modc

ModC is an open-source modular content framework designed to simplify the creation, distribution, and management of game and application modifications. It provides a portable packaging format, a runtime loader, and an extensible API that lets mod authors add new items, behaviors, and interfaces without modifying the base code.

At its core, ModC isolates mod content from the engine using a manifest that declares dependencies, compatible game versions, and provided resources. Mods are packaged as .modc archives and can be installed through official mod managers or by placing them in a designated mods directory. During startup, the loader resolves dependencies, enforces sandboxing, and loads mods in a defined order.

Key features include a cross-engine plugin API, support for assets and scripts (notably Lua and JavaScript), data-driven configuration, versioning, and an online registry. The framework supports hot-reloading for development and aims to minimize conflicts between mods by strict resource isolation and a well-defined lifecycle.

Development and ecosystem: ModC began as an open-source project to reduce integration friction for modders. It has attracted contributions from independent developers and hobbyist studios. While it enjoys popularity in modding communities, its adoption varies by engine, and tooling maturity depends on the availability of engine adapters and documentation.

Licensing and availability: ModC is released under an open-source license and is maintained across public repositories and community wikis. Documentation covers installation, API references, packaging format, and guidance for developers and modders.
