Talent

A framework for identifying hype. Maybe someday. 😄

For now: yet another GoldSrc parser, built with fp-ts, and some utilities built on top of it!

Packages

Applications

Name Description On npm?
@cgdangelo/talent-jsonify-demo Runs the demo parser and logs to console.
@cgdangelo/talent-demo-renamer Renames a list of demo files to YYYY-MM-DD_HHMM_{map}.dem.
@cgdangelo/talent-example-demo-analyzer Example of a real-time demo analysis application using the demo parser event bus.

Libraries

Name Description On npm?
@cgdangelo/talent-parser-goldsrc Parser combinators for a GoldSrc demo file.
@cgdangelo/talent-parser-bitbuffer Parser combinators for bit-packed fields.
@cgdangelo/talent-parser-buffer Parser combinators for a Buffer.
@cgdangelo/talent-parser General use parser combinators.
@cgdangelo/talent-observable fp-ts bindings for rxjs observables.

What's working?

Demos can be parsed in their entirety. This includes all frame types, and all SVC_ engine messages contained with a NetworkMessages frame. User message parsing is limited to returning the message id, name, and raw data. Since the data in a message can vary between mods (e.g., DeathMsg) these parsers may have to reside in mod-specific packages.

What's coming? What's maybe coming?

The original goal of this project was to create a GoldSrc demo parser that could translate in-game events into readable data structures and emit them through observables for analysis. In particular, the ability to identify "hype" moments through some set of heuristics, such as:

  1. Multi-kills: Multiple frags at (roughly) the same timestamp, implying only one shot fired.
  2. Fast-paced streaks: multiple frags within a short period of time.
  3. High survivability: High number of frags between spawn and death.
  4. Events leading to a win condition, such as:
    • (Counter-Strike) Defusing the bomb with enemy players still alive could be a ninja defuse.
    • (Counter-Strike) Multiple kills in a disadvantaged situation (1v3, 1v4, 1v5) into a bomb defusal. This could be a CT retaking the bomb site and clutching the round.
    • (Day of Defeat) Multiple kills into a round win. This could be a streak that leads to a cap-out.
  5. Events that are otherwise important because of their circumstances:
    • (Day of Defeat) Breaking a double cap in progress when the enemy team controls all other flags, thereby preventing a cap-out.
    • A rapid change in crosshair angles followed by a kill. This could be a flick shot.
