Is it possible to make a building require a resource?

[sumaznguy]

Say I wanted to make certain settlements pernamently stay as villages/towns/etc. So only cities with the resource is able to upgrade to large city/fortress/etc.

And I imagine I would have to make some changes to avoid rebellion/massive squalor.

EDIT: Gah, i just realized this is the tutorial section and not the ask questions section. So would a mod kindly move this to the correct section?

You can use a hidden_resource in the EDB as requirement for a certain level of wall.
There is a maximum level of population for each wall level, beyond that it will not increase, no matter what.

It is possible, in fact, I am implementing it myself now. You can use two ways, first a resource (like gold) and second a hidden_resource (in the EDB). It depends on what is easier for you, or from which you use all the slots.

For reference, here is the EDB entry for mines which shows how you use resources(scroll right):

building hinterland_mines
{
    convert_to hinterland_castle_mines
    levels mines mines+1 
    {
        mines city requires factions { northern_european, middle_eastern, eastern_european, greek, southern_european, }  and resource silver or resource gold or resource tin or resource iron or resource sulfur or resource marble or resource coal
        {
            convert_to 0
            capability
            {
                mine_resource 4
            }
            material wooden
            construction  2 
            cost  2000 
            settlement_min large_town
            upgrades
            {
                mines+1
            }
        }
        mines+1 city requires factions { northern_european, middle_eastern, eastern_european, greek, southern_european, }  and resource silver or resource gold or resource tin or resource iron or resource sulfur or resource marble or resource coal
        {
            convert_to 1
            capability
            {
                mine_resource 7
            }
            material wooden
            construction  3 
            cost  3500 
            settlement_min city
            upgrades
            {
            }
        }
    }
    plugins 
    {
    }
}

I don't recall vanilla examples of hidden resources, but it's essentially the same thing except with hidden_ in front and you have to define it at the top of the file in this list:

hidden_resources sparta rome italy america atlantic explorers_guild swordsmiths_guild etc. etc. your_resource

There is a third way to do this.

monitor_event SettlementTurnEnd TrueCondition
    and SettlementBuildingExists blah blah
    set_event_counter building_exists 1
end_monitor

Any settlement that has the building will process the counter.


Then reset the counter for the start of every settlement:

monitor_event SettlementTurnStart TrueCondition
    set_event_counter building_exists 0
end_monitor

Require the event_counter in the EDB file. You can even use this to set different bonus levels. See this script for an idea how that works. That one is based on leader authority, but you can base it on anything as long as you get the processing order correct.
