Description:: Returns objects intersecting with the virtual line from begPos to endPos. By default resulting array of intersecting objects is unsorted. To sort by distance set sortByDistance param to true.
⚠
Doesn't work under water. Max hardcoded distance is 1000m.
Groups:: Math - Geometry

Syntax:: lineIntersectsWith [begPos, endPos, objIgnore1, objIgnore2, sortByDistance]
Parameters:: [begPos, endPos, objIgnore1, objIgnore2, sortByDistance]: Array
: begPos: PositionASL - virtual line start
: endPos: PositionASL - virtual line end
: objIgnore1: (optional) Object - object to ignore. When testing intersection from an object/unit/vehicle, pass that object here to prevent intersection inside of the object.
: objIgnore2: (optional) Object - another object to ignore. When testing intersection of a line between two objects, pass the second object here to prevent intersection inside of it being reported
: sortByDistance: (optional) Boolean - true: Sort by distance => furthermost object first, closest object last; false: unsorted
Return Value:: Array - intersecting objects

Example 1:: _objects = lineIntersectsWith [eyePos player, AGLtoASL screenToWorld [0.5,0.5]];
Example 2:: Sort by distance: _objects = lineIntersectsWith [eyePos player, AGLtoASL screenToWorld [0.5,0.5], objNull, objNull, true];
Example 3:: Ignore objects: _objects = lineIntersectsWith [eyePos player, aimPos chopper, player, chopper];
