This is a simple mod that sets the no fire tick gamerule to false everytime the game/server loads, which then stops fire from spreading in the world
🔥 How Fire Spread Works
Minecraft's fire system is governed by a repeating "fire tick" that controls whether fire spreads, burns blocks, or goes out.
The gamerule doFireTick determines whether fire behaves normally.
- Enabled (
true) → fire spreads, burns blocks, and extinguishes naturally - Disabled (
false) → fire becomes static and does not spread or burn anything
🔥 Why Fire Spread Matters on Servers
1. Fire spread can destroy player builds
On a multiplayer server, one careless torch, lava bucket, or lightning strike can:
- Burn down entire wooden bases
- Spread through forests
- Jump across roofs
- Trigger chain reactions
On a public or semi‑public server, this becomes a griefing vector, even if unintentional.
2. Fire spread causes lag
Every fire block performs multiple random tick checks:
- Should the fire go out?
- Should it spread?
- Which adjacent blocks are flammable?
- Should those blocks ignite?
In large forests or big builds, this can mean thousands of checks per second, especially during:
- Lightning storms
- Lava near trees
- Player‑made fires
- Nether hubs with lots of netherrack
Disabling fire spread reduces server load.

3. Fire can spread across unloaded chunks
This is a subtle one:
- Fire can start in a loaded chunk
- Spread to the border
- Load adjacent chunks
- Continue spreading
This can cause:
- Unexpected chunk loads
- TPS drops
- Large‑scale forest fires that nobody sees happening
Admins often disable fire spread to avoid these "invisible disasters."
4. Fire spread interacts badly with mods
On modded servers, fire can:
- Trigger block updates in modded blocks
- Cause tile entities to tick more
- Break machines
- Spread to modded wood types with high flammability
- Interact with worldgen structures in unpredictable ways
This is why many modpacks would want to ship with fire spread disabled by default.

5. Server rules and fairness
Many servers want:
- Decorative fireplaces
- Campfires
- Torches
- Nether portals
…but don't want fire to behave realistically.
Disabling spread allows fire to exist without risk.
Simply put this in the "mods" folder of you server or modpack. Server-side is fully supported.
