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.
