Implements SOCD (Simultaneous Opposing Cardinal Directions) functionality that provides competitive gaming advantages through "last key wins" behavior for opposing directional keys. Features: - Universal syntax: &st <key> <opposing_key> works with any key pair - Dynamic state management supports up to 16 key pairs simultaneously - Memory efficient: only stores state for active pairs - Gaming optimized: perfect for FPS strafing, platformer movement, MOBA control - Zero performance impact when behavior is not used Usage example: &st A D // A key with D as opposing key &st W S // W key with S as opposing key The behavior solves the problem where pressing opposing keys (like A+D) causes character to stop moving by automatically releasing the previous key when its opposing key is pressed, enabling instant direction changes without dead zones |
