Buildcraft

Buildcraft is a system designed for game development, particularly for Action RPGs, that treats authored content (skills, supports, items, rules) as input to a compiler pipeline. This pipeline transforms these inputs into runtime facts and derived caches, which are then consumed by the game's combat system. The core idea is to avoid complex, hardcoded special cases by using a compiler analogy where source facts are processed into runtime facts before the performance-critical path needs to interpret them. This approach aims to make authoring data simpler, manage combinations of game mechanics more effectively, and provide provenance for derived stats and behaviors, aiding in debugging and inspection.
