Setting an area around the aircraft carrier landing cables [SOLVED]

Recommended Posts

Hey, tudo bem com voc√™?¬†ūü§ď

 

Gentlemen, I've read the Jets DLC functions to understand how the USS Freedom Carrier accepts landings by planes with tailhook, 'cause I wanna print out a hintSilent "You did it!", but only and precisely at that cables area (X, Y, Z), even if the Mission Editor changes the carrier's spot.

    Description:
    Aircrfat carrier arrest/recovery function for USS Freedom aircraft carrier

    Exucution:
    Call the function via user-action or script for any compatible fixed wing aircrfat
    [this] spawn bis_fnc_aircraftTailhook;

    Requirments:
    - Compatible aircrfat must have an animation for arrest/tail hook selection defined in CfgCehicles and modeled in 3D model (model.cfg)
    - Compatible aircrfat must have a memory point for cable attach position

    example of cfgVehicles subclass definitions;

        tailHook = true;                                                                            Allow to land on carrier
        class CarrierOpsCompatability
        {
            ArrestHookAnimationList[] = {"tailhook", "tailhook_door_l", "tailhook_door_r"};            List of animation played to animate tailhook. Defined in model.cfg (type user)
            ArrestHookAnimationStates[] = {0,0.53,1};                                                Tailhook animation states when down, hooked, up.
            ArrestHookMemoryPoint = "pos_tailhook";                                                    TailHook memory point in plane model.p3d
            ArrestMaxAllowedSpeed = 275;                                                            Max speed km/h allowed for successful landing
            ArrestSlowDownStep = 0.8;                                                                Simulation step for calcualting how smooth plane will be slowed down.
            ArrestVelocityReduction = -12;                                                            Speed reduced per simulation step

        };

    Parameter(s):
        _this select 0: mode (Scalar)
        0: plane/object


    Returns: nothing
    Result: Aircrfat after touch down on carrier deck will be dynamicly slowed down. If speed willbe above 275 km/h (suggested and configured on vanilla assets) wire snap will be simulated.
        Aircrfat will come to full stop in 155-175 m

How can I smartly track that area to print out the message with no triggers and hidden objects dropped around?

nearestObjects [_plane,["Land_Carrier_01_Hull_08_1_F"],50] isNotEqualTo []

 

That's for presence in arresting gear area... That doesn't mean you didn't crash, or bolter (not sure it's possible in Arma).
Of course, the plane stops farther: You can try with   "Land_Carrier_01_Hull_05_1_F" and speed 0,   or test all parts in config viewer / "cfgVehicles" starting with "Land_carrier_01..."

Wait for planes hook animation to be in _planeHookDownAnimState.

Then check the state of the plane's hook animation to see if it changes to either _planeHookCaughtAnimState or _planeHookUpAnimState.

If it's in _planeHookCaughtAnimState you know it has been caught and possibly landed, maybe also check alive, speed, height above deck and possibly distance to _carrierWirePosition of the plane to make sure it didn't crash, break the wire or abort the landing?

All the bits needed can be found in \a3\functions_f_jets\functions\aircraft\fn_aircrafttailhook.sqf

Just coming back to share the solution is present in my Vehicle Overhauling Script:


Thanks, @pierremgi, and @Larrow for the ideas.


Resuming the solution:
Instead of looking for cables in the aircraft carrier asset, reading the Jets DLC functions, I realized that the USS Freedom asset is composed of 3 smaller assets. I've stored your asset classnames in a list, and as soon as a plane approaches any classname within the list, the plane gets the action to rearm, repair, and refuel.

 

fn_VO_parameters.sqf:

VO_assetsRangeChanger = ["Land_Carrier_01_hull_08_1_F","Land_Carrier_01_hull_07_1_F","Land_Carrier_01_hull_06_1_F"]; 

 

fn_VO_globalFunctions.sqf

THY_fnc_VO_isStationRangeChanger = {
	// This function checks if the current station has the ability to change its service range to attemp planes only. If so, the range is increase where _servRng != _currentRng.
	// Returns the integer range _currentRng.

	params [["_stat", objNull], ["_veh", objNull], ["_hasRngChanger", false], ["_servRng", 20]];
	private ["_rangeChanger", "_currentRng", "_statType"];

	_rangeChanger = 80;
	_currentRng = _servRng;

	if ( !_hasRngChanger ) exitWith { _currentRng  /* Returning. */ };
	
	// Handling Errors:
	if (_stat isEqualTo objNull) exitWith {if (VO_debugMonitor) then {systemChat "VO > THY_fnc_VO_isStationRangeChanger error: needs a station as parameter."; sleep 15}};
	if (_veh isEqualTo objNull) exitWith {if (VO_debugMonitor) then {systemChat "VO > THY_fnc_VO_isStationRangeChanger error: needs a vehicle as parameter."; sleep 15}};

	_statType = typeOf _stat;

	// Range-Changer trigger to action:
	if ( _veh isKindOf "Plane" AND _statType in VO_assetsRangeChanger ) then 
	{ 
		if ( _servRng < _rangeChanger ) then { _currentRng = _rangeChanger };

		if ( VO_debugMonitor AND (_currentRng >= _rangeChanger) AND ((_veh distance _stat) <= _currentRng) ) then
		{ 
			systemChat format ["DEBUG: station %1 is a RANGE-CHANGER, its service range increase to %2m for Planes.", _statType, _currentRng];
			sleep 3;
		};
	};
	
	_currentRng  // returning.
};

 

Cheers,
