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)

Groups:

Syntax

Syntax:

[object, lodName] intersect [begPos, endPos]

Parameters:

[object, lodName]: Array

object: Object

lodName: String

[begPos, endPos] : Array

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 ArmA3 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.
