Create Mod Configuration: Config Keys and Default Values

Create’s configuration is split across three TOML files managed by NeoForge’s config system. The files are generated automatically on first launch and can be edited while the game is running — most settings take effect on reload without a restart. All paths below are relative to your Minecraft instance root.

Config Files

File	Type	Location	Description
`create-client.toml`	Client	`config/`	Visual, UI, and sound settings. Per-player.
`create-common.toml`	Common	`config/`	World generation (ore rates, biome filters).
`create-server.toml`	Server	`saves/<world>/serverconfig/`	Kinetics, fluids, trains, schematics, recipes. Stored per-world.

Kinetics Config (`create-server.toml → kinetics`)

These settings are exposed by com.simibubi.create.infrastructure.config.CKinetics.

Accessing Config in Code

If your addon needs to read Create’s config values at runtime, use the static accessors on AllConfigs:

import com.simibubi.create.infrastructure.config.AllConfigs;

// Server-side kinetics config:
int maxBelt    = AllConfigs.server().kinetics.maxBeltLength.get();
int fanTime    = AllConfigs.server().kinetics.fanProcessingTime.get();
double medImpact = AllConfigs.server().kinetics.mediumStressImpact.get();

// Fluids config:
int tankCap    = AllConfigs.server().fluids.fluidTankCapacity.get();

// Trains config:
float topSpeed = AllConfigs.server().trains.trainTopSpeed.get();

// Client config (client-side only):
float density  = AllConfigs.client().fanParticleDensity.get();
boolean sounds = AllConfigs.client().enableAmbientSounds.get();

AllConfigs is part of Create’s internal infrastructure and is not considered public API. Its structure may change between Create versions. For settings your own mod exposes, define your own NeoForge config class rather than depending on Create’s internal config objects.
