I took the list serialize list code from someone, and it was posted on a wiki somewhere... (If this was you, please add your name so I can credit you).


I'm not one for writing documentation, so I apologize in advance for the confusion of the following.



Here is a map of the objects:

Object To Data
|
|---Object_Main (Script)
|---Listen (Object)
|---|
|---|---Listen_Main(Script)
|---HoloBox (Object)
|---|
|---|---Holo_Main (Script)
|---|Data_Default (Note)


Now that everything is set up, drag the last script into every PRIM. No objects can be linked. Then, click Save Program. The objects WILL DELETE THEM SELF, so be careful. Copy and paste the text into a note, exactly as it appers in the chat log. No need to remove any dates, or the object name. Simply paste it.
