Description

Description:
Returns a list of objects intersected by the line from begPos to endPos.
Groups:
Math - Geometry

Syntax

Syntax:
lineIntersectsObjs [begPos, endPos, ignoreObj1, ignoreObj2, sortByDistance, flags]
Parameters:
begPos: Array format PositionASL - virtual line start
endPos: Array format PositionASL - virtual line end
ignoreObj1: Object - object to ignore
ignoreObj2: Object - object to ignore
sortByDistance: Boolean - true: furthest object first, closest object last; false: unsorted
flags: Number
  • 1 - CF_ONLY_WATER
  • 2 - CF_NEAREST_CONTACT
  • 4 - CF_ONLY_STATIC
  • 8 - CF_ONLY_DYNAMIC
  • 16 - CF_FIRST_CONTACT
  • 32 - CF_ALL_OBJECTS (Usable only with CF_FIRST_CONTACT and it will check one contact per object)
Flags can be combined: 2 + 4 = 6 is CF_NEAREST_OBJECT + CF_ONLY_STATIC
Return Value:
Array of Objects - intersecting objects

Examples

Example 1:
data = []; displayFunction = { { data set [_foreachindex, lineIntersectsObjs [eyePos player, ATLToASL screenToWorld [0.5, 0.5], objNull, objNull, false, _x]]; } forEach [1, 2, 4, 8, 16, 32]; hintSilent format ["ONLY_WATER: %1\nNEAREST_CONTACT: %2\nONLY_STATIC: %3\nONLY_DYNAMIC: %4\nFIRST_CONTACT: %5\nALL_OBJECTS: %6", data select 0, data select 1, data select 2, data select 3, data select 4, data select 5]; }; ["sample_id", "onEachFrame", "displayFunction"] call BIS_fnc_addStackedEventHandler; // example display objects' array in the middle of the screen sorted by 6 flags
