Live Split Timer

A LiveSplit-style speedrun timer for Factorio 2.0 / Space Age. It tracks the
total playtime and the time between configured milestones (triggered by
researched technologies, first visit to a planet, or scripted events such as a
rocket launch), comparing every split against your Personal Best.

Features

• On-screen HUD with a drag-and-drop window, collapsible view, and a progress
  bar showing how many milestones are already done.
• Expanded table view: one row per milestone with icon, name, split time, and
  the +/- delta versus your PB (green for ahead, red for behind).
• Dynamic row ordering: completed milestones float to the top in the order
  you actually reached them, while pending ones stay in the configured order.
  Readable under any planet routing — including abandoning a planet and
  coming back later.
• Collapsed view: only the current (next) milestone, for minimal distraction
  during an active run.
• Automatic scroll with focus on the current split when the milestone list is
  longer than fits in the window.
• Personal Best is built incrementally — the best time for each milestone is
  saved the moment it is beaten, even if the run is never finished.
• Per-milestone toggles, timer refresh interval, and PB reset available
  straight from the in-game mod settings.
• Full Polish and English localisation; no hard-coded user-facing strings.
• RCON interface for external tools: read current status, export PB, import PB
  from JSON, reset PB, submit the current run, or start a new run.

Milestones

The default milestone list covers 30 trigger technologies across Nauvis,
Space, and every Space Age planet (Fulgora, Gleba, Vulcanus, Aquilo). Adding a
new milestone only requires a single entry in config.lua — no locale edits
needed.

File locations

All persistent data is stored under Factorio's script-output directory.
On Windows that is %APPDATA%\Factorio\script-output\speedrun-timer\:

• pb.json — live best-segment Personal Best, updated every time you beat a
  milestone's previous best. This is what PB-delta in the HUD is compared
  against at the start of every run.
• current.json — mirror of the current run's splits, refreshed on every
  milestone. Intended for live integrations (overlays, stream widgets).
• runs.json — append-only history of completed runs (one JSON object per
  line), written when the final milestone is reached or when the run is
  submitted manually via RCON.

PB is also carried inside the save file, so it survives across mod updates.
The pb.json file is a cross-save fallback: copying it between installs (or
re-importing through the load_pb RCON call) transfers your Personal Best.

Changes

• 0.2.6 — Expanded HUD now orders split rows by when they were actually
  reached: completed milestones float to the top in chronological (tick)
  order, pending ones stay in the configured declaration order. Makes mixed
  planet routing readable and still supports abandoning a planet and coming
  back later.
• 0.2.4 — Fixed a hard crash on on_init when the Factorio build does not
  expose helpers.read_file. The check is now wrapped in pcall so the
  best-effort PB reload silently degrades instead of breaking new saves.
  Added release.bat for loose, unzipped releases.
• 0.2.3 — Current-run splits mirrored to current.json on every split for
  live-integration use.
• 0.2.2 — Three-level PB model: storage.milestones (current run),
  storage.pb (live best-segments), storage.pb_reference (frozen snapshot
  used for GUI delta). Delta no longer collapses to +0.0 when PB updates
  mid-run.
• 0.2.1 — Milestone list switched to 30 trigger technologies spanning
  Nauvis base, Space Age research, and every Space Age planet. Previous Space
  Age completion route is kept as a commented-out block in config.lua.
• 0.2.0 — Initial public release: HUD window, milestones, PB persistence,
  RCON interface, Polish and English localisation.
