Description

Description:
Returns objects intersecting with the virtual line from begPos to endPos. By default, the resulting array of intersecting objects is unsorted (see sortByDistance).
ⓘ
  • Does not work under water.
  • Max hardcoded distance is 1000m.
Groups:
Math - Geometry

Syntax

Syntax:
lineIntersectsWith [begPos, endPos, objIgnore1, objIgnore2, sortByDistance]
Parameters:
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];
