Examples

Example 1

private _isInside = [100, 100, 0] inPolygon [[0, 0, 0], [1000, 1000, 0], [1000, 0, 0]];

Example 2

private _markerName = "_USER_DEFINED #0/0/1";

private _xy2DPositions = markerPolyline _markerName;
private _positions = [];

// let's convert these x,y coordinates to "normal" position arrays
for "_i" from 0 to count _xy2DPositions - 1 step 2 do
{
    _positions pushBack [_xy2DPositions select _i, _xy2DPositions select (_i + 1), 0];
};

player inPolygon _positions; // true if in the drawn shape, false if not
