用于在3ds Max中选择对象名称的MaxScript

Question

大家好，Stack Overflow成员！ 首先，感谢您花费时间阅读此问题。

我正在学习Maxscript，所以我可以做一些快速而复杂的面部装备。 我的脚本完成了99％。 唯一的问题是，现在脚本已对要装配的目标对象的名称进行了硬编码（在下面的代码中为“ MYOBJECT”）。 无需在MaxScript中右键单击对象的名称，我想创建一个函数，该函数将打开一个对话框窗口，要求我单击目标面部，然后在用户单击目标对象后单击我的代码会执行已经可以完成的工作，但是使用所选的对象名称而不是硬编码名称。

我的代码在下面。 非常感谢您的帮助！

如果您有UI，请在运行之前使用pickButton并测试它是否包含节点。 否则，使用pickObject获取对象–如果返回的结果undefined （我建议这样做），则返回错误消息，或者将pickObject调用包装在while result == undefined循环中。
