Creo API
[ARCHIVED] A multi-purpose api for Minecraft mod and datapack development.
About this Mod
This API has been archived and will not be updated. I may come back to it in the future, though.

Why should you use Creo API?
Creo API addresses three main issues not typically covered by other library mods.
- De-centralization of features, resulting in unnecessary similar or duplicated code from different mods.
- Tedious aspects of development that take time away from implementing fun, unique features.
- Expanding the powerful, yet lacking, worldgen & datapack system.
What's included in Creo API?
Here is a list of features implemented:
- Over 50 new Block, Item, Entity Type, Enchantment, & Biome tags
- Expanded version of BlockSettings & ItemSettings for easy modification
Vanilla is phasing these out in favor of the components system in 1.20.5+
- Utilities to edit vanilla blocks, items, & entity types
- Various Feature/Structure Placement, Density Functions, Placers, & Surface Rules to assist in worldgen
- FastNoise implementation
- Entity Attributes such as Block Place/Break Cooldown, Max Air, Climbing Speed, etc
- POI State & Block Entity Injection
- Customizable Entity-Block collision interactions
- Customizable Enchantment Targets
- Extensions to Blocks & Items for further customizability
- Even more small features
- And more to come!
Creo API targets both modders & datapack creators, aiming to provide both with useful features.
In order to optionally reduce file size, all modules are available to depend on separately.
We aim to be a higher-layer API on top of Fabric API (for modders) and Minecraft (for modders & datapack devs).

Creo API server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.
Is Creo API compatible with fabric?
Creo API officially supports fabric for Minecraft 1.21.1, 1.20.6, 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Creo API – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Creo API consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
