why am i getting this error

Error in expression <* (cos _azi), 0];
}
else
{
_veh = _type createVehicle _pos;
};


_veh setDir _az>
 Error position: <createVehicle _pos;

i am calling spawnvehicle by

for "_i" from 0 to 10 do 
	{

    _grp2 = [];
	_spawn2 = getMarkerPos "E_Patrol";
	_offset2 = [30,50,70,80,120,200,250] call BIS_fnc_selectRandom;
	_offset3 = random 100;
	_prec2 = random 100;
	_exp2 = "(1 - houses) * (1 - houses)";
	_bestplace2 = selectBestPlaces [_spawn2,_offset2,_exp2,_prec2,1];
	_spot4 = _bestplace2 select 0;
	_spot3 = _spot4 select 0;
	_safespawn2 = _spot3 findEmptyPosition [10, 75, "tank"];
	_randomvehicle2 = ["T34_TK_EP1","BRDM2_ATGM_TK_EP1","LandRover_MG_TK_EP1","T72_TK_EP1","ZSU_TK_EP1"] call BIS_fnc_selectRandom;
	_direction2 = random 359;
	[color="#FF0000"]_vehicleCreated =[_safespawn2, _direction2, _randomvehicle2, EAST] call BIS_fnc_spawnvehicle;[/color]
	_vehiclegroup = _vehicleCreated select 2;//group
	[(units _vehiclegroup) select 0, "E_Patrol","spawned","nofollow","random","nowait","delete:",120] execVM "scripts\upsmon.sqf";

	};

This usually happens when you provide invalid argument into createVehicle. Keep in mind that findEmptyPosition might return [] (empty array) if no empty position was found, likely this is the case take this into account.

That code works as written for me.

Try to add

hint format ["%1", _safespawn2];

and notice that findEmptyPosition is not reliable and not always finds position.

[hogmason 2]

So would you know a way i can work around it

[samatra 85]

for "_i" from 0 to 10 do {
_grp2 = [];
_spawn2 = getMarkerPos "E_Patrol";
_offset2 = [30,50,70,80,120,200,250] call BIS_fnc_selectRandom;
_offset3 = random 100;
_prec2 = random 100;
_exp2 = "(1 - houses) * (1 - houses)";
_bestplace2 = selectBestPlaces [_spawn2,_offset2,_exp2,_prec2,1];
_spot4 = _bestplace2 select 0;
_spot3 = _spot4 select 0;
_safespawn2 = [];
_attempts = 10;
while {(count _safespawn2 == 0) && (_attempts > 0)} do {
	_safespawn2 = _spot3 findEmptyPosition [10 + ((10 - _attempts) * 10), 75 + ((10 - _attempts) * 10), "tank"];
	_attempts = _attempts - 1;
}
if(count _safespawn2 == 3) then {
	_randomvehicle2 = ["T34_TK_EP1","BRDM2_ATGM_TK_EP1","LandRover_MG_TK_EP1","T72_TK_EP1","ZSU_TK_EP1"] call BIS_fnc_selectRandom;
	_direction2 = random 359;
	_vehicleCreated =[_safespawn2, _direction2, _randomvehicle2, EAST] call BIS_fnc_spawnvehicle;
	_vehiclegroup = _vehicleCreated select 2;//group
	[(units _vehiclegroup) select 0, "E_Patrol","spawned","nofollow","random","nowait","delete:",120] execVM "scripts\upsmon.sqf";
};
};

Here is how I would do it. Basically it attempts to find safe position 10 times and increases radius and search distance by 10 meters each attempt. And it creates group only if position was found. (You can get rid of all "10 attempts" thing actually and just skip group creation if no position was found)

(I did not test the code, let me know if it will throw an error.)

Cheers mate ill test it when i get home

[hogmason 2]

its spitting this error out mate

Error in expression <, "tank"];
_attempts = _attempts - 1;
}
