我在这里有一个小问题。我想用多个立方体制成一个“蛇形”。身体也应朝同一方向移动。我能够移动一个立方体。但是我不能在一个单元上制作多个立方体。所以我的想法是用变量定义坐标，这些变量会改变它们的值-以及坐标。首先，我尝试以变量开头设置坐标或顶点，但不适用于不同的多维数据集（以后也应使用“ n”实体）。如果滚动到“ def testcube（）：”，则我尝试了构建多维数据集的其他版本。也许有人知道如何用这种方式对立方体或顶点进行编程。因为在我的情况下，我得到一个值Error（“预期的12个字节的数组，得到96个字节的数组”）。我知道我的代码不是很好，但是我是编程人员的新手。
感谢您的帮助。如果您有任何疑问，请随时提问。
