About this project
What does MCT's Core add?
This API is an internal development tool created specifically for me and my development team. Its purpose is to provide a shared foundation for our existing and upcoming modding projects by offering common functionality and systems that our mods can depend on.
Important: This API is NOT intended for public use by other mod developers. It is exclusively designed to support my own mods and the projects developed by my team. You should only install or use this API if it is required by one of our mods. (So you can use this in your modpacks because some of my mods require it most likely)
Features and Purpose:
Internal Shared Functionality: Provides common systems and functionality used across our modding projects, avoiding the need to independently implement the same features in every mod.
Mod Dependency Support: Serves as a supporting dependency for selected existing mods and upcoming projects developed by me and my team.
Centralized Development: Allows us to maintain, update, and improve shared functionality in one central place, making development and maintenance of our mods easier.
Cross-Mod Integration: Provides a common foundation that allows our mods to utilize shared systems and functionality where needed.
Continuous Development: The API will be expanded and improved as our projects evolve and new requirements arise.
Development Status:
The API is currently still in a prototype stage. Despite this, it is already functional and serves its intended purpose for our current projects.
Since this API is actively being developed, its internal functionality, structure, and features may change over time. Updates will primarily focus on the needs of our own mods and development workflow.
Who Should Use This API?
My existing mods that require it.
My upcoming mods that list it as a dependency.
Members of my development team working on our projects.
Other mod developers should not use this API as a general-purpose development library. It is specifically maintained for our internal projects and is not designed or supported as a public API.
