Is there a way to save an empire's opinion of another into a variable?

[Liggi]

There seems to be various ways to check an empire's opinion against a flat number, or compare their relative opinion to another empire.

But what I'm trying to do is something like:

For <x empire>, save <y empire>'s opinion into a variable, say @opinion_of_x_empire

And then check to see if there's any other empire that <y empire> has a higher opinion of.

So if <y empire> has an opinion value of <x empire> of 20, but they like any other empire in the galaxy 50, it would return true.

Is there a way to achieve this?

You need the following effect:

export_trigger_value_to_variable - Exports the value of a trigger to a specified variable (so for num_pops, it'll export the number of pops).
export_trigger_value_to_variable = {
    trigger = pop_produces_resource
    parameters = { resource = energy } (optional: specify extra parameters for triggers with { }
    variable = <string> (this example will print the amount of energy the pop produces to a variable)
    rounded = yes (default: no)
}
Supported Scopes: megastructure planet country ship pop fleet galactic_object leader army ambient_object species pop_faction war federation starbase deposit sector archaeological_site first_contact spy_network espionage_operation espionage_asset agreement situation

And following trigger:

check_variable - Checks a variable for the country/leader/planet/system/fleet
check_variable = { which = <variable> value >=< <float>/<variable>/<scope.variable>/trigger:<trigger> }
Supported Scopes: megastructure planet country ship pop fleet galactic_object leader army ambient_object species pop_faction war federation starbase deposit sector archaeological_site first_contact spy_network espionage_operation espionage_asset agreement situation

or even

check_variable_arithmetic - Checks a variable for the scope if a certain amount of arithmetic is done to it (note: the variable's value is not changed by this trigger)
check_variable_arithmetic = {
    which = <variable>
    add/subtract/multiply/divide/modulo = <float>/<variable>/<scope.variable>/trigger:<trigger> (note: this line can be repeated as many times as desired)
    value <=> <float>/<variable>/<scope.variable>/trigger:<trigger> (the value to compare against)
}
Supported Scopes: megastructure planet country ship pop fleet galactic_object leader army ambient_object species pop_faction war federation starbase deposit sector archaeological_site first_contact spy_network espionage_operation espionage_asset agreement situation

if you want to do more complex things.

Export following trigger:

their_opinion - Checks target country's opinion value of the current country
their_opinion = { who = <target> value > 25/variable }
Supported Scopes: country

or other opinion triggers, depending on your choice. See https://github.com/OldEnt/stellaris-triggers-modifiers-effects-list
