MaxScript：檢測對象何時被刪除

Question

如果從場景中刪除對象，我將如何檢測（或觸發一個函數）？

Answer 1

使用notifications

fn nodeDeletedCallback = 
(
    deletedObj = callbacks.notificationParam() 
    print ("Deleting: " + (deletedObj as string)) 
) 

Callbacks.addscript #nodePreDelete "nodeDeletedCallback()" id:#id_AStringYouCanUseLaterToIdentifyThisCallback
