Hey guys.
Please allow me to request a bit of help.
I've been trying to alter some of the mods I'm using lately, like changing some of the dialog, to correct typos, for instance.
Using Construction Set, it's pretty easy, even for an amateur like me. Quest menu, righjt ?

Something I have yet to figure how to do though, is how to edit notifications ?
You know, some mods will display notification messages at the top of the screen, sometimes.
For instance, in the Real Sleep mod, as your character gets sleepy, you'll get popup messages such as "I need to sleep", etc, depending on the status of the character.

I'd like to alter some of the messages from this precise mod (not the whole game), to make them more to my liking. I guess it's probably pretty easy to do, but I just can't figure out how.

Could anybody point me to the right direction ?

Those would be in the 'script' using a 'Message' for the top left display, or 'MessageBox' for a pop-up window.

Thank you for taking the time to help me out, Willie. That's much appreciated.
I'm doing fine with Construction Set's quest options, but the script part is a bit hard for me...

May I ask how to proceed exactly, if it's ok ?

To edit text dialog, I had to go to the quest menu, then select either Topics or Conversation... the rest was easy.
But how should I proceed to edit script generated popup text ?

Taking http://www.tesnexus.com/downloads/file.php?id=24649 as an example.
Would it be possible to alter the text of the popups saying how tired the character is ?
That's merely what I'd like to do...

IIRC, Real Sleep has several scripts attached to quests and they are prefixed RSE.

Click Character on the menu bar and select quests.
Find a quest Rsixxxxxxx and click on it.
Click on the ... box next to where the script is listed.

That opens the script window with the particular script attached to the quest.

Scroll through the script and look for the word message or messagebox (there might be an ex at the end).
Everything between the " " is what appears in game.
Be careful to read first. Some messageboxes are menu boxes, not messages.
If you see variables on the same line after the quote marks, don't mess with that one.

Edit to your heart's content.

It worked.
I was able to achieve what I wanted by opening the esp directly from the script window.

Many thanks for your help, guys
