Overview

DayZ Epoch is an extensive modification built on top of DayZ Mod. It adds base building with plot poles, trader NPCs with a dynamic economy, banking system, enhanced vehicles, and custom loot tables. Epoch significantly extends DayZ's survival mechanics with persistent base construction and economy management.

Key Features

• Plot Pole System: Build bases with walls, floors, gates using plot poles for protection
• Trader Cities: Safe zones with AI trader NPCs selling weapons, vehicles, supplies
• Dynamic Economy: Prices fluctuate based on server supply/demand
• Banking: Deposit coins at traders, safe storage with interest
• Vehicle Spawns: Custom spawn system with database persistence
• Enhanced Loot: Custom loot tables with gems, rare items, crafting materials
• Crafting: Build storage boxes, sandbags, wire kits, metal parts

Epoch vs. Overpoch

• Pure Epoch: Standard Epoch with vanilla DayZ Mod base
• Overpoch: Combines Overwatch mod (military weapons/vehicles) with Epoch features
• Performance: Pure Epoch lighter, Overpoch more content but heavier

💾 Database Setup

Installing MySQL/MariaDB

Ubuntu/Debian

# Install MariaDB
sudo apt-get update
sudo apt-get install mariadb-server mariadb-client

# Secure installation
sudo mysql_secure_installation

# Start service
sudo systemctl start mariadb
sudo systemctl enable mariadb

Windows

# Download MySQL Community Server from mysql.com
# Or use XAMPP which includes MySQL

# Install MySQL Server
# Set root password during installation
# Start MySQL service from Services panel

Creating Epoch Database

# Login to MySQL
mysql -u root -p

# Create database
CREATE DATABASE epoch CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

# Create user with permissions
CREATE USER 'epoch'@'localhost' IDENTIFIED BY 'your_secure_password';
GRANT ALL PRIVILEGES ON epoch.* TO 'epoch'@'localhost';
FLUSH PRIVILEGES;

# If Hive is on different machine
CREATE USER 'epoch'@'%' IDENTIFIED BY 'your_secure_password';
GRANT ALL PRIVILEGES ON epoch.* TO 'epoch'@'%';
FLUSH PRIVILEGES;

Importing Epoch Schema

Epoch includes comprehensive SQL schema files:

# Import Epoch schema (adjust path)
mysql -u root -p epoch < path/to/epoch_server/SQL/epoch.sql

# Or import via MySQL client
mysql -u root -p
USE epoch;
SOURCE /path/to/epoch_server/SQL/epoch.sql;

# Import additional tables if using Overpoch
SOURCE /path/to/epoch_server/SQL/overpoch_additions.sql;

Epoch Database Tables (Key Tables)

Database Maintenance

Critical: Epoch databases grow rapidly. Regular cleanup is essential.

# Cleanup old objects (run weekly)
DELETE FROM object_data WHERE Datestamp < DATE_SUB(NOW(), INTERVAL 30 DAY) AND CharacterID = 0;

# Remove abandoned vehicles
DELETE FROM object_data WHERE ObjectUID IN (
    SELECT ObjectUID FROM object_data 
    WHERE Classname LIKE '%_DZ' AND Damage = 1
);

# Optimize tables
OPTIMIZE TABLE object_data, character_data, trader_data;

# Backup before cleanup!
mysqldump -u epoch -p epoch > epoch_backup_$(date +%Y%m%d).sql

🏗️ Base Building System

Plot Pole Mechanics

The plot pole is central to Epoch's base building:

• Range: 30m radius from pole (configurable)
• Protection: Prevents other players from building or destroying within range
• Maintenance: Must be maintained every 7 days or base decays
• Upgrades: Can upgrade with additional materials for extended range

Buildable Objects

Configuration (init.sqf)

// Plot pole settings (mission init.sqf)
DZE_PlotPole = [30,45];  // [Range in meters, Maintenance period in days]

// Building requirements
DZE_requireplot = 1;  // 1 = Require plot pole for building, 0 = Free build

// Building limit per plot
DZE_BuildingLimit = 150;

// Allow doorway building
DZE_doorManagement = true;

💰 Trader System

Trader Types

• General Trader: Food, medical supplies, basic tools
• Weapons Trader: Firearms, ammunition, explosives
• Vehicle Trader: Cars, trucks, motorcycles
• Helicopter Trader: Aircraft (expensive)
• Building Supplies: Construction materials, plot poles
• Black Market: High-end weapons, rare items

Currency System

Epoch uses briefcases of gold/silver coins:

• Gold Bars (10oz): 100,000 coins each
• Gold Bars (1oz): 10,000 coins each
• Gold Coins: 10 coins each
• Silver Bars (10oz): 1,000 coins each
• Silver Coins: 1 coin each

Dynamic Economy

Prices fluctuate based on server activity:

// Economy settings (mission init.sqf)
DZE_EconomyCore = true;  // Enable dynamic economy

// Price adjustment rates
DZE_PriceAdjustment = [0.8, 1.2];  // [Min, Max] multipliers

// Restock timers (in seconds)
DZE_RestockTimer = 1800;  // 30 minutes

// Banking interest rate
DZE_BankInterest = 0.001;  // 0.1% per day

Configuring Traders (trader_data table)

-- Add custom item to trader
INSERT INTO trader_data (item, qty, buy, sell, order, tid, afile) 
VALUES ('ItemGPS', 5, '[2,"ItemGoldBar",1]', '[1,"ItemGoldBar",1]', 0, 126, 'trade_items');

-- Adjust trader prices
UPDATE trader_data SET buy = '[1,"ItemGoldBar10oz",1]' WHERE item = 'M4A1_HWS_GL_camo';

-- Restock trader inventory
UPDATE trader_data SET qty = 10 WHERE tid = 126;

🚗 Vehicle System

Vehicle Spawn Configuration

Epoch uses vehicle_spawns table for dynamic spawning:

-- Add vehicle spawn point
INSERT INTO vehicle_spawns (vehicle, chance, position, direction, hitpoints, fuel, damage) 
VALUES ('UAZ_Unarmed_TK_EP1', 0.6, '[4532,9516,0]', 90, '[]', 0.5, 0);

-- Configure spawn chances
UPDATE vehicle_spawns SET chance = 0.8 WHERE vehicle LIKE 'Offroad%';

Vehicle Maintenance

• Damage System: Vehicles take damage and require repairs
• Fuel Consumption: Must refuel at gas stations or with jerry cans
• Locking: Vehicles can be locked with keys (database stored)
• Persistence: Saved/locked vehicles persist in database

Key System

// Key settings (mission init.sqf)
DZE_KeysAllow = true;  // Enable vehicle key system

// Key types
// Green key - Can access vehicle
// Red key - Owner, can give access

💸 Banking System

Banking Features

• Deposit Coins: Store currency safely at trader cities
• Withdrawal: Retrieve coins anytime at any trader
• Interest: Earn small interest on banked coins
• Death Protection: Banked coins don't drop on death

Configuration

// Banking settings (mission init.sqf)
DZE_EnableBanking = true;

// Banking interest rate (per day)
DZE_BankInterest = 0.001;  // 0.1%

// Max bank storage
DZE_MaxBankMoney = 10000000;  // 10 million coins

// Banking fees
DZE_BankFee = 0;  // No fee for deposits/withdrawals

Loot Tables (CfgLoot/)

Epoch includes custom loot tables in mission folder:

// Edit CfgLoot/CfgBuildingLoot.hpp
class BuildingLoot {
    class Supermarket {
        zombieChance = 0.3;
        maxRoaming = 2;
        zombieClass[] = {"zZombie_Base","z_hunter"};
        lootChance = 0.4;
        lootPos[] = {};
        itemType[] = {
            {"ItemSodaMdew",0.03},
            {"FoodCanBakedBeans",0.02},
            {"ItemBandage",0.01}
        };
    };
};

🔧 Troubleshooting

Base Not Saving

# Check object_data table
mysql -u epoch -p
USE epoch;
SELECT * FROM object_data WHERE CharacterID = YOUR_PLAYER_ID LIMIT 10;

# Common causes:
# 1. HiveExt not connecting to database
# 2. CharacterID mismatch
# 3. Database full / locked
# 4. Plot pole not placed correctly

# Check HiveExt.log
grep "object_data" HiveExt.log

Trader Not Working

• Verify trader_data table exists and is populated
• Check DZE_ConfigTrader = true in mission init.sqf
• Ensure trader AI is spawned in mission.sqm
• Check player is within safe zone radius

Vehicle Spawns Empty

# Check vehicle_spawns table
SELECT * FROM vehicle_spawns LIMIT 20;

# Adjust spawn chances if too low
UPDATE vehicle_spawns SET chance = 1.0 WHERE chance < 0.5;

# Force respawn (wipe existing vehicles)
DELETE FROM object_data WHERE Classname IN (SELECT vehicle FROM vehicle_spawns);

Database Growing Too Large

# Check database size
SELECT table_name, 
       ROUND(((data_length + index_length) / 1024 / 1024), 2) AS "Size (MB)" 
FROM information_schema.TABLES 
WHERE table_schema = "epoch";

# Run cleanup script (backup first!)
DELETE FROM object_data WHERE Damage = 1 OR CharacterID = 0;
DELETE FROM object_data WHERE LastUpdated < DATE_SUB(NOW(), INTERVAL 30 DAY);

OPTIMIZE TABLE object_data;

Players Losing Coins

• Ensure banking is enabled in mission config
• Check character_data table for coin field corruption
• Verify HiveExt is saving character data correctly
• Check for database rollbacks (restore from backup)
