SQF owns Arma-facing storefront discovery and request validation. The Rust extension owns authoritative checkout calculation through store:checkout.

Dependencies

forge_server_main
forge_server_common
forge_server_extension at runtime for checkout calls
forge_server_actor, forge_server_bank, and forge_server_org at runtime for checkout context and payment state
forge_client_store for response RPCs

Main Components

fnc_initStore.sqf marks editor-placed store objects with isStore = true.
fnc_initCatalogService.sqf scans live Arma config categories, builds catalog responses, resolves checkout entries, and calculates authoritative catalog prices. It also applies the optional mission CfgStore filter and overrides before payloads or checkout validation use catalog entries.
fnc_initStorefrontStore.sqf builds hydrate payloads, validates checkout requests, calls store:checkout, syncs client patches, and coordinates related bank/org persistence. Purchased units are fulfilled by spawning the granted unit classes at discovered unit_spawn markers after the backend charge succeeds.

Mission Catalog Filter

Missions can include CfgStore.hpp from description.ext to control the generated catalog without changing the addon.

class CfgStore {
    mode = "allowlist"; // dynamic, allowlist, or denylist
    modMode = "dynamic"; // dynamic, allowlist, or denylist
    mods[] = {}; // ModSources class names used when modMode is not dynamic

    class ModSources {
        class rhs {
            patches[] = {"rhs_main", "rhsusf_main"};
            addons[] = {"rhs_", "rhsusf_", "rhsgref_", "rhsafrf_"};
            prefixes[] = {"rhs_", "rhsusf_", "rhsgref_", "rhsafrf_"};
        };

        class ace3 {
            patches[] = {"ace_main"};
            addons[] = {"ace_"};
            prefixes[] = {"ace_"};
        };
    };

    class Categories {
        primary[] = {"arifle_MX_F", "arifle_MXC_F"};
        cars[] = {"B_MRAP_01_F"};
        units[] = {"B_Soldier_F"};
    };

    class Overrides {
        class arifle_MX_F {
            price = 2500;
            displayName = "MX Rifle";
            description = "Approved PMC service rifle.";
        };
    };
};

dynamic keeps the full generated catalog. allowlist only shows classnames listed for the requested category. denylist removes listed classnames from the generated category. Overrides are applied server-side, so checkout validation uses the same prices and descriptions the UI displays.

modMode applies before category filtering. allowlist only keeps generated entries that match one of the configured mods[]; denylist removes matching entries. Each ModSources child can define patches[] to detect whether the mod is loaded, addons[] for config source addon/source mod names or classname prefixes, and prefixes[] for classname prefixes. If a mod source defines no patches, it is treated as available and only the source/prefix checks are used.

units[] follows the same dynamic, allowlist, and denylist behavior as item and vehicle categories. Unit purchases are immediate spawn grants, not durable virtual garage unlocks.

The filter is currently global for the mission. Revisit per-store profile support if individual vendors need different inventories.

Unit Spawn Markers

Purchased units spawn at mission markers named unit_spawn, unit_spawn_1, unit_spawn_2, and so on. The store resolves the closest initialized store object to the requesting player, scans allMapMarkers at fulfillment time, and uses the closest matching marker within 25 meters of that store.

If no matching marker exists within 25 meters, the store falls back to spawning units around the store object. If no store object can be resolved, it falls back to the requesting player so checkout still completes.

Editor Entities

fnc_initStore matches non-null mission namespace objects whose variable names contain store, mirroring the garage entity initialization pattern.

Checkout Flow

Store checkout can charge cash, bank balance, organization funds, or approved credit lines depending on the hydrated session context. Checkout results can grant locker assets, organization assets, fleet vehicles, and immediate unit spawns through the related domain stores and Arma server runtime.

Checkout results emit notifications and syncs through the event bus:

notification.requested - receipt and transaction alerts
bank.account.sync.requested - player balance updates
org.sync.requested - organization balance and asset updates
locker.sync.requested - item grant notifications
garage.vgarage.sync.requested - vehicle grant notifications
