用於在3ds Max中選取對象名稱的MaxScript

Question

您好同胞堆棧溢出成員！首先，感謝您花時間閱讀這個問題。

我正在學習Maxscript，所以我可以做一些快速和複雜的面部鑽機。 我的腳本已完成99％。唯一的問題是，現在腳本已經硬編碼了要被操縱的目標對象的名字（下面代碼中的「MYOBJECT」）。我不想在MaxScript中忽略對象的名稱，而是想創建一個函數，該函數將打開一個對話窗口，要求我單擊目標面對象，然後在用戶單擊目標對象後，我的代碼將完成它已經能夠完成的工作，但使用選定的對象名稱而不是硬編碼名稱。

我的代碼是波紋管。非常感謝您的幫助！

如果你有一個用戶界面，使用​​和測試，如果它在運行之前持有的節點。否則，使用pickObject獲取對象 - 如果返回的結果是undefined（我建議），或者將pickObject調用包裝在while result == undefined循環中，則退出並顯示錯誤消息。
