Select player at mission start

[davidoss 552]

Hi.

 

I am trying to create a code where server pickup first player which is starting the mission and let him choose the position where the base will be spawned.

It should be a group leader and only one player selected. There are 3x20 playable units ,20 for each side + 2 headlescclients.

 

I have this:

 

init.sqf

private _players = [];
{_players pushBackUnique _x } forEach (((allPlayers + switchableUnits)) select {!didJIPOwner _x});
private _starter = (_players select {_x == (leader (group _x))}) select 0;
null = [] remoteExecCall ["MWF_fnc_getBasePos", _starter, false];
waitUntil {sleep 1; !isNil "F_BASE_POS" && {!(F_BASE_POS isEqualTo [])}};
{_x setPos F_BASE_POS} forEach (_players select {(side _x) isEqualTo (side _starter)});

 

MWF_fnc_getBasePos

				sleep 0.2;
				"Select position" hintC [ 
				"Single click on map to select your desired base position"
				]; 
				hintC_arr_EH = findDisplay 72 displayAddEventHandler ["unload", { 
					0 = _this spawn { 
						_this select 0 displayRemoveEventHandler ["unload", hintC_arr_EH]; 
						hintSilent "";
						hintC_arr_EH = nil;
					}; 
				}];
			};
		
			waitUntil{scriptDone _dxd && {isNil "hintC_arr_EH"}};
			openMap [true, false]; 
			onMapSingleClick "F_BASE_POS = +_pos; true";
			waitUntil {sleep 1;!visibleMap || {!(F_BASE_POS isEqualTo [])}};
			onMapSingleClick "";
			if (visibleMap) then {
				openMap [false, false];	
			}; 
		};
		
		waitUntil {sleep 0.2; (speed player) > 0};
			
		while {(F_BASE_POS isEqualTo [])} do {
				
			private _poshandle = [] spawn _fnc_getmapposition;
			waitUntil {sleep .2; scriptDone _poshandle};
				
		};
		publicVariableServer "F_BASE_POS";
	};

 

 

Unfortunately this  works only if hosted or SP. On dedicated its go to somewhere and no one player gets function execute without any error

After some tests i realise that this code runs too early on dedicated where are no players in game.

I edit this to:

waitUntil {sleep 1; (count ([] call BIS_fnc_listPlayers)) > 0};
private _allplayers = [] call BIS_fnc_listPlayers;
waitUntil {sleep 1;({getPlayerUID _x != ""} count _allplayers) > 0};
private _players = _allplayers select {(side _x) isEqualTo GVAR_FSIDE};
private _starter = (_players select {_x == (leader (group _x))}) select 0;
null = [] remoteExecCall ["MWF_fnc_getBasePos", _starter, false];
waitUntil {sleep 1; !isNil "F_BASE_POS" && {!(F_BASE_POS isEqualTo [])}};
{_x setPos F_BASE_POS} forEach (_players select {(side _x) isEqualTo (side _starter)});
[[format ["selected %1 from side %2",STR _starter, STR (side _starter)], "PLAIN", 1]] remoteExec ["titleText"];

It works but this is very nasty, kind of workaround.

Please help, how to correct write such thing.
