Marker problem on dedicated server

I've been trying to help some guys with a small program, it all works a part from a maker issue.

In the editor I have a marker and you can rotate it to set the direction of moved vehicles.

In single player this works but when run on a dedicated server the direction isn't reset.

part of script.

// null=[trigname,"marker1",5] execvm "clear.sqf"
_clear = _this select 0;// trigger name
_carpark = _this select 1;// marker name for car placement
_delay = _this select 2;// delay before removal 

while {true} do {

_vehicles = [];

sleep _delay;// time before empty vehicle is removed

_vehicles = entities "landvehicle"; 

{
  if ( _x iskindOf "landvehicle" and count crew _x == 0) then {
   sleep 0.1;
      if ( [_clear, getpos _x] call BIS_fnc_inTrigger) then {
        _position = getmarkerpos _carpark findEmptyPosition [ 1 , 100 ,typeof _x];
          _x setpos  _position;
           _x setdir markerdir _carpark;// only works in single player
         };};

} foreach _vehicles
};

I don't do mp scripting so can't test myself, but does anyone have a clue about this?

Thanks Sel.

youll have to use add public event handler and have it for both local player and the server - how i use JIP markers

Thanks but after reading it makes no sense to me as I don't do any MP, if if they really want it they can sort it out themselves.

creating the marker

if (isServer) then 
			{

			_marker = createMarker [_markname, position _preplacedmkr];
			"terrorHelpers" setMarkerShape "ELLIPSE";
			"terrorHelpers" setMarkerType "DOT";
			"terrorHelpers" setMarkerSize [150, 150];
			"terrorHelpers" setMarkerColor "ColorRed";			
			} 		
				else 
				{			

				objmkr = [_markname, _preplacedmkr]; publicVariable "objmkr";			
				};

init

if (isServer) then 
{
"objmkr" addPublicVariableEventHandler 
{
	_marker = createMarker [((_this select 1) select 0), position ((_this select 1) select 1)];
	"terrorHelpers" setMarkerShape "ELLIPSE";
	"terrorHelpers" setMarkerType "DOT";
	"terrorHelpers" setMarkerSize [150, 150];
	"terrorHelpers" setMarkerColor "ColorRed";
};
};

I must be having a really thick day but I still don't get what creating markers has to do with getting the direction of a pre placed marker in MP.

ah ok, the marker needs to be moved either locally for the player, or for both server and local player (from what i can tell).

i had problems with JIP and MP getting a marker to show up on both. Then i had issues getting it to follow a moving unit. SO by making sure the same marker was created on all connected clients/and server- it seemed to work. worth a try :) if not when i get a chance i can look for you.

probably not explained that very well lol.

Cheers, I'll give them a few things to try and see what happens.
