asobi_game_join (asobi v0.84.0)

Dispatch to a game module's join callback, preferring the context-carrying join/3 when the module exports it.

Shared by asobi_match_server and asobi_world_server so the two cannot drift on which arity wins.

Summary

Functions

Call Mod:join/3 if exported, otherwise Mod:join/2.

Functions

invoke(Mod, PlayerId, Ctx, GameState)

-spec invoke(module(), binary(), map(), term()) -> {ok, term()} | {error, term()}.

Call Mod:join/3 if exported, otherwise Mod:join/2.

The export check runs per join rather than being cached at init: a module can gain or lose join/3 across a hot code upgrade, and a cached decision would keep calling the arity that no longer exists.
