The camera dead-zone look-ahead layer filters small movement input before it can move the camera, then blends a look-ahead offset in the resolved movement direction. It preserves the base camera mode pose metadata while exporting the offset location through the camera manager contract.

Runtime Surface#

  • FV2CameraDeadZoneLookAheadConfig configures input dead zone, look-ahead distance, maximum offset distance, blend speeds, feature toggles, planar movement projection, and blend duration.
  • FV2CameraDeadZoneLookAheadState carries the base camera mode and current look-ahead offset.
  • FV2CameraDeadZoneLookAheadInput carries movement input and delta seconds.
  • FV2CameraDeadZoneLookAheadEvaluation returns raw and resolved input magnitude, movement direction, target and blended offsets, resolved location, mode specs, and validation issues.

Dead Zone and Look-Ahead Rules#

  1. Invalid config, state, or input timing is blocking.
  2. Input inside InputDeadZone reports DeadZoneHolding and resolves to zero.
  3. Input outside the dead zone is remapped to a zero-to-one analog magnitude.
  4. Movement can be projected to the horizontal plane before direction solving.
  5. Look-ahead offsets follow movement direction and scale by resolved magnitude.
  6. Offsets are clamped to MaxLookAheadDistance and report LookAheadClamped.
  7. Disabled look-ahead reports LookAheadDisabled and blends back to center.
  8. Releasing input uses RecenterBlendSpeed and reports RecenterComplete when the offset reaches zero.

Camera Manager Export#

EvaluateCameraDeadZoneLookAhead fills ModeSpec from the base camera mode with the resolved location and configured blend duration. BuildCameraDeadZoneLookAheadMode can export a custom id, priority, and active flag while preserving base camera rotation, FOV, blend function, input, and cinematic metadata.
