Create Optimized Trains

by GreenToastSoftware

Create Optimized Trains reduces the cost of Create train collisions and physics on Forge servers and clients running Create trains for 1.20.1 – 1.20.6.

ForgeClient-side onlyMIT LicenseOpen source1.20.1 – 1.20.6

What it does

The addon works with the Create mod trains and needs Create to run. Its settings file, create optimized trains-common.toml, lets server owners tune each optimization separately, with distances, intervals and toggles that control when each feature applies. The mod is client-side only, so servers run it without any player-side install.

Carriages are simulated at one of four fidelity levels: FULL uses real carriage physics when a player is nearby, MEDIUM simplifies the physics while keeping normal rendering, LOW keeps only minimal collisions and contraption updates, and GHOST renders an abstract entity that carries data only. The mod is published under the MIT License and is open source, with its source code and issue tracker public.

Key features

  1. Four simulation levels

    Each train runs at full, medium, low or ghost fidelity depending on how close a player is to it.

  2. Lighter collision checks

    Collision gathering collects bounding boxes directly from block shapes, cutting intermediate allocations that load the garbage collector.

  3. Adaptive throttling

    Train collision checks run every 4 ticks by default and slow to every 8 or 12 ticks when server performance degrades.

  4. Chunk preloading

    Chunks ahead of a moving train are loaded in advance, so trains keep moving without stutter.

  5. Backported Create fixes

    A set of Create fixes from a later release is carried over into this addon for the older game version.

Use cases

Busy train networks

Maps with 20 or more trains running at once are the case the throttling was built for, since collision checks there cost the most.

Who it’s for: Server owners running Create train networks on Forge who want to reduce tick load, and players on large multiplayer maps with many trains.

Questions

Does Create Optimized Trains require Create?

Yes. Create is the required dependency, and the addon works with Create mod trains on Forge for 1.20.1 – 1.20.6.

Does a player need the mod installed to join a server?

No. Players add it to their own game, and a server needs no copy.

Can the optimizations be tuned?

Yes. The create optimized trains-common.toml file sets distances, intervals and toggles for each feature individually.
