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.

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.
The alternative syntax gets the position given distance and heading away from provided object or position - the equivalent of BIS_fnc_relPos.
Groups:
Positions

Syntax 1

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

Syntax 2

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

Syntax 3

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

Examples

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