HeTu

Use when writing the Unity/C# client of a HeTu (河图) game — connecting / logging in with HeTuSessionClient, RPC via CallSystem, or live data via WatchRow / WatchRange (R3 subscriptions); also when subscribed rows show only their initial value and never update live, or a reconnect overlay / session-state handling is needed.

Use when building or extending a game server / realtime backend on the HeTu (河图) engine — writing Components, Systems or Endpoints in app.py, wiring a Unity/C# client's RPC and subscriptions, configuring backends, or deploying with the hetu CLI. An index into HeTu's model, public API and source; follow the links for specifics.
