Description

Description:

Returns list of intersections with surfaces from begPosASL to endPosASL. If there is ground intersection, it is also included. Works on units. Works underwater. Doesn't return intersection with sea surface. Hardcoded max distance: 5000m.

Syntax

Syntax:

lineIntersectsSurfaces [begPosASL, endPosASL, ignoreObj1, ignoreObj2, sortMode, maxResults]

Parameters:

[begPosASL, endPosASL, ignoreObj1, ignoreObj2, sortMode, maxResults]: Array

begPosASL: PositionASL - virtual line start

endPosASL: PositionASL - virtual line end

ignoreObj1 (Optional): Object - first object to ignore or objNull: Default: objNull

ignoreObj2 (Optional): Object - second object to ignore or objNull: Default: objNull

sortMode (Optional): Boolean - true: closest to furthest, false: furthest to closest. Default: true

maxResults (Optional): Number - Max results to return. -1 to return every result. Default: 1

Return Value:

Array of intersections in format [[intersectPosASL, surfaceNormal, intersectObj, parentObject],...] where:

• intersectPosASL - the actual position where line intersects 1st surface
• surfaceNormal - a normal to the intersected surface
• intersectObject - the object the surface belongs to (could be proxy object)
• parentObject - the object proxy object belongs to (not always the same as intersect object)

Examples

Example 1:

_intersections = lineIntersectsSurfaces [eyePos player, aimPos chopper, player, chopper, true, -1];

Example 2:

arrow = "Sign_Arrow_F" createVehicle [0,0,0]; onEachFrame { _ins = lineIntersectsSurfaces [ ATLToASL positionCameraToWorld [0,0,0], ATLToASL positionCameraToWorld [0,0,1000], player ]; if (count _ins == 0) exitWith {arrow setPosASL [0,0,0]}; arrow setPosASL (_ins select 0 select 0); arrow setVectorUp (_ins select 0 select 1); hintSilent str _ins; };
