intersect

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 v2.02 "PHYSX" - PhysX geometry LOD

Syntax

[object, lodName] intersect [begPos, endPos]

Parameters:

• object: Object
• lodName: String
• begPos: PositionAGL
• endPos: PositionAGL

Returns: Array with [selection, distance]

• selection: String - name of intersected selection
• distance: Number - 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;
};
