There are third party plugins like my ANet plugin. ANet can be used with A6/A7 C-Script/Lite-C. (see signature!)
senssion_connect can only be used with gamestudio professional and send_var_id only with Lite-C.
But I would advice you to use a plugin for multiplayer and not the built in system because it lacks of confort and possibilities.
ANet - A stable and secure network plugin with multi-zone, unlimited players, voip, server-list features,... (for A7/A8)!
