The z height returned changes dynamically with the height of waves beneath the object, if the object is located over sea. The z height returned by [[getPosATL]] and [[getPosASL]] does not change like this. This was tested by continuously retrieving the position of a static object, like the cross in the empty/corpses category, placed over sea or land.

[[getPos]] behaves similar to

but it does not give the same result, therefore

(_obj modelToWorld [0.0, 0.0, 0.0]) is not the same as (getPos _obj).

Introduced with Operation Flashpoint version1.00
  Arguments of this scripting command don't have to be local to the client the command is executed on

Click on the images for descriptions

Introduced in

Game:
Operation Flashpoint
Version:
1.00

Description

Description:
Returns object or location position. If the argument is the object, the return value is in format PositionAGLS. Z value is height over the surface underneath. Since Arma 3 v1.55.133361, an alternative syntax is added that allows to get position given distance and heading away from original object or position, the equivalent of BIS_fnc_relPos

Syntax

Syntax:
getPos object
Parameters:
object: Object
Return Value:
Array - format PositionAGLS

Alternative Syntax

Syntax:
getPos location
Parameters:
location: Location
Return Value:
Array - format [x,y,z], where z is -1 * getTerrainHeightASL at the location

Alternative Syntax 2

Syntax:
origin getPos [distance, heading]         (Since Arma 3 v1.55.133361)
Parameters:
origin: Object, Position2D or Position3D
[distance, heading]: Array
distance: Number - distance from position
heading: Number - in which compass direction
Return Value:
Array - format [x,y,z], where z is land surface in format PositionAGL

Examples

Example 1:
hintSilent str getPos player;
Example 2:
getPos vs. other methods (over sea) diag_log getPos ship; // [2412.01, 6036.33, -0.839965] diag_log getPosATL ship; // [2412.01, 6036.33, 19.4266] diag_log getPosASL ship; // [2412.01, 6036.33, -0.920066] diag_log getPosASLW ship; // [2412.01, 6036.33, -0.865981] diag_log visiblePosition ship; // [2412.02, 6036.33, -0.837952] diag_log visiblePositionASL ship; // [2412.02, 6036.33, -0.91798] diag_log position ship; // [2412.01, 6036.33, -0.839965]
Example 3:
getPos vs. other methods (over land) diag_log getPos car; // [2508.64, 5681.47, 0.0609589] diag_log getPosATL car; // [2508.64, 5681.47, 0.0356369] diag_log getPosASL car; // [2508.64, 5681.47, 71.718] diag_log getPosASLW car; // [2508.64, 5681.47, 71.718] diag_log visiblePosition car; // [2508.64, 5681.47, 0.0609512] diag_log visiblePositionASL car; // [2508.64, 5681.47, 71.718] diag_log position car; // [2508.64, 5681.47, 0.0609589]
Example 4:
Find position 100 metres and 45 degrees from player position:player getPos [100,45];

getPos obj select 2 might return the vertical position above ground level, but for a stacked object, it returns the vertical position above the object beneath it. The same problem exists for getPosASL. There was a discussion thread in the BIS forums which suggested the use of the command modelToWorld instead to get around this issue where an absolute vertical position is required. ArmA Ver 1.02.

You can use getPos and setPos on triggers.
