MovementState Component Self-sufficient kinematic analyzer. Every field is derived from the entity's own position-over-time and ground proximity — no producer has to push state into MovementState, no other component has to exist for it to work. Reads are O(1). On each read we look at the current position and the previous sample; if a non-zero amount of wall-clock time has passed since the last sample, we update the cached velocity and store the new sample. Multiple reads inside one frame return the same cached velocity (no jitter from redundant divisions). `grounded` / `falling` / `sliding` derive from a single short downward Physics raycast; the result is cached for the same frame. Anyone can attach this to any entity that moves through any means — CharacterController, physics rigidbody, animated transform, networked replication, scripted teleport. MovementState reports the same shape regardless of how the position changed. Usage: local ms = self.entity.component.get("MovementState") if ms.grounded then ... end local speed = ms.horizontalSpeed -- Writing is forbidden; the proxy raises a read-only error.
