Description
- Description:
- Returns list of objects intersected by given line from begPos to endPos.
- Groups:
- Uncategorised
Syntax
- Syntax:
- lineIntersectsObjs [begPos, endPos, withObj, ignoreObj, sortByDistance, flags]
- Parameters:
- begPos: PositionASL - virtual line start
- endPos: PositionASL - virtual line end
- withObj: Object
- ignoreObj: Object
- 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:
Sto = []; Fn = { { Sto 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, NEAREST_CONTACT: %2, ONLY_STATIC: %3, ONLY_DYNAMIC: %4, FIRST_CONTACT: %5, ALL_OBJECTS: %6", Sto select 0,Sto select 1,Sto select 2,Sto select 3,Sto select 4,Sto select 5]; }; ["sample_id","onEachFrame","Fn"] call BIS_fnc_addStackedEventHandler; //Example display objects' array in the middle of the screen sorted by 6 flags

- Distance sorting is relative to object model center, and not intersect position.
