Struct ControlFollowTracker 

pub struct ControlFollowTracker { /* private fields */ }

Watches the window after a touch to decide, by outcome, whether the touch was a control touch: did the toucher stay with the ball (close and speed-matched) or earn the follow-up touch? Resolutions are applied retroactively to the already-emitted touch event, mirroring how ball-movement credit is finalized.

At most one window is open at a time: any new touch closes the previous window, so the tracker never accumulates state.

Implementations

impl ControlFollowTracker

pub fn window_player(&self) -> Option<&PlayerId>

The player whose follow window is open, so the caller can supply that player’s frame sample to Self::advance.

pub fn open(&mut self, touch_index: usize, player_id: &PlayerId, time: f32)

Open a follow window for a just-emitted touch event. Only call this for touches whose action watches the possession axis (pass/neutral/clear/boom).

pub fn observe_touch( &mut self, player_id: &PlayerId, time: f32, ) -> Option<PossessionResolution>

Resolve any open window against a new touch. A follow-up touch by the same player within the window confirms possession directly (the touch enabled a follow-up) — control if the ball stayed close, advance if it was played into space first; a touch by anyone else, or a late follow-up, closes the window on the stay-close criterion.

pub fn advance( &mut self, frame: &FrameInfo, ball_position: Option<Vec3>, ball_velocity: Option<Vec3>, player_position: Option<Vec3>, player_velocity: Option<Vec3>, ) -> Option<PossessionResolution>

Accumulate one frame of follow data for the open window and resolve it once it ages out. Missing ball or player data counts as uncontrolled time (a demolished toucher is not in control of anything).

pub fn flush(&mut self) -> Option<PossessionResolution>

Close any open window immediately (live-play boundary or end of replay) on the stay-close criterion.
