Syntax:: lineIntersects [begPos, endPos, objIgnore1, objIgnore2]
Parameters:: begPos: PositionASL
: endPos: PositionASL
: objIgnore1: Object - (Optional, default objNull) object to ignore. When testing intersection from an object/unit/vehicle, pass that object here to prevent intersection inside of the object
: objIgnore2: Object - (Optional, default objNull) 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
Return Value:: Boolean - true if an intersection happens with an object (not with terrain)

Example 1:: private _hasStraightLineToChopper = lineIntersects [eyePos player, aimPos chopper, player, chopper];
