必须多次导入Maya.cmds，否则Maya将按钮按下按钮忘记

Question

至于某些背景，我的代码很可能是一团糟，主要是因为我一生中只有几个小时的脚本。

用于类IM创建具有所有标准行星的太阳系，也是用户输入自己的行星的选项。一切都很好，直到我尝试让用户用UI中的按钮（目前是一个丑陋的按钮，但仍然是按钮）在行星上产生行星。如果用户按下按钮，说"太阳"，那么太阳就产生了，但是只有一次，如果他决定再次产生太阳或任何其他行星，则会出现一个错误，说明该模块不包含'polycube或多球'。因此，基本上，该按钮可以工作一次，然后不再起作用。如果我从按钮以外的任何地方都打电话给它们，它可以无限期地工作。我认为，由于他不认识polycube或polysphere，所以几乎好像我没有进口maya.cmds，所以让我们尝试一下。低和看见。

基本上我的问题如下，玛雅按下按钮时会忘记其导入的库吗？我该如何解决此问题，而无需重新IMPORT MAYA.CMDS中的每个功能？

Answer 1

答案：显然是在较短版本中导入我的maya.cmds：Maya与该程序发生冲突，我应该看到了这一点。换句话说，如果我只是将maya.cmds导入CMD，就没有更多的问题。
