Optional addons
Addons are separately installed NeoForge mods. The base Compukters mod works without them. The current first-party integrations target Minecraft 1.21.1; install matching addon and upstream mods on both client and server.
| Addon | Use it for | Guide |
|---|---|---|
| Compukters: Create | Kinetic devices, Stock Ticker logistics and steam boilers | Create |
| Compukters: Sable | Construction position, orientation, linear and angular velocity | Sable |
| Compukters: Propulsion | Creative Thruster and Creative Vector Thruster control | Propulsion |
Check compatibility
The JAR name contains both a Compukters target line and the addon’s own x.y version. For example,
compukters-create-1.21.1-neoforge-0.5-1.0.jar targets the Compukters 0.5 line and is addon version 1.0.
Loader metadata enforces the exact minimum base-mod version and upstream dependencies; the filename’s 0.5 does not
promise compatibility with every earlier patch. See each guide for the required upstream versions.
Enable an API in your program
Choose only the addons your project uses in compukter.toml:
format = 3
name = "construction-controller"
addons = ["sable", "propulsion"]
The attached server advertises available APIs to the IDE and compiler. A project lock records their exact versions and content hashes. An addon update may require resolving the lock again and rebuilding a program.
Create, Sable and Propulsion do not depend on one another’s Compukters addon. Their upstream mods have their own dependency requirements: installing Compukters: Propulsion still requires the upstream Create/Sable/Propulsion stack.
To expose your own integration, follow addon development. To test the complete physics stack from source, use the all-addon dev stand.
