  v4.5.0 — Enemy summoner-spell cooldowns Stable

  joeyr released this 2026-09-05 21:49:40 -05:00 | 22 commits to main since this release

  Added

  • Enemy summoner-spell cooldowns in the in-game overlay, driven by the chat
    lines your team's scoreboard pings post. Holding Tab and clicking an enemy's
    summoner spell writes 02:19 Name (Champ): Pantheon Flash to team chat; the
    overlay now reads that off the HUD and counts the spell down.

    Chat is the only signal available. Riot's Live Client Data API publishes no
    summoner-cast events and no champion positions, and the Tab scoreboard shows
    no enemy cooldowns, so nothing can detect a Flash automatically — a teammate
    still has to ping it. What is automated is the duration, which is the part
    every manual tracker gets wrong.

    Three properties of the chat line carry the design. It timestamps itself
    with the game clock, so OCR latency is irrelevant — a line read eight seconds
    late still yields an exact remaining cooldown, and there is deliberately no
    freshness gate (unlike the CS/clock fusion, which has one). That timestamp
    also dedupes: the same line is re-read every poll while it sits on screen,
    and champion|spell|time is stable across those reads. And both fields come
    from closed vocabularies — five enemy champions, nine spell names — so
    every parse is validated against a known set rather than trusting raw OCR,
    which is what makes fuzzy matching safe (Panlheon Fiash resolves; noise
    does not).

  • Haste-aware durations. Two sources are folded in, and they are not equally
    knowable. Ionian Boots of Lucidity (+10) is observed — items is
    published for every player on both teams, across the base, Arena and Classic
    Rift id blocks. Cosmic Insight (+18) is assumed: the live API exposes
    only the keystone and the two tree names for other players and never the minor
    runes, so the rune is inferred whenever Inspiration appears in either tree.
    The assumption is deliberately pessimistic — a timer that expires early is
    safe, one that expires late gets you killed — and the overlay marks those rows
    with a ° and a footnote so an assumed number is never mistaken for a
    measured one. Flash therefore reads 5:00, 4:33, 4:14 or 3:54 depending on what
    they have: a 66-second spread.

    Remaining time is derived per snapshot from current haste rather than stored
    as a deadline, so an enemy who buys Ionian Boots while Flash is down has the
    running countdown shorten itself the moment the boots appear in their
    inventory — which is what the game actually does.

  Changed

  • LivePlayerSchema now carries the payload's runes and summonerSpells
    blocks (both optional, matching the schema's deliberately lenient posture).
  • The chat OCR reader thresholds on the value channel (max(R,G,B)) rather
    than the CS reader's luminance. Pure red has a luminance of 76, below the
    existing threshold of 130, so a luma pass would have erased exactly the field
    that names the champion.
  • regions.json gains a chat box, calibrated on 3440x1440. It is optional in
    the schema, so an older calibration file still loads and simply leaves the
    tracker idle.
