How to make a unique/exclusive trait? [SOLVED]

[Teodosio]

Hello fellow players,
I have an idea about implementing a "praetorian prefect" concept in my game. I would like to do that using a trait rather than an ancillary, because I want to use that trait to influence character's development (i.e. other traits will be affected by it).
The problem of course, is that I should have ONLY ONE praetorian praefect; while one exists no one else should get the trait, even if the triggers are right.

So my question is: how can I do that? I know it is possible to have unique ancillaries (many in BI are unique), I would like to do the same for this trait, but I don't know how to do that.

Thank you for attention!

sorry it isn't possible to have a unique trait the commands that are used for unique ancillaries don't work in traits file.

You can give a unique trait to one character in descr_strat - it will remain 'unique' so long as you don't make trigger, therefore no-one else gets it.

Only way I found to get a unique trait otherwise (which I needed as only traits have epithets) was to give character a unique ancillary first that had a 'naval command effect' . that doesn't actually have any effect for infantry generals, so you can use the naval command ability as trigger for him getting the trait you want. He'll get it when the trigger fires after he gets ancillary, so would have to be on next turn at earliest.

It's rather messy but couldn't think of anything else. Unless you can put a trigger that fires once only in a campaign script.. not sure about that.

makanyane you are a GENIUS. This will surely do the work.
I imagined a dirty solution was needed here, but I don't care much. The important thing is to achieve the result. I was thinking about a script too, but avoiding it feels "safer", because otherwise if the player forgets to activate the script strange things could happen. It's better to do it using standard game mechanics.

Thank you very much for your help, very precise and quick!

I will add [SOLVED] to thread's name as soon as I have tested out everything.
