Using a positive would not solve the logical contradition of

kelt_govt_4 requires factions { gauls, } and hidden_resource indo_european and hidden_resource not_indo_european

Besides, it wastes hidden resources and creates extra work in having to code hidden resources for every region.

[Dol Guldur]

Um, you'd use the not_indo_european HR instead of the not indo_european, not together in the same argument. But in any case, if it is tested this way and still fails then he may have the factions with a gap.

FATW covers most things, as do other mods; just see how they get around it.

[Centurion Varricus]

is it possible the building faction works like the faction capability, ie building capability?

EDIT: tested and no it doesnt

[Dol Guldur]

I think I pretty much tested all possibilities - there might be some posts in this thread about it if you search. Good luck though :)

[PatricianS]

Hey,

Great Guide! Really usefull.

I had a question though... Is there a way to require a specific building level in a tree? (ie not only a level and all levels that come after it)

I have already tried to do this:

requires building_present_min_level treeX level_2 and not building_present_min_level treeX level_3

The code above does work, but when shutting the game down this seems to cause an error saying

[..] Gap in building tree prior to building [...]

If there is no solution for this, is there then maybe a way to block this error message? It seems kid of useless to me since the code simply works...


Thanks in advance!!

~ PS

[Thor the Bassist]

a way to block this error message?

Remove -show_err from your shortcut. If you need to test things and you think this error is blocking other errors then simply put a ; before the "and not" part and then test. Bit of a pain but thats all I can think of unless there's another problem other than what you've quoted.

[PatricianS]

Unfortunately this error seems to appear whenever you make a requirement for something and then in the same line make it a "requires not"... It happens with hidden resources as well as with the same building tree :(

Guess that's the only options left then... Thanks for the answer :D

Make a hidden resource that is not present in any region and add an 'or' condition to the end of the requirements line. Like this:

requires building_present_min_level treeX level_2 and not building_present_min_level treeX level_3 or hidden_resource nowhere

I use this for filling in all sorts of "gaps" in the building DB. I tested this quickly, and it all seemed to work as intended with no error message.

hmm...

Thanks for thinking, but this won't work :(

The game gives an error already on the first part of this line... (before your "or hidden_resource nowhre")

I'm afraid that the only option is what Thor the B. said... with the ; in front of the trouble area's... :(

[DimeBagHo]

The game gives an error already on the first part of this line... (before your "or hidden_resource nowhere")

Are you sure you didn't just make a mistake with the earlier conditions? I tried a couple of versions:

blacksmith requires building_present_min_level market trader and not building_present_min_level port_buildings port or hidden_resource nowhere

blacksmith requires building_present_min_level market trader and not building_present_min_level market forum or hidden_resource nowhere

Both loaded fine. With the first one the blacksmith was available to build in settlements with a trader, but not in settlements with a port. Afterwards the game exited fine with no error messages from either version. Obviously you need to add the resource 'nowhere' at the top of EDB.

I've found an interesting phenomenon concerning the Carthaginian culture UI bug.

What I found was that after working around the bug (deleting a line referencing Carthaginian in DUB) and loading my mod, I could re-add the line for Carthaginian in DUB with no ill effects.

This may not seem like a big deal, but it means I don't have to create new UI cards for the Carthaginian culture for every new (non-eastern) building.

In fact, I just realized that the Extended Greek Mod benefits from this, perhaps unknowingly, because it doesn't use any special Carthaginian UI cards, but clearly has new buildings from vanilla. And my modifications of the Extended Greek Mod also include new buildings, some exclusively for Carthage, and I created no new cards either.

[Squid]

Technically, you never have to create new UI cards, you just need to copy the UI card from the appropriate culture folder and rename it.

[CaesarVincens]

Well, I know, but I meant that that is unnecessary as well. The game correctly finds the cards from the other cultures with no problems.

[Ramashan]

I have coded in a building tree with more than one upgrade and have had it work fine. But I'm trying to make a tree that up grades different buildings for different factions. The code looks like this;

building taverns
{
    levels tavern tavern_faction1 tavern_faction2 tavern_faction3 tavern_faction4 
    {
        tavern requires factions { pontus, dacia, egypt, armenia, numidia, } 
        {
            capability
            {
            }
            construction  1 
            cost  200
            settlement_min village
            upgrades
            {
                tavern_faction1
                tavern_faction2
                tavern_faction3
                tavern_faction4
            }
        }
        tavern_faction1 requires factions { pontus, dacia, } 
        {
            capability
            {
            }
            construction  2 
            cost  800 
            settlement_min town
            upgrades
            {
            }
        }
        tavern_faction2 requires factions { egypt, } 
        {
            capability
            {
            }
            construction  2 
            cost  800 
            settlement_min town
            upgrades
            {
            }
        }
        tavern_faction3 requires factions { armenia, } 
        {
            capability
            {
            }
            construction  2 
            cost  800 
            settlement_min town
            upgrades
            {
            }
        }
        tavern_faction4 requires factions { numidia, } 
        {
            capability
            {
            }
            construction  2 
            cost  800 
            settlement_min town
            upgrades
            {
            }
        }
    }
    plugins 
    {
    }
}

I can build the tavern but I don't get the option to build any of the factional upgrades. What am I doing wrong or overlooking? Any help would be appreciated.

[Thor the Bassist]

You could try making the effects faction specific rather than the buildings faction specific although that code looks right so it should work.

[Aradan]

Try changing the conditionals like that:

1st-faction: requires factions { pontus, dacia, } or factions { egypt, armenia, numidia, } and hidden_resource non-existant
2nd-faction: requires factions {egypt, } or factions { armenia, numidia, } and hidden_resource non-existant
3rd-faction requires factions {armenia, } or factions { numidia, } and hidden_resource non-existant
4th-faction: requires factions {numidia, }

[Ramashan]

I did as you suggested Aradan and now I can construct the next level. However, it seems to just completely ignore the the requirements and the construction tree shows only the info for what ever building level is next in the building tree regardless if the faction is a requirement or not.

[lim_lucky]

I am currently modding my own version of RTW and I am using the ALEXANDER engine, not RTW or BI. I am not 100% sure that this has not been posted, but it is not in the EDB guide so I decided to post what I found:

under the upgrades:

building government
{
levels gov1 gov2 gov3 gov4 gov5 gov6 gov7 gov8
{
gov1 requires factions { ... } ;(1)
{
capability
{
...
}
construction 1
cost 200
settlement_min village
upgrades
{
gov2 requires factions { romans_julii, } and not hidden_resource italy
gov6 requires factions { romans_julii, } and hidden_resource italy
gov7 requires factions { romans_julii, } and hidden_resource italy
gov2 requires factions { carthage, } ;and hidden_resource
gov2 requires factions { egypt, } ;and hidden_resource
gov3 requires factions { egypt, } ;and hidden_resource
gov4 requires factions { egypt, } ;and hidden_resource
gov2 requires factions { armenia, } ;and hidden_resource
gov3 requires factions { armenia, } ;and hidden_resource
}
}
;...
gov2 requires factions { ... } ;(2)NOTICE no requirements
;...
}

When I tried this out in the game, the gov2, 6 and 7 buildings for romans_julii was only present in places with the hidden resources as specified even though the gov2, 6, 7 buildings DID not have any requirements tied to it - refer to (2).

This opened up a lot of possibilities for me because I was no longer restricted to doing the usual building requirements in the opening statement - refer to (1) which did not allow complex conditions.

I have not tested whether there will be a CTD, but it seems to run fine for a few turns of testing. However, there is draw back as the game always report an error only upon quitting, which is harmless from my point of view.

I have yet to try this out, but I plan to use such a function to create the following upgrade statements based on hidden resources which will define specific regions:

e.g.
upgrades
{
upgrade1 requires factions { romans_julii, } and hidden_resource 1 and hidden_resource 2
upgrade2 requires factions { romans_julii, } and hidden_resource 2 and hidden_resource 3
upgrade3 requires factions { romans_julii, } and hidden_resource 4 and hidden_resource 5
upgrade4 requires factions { romans_julii, } and hidden_resource 6 and hidden_resource 7
upgrade5 requires factions { romans_julii, } and hidden_resource 1 and hidden_resource 9
;... etc.
}

[lim_lucky]

I have coded in a building tree with more than one upgrade and have had it work fine. But I'm trying to make a tree that up grades different buildings for different factions. The code looks like this;

This is a continuation from my earlier post, I believe my upgrade options will the solution.

	gov2 requires factions { ... }
	{
		capability
		{
;imperium
		law_bonus bonus 1 requires factions { romans_julii, }

I have not had time to digest this yet, but an exit error report is not a good sign. Even if there is no underlying potential game-breaking issue, the error may mask more serious reports associated with other elements of the modification.

I would avoid any error reports whatsoever.

In response to your concerns, I have extracted the error after exiting the game. I hope you can enlighten me on the seriousness of such an error because I usually try to ignore such errors and add a simple condition to avoid such errors from occurring.

Script Error in exrm/data/export_descr_buildings.txt, at line 10059, column 4. Building DB error - faction romans_julii has a gap in building prior to gov6

The line 10059 corresponds to the last line in export_descr_buildings.txt
I will skip many of the unnecessary coding and jump to the crucial parts because the coding is correct as the game is able to load. The reason for the "gap" is because the structure of my government building for romans_julii is as follows:

;building levels
levels gov1 gov2 gov3 gov4 gov5 gov6 gov7 gov8

;gov1
upgrades
{
gov2 requires factions { romans_julii, } and not hidden_resource italy
gov6 requires factions { romans_julii, } and hidden_resource italy
gov7 requires factions { romans_julii, } and hidden_resource italy
}

;gov2
upgrades
{
gov3 requires factions { romans_julii, } and not hidden_resource italy
gov4 requires factions { romans_julii, } and not hidden_resource italy
gov5 requires factions { romans_julii, } and not hidden_resource italy
}

;gov3
upgrades
{
gov8 requires factions { romans_julii, }
}

;gov4
upgrades
{
gov8 requires factions { romans_julii, }
}

;gov5
upgrades
{
gov8 requires factions { romans_julii, }
}

;gov6
upgrades
{
gov8 requires factions { romans_julii, }
}

;gov7
upgrades
{
gov8 requires factions { romans_julii, }
}

I haven't tested this code out but I suppose it should remove the exit error, i.e. by attaching a hidden resource requirement which will not be present at all.

gov1 requires factions { romans_julii, } and not hidden_resource not_here

I have not fully tested what I discovered because I have yet to link up the rest of the buildings for all the factions. If it works, I do not need to rely simply on scripts to settle the complex building requirements like some mods like EB has done. Once I have settled all the government details of all the factions, I would do a test and show my findings.

[Dol Guldur]

We look forward to your findings. Seems interesting!

Do remember to test it both ways (positively and negatively) as sometimes a piece of redundant or useless code that is not reported as incorrect may nevertheless pass as a positive and mislead.

I meant, with the exit report, that the game seems to only report one error (or one sort of error) and it therefore may mask another error at work - so it's always good to make sure you resolve an exit error when it appears.

Best of luck.

[CaesarVincens]

Excellent find, lim_lucky.

I'll be doing some testing with this as well.

[lim_lucky]

Best of luck.

Before I proceed with the findings, I have 1 question: Dol Guldur, what do u mean by testing it both ways?

I'm finally completed with the building description and some upgrade options.
Before I continue with the findings, I have to stress that I am only using the ALEXANDER engine, not RTW or BI so I cannot guarantee it will work for the older engines.

I will first summarize all the details which are indicative of my findings:

1) Upgrade statements based on hidden resources which defines specific regions may be possible for different factions within the same building tree, however note that this is only based on a one time testing which is definitely not exhaustive. This sort of solves the complex logic required to allow different factions to have different upgrade options in different regions.
e.g.
upgrades
{
upgrade1 requires factions { romans_julii, } and hidden_resource 1 and hidden_resource 2
upgrade2 requires factions { cathage, } and hidden_resource 2 and hidden_resource 3
upgrade3 requires factions { egypt, } and hidden_resource 4 and hidden_resource 5
upgrade4 requires factions { scythia, } and hidden_resource 6 and hidden_resource 7
;... etc.
}
2) The upgrade options seem to reject building_present_min_level requirements as it will CTD on the turn the building is completed.

3) I have not checked whether the following requirements will work because it do not intend to use it in my upgrade options for my personal mod.
resource
building_present
marian_reforms
building_present

4) After I have allocated the hidden resources in the other regions, I will continue to post any other findings, especially with regards to other faction upgrade options once their hidden resource requirements are filled. I really hope it will work well with the rest of the factions.

Disclaimer: I only intend to post whatever I find asap, and I have no intention to test upgrade requirements as stated in 3. Any other modder should be able to test it easily, but I feel that a 'positive test' does not seem to expand the building options that much and I am quite tight with other commitments as well, so I'm giving it a miss.

Details:
I have only tested with the factions romans_julii, because I have yet to place other hidden_resources for the other factions. So please ignore code for all other factions for simplicity.

According to the above codes, specifically for gov2, gov6 and gov7, the building options will be present as long as the hidden_resources stated in the upgrade options match the logic.
For instance, in the region Insubramrog, hidden resource SW, B, n1, y2, n4, n8 is present, but hidden resource italy is absent, so 2 upgrade options gov2 and gov6 is present. Locations with hidden resource italy also has 2 upgrade options gov6 and gov7.

Upgrade options for gov1 building in EXPORT_DESCR_BUILDINGS.TXT:
		gov2 requires factions { romans_julii, } and not hidden_resource italy
;Insubramrog
		gov6 requires factions { romans_julii, } and hidden_resource SW and hidden_resource B and hidden_resource n1 and hidden_resource y2 and hidden_resource n4 and hidden_resource n8 
		gov7 requires factions { romans_julii, } and hidden_resource italy

Respective region in DESCR_REGIONS.TXT:
Insubramrog
       Mediolanum
       gauls
       Insubre
       221 232 41
       river, SW, B, y1, n2, n4, n8
       5
       2
	christianity 10 pagan 90 zoroastrian 0

Regrettably, the codes within the upgrade options as shown below do not work:

;gov1 building ...
		upgrades
		{
		gov2 requires factions { romans_julii, } and not building_present_min_level hinterland_loc1 a_italia ;The intention was to use buildings as a requirement and not hidden resource italy
		gov6 requires factions { romans_julii, } and building_present_min_level hinterland_loc1 a_italia
		}

The building option for gov1 will definitely be present, but the game will immediately CTD in the turn when gov1 is completed. That means, I never even get to see whether gov2 and gov6 are buildable options in the correct regions because the game just CTD once it reaches the start of the turn.

Before I proceed with the findings, I have 1 question: Dol Guldur, what do u mean by testing it both ways?

I meant that sometimes it will appear that an added condition is being parsed as true when in fact it is simply being ignored, so it should be tested the other way (usually by putting something in that you know is false or just plain nonsense to see if it reports an error or CTDs etc).

You've probably done this by now - I, like you, and too stretched to even look at this right now but I am sure others will at some point.

I do have a vague recollection that I had tried conditionals on the upgrade lines some years ago (probably under an early version of RTW) but cannot remember the result. Obviously, if I had got it to work I would have mentioned it. Maybe I did it wrong, looked at the results incorrectly or maybe that version was not as flexible - Thanks for exploring and testing!

I hope someone can confirm your findings soon!

[PatricianS]

Great find!

I'm surely going to test this... It adds so much more options when designing rather complex building trees :)

(I'll let you all know if I find something interesting (working/not working/limited working))

Thanks!!

(sorry for not just editing my previous post, but I can't find how to do that :P)

I just tested the upgrade requirements with the walls building tree.

I tested:

requires factions { rome_republic, }
Worked as expected
- Only Rome can upgrade walls

requires hidden_resource not_used
Worked as expected
- Walls can't be upgraded (no region has this HR)

requires hidden_resource rome
Worked as expected
- Walls can only be upgraded in the city Roma

requires not hidden_resource italy
Worked as expected
- Walls can only be upgraded outside of Italy

requires building_present_min_level core_building governors_palace
Worked as expected
- Only cities with a core building "Governors Palace" and higher can upgrade the walls

:)

Did you get an error message on exit?

Nope.

I also haven't tried yet to get one...

However when experimenting a bit further, I did get a "gap in building tree prior to blabla"-error. And it surely came from the upgrade requirement. Meaning that the requirement does not get ignored. :)

Good, good.

OK, I have added:

Upgrades, it would seem, can also take conditionals. For more discussion and examples of this please see lim lucky's posts on page 6 of the EDB discussion thread here: https://forums.totalwar.org/vb/showth...t=50039&page=6
