# Forge Server Economy
|
|
|
|
## Overview
|
|
The economy addon contains server-side systems for world economic interactions
|
|
that are still implemented in SQF. It owns Arma-world behavior such as active
|
|
refueling sessions, medical spawn occupancy, respawn placement, and death
|
|
inventory handling.
|
|
|
|
Current stores cover fuel tracking, medical service behavior, and service
|
|
charges such as repairs and rearming.
|
|
|
|
## Dependencies
|
|
- `forge_server_main`
|
|
- `forge_server_common` for logging, formatting, and player lookup
|
|
- `forge_server_bank` (runtime) for player-funded medical billing
|
|
- `forge_server_org` (runtime) for extension-backed organization hot-cache charges
|
|
- `forge_client_actor` and `forge_client_notifications` for response RPCs
|
|
|
|
Note: Bank and Org are runtime-only dependencies (not compile-time requiredAddons). They must be loaded before economy stores initialize.
|
|
|
|
## Main Components
|
|
- `fnc_initFEconomyStore.sqf` tracks active refueling sessions, calculates fuel
|
|
totals, charges the player's organization through `OrgStore`, syncs the org
|
|
patch, and rolls fuel back to the starting level when organization funds
|
|
cannot cover the refuel.
|
|
- `fnc_initMEconomyStore.sqf` manages medical spawn occupancy, healing charges,
|
|
respawn placement, death inventory handling, and body-bag transfer. Medical
|
|
charges use player bank/cash first, then organization funds with repayable
|
|
member debt only when the player cannot cover the service.
|
|
- `fnc_initSEconomyStore.sqf` handles organization-funded service charges,
|
|
repairs, and rearming. Vehicle services only apply after the organization
|
|
charge succeeds. The
|
|
shared org-charge helper can also record member debt for medical fallback.
|
|
|
|
## Event Surface
|
|
The addon registers CBA server events for fuel start/tick/stop, direct refuel
|
|
service, repair service, player killed, player respawn, and healing. Medical
|
|
store initialization runs after post-init to discover configured medical spawn
|
|
objects.
|
|
|
|
Service results emit notifications and syncs through the event bus:
|
|
- `notification.requested` - service receipts and failure alerts
|
|
- `org.sync.requested` - organization balance updates after service charges
|
|
- `bank.account.sync.requested` - player bank/cash balance updates from medical billing
|
|
|
|
Repair service requests use:
|
|
|
|
```sqf
|
|
[QEGVAR(economy,RepairService), [_target, _unit, _cost]] call CBA_fnc_serverEvent;
|
|
```
|
|
|
|
`_cost` is optional. Passing `-1` uses the configured service repair cost.
|
|
|
|
Rearm service requests use:
|
|
|
|
```sqf
|
|
[QEGVAR(economy,RearmService), [_target, _unit, _cost]] call CBA_fnc_serverEvent;
|
|
```
|
|
|
|
`_cost` is optional. Passing `-1` uses the configured service rearm cost.
|
|
`setVehicleAmmo` has global effects, but only adds ammo to local turrets, so
|
|
the ammo reset is broadcast after billing succeeds.
|
|
|
|
Garage refuel service requests use:
|
|
|
|
```sqf
|
|
[QEGVAR(economy,RefuelService), [_target, _unit]] call CBA_fnc_serverEvent;
|
|
```
|
|
|
|
This fills the selected live vehicle after organization billing succeeds.
|
|
|
|
## Billing Rules
|
|
Economy does not own durable money state. It coordinates Arma-world effects
|
|
after the relevant hot-cache charge succeeds.
|
|
|
|
Fuel and repair services are organization-funded:
|
|
|
|
1. Resolve the player's organization from actor state.
|
|
2. Ensure the player is a member of that organization hot record.
|
|
3. Call `OrgStore chargeCheckout` with `source = "org_funds"`,
|
|
`commit = true`, and member service charging enabled.
|
|
4. Send the returned organization patch to online members.
|
|
5. If the charge fails, do not complete the service. Refueling rolls the target
|
|
back to its starting fuel level; repairs and rearming are not applied.
|
|
|
|
Direct refuel service requests, such as those from the garage UI, calculate
|
|
the missing fuel from `fuelCapacity`, charge the organization, and fill the
|
|
vehicle only after the charge succeeds.
|
|
|
|
Medical services are player-funded first:
|
|
|
|
1. Load the player's bank hot state.
|
|
2. Charge the player's bank balance when it can cover the medical bill.
|
|
3. Otherwise charge the player's cash when it can cover the bill.
|
|
4. If neither personal balance can cover the bill, charge organization funds
|
|
and record the same amount as a debt on the player's organization credit
|
|
line.
|
|
5. If personal billing is unavailable, or both personal and organization funds
|
|
fail, do not complete the heal.
|
|
|
|
The organization fallback reduces org funds immediately and adds the medical
|
|
cost to the player's credit-line balance due. Repayment uses the normal bank
|
|
credit-line repayment flow, which moves player bank funds back into the
|
|
organization treasury.
|
|
|
|
This keeps money mutation rules in the extension-backed organization service
|
|
and bank service while leaving world interactions in SQF.
|
|
|
|
## Notes
|
|
Fuel, medical, and service world behavior should stay server-authoritative
|
|
because it mutates inventory, vehicles, and respawn state. Money mutations
|
|
should continue to use extension-backed bank and organization hot state.
