A few scripting questions

[Linus Ågren]

I think that it's better if I use this thread to make multiple questions rather than always making new threads all the time

First of all, how do you add notes, quests and diaries?
Secondly, a text on a door when you look at it (like engine room etc.. for a map-redicting door), and also a text that says like "Locked" if it is locked.

Third, almost same as the second but for normal doors. Make a text that says "locked" if it's locked.

Fourth, is it possible to name keys as you loot em?

I really need help with these ones ^^
I'll give anyone who help me get these to work credit when I release my map!

Thank you!
