[General] Modify item sold/made stock

[Jaccouille]

Hello,

My context :
I got a player-controlled building selling items like the melee race shop.
I want to manipulate the building item stock, add or reduce the stock amount.

I've seen some native such as AddItemToStock, but I couldn't make it work.

Doc - AddItemToStock

Question: Is this possible with player building or does this only work with neutral merchant?

 

[Chaosium]

IIRC those shop inventory manipulation actions only work if items have been previously added by a trigger themselves

I am doing something similar in my altered melee map The Bandit's Crucible.

The Bandit's Crucible v1.6

The Bandit's Crucible v1.5 Created by Fleck Map Info: Play as the Bandits with their unconventional faction, relying on hiring a steady stream of hardened mercenaries to fight for them or their allies instead of training new recruits from the spoils of war! Features: New units New heroes New...

Your custom shop also needs the Sell Items ability in order for Neutral Building - Add/Remove Item-Type (From Marketplace) to work.

Under Techtree - Items Made of your shop should contains only items that you want the shop to always have like Scroll of Town Portal, Tome of Retraining, etc.

My custom item shop
Upon finishing building a Black Market, starts with an additional random set of items. The item pool refresh randomly from a range between 220-300 seconds with 60% chance for a new set of items.

Free free to check my map in world editor or Hive's preview triggers.

There is a difference between "shops" vs "marketplaces." There is a thread somewhere on Hive about this but I can't find it.

The stock settings will affect shops,
but the triggers do not affect shops.
You can't add items to shops with triggers - only marketplaces.

If you want to manipulate the stock of an item sold in a shop then you need to edit that item's stock settings in Object Editor.

What Chaosium said applies to marketplaces.
What Flek said about abilities applies to both and the 2nd part appplies to shops only.

There might be a better way but this is my understanding.

Thank you for the answers, I managed to accomplish my idea.
I wanted to have some kind of shared stock for different items. See linked gif.

[Duckfarter]

Adding an item to a marketplace with -1 in stock will display 0 and hide the stock replenish interval if that is something youre interested in.

I didn't know that, thanks for the tip.
