Multiplayer: addAction with remote object

[helling3r 10]

Hello,

i try to addAction a script to a object that is created dynamically through the mission, but i have problems with the addAction adding.

I already googled around and im aware that addAction is local only.

Situation in detail:

- Via COIN, a player can create various objects.

- One such object is a barbed wire (object tpye is not important, it also does not work with other objects)

- When the object is created, i broadcast an CBA-GlobalEvent to let all other clients know that the new Object exists. The object is a parameter of that event.

- An event listener executes a local addAction command, attaching the script in question to the newly created object.

- The event gets executed on any client correctly, but it looks like the object itself is not available as parameter. The script is syntactically correct.

Whats supposed:

The event gets executed correctly. However the action does not show up.

I suppose that the object-parameter is not working as object-objects are local too (so i cannot transport them over net as parameter)?

Question:

How can i reference the object in question on other clients when the object is created from a remote client?

Showing your code wouldn't hurt.

For CBA EV's, you pass the variable, and you have to select it with _this just like in a script or function or PVEH's.

Init:

["TAG_ActionEV",{ (_this select 0) addAction ["test","test.sqf"]; }] call CBA_fnc_addEventHandler;

After spawning the vehicle:

["TAG_ActionEV", [_vehicle]] call CBA_fnc_globalEvent;

Can also be done by not using an array:

["TAG_ActionEV",{_this addAction ["test","test.sqf"]; }] call CBA_fnc_addEventHandler;

//later on
["TAG_ActionEV", _vehicle] call CBA_fnc_globalEvent;

Thank you for your reply!

I know how to use CBA events, they serve me well. They cause no trouble, as stated above, the event fires fine client side. its just that _this seems not to be the object that is generated at the other client...

Code:

(Coin executes a special script every time something is build. In case of certain objects, it just raises the event in question).

func_addActionGlobal.sqf (its called by the coin on build)

// CBA EventHandler script for event "global add action"
//
// adds an action.
//

sleep 5; // wait for object to be broadcastet to the net.
_subject = _this select 0;     // The object to which the action should be added
_txt = _this select 1;         // Text entry for the action
_neededGear = _this select 2;  // gear needed for action to be present
_script = _this select 3;      // script to execute

diag_log format ["B_Event received: addActionGlobal (%1; %2)", _txt, _script];

// TODO: Only add action when needed gear-item is present in gear. (addAction condition? If clause here?)
_subject addAction [_txt, _script];

When building, my RPT confirms, the event handler script is called:

"B_Event received: addActionGlobal (Cut wire; scripts\cutRazorWire.sqf)"

Just a quick reply: adding it using a globalEvent is the same.

Both solutions wont work even in singleplayer.

Heureka!

This now works - why i have no clue:

(the code is contained in coin_onconstruct.sqf and called via the BIS_COIN_onconstruct handle)

// Razor Wire
if (_build_class == "Fort_RazorWire") then {
// add action on every client to remove the wire.
// TODO: Only add action when ACE_WireCutter is present in gear. (addAction condition?)

_globalCode = {
	_wireObj = _this select 0;
	waituntil {!(isNull _wireObj)};
	diag_log "[DEF-COIN] added global action to freshly built Fort_RazorWire";
	_wireObj addAction ["Cut wire", "scripts\cutRazorWire.sqf"];
};
[-2, _globalCode, [_build_obj]] call CBA_fnc_globalExecute;
};

_txt needs to be a string for addAction, but your RPT seems to indicate it's an object? or something? Basically missing " " around the Cut Wire part.

Hi, no thats not the problem; the RPT text is coming from an format'ed string. The code used previously correctly passed the _subject variable.

Nonetheless its working now (i edited the posting above, see the code there), i used a globalExecute.

Thank you very much for your input!

You didn't show us how you sent the event :). That's also a global execute, not an event handler. (Technically this an EV, but you're sending code instead of arguments)

You don't add EV's with globalEvent, they trigger the EV :).

You didn't diag_log the subject.

Hello,

yes, because the eventing was not the problem. The problem was the execution of the addAction noit having the desired effect. Because of that i thought it was irrelevant how the event is defined and fired.

The event handler script itself is posted above, and it is also correctly executed (meaning: event is risen successfully and also catched nd processed).

However, now its replaced by an globalExecute and now it works fine. I think there was some problem with the locality of "_this" (maybe the cba eventing stuff transforms the type of the parameters somehow).

Well it works just fine for me.

// init.sqf
["TAG_actionEV",
{
_subject = _this select 0;     // The object to which the action should be added
_txt = _this select 1;         // Text entry for the action
_neededGear = _this select 2;  // gear needed for action to be present
_script = _this select 3;      // script to execute

diag_log format ["B_Event received: addActionGlobal (%1; %2)", _txt, _script];

// TODO: Only add action when needed gear-item is present in gear. (addAction condition? If clause here?)
_subject addAction [_txt, _script];
}] call CBA_fnc_addEventHandler;

//testev.sqf, called from radio alpha
_veh = "AH1Z" createVehicle (getPos player);
["TAG_actionEV", [_veh,"Test action",nil,"myAction.sqf"]] call CBA_fnc_globalEvent;

//myAction.sqf
hint "works";
