LivingCity

A city that lives without players.

Every small roleplay server knows the feeling: a beautiful map, a finished gamemode — and three players online at 3 AM. The world feels dead, so the three players leave too.

LivingCity fixes the feeling at its root. It is a virtual-citizen economy engine for SA-MP / open.mp: up to 200 simulated citizens (Los Santos, San Fierro, Las Venturas) who hold jobs, earn hourly wages, spend money on food, fuel, shopping and rent, pay city tax into a treasury, receive stipends when they are broke, and push a dynamic market index that moves your prices up and down — every minute, whether anyone is online or not.

It is distilled from the city economy of AMERTA Roleplay, a live Indonesian roleplay server whose city runs on exactly this design, and released free for every server that ever felt empty.

Proof it runs

Compile-clean with pawncc 3.10 (zero errors, zero warnings). Booted on a real samp03svr:

[12:06:35] [LivingCity] 200 citizens moved in. Treasury $25000. Market index 1.000.

Install

1. Copy livingcity.inc into your pawno/include (or qawno/include).
2. In your gamemode:

#include <livingcity>

public OnGameModeInit()
{
    LC_Init();
    // ...
}

public OnGameModeExit()
{
    LC_Exit();
    // ...
}

1. Done. Your city now has an economy. A ready-to-run demo lives in examples/livingcity_demo.pwn — log in and type /citystats.

Hook your real economy in

// Price anything by the living market index:
new price = LC_CityPrice(500);            // 500 at index 1.00, 350 at 0.70, 750 at 1.50

// Route a player purchase through the city: tax lands in the treasury.
new tax = LC_RegisterPlayerPurchase(price, LC_CITY_LS);   // LS / SF / LV tax rates differ

LC_GetTreasury();                          // city treasury balance
LC_GetMarketIndex();                       // Float, 0.70 .. 1.50
LC_GetCitizenMoney();                      // total money in citizen wallets
LC_PrintStats();                           // one-line economy report to the server log

The model (AMERTA's rules)

• 200 citizens by default, split roughly LS 120 / SF 45 / LV 35.
• Finite wallets. Citizens earn wages per job and spend from what they actually have — nobody conjures money.
• City tax on every purchase: LS 10% / SF 12% / LV 8%, into one treasury.
• Stipends: citizens under the floor get help from the treasury, so the poor never flatline and the treasury actually circulates.
• Market index: drifts up to ±2% every 6 ticks, clamped to [0.70, 1.50], and scales every price you pass through LC_CityPrice.

Every knob (MAX_LC_CITIZENS, LC_TICK_MS, tax rates, spend chance, stipend floor/amount) is a #define you can override before the include.

Indonesian: mesin ekonomi warga virtual untuk server roleplay SA-MP / open.mp. Warga simulasi bekerja, menerima gaji, belanja, membayar pajak ke kas kota, dan menggerakkan indeks pasar — kota tetap hidup walaupun tidak ada pemain online. Diambil dari desain ekonomi kota AMERTA Roleplay.
