How to add an unique entry to IDS

[qwerty12345]

I want to add an entry to shout.ids. How do I make sure that there will be no clashes with other possibly added by mods?

Similar to this:

// Adds CD_STATE_NOTVALID state
APPEND ~STATE.IDS~ ~0x80101FEF CD_STATE_NOTVALID~
UNLESS ~CD_STATE_NOTVALID~

that will just skip if there's such entry already. So my scripts will use this shared shout. I need a new, unique shout.

Erhm, it will skip if the UNLESS statement is true within the line... this allows you to build up a nearly endless of possibility ... say you wish a simple QHELP as the shout in your scripts, you can:

 

APPEND ~shoutids.ids~ ~131 QHELP~

UNLESS ~131~

 

Now then if the case is that the 131 is already occupied, you just...

 

APPEND ~shoutids.ids~ ~171 QHELP~

UNLESS ~QHELP~

 

Cover it... ETC.

that's the question, how do I choose the number that is not occupied.

You can use LOOKUP_IDS_SYMBOL_OF_INT to determine if any identifier is associated with a specific value. This will only guarantee you get a unique shout if you assume every mod that uses shouts actually adds an identifier to shoutids.ids.

 

SET val = 0
LOOKUP_IDS_SYMBOL_OF_INT identifier ~shoutids~ val
PATCH_IF (~%identifier%~ STRING_EQUAL ~%val%~) BEGIN
 // no identifier assigned to val
END

 

Combine it with a loop to keep searching until you find one that's unused.

 

 

Edit: Keep in mind that you'll need to recommend installing your mod after mods that are less careful about this sort of thing.
