Syntax needed
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

Examples

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];
