Hello,

I want to trigger when the player insert a marker on his map in a specific area, like in the prologue mission, where you have to find AAF position (youtube link :

).
If you have any link or answer which can help me, please post it!

Thanks.

In the script, the marker _mk is the one the player just placed.

I guess you have a trigger with an area somewhere. Name it (mytrigger for example).

Then in the script you can check on a condition:

if (_mk inArea mytTrigger) then  {....};

 

NB: That works also with another marker ellipse or rectangle type. No need to be a trigger.

yeah, I've used something similar like this in a script before. For detecting how close a user placed marker is near a town, pretty simple

How sould I define mytTrigger? I have an error : Undefined variable in expression: mytTrigger.

I search on the forums but don't figured out how to define my trigger/area in the script.

 

Thank you for your previous messages.

If you placed a trigger on map, just name it (say myTrigger or what ever you want), then check if the marker I named _mk in the script is inArea of this variable name like this:

 

_MGI_taskOnMarker = addMissionEventHandler ["map",{
  if (_this select 0) then {
    [] spawn {
      _mks = allMapMarkers;
      private ["_tgt","_tgtText","_mk"];
      while {visibleMap && hasInterface} do {
        waitUntil {!(_mks isEqualTo allMapMarkers)};
        if (count allMapMarkers > 0) then {
          _mk = allMapMarkers select (count allMapMarkers - 1);
          if (_mk inArea myTrigger) then { < do what you want > };
        };
        _mks = allMapMarkers;
      };
    };
  };
}];

Why not just use a double click eventhandler on the map control, wait for the insert marker dialog to popup then add a unload event to it.

The double click will give you the position that was clicked and the unload will give you the exitcode which will tell you whether a marker was placed.

 


TAG_fnc_createSelectionMarker = {
	_position = player getPos [ random 500, random 360 ];
	
	if !( getMarkerPos "border" isEqualTo [ 0, 0, 0 ] ) then {
		deleteMarker "border";
	};
	
	_mrk = createMarker [ "border", _position ];
	_mrk setMarkerShape "ELLIPSE";
	_radius = 50 + floor random 100;
	_mrk setMarkerSize [ _radius, _radius ];
	_mrk setMarkerBrush "Border";
	_mrk setMarkerColor "ColorBlue";	
};

TAG_fnc_waitForPlayerInput = {
	waitUntil{ !isNull findDisplay 12 };
	findDisplay 12 displayCtrl 51 ctrlAddEventHandler [ "MouseButtonDblClick", {
		params[ "_mapCtrl", "_button", "_mouseX", "_mouseY" ];
		
		if ( _button isEqualTo 0 ) then {
			player setVariable[ "insertPos", _mapCtrl ctrlMapScreenToWorld[ _mouseX, _mouseY ] ];
			
			_nul = [] spawn {
				
				waitUntil{ !isNull findDisplay 54 };
				
				_nul = findDisplay 54 displayAddEventHandler [ "Unload", {
					_exitCode = param[ 1 ];
					
					if ( _exitCode isEqualTo 1 ) then {
						
						if ( ( player getVariable "insertPos" ) inArea "border" ) then {
							hint "You placed a marker inside the Area";
						}else{
							hint "You placed a marker outside the Area";
						};
					};
				}];
			};	
		};
	}];
};

openMap true;
hint "Place a marker either inside or outside the area shown";
_nul = [] call TAG_fnc_createSelectionMarker;
_nul = [] spawn TAG_fnc_waitForPlayerInput;

Just run the above in the debug console whilst previewing a mission.

 

Commented code..

Spoiler


//Function to place a marker for the player to click in/out
TAG_fnc_createSelectionMarker = {
	_position = player getPos [ random 500, random 360 ];
	
	if !( getMarkerPos "border" isEqualTo [ 0, 0, 0 ] ) then {
		deleteMarker "border";
	};
	
	_mrk = createMarker [ "border", _position ];
	_mrk setMarkerShape "ELLIPSE";
	_radius = 50 + floor random 100;
	_mrk setMarkerSize [ _radius, _radius ];
	_mrk setMarkerBrush "Border";
	_mrk setMarkerColor "ColorBlue";	
};


TAG_fnc_waitForPlayerInput = {
	//Wait for the map to open
	waitUntil{ !isNull findDisplay 12 };
	
	//add Dbl click event to map
	findDisplay 12 displayCtrl 51 ctrlAddEventHandler [ "MouseButtonDblClick", {
		params[ "_mapCtrl", "_button", "_mouseX", "_mouseY" ];
		
		//if the mouse button was the left one
		if ( _button isEqualTo 0 ) then {
			//Save clicked world position in player variable
			player setVariable[ "insertPos", _mapCtrl ctrlMapScreenToWorld[ _mouseX, _mouseY ] ];
			
			//Create a new thread so we can wait again
			_nul = [] spawn {
				
				//Wait for insert marker popup
				waitUntil{ !isNull findDisplay 54 };
				
				//Add UnLoad event to it
				_nul = findDisplay 54 displayAddEventHandler [ "Unload", {
					//Get the exit code
					_exitCode = param[ 1 ];
					
					//1 = ok, 2 = cancel or Escape was pressed
					if ( _exitCode isEqualTo 1 ) then {
						
						//Did we place a marker in the border marker
						if ( ( player getVariable "insertPos" ) inArea "border" ) then {
							hint "You placed a marker inside the Area";
						}else{
							hint "You placed a marker outside the Area";
						};
					};
				}];
			};	
		};
	}];
};


openMap true;
hint "Place a marker either inside or outside the area shown";
_nul = [] call TAG_fnc_createSelectionMarker;
_nul = [] spawn TAG_fnc_waitForPlayerInput;

        waitUntil {!(_mks isEqualTo allMapMarkers)};
        if (count allMapMarkers > 0) then {
          _mk = allMapMarkers select (count allMapMarkers - 1);
          if (_mk inArea myTrigger) then { < do what you want > };
        };
        _mks = allMapMarkers;
      };
    };
  };
}];

Pierre: Yeah that's exactly what i done, as you told me to do, but the script doesn't recognize the area or the trigger variable name, I don't know why.

So i tried what Larrow posted, and finally succeeded! Pierre's way was easier to edit the zone but this isn't a big deal.

 

Thanks to both of you!
