Crossplay Invites

Send Crossplay Invite takes Target, LobbyName, and Priority. Priority is Auto, Primary, Mirrors, or All; Auto uses the lobby policy. Its result maps each attempted FBetideProviderId to success. Both completion pins include FBetideError.

Show Crossplay Invite UI takes LobbyName and opens the first available selected provider whose lobby capabilities advertise an overlay. It is bound to that provider's copy of the lobby.

Joining a lobby publishes its crossplay connect string through every capable rich-presence backend. Leaving clears that value. Listen for invite delivery and acceptance through the Events subsystem.

See C++ usage.

Use a unified node first. Use a kit-specific invite node only for that platform's exact option set.
