问题描述
我想让汽车的形状是定制的多边形（不幸的是它们必须被绘制）但它们只是显示为微小的小箭头。我不知道该怎么做以及如何制作它，以便它们显示为我绘制的汽车，面向右侧的汽车显示为右侧形状，反之亦然。这是我第一次使用 Stack Overflow，所以请耐心等待。有人知道如何提供帮助吗？我被卡住了！！

解决方法
这对 Turtle 来说令人印象深刻。我期待 Atari 2600 赛车精灵。如果他们只是左右移动，那么您可以对这些图像进行截图，将它们保存为与您的 Turtle 脚本相同的目录中的 carleft.gif 和 carright.gif，然后是 register or add the images 和 {{ 3}}。
screen .register_shape( 'carleft.gif' )
screen .register_shape( 'carright.gif' )
sprite .shape( 'carleft' )
player .shape( 'carright' )
这里有几个问题。首先是您将面向对象乌龟与功能乌龟混合在一起。也就是说，您让海龟实例 pen 执行所有动作，但您正在从尚未移动到任何地方的默认海龟 turtle 中提取多边形。
解决此问题后，您将获得汽车的蒙版图像。下面是简化代码的输出，以显示这一点：
现在我们看到下一个问题。您可以用多个彩色多边形（多个 Shape 组件）组成一个海龟光标。但是每个单独的多边形都以一种颜色呈现。所以你必须对你的汽车设计采取不同的方法。
最后，您需要考虑您绘制的形状的方向以使其与海龟同步，并确保其质心在 (0,0) 处，以便它以 left() 干净地转动和right()。

虽然 GIF 图像是另一种选择，但它们不会像多边形一样转动——无论方向如何，海龟都会始终显示相同的图像。但是对于多边形，海龟会毫不费力地适当转动。
