OSP Kit Campaign Trade with caravans

[neutroceparus]

I've done some trading with caravans.
On native 1.171/1.174
Initially it was in mod that I do for myself.
Post factum I recognized, that there is caravan trade in Floris Modpack, but works different than mine.
It's not tested in the long run, but seems to be ok.
I've done some scripting tricks, also many things can be done other way.
Changed code is marked orange.
Credit goes to: Lav and other people who made Tweaked MS 1.166 - especially for great operations documentation,
kalarhan - I used tips that he posted to someone in QA Thread
and other community members who done documentation, tutorials, forum answers etc.
Feel free to use it and modify

There must be enough custom caravan masters for every active caravan. Can be calculated from script create_kingdom_party_if_below_limit, but i prefer to add some more.

Basically what it does is using custom kind of NPCs as leaders of Caravans. They are taken from pool and returned when defeated in battle. Refreshing inventories takes place when the caravan is spawned, or visit city. This trade system doesnt have any connection with loot from caravan or economy system.

Wow, that's a very neat idea! Especially for those of us who think Native has a lot to give still.

 

[Corbul]

Just what I was looking for! Thanks you kindleh!

Hello Friend. I know my comment has nothing to do with the topic but I really wanted to ask you a question.
Some OSP codes have smiles, when copied to .py files they are in codes, example ": cool:". And python doesn't recognize it. How to fix this?
If you can help me I would be very happy.
I'm sorry to the topic owner for putting my question here.
I don't know if this is against any rules, I'm new here, but if it is, let me know and I delete my comment.

 

[Antonis]

Hello, I hope neutroceparus doesn't mind but I will answer you. The smiles are because of the forum. Generally, it's this that has a problem

8)

that makes it problematic.
So, when you see ": cool ", it is actually

Oh I see, thank you friend <3

 

[Antonis]

No problem.

 

[Mauromagno Patriota]

I installed the code and it works fine but I have some doubts:
1.- For example, in my mod I have 28 cities and many trade routes .... What does the number of caravan master in troop influence? Should I add more or less according to the number of routes?
2- even though the face code is for mercenaries (which I also use in the mod's mercenaries), the faces of the caravan bosses appear very different.(very deformed xd)
3- How could I add more products for sale? So far I have only seen no more than 7.
4- why are so many horse items in the troop?
Thank you

Hello,

What does this line do?

["caravan_masters_end","caravan_masters_end","caravan_masters_end",tf_hero, 0,0, fac_commoners,[],def_attrib|level(2),wp(20),knows_inventory_management_10,0],

 

[Eärendil Ardamírë]

Hello,

What does this line do?

It's a dummy troop which marks the end of the caravan masters.

 

[LoneFennec]

hope I understood better, this OSP allow the player to have many caravans and send them to trade?
thanks

 

[Eärendil Ardamírë]

No, it allows the player to approach the caravan and be able to trade with them.

 

[LoneFennec]

No, it allows the player to approach the caravan and be able to trade with them.

Thank you for clearing things for me, I appreciate it.
