个库。 其动作主要有:抬笔,此后的动作只是移动画笔,画布上不会留下痕迹;落笔,只要移...

到目前为止,您一直在检查两个游戏实体之间的碰撞(在第十一章中,使用 Pygame 制作 Outdo Turtle - Snake Game UI,您检查了蛇与边界墙之间的碰撞,而在第十二章,学习角色动画、碰撞和移动中,您检查了鸟与垂直管道之间的碰撞),但本章将更加启发人,因为您将逐个检查三个游戏对象之间的碰撞,并通过创建碰撞处理程序执行...

As you can see, the starting point of the circle is the centre of the screen by default, which is not the centre of the circle. In order to get round this problem, we have to set the position by code as follows: import turtle # importing the module trtl = turtle.Turtle() #making...
