FireSpread
Transform fire into a real threat! This server-side mod adds realistic fire spread mechanics to DayZ, making every campfire a potential disaster. Watch as flames jump from your fireplace to nearby trees, buildings, and vehicles in a dynamic and dangerous way.
- Dynamic Fire Spreading – Fires spread naturally from fireplaces to nearby flammable objects within a 3-meter radius
- Distance-Based Probability – Closer objects are more likely to catch fire, creating realistic propagation patterns
- Multiple Flammable Types – Trees, bushes, buildings, wooden structures, and vehicles can all ignite
- Progressive Building Damage – Structures take gradual fire damage and eventually collapse
- Vehicle Explosions – Cars catch fire and explode after 5-15 seconds, damaging nearby players
- Vegetation Burning – Trees and bushes burn for 30 seconds before extinguishing
- Server-Side Only – No client download required, perfect for server administrators
- Fully Configurable – Adjust spread radius, probability, damage, and more
Simply light a fireplace anywhere in the world. The mod automatically detects burning fires and checks every 2 seconds for nearby flammable objects. Each object within the spread radius has a chance to ignite based on:
- Distance from the fire source (closer = higher chance)
- Base spread probability (default 30%)
- Object type (buildings, trees, vehicles, etc.)
Once ignited, objects become new fire sources that can spread to other nearby objects, creating chain reactions!
Buildings & Structures
- Houses, sheds, barns, and garages are all flammable
- Take 10% health damage per spread interval
- Eventually collapse when health depletes
Vehicles
- Fuel tanks take 50% damage when ignited
- Engine destroyed immediately
- Explode after random delay (5-15 seconds)
- Explosion deals damage in 10-meter radius
Vegetation
- Trees, bushes, and dead vegetation can catch fire
- Burns for 30 seconds before auto-extinguishing
- Creates opportunities for forest fire scenarios
For Server Administrators:
- Subscribe to this mod on Steam Workshop
- Add -mod=@FireSpread to your server startup parameters
- Restart your server
- Fire spread is now active!
No client-side installation required! Players will automatically sync with the server.
All settings can be customized in FireSpreadConfig.c:
This mod significantly changes fire mechanics in DayZ:
- Base Defense: Indoor fires become risky – your base could burn down!
- Forest Camping: Campfires in forests can ignite trees and spread
- Urban Warfare: Fires in cities can damage buildings and vehicles
- Strategic Element: Use fire as a weapon or create diversions
- Survival Challenge: Players must be more careful where they place fires
- Optimized update system (2-second intervals)
- Automatic cleanup of extinguished fires
- Maximum fire lifetime prevents infinite spread
- Minimal server impact with efficient object tracking
- DayZ Version: 1.20+
- Server-Side: Yes (runs entirely on server)
- Client-Side: Not required
- Mod Conflicts: Should work with most mods
- Required Addons: DZ_Data, DZ_Scripts (vanilla)
Planned features for future updates:
- Weather effects (rain reduces spread probability)
- Fire extinguishers and water buckets
- Smoke inhalation damage
- Player-created fire sources (molotovs, flares)
- Firefighter equipment and roles
- Custom flammable object lists via config files
- Visual particle effects for burning objects
- This is a server-side mod – only server admins need to install it
- Visual particle effects are basic/minimal in current version
- Fire spread is permanent until objects are destroyed or fires extinguish naturally
- Maximum fire lifetime is 10 minutes to prevent server issues
- Objects are tracked to avoid repeated fire checks (performance optimization)
- Particle effects are currently minimal (proper fire visuals coming soon)
- Dense forests can cause rapid chain reactions (adjust SPREAD_CHANCE if needed)
- Weather integration not yet implemented
Free to use and modify for your DayZ server. If you use this mod, credit is appreciated but not required!
🔥 Light a fire. Watch it spread. Survive the consequences. 🔥
Remember: With great fire comes great responsibility!
