Description

Description:
Creates a new map marker at the given position. The marker will be created for every connected player as well as all JIP players. The marker name has to be unique; the command will be ignored if a marker with the given name already exists.
⚠
The marker will be visible only once at least markerType has been defined:
_marker = createMarker ["markername", player]; // Not visible yet. _marker setMarkerType "hd_dot"; // Visible.
ⓘ
If the marker position is given in 3D format, the z-coordinate is stored with the marker and will be used when the marker is passed to commands such as createVehicle, createUnit, createAgent, createMine or setVehiclePosition.
When a marker is manually placed in the editor, z is always 0, which means the marker is placed on the ground. But when the player places a marker on the map in game, it is placed at sea level, so the z-coordinate of that marker is -getTerrainHeightASL markerPos <USERMARKER>.
ⓘ
Multiplayer optimisation: Global marker commands always broadcast the entire marker state over the network. As such, the number of network messages exchanged when creating or editing a marker can be reduced by performing all but the last operation using local marker commands, then using a global marker command for the last change (and subsequent global broadcast of all changes applied to the marker).
Groups:
Markers

Syntax

Syntax:
createMarker [name, position, channel, creator]
Parameters:
name: String The marker's name, used to reference the marker in scripts.
position: Array or Object - Position2D, PositionAGL or Object. In case of object, the object's PositionWorld is used.
channel (Optional): Number (See also Channel IDs) - The marker channel for MP (Template:since).
creator (Optional): Object - The marker creator for MP (Template:since).
Return Value:
String

Examples

Example 1:
_marker1 = createMarker ["Marker1", position player];
Example 2:
_marker2 = createMarker ["Marker2", player]; // since Arma 3 v1.50

createMarker accepts an object as position parameter as well (A3 - 1.50.131969). You could try this with the following code (both SP/MP) _markerstr = createMarker ["markername", player]; _markerstr setMarkerShape "RECTANGLE"; _markerstr setMarkerSize [100, 100];

In Arma 3, one can create markers which are deletable by the user by prefixing the name with `_USER_DEFINED`. Example: createMarker "_USER_DEFINED someMarkerName"

Passing object as argument for position may produce slightly different position than when explicitly obtaining object position via position commands, as in createMarker ["marker1", _obj] may slightly differ from createMarker ["marker1", ASLtoAGL getPosASL _obj] This is because when object passed as position, the raw getPosWorld is used createMarker ["marker1", ASLtoAGL getPosWorld _obj] will produce identical result in this case, but may not be what is required

Arma 3 logo black.png1.92 There is a new function with which you can create a marker with all settings applied in one step: BIS_fnc_stringToMarker and BIS_fnc_stringToMarkerLocal
