Code for check:
Client init:
waitUntil {!isNull player};
swt_player = player;
publicVariableServer "swt_player";
Dedicated server init:
"swt_player" addPublicVariableEventHandler {
_player = (_this select 1); diag_log ("TEST IS PLAYER " + str _player + ": " + str (isPlayer _player); //"TEST IS PLAYER R Alpha 1-1:1 REMOTE: false"
};
Also allPlayers return [] on briefing on dedicated server
