Script is just... broken?

[Entih]

I found a semi-alternative, based on how they did it in the game in the Archives. Use the item 'diary_paper_01'. It has a diary pickup callback, apparently (info on the callback function parameters pop up if you hover the mouse over it).

Sadly, it also appears to be that the diary paper uses a bit of a different methodology for the text and name entries, being "Diary_<TEXTENTRYNAME>_Name<INDEXNUMBER>" and "Diary_..._Text...", with index meaning which numbered 'entry' it was, starting at 1. Have not used the diary versus note especially, myself, I cannot say just how any of this works.
