    BWAPI

    BWAPI

    An API for interacting with Starcraft: Brood War (1.16.1)

    Brood War Application Programming Interface or BWAPI is a free and open source C++ framework that is used to create Artificial Intelligence (AI) agents that play the popular Real Time Strategy (RTS) game Starcraft: Brood War. With BWAPI, players of varying levels can create AI agents to play Brood War, but with certain limits. BWAPI will only reveal visible parts of the game state to AI modules to enable programmers to write competitive non-cheating AIs. BWAPI also denies user input so users cannot take control of game units while the AI is in play. These default settings can be changed for flexibility however, unless enforced by a Tournament Module (game referee for AI tournaments).
