Description

Description:
Finds named selections in object which are in specified LOD, intersected by given section of a line. Return value is in the form of [selection, distance]. Multiple returned arrays are nested within a single array. No intersection returns []. lodName could be one of the following:
  • "FIRE"
  • "VIEW"
  • "GEOM"
  • "IFIRE" - ("I" stands for Indirect, almost the same as FIRE)
  • Arma 3 logo black.png2.02 "PHYSX" - PhysX geometry LOD
Groups:
Math - Geometry

Syntax

Syntax:
[object, lodName] intersect [begPos, endPos]
Parameters:
object: Object
lodName: String
begPos: Array format PositionAGL
endPos: Array format PositionAGL
Return Value:
Array - array of intersections in format: [[selection, distance],...], where
  • selection - name of intersected selection
  • distance - distance from begPos
The results are also sorted, closest selection first

Examples

Example 1:
[_tank, "VIEW"] intersect [[1500, 1500, 2], [1550, 1500, 2]];
Example 2:
sphere = "Sign_Sphere10cm_F" createVehicle [0,0,0]; onEachFrame { _begPos = positionCameraToWorld [0,0,0]; _begPosASL = AGLToASL _begPos; _endPos = positionCameraToWorld [0,0,1000]; _endPosASL = AGLToASL _endPos; _ins = lineIntersectsSurfaces [_begPosASL, _endPosASL, player, objNull, true, 1, "FIRE", "NONE"]; if (_ins isEqualTo []) exitWith {sphere setPosASL [0,0,0]}; _ins select 0 params ["_pos", "_norm", "_obj", "_parent"]; if !(getModelInfo _parent select 2) exitWith {sphere setPosASL [0,0,0]}; _ins2 = [_parent, "FIRE"] intersect [_begPos, _endPos]; if (_ins2 isEqualTo []) exitWith {sphere setPosASL [0,0,0]}; _ins2 select 0 params ["_name", "_dist"]; _posASL = _begPosASL vectorAdd ((_begPosASL vectorFromTo _endPosASL) vectorMultiply _dist); drawIcon3D ["", [1,1,1,1], ASLToAGL _posASL, 0, 0, 0, _name, 1, 0.03, "PuristaMedium"]; sphere setPosASL _posASL; };

The most common LOD is "FIRE", which identifies the most detailled hitbox used for ammunition.

Example (In Arma 3 ver 1.14) display returned arrays on cursor entities:
Sto = []; Fn = { { Sto set [_foreachindex,[cursorTarget, _x] intersect [ASLToAGL eyePos player, screenToWorld [0.5,0.5]]]; } foreach ["FIRE", "VIEW", "GEOM", "IFIRE"]; hintSilent format ["FIRE: %1, VIEW: %2, GEOM: %3, IFIRE: %4", Sto select 0, Sto select 1, Sto select 2, Sto select 3]; }; ["sample_id", "onEachFrame", "Fn"] call BIS_fnc_addStackedEventHandler;
Return FIRE: [something], VIEW: [something], GEOM: [something], IFIRE: [something].

intersect will spam .rpt if passed to it object has no skeleton. Use getModelInfo to filter out those objects.
