Watch one player in the replay viewer

[SunkenInTime]

Reviewing a round usually starts with one player: what were they doing, and what could they see? VALORANT's own replay lets you jump into any player's eyes with 1–0, but no 2D viewer has an equivalent, including ours and ValoPlant's. Until now the viewer always showed all ten cones, and the only choice was which team's side to watch from.

What changed

• Pick a player by clicking their agent on the map, clicking their row in the roster, or pressing 1–5 (allies, top to bottom) or 6–0 (enemies). Picking the watched player again, or pressing Esc, stops watching. Clicking empty map does nothing, so a stray click never loses the watch.
• While watching:
  • Only that player's view cone is drawn.
  • Everyone else is drawn at 55%, without cones, and the watched player is drawn on top.
  • The camera glides to about 2× and keeps them centred left of the roster while playing or scrubbing.
  • Their roster row is raised with a violet ring, and each row's tooltip says "Watch Jett (3)" or "Stop watching Jett (3)".
• Moving the map:
  • Dragging stops following, but the watch stays; picking the player again resumes following.
  • Wheel zoom keeps them centred.
  • The watch carries through death, into the next round and across a side swap.
• Inside the frame: the other players' cones are left out of the frame itself, so they are never cut on the worker and a Capture while watching saves only the watched cone, exactly as drawn.
• Roster rows are keyed by player. Without keys, a side swap left each row in place to show another player. Stopping a watch after a swap then closed the app on Windows: a crash in Flutter's accessibility bridge, with an accessibility client reading the window. Astra hit this twice, and I reproduced it four times out of four with the sequence "watch, swap, stop watching". Keyed, it ran clean five times out of five.

How it was checked

• test/replay_watch_test.dart covers:
  • the frame keeping one cone and requesting no others;
  • the key slots, including after a swap;
  • Esc;
  • roster clicks, the selected look and the tooltips;
  • clicking the map;
  • centring, panning and wheel zoom;
  • the watched agent drawn last;
  • a swap never handing one player's row to another, which fails with the key removed;
  • Capture saving only the watched cone.
• In a release build on a 13.08 Abyss replay (Astra by hand, then me through an input driver that injects key and pointer events into the app):
  • Key 8, a roster click and a map click each watch the right player: centred, single cone, others dimmed, row selected.
  • Empty-map clicks keep the watch. Dragging stops following, and clicking the row resumes it. Wheel zoom stays centred.
  • Chamber stayed watched through his death and into the next round.
  • The swap sequence that used to close the app now plays on.
• Not checked: how smooth the camera feels at 1× and 4×. Screenshots show the positions are right, but neither of us could judge motion.
