Replay Data

clarity produces the following data you might be interested in from a replay. Choose from:

  • combat log: a detailed log of events that happened in the game
  • entities: in-game things like heroes, players, and creeps
  • modifiers: auras and effects on in-game entities
  • temporary entities: fire-and-forget things the game server tells the client about*
  • user messages: many different things, including spectator clicks, global chat messages, overhead events (like last-hit gold, and much more), particle systems, etc.*
  • game events: lower-level messages like Dota TV control (directed camera commands, for example), etc.*
  • voice data: commentary in pro matches*
  • sounds: sounds that occur in the game*
  • overview: end-of-game summary, including players, game winner, match id, duration, and often picks/bans

* unprocessed: data is provided as original protobuf message object
