How do I know what arguments a modifier takes?

[rattatatouille]

As the tin says, I want to know what arguments have to be passed to a modifier so that it takes effect.

Example, I have this modifier found in Expansion1_Modifiers.xml

MODIFIER_SINGLE_CITY_ADJUST_UNIT_PRODUCTION_MODIFIER

but I haven't found where it is used.

Since I don't know how the modifier is used, how can I see what arguments it takes?

You can look at the database used for civ 6 using a program like SQLite and then look at all the tables inside the database. There is one called modifier arguments.

There‘s a super useful tutorial on here for doing just that. I’m sure you can find it if you google sqlite tutorial civfanatics or something similar.

I recently wrote a tutorial on how to do this with SQLite Studio: https://forums.civfanatics.com/thre...-to-report-writing-with-sqlite-studio.629779/

BTW for this specific instance I would probably do this:

SELECT * FROM Modifiers
LEFT JOIN ModifierArguments on ModifierArguments.ModifierId = Modifiers.ModifierId
WHERE Modifiers.ModifierType LIKE "%MODIFIER_SINGLE_CITY_ADJUST_UNIT_PRODUCTION_MODIFIER%"

That's assuming MODIFIER_SINGLE_CITY_ADJUST_UNIT_PRODUCTION_MODIFIER is a ModifierType and not a ModifierId (they are different concepts).

The reason I'd run that join is so if ModifierArguments is blank for that Modifier, you know the Modifier is simply never used. If you don't do the join and try to query ModifierArguments directly, it will just show nothing at all if it is never used, which is a result I tend not to trust. In any case, if MODIFIER_SINGLE_CITY_ADJUST_UNIT_PRODUCTION_MODIFIER is a ModifierType and not a ModifierId you have to do that join anyway, since the ModifierType is only defined in the Modifiers table.
