Blitzen88 16 Posted January 20, 2023 Having some issues with an AI Hunt/Stalk script that I created. The script uses the BIS_fnc_groupvehicles function to determine if the stalking group has a vehicle. However, I’m getting an error related to this function but I don’t know what I am doing wrong. The error I’m getting is: Quote [BIS_fnc_groupvehicles] Parameter GROUP must be not be null, (OBJECT OR GROUP) required Steam Screenshot of Error (Bottom of Screen) Script: Spoiler /*=================================================================== Arma III - AI Hunt Created by Blitzen ===================================================================== * Script forces AI "hunters" to "hunt" other units by placing a movement waypoint on the location "hunted" group's location * Script can restrict vehicle/infantry groups to only hunt enemy vehicle/infantry groups. Restrictions can also be turned off (ie vehicle groups can hunt infantry groups) * Script will wait a period of time before re-scanning for enemy groups if no groups are found * Script will ignore aircraft and vanilla artillery units * Parameters: 1. Group Leader - Squad leader of the group which will hunt enemy targets 2. Target Filtering - Whether or not vehicle/infantry groups should only hunt vehicles/infantry. True for restrictions, False for no restrictions 3. Hunt Player - Whether or not the hunter will only target the player. Friendly units will still hunt enemy groups. 4. Scan Distance - How far the group will look for targets 5. Scan Delay - How long the script will wait to re-scan for targets if no targets are found 6. Waypoint Delay - How quickly the hunter group's waypoint will update * Call with (Unit Init): [This, True, False, 1000, 40, 30] execVM "Scripts\AI\AI_Hunt.sqf" * Call with (Spawn Module): [leader (_this select 0), True, False, 1000, 40, 30] execVM "Scripts\AI\AI_Hunt.sqf" ===================================================================*/ //Define Input Variables _GroupLeader = _this select 0; _Group = group _GroupLeader; _HuntType = _this select 1; _HuntPlayer = _this select 2; _ScanDistance = _this select 3; _ScanDelay = _this select 4; _WaypointDelay = _this select 5; //Define additional Variables _GroupVehicles = [_Groupleader, true] call BIS_fnc_groupvehicles; _ExcludedUnitTypes = [ "O_MBT_02_arty_F", "B_MBT_01_arty_F", "B_MBT_01_mlrs_F", "I_LT_01_AA_F", "B_AAA_System_01_F", "B_SAM_System_03_F", "B_APC_Tracked_01_AA_F", "I_Mortar_01_F", "B_Mortar_01_F", "O_APC_Tracked_02_AA_F", "O_SAM_System_04_F", "O_Mortar_01_F" ]; //Create Variables to avoid scoping issues _nearestEnemyInfantry = []; _nearestEnemyVehicles = []; _nearestEnemiesCombined = []; _Hunted = []; //Get an array of enemy infantry groups _nearestMen = nearestObjects [getpos _GroupLeader, ["Man"], _ScanDistance]; { if ( (side _x getFriend (side _GroupLeader)) < 0.6 && {side _x != CIVILIAN} && ( {isNull objectParent _x} foreach units group _x) ) then { _nearestEnemyInfantry = _nearestEnemyInfantry + [_x]; }; } forEach _nearestMen; //Get an array of enemy vehicle groups _nearestVehicles = nearestObjects [getpos _GroupLeader, ["LandVehicle"], _ScanDistance]; { if ( (side _x getFriend (side _GroupLeader)) < 0.6 && {side _x != CIVILIAN} && !( _x isKindOf "staticWeapon") && !(typeof _x in _ExcludedUnitTypes) ) then { _nearestEnemyVehicles = _nearestEnemyVehicles + [_x]; }; } forEach _nearestVehicles; //Combine enemy Infantry and Vehicle arrays {_nearestEnemiesCombined append _x} foreach [ _nearestEnemyInfantry, _nearestEnemyVehicles ]; //"Filter" targets based upon input if (_HuntType) then { //Group has a vehicle - Hunt enemy vehicles if (count _GroupVehicles > 0) then { _Hunted = _nearestEnemyVehicles select 0; }; //Group does NOT have a vehicle - Hunt enemy infantry if (count _GroupVehicles == 0) then { _Hunted = _nearestEnemyInfantry select 0; }; } else { _Hunted = _nearestEnemiesCombined select 0; }; //Whether or not enemy groups should hunt the player's group if ( (_HuntPlayer) && !(side _Group == playerSide) ) then { _Hunted = player; }; //Start Movement Cycle _Go = True; while {_Go} do { if ( isNil "_Hunted" ) exitwith {_Go = False}; if (({alive _x} count units _Group) == 0) exitwith {_Go = False}; if (({alive _x} count units group _Hunted) == 0) exitwith {_Go = False}; if ( _Hunted distance _GroupLeader >= _ScanDistance ) exitwith {_Go = False}; for "_i" from count waypoints _Group -1 to 0 step -1 do { deleteWaypoint [_group, _i] }; _GroupWp = _Group addWaypoint [leader group _Hunted, 20]; _GroupWp setWaypointType "MOVE"; _GroupWp setWaypointBehaviour "AWARE"; _GroupWp setWaypointCombatMode "GREEN"; _GroupWp setWaypointSpeed "NORMAL"; Sleep _WaypointDelay; }; //End Movement Cylce - Hunted or Hunter group is dead //Re-Exec the script if Hunters still exist if ( ( {alive _x}count units _Group ) > 0 ) then { sleep _ScanDelay; [leader _Group, _HuntType, _HuntPlayer, _ScanDistance, _ScanDelay, _WaypointDelay] execVM "Scripts\AI\AI_Hunt.sqf"; }; Share this post Link to post Share on other sites
