Detecting if Unit In Building

[Kolmain 6]

Whats the best way to check if a unit is in a building or not?

[jw custom 56]

Not sure how reliable it is but this is from DayZ:

private["_unit1","_building","_type","_relPos","_boundingBox","_min","_max","_myX","_myY","_myZ","_inside"];

_unit1 = _this select 0;

//_building = _this select 1;

_building = nearestObject [player, "HouseBase"];

_type = typeOf _building;

_relPos = _building worldToModel (getPosATL _unit1);

_boundingBox = boundingBox _building;

//diag_log ("DEBUG: Building: " + str(_building) );

//diag_log ("DEBUG: Building Type: " + str(_type) );

//diag_log ("DEBUG: BoundingBox: " + str(_boundingBox) );

_min = _boundingBox select 0;

_max = _boundingBox select 1;

//diag_log ("Min: " + str(_min) );

//diag_log ("Max: " + str(_max) );

_myX = _relPos select 0;

_myY = _relPos select 1;

_myZ = _relPos select 2;

//diag_log ("X: " + str(_myX) );

//diag_log ("Y: " + str(_myY) );

//diag_log ("Z: " + str(_myZ) );

if ((_myX > (_min select 0)) and (_myX < (_max select 0))) then {

if ((_myY > (_min select 1)) and (_myY < (_max select 1))) then {

if ((_myZ > (_min select 2)) and (_myZ < (_max select 2))) then {

_inside = true;

} else { _inside = false; };

} else { _inside = false; };

} else { _inside = false; };

//diag_log ("isinBuilding Check: " + str(_inside) );

_inside

nice one JW, I will have to give that a try!

I use this function here but can be heavy on performance and it's not optimized yet. Works with about 95% accurancy though.

Thanks guys, I was trying to use the bounding box idea!
