teamswitch team switch - losing supports

pierremgi · May 19, 2014

Hi all,

Team switching is one of the weirdest feature in Arma. If you are playing in SP, with several switchable units, some behaviors can be lost.

If you switch, you can loose all supports (BI standard support modules).

Reproducible, Vanilla, 3den:

Add units: player + playable ones

Add an artillery (the support type doesn't matter, it's just an example)

Add the artillery provider module

add the requester module

link the artillery to the provider module, the provider to the requester module, the requester module to all switchable (playable in 3den) units.

Preview

Starting as player (the player unit in 3den), gives you the artillery support. No problem.
Starting "as character" from any other playable unit does the trick also. No problem.

But, each time you press "U" (or whatever key for switching menu) and you choose another unit, the support menu disappear.

NB 1: No matter the method used: editor or scripted links with BIS_fnc_addSupportLink, the supports are lost on team switching. Only the first unit played at start can call supports.

NB 2: a little workaround, tested but not guaranteed:

addMissionEventHandler ["teamSwitch", {
   BIS_requesterFSM = nil;
  [yourRequestModuleName] execVM "A3\modules_f\supports\init_requester.sqf";
}];

Now if you switch, the support works.... A remaining point I failed to correct: At your first support call after switching, a hint message will say: "provider not available". Which is wrong. The support works.

No, it doesn’t work and there’s an error.

And here's what happens when I use your script "BI supports depending on radio backpack"

pierremgi · May 19, 2014

Your error is unreadable.

Which script? A link could help. I have tons of scripts, more or less adapted to peculiar requests, most of the time.

@Brahma281 I have something from my ISIL Foothold mission you can use, Pierremgi helped me with this

a while back. Basically put this code in your init.sqf

TransferProviders = {

	_oldUnit = _this select 0;
	_oldProviders = _oldUnit getVariable ["BIS_SUPP_allProviderModules",[]];
	_HQ = _oldUnit getVariable ["BIS_SUPP_HQ",objNull]; 

	if (isNil {player getVariable "BIS_SUPP_HQ"}) then { 
		if ((count _oldProviders) > 0) then {
			{
				_providerModule = _x;
				{
					if (typeOf _x == "SupportRequester" && _oldUnit in (synchronizedObjects _x)) then {
						[player, _x, _providerModule] call BIS_fnc_addSupportLink;
					};
				}forEach synchronizedObjects _providerModule;
			}forEach _oldProviders;
		};

		player setVariable ["BIS_SUPP_transmitting", false];
		player kbAddTopic ["BIS_SUPP_protocol", "A3\Modules_F\supports\kb\protocol.bikb", "A3\Modules_F\supports\kb\protocol.fsm", {call compile preprocessFileLineNumbers "A3\Modules_F\supports\kb\protocol.sqf"}];
		player setVariable ["BIS_SUPP_HQ", _HQ];
	};

	{
		_used = _oldUnit getVariable [format ["BIS_SUPP_used_%1",_x], 0];
		player setVariable [format ["BIS_SUPP_used_%1", _x], _used, true]
	} forEach [
		"Artillery",
		"CAS_Heli",
		"CAS_Bombing",
		"UAV",
		"Drop",
		"Transport"
	];
};


_thread = [] spawn {
	_unit = player;
	while {true} do {
		waitUntil {_unit != player };
		hintSilent " Player has changed";
		[_unit] call TransferProviders;
		_unit = player;
	};
};

When you die all your supports like calling for mortar support, or cas, or even a heli, will transfer

to the next playable unit you switch to.

Ah, Thanks @Gunter Severloh I'm a little bit lost in my own library. 🤭

I figured it out and made your code work without an error,but the same bug appears as shown in the video

Here is this script As shown in the video, if the first unit calls support, and then another one calls it, an bug is obtained.

I believe it has something to do with "provider not available"

Yes, thank you,this code works perfectly without the "provider not available" bug. But I would like to have the same script depending on the radio backpack as the one I posted above

That's a different problem.

Once your "team switch" weird BI uncompleted feature is cured by the script above, feel free to add a new script for backpack radios like:

in initPlayerLocal.sqf

MGI_radios = ["UNS_alice_FR","UNS_USMC_RTO","UNS_USMC_RTO2","UNS_ARMY_RTO","UNS_ARMY_RTO2","UNS_SF_RTO","tf_rt1523g","tf_anprc155","tf_mr3000","tf_bussole","tf_anarc210","tf_anarc164","tf_mr6000l"];  // or what ever you want as backpack....

player spawn {
  _unit = _this;
  while {true} do {
    waituntil {sleep 2; (backpack _unit in MGI_radios or (backpack _unit) isKindOf "TFAR_bag_base")};
      publicVariable "count_drop";
      [_unit,req,cas1] call BIS_fnc_addSupportLink;
      [_unit,req,drop_veh] call BIS_fnc_addSupportLink;
      [_unit,req,arty1] call BIS_fnc_addSupportLink;
      waituntil {sleep 2; (!(backpack _unit in MGI_radios) && !((backpack _unit) isKindOf "TFAR_bag_base"))};
     [req,_unit] call BIS_fnc_removeSupportLink;
  };
};

Just adapt req cas1 arty1 drop_veh to your module names...

Yes, it helped with the provider bug,but another problem happened

Now the support call depends on whether the "player" unit has an RTO backpack or not, if "playable" unit removes the backpack from their inventory, nothing will change

Now it works, flawlessly, like clockwork, without bugs and errors. I am very happy and express my deep gratitude, because I tried to solve this problem on my own for a week,but it didn't work out.

Will this also work in multiplayer?

Storm Rider · July 20, 2018

Thank you very much @pierremgi for this code. It works!

Would you be able to extend this code to also support vehicle types as support requesters?

Yes but you need to add

if (isServer) then {
waitUntil {!(isNull player)};
};

at the top, thats if your hosting your own local server lan, or a dedicated.

See these two pages on what code to add for servers:

pierremgi · May 19, 2014

If you place it in initPlayerLocal.sqf, (SP or MP) it should work as is, in multiplayer... You are in a "player ready" context.

The fact is I don't know exactly in what case your player will lost a "player status" then re-gain it... a return to lobby? On my mind, the initPlayerLocal.sqf is re-run in MP... So probably something smarter to do with player connected/disconnected rather than this loop.

@Storm Rider If I understand your request, you would like to be able to call support when you are in a certain type of vehicle as well as being on foot and carrying a backpack.
You can add an array of vehicle types, different from backpack ones. Say MGI_vehicles = ["B_MRAP_01_hmg_F"......] // case sensitive

The first waitUntil becomes:
waitUntil {sleep 2; (typeOf objectParent player in MGI_vehicles or backpack _unit in MGI_radios or (backpack _unit) isKindOf "TFAR_bag_base") or !isPlayer _unit};
the second one:
waitUntil {sleep 2; ( !(typeOf objectParent player in MGI_vehicles) && !(backpack _unit in MGI_radios) && !((backpack _unit) isKindOf "TFAR_bag_base")) or !isPlayer _unit};
