Overview

IgnisCore extensions are platform-agnostic JARs loaded at runtime. This section covers building, testing, and deploying them.

Quick start

1. Copy an existing extension under extensions/blocks/ or extensions/items/
2. Add Maven dependency on api (provided scope)
3. Implement a strategy class extending AbstractIgnisBlockStrategy or AbstractIgnisItemStrategy
4. Ship block-extension.yml / item-extension.yml, config.yml, and textures
5. Build with mvn package and deploy to the plugin data folder

<dependency>
  <groupId>dev.rono</groupId>
  <artifactId>api</artifactId>
  <version>1.0.0</version>
  <scope>provided</scope>
</dependency>

Documentation layers

Layer	What it covers
Extension Cookbook	Practical recipes — explosions, throwables, GUI blocks
API Reference	Core API and extension-shared helpers
Architecture	Module stack, boot flow, dependency rules
Javadoc	Full class and method reference
Sample extensions	Working JARs in the repo

The website is intentionally thin — detailed API signatures live in Javadoc. The cookbook shows you how to do common tasks with links to the relevant classes.

Two libraries

Library	Maven artifact	When
Core API	dev.rono:api	Always — strategies, ports, models
Extension shared	dev.rono.extensions:shared	Optional — typed config helpers (ExplosionConfig, ThrowableItemConfig)

Both use provided scope — the bootstrap plugin supplies them at runtime.
