[TUTORIAL] How to use Public Variables

igoooor · January 8, 2015

good catch. always nice to have code review. I'll edit the samples so they are correct

you did the same error "_packet = _this select 0;" in lesson 3

And also in lesson 3, I think this is not correct:

PV_EventStatusClient = [Dayz_Epoch_Event_Running];
publicVariable "Dayz_Epoch_Event_Running";

and should be:

PV_EventStatusClient = [Dayz_Epoch_Event_Running];
publicVariable "PV_EventStatusClient";

right ? You did it twice this one ;)

Edit:

I just saw:

        private ["packet","_sender","_status","_logString","_isAdmin",];
        _packet = _this select 0;

see "packet" and "_packet" ? ^^

ok, I think I got them all. If you see any more let me know.

Hey bud, great thread! making some form of event system using this right now and having some issues with this section of code

// admin menu
if (_isAdmin) then {
    if((speed player <= 1)) then {
        if (s_player_admin_option < 0) then {
			s_player_admin_option = player addaction[("<t color=""#E65C00"">" + ("Admin Menu") +"</t>"),"event\AdminMenu.sqf","",5,false,true,"", ""];
        };
    } else {
        player removeAction s_player_admin_option;
        s_player_admin_option = -1;
    };
};

// player TP menu
if((speed player <= 1) && Dayz_Epoch_Event_Running) then {
	if (s_player_event_option < 0) then {
		s_player_event_option = player addaction[("<t color=""#FF0000"">" + ("-- EVENT ACCESS --") +"</t>"),"event\PlayerMenu.sqf","",5,false,true,"", ""];
	};
} else {
	player removeAction s_player_event_option;
	s_player_event_option = -1;
};

Long story short, no options show on scroll wheel unless i'm looking at a trader? Not tried this with other players yet but i assume it'd be the same results

EDIT: It doesn't show options unless you're looking at any object

this is weird, could you show us the surrounding lines where you put this code in your server_functions.sqf?

Its supposed to be in fn_selfActions :P but anyhow here is how i'm using it right not, tried removing the player speed line to see if helped but no joy, i've placed it pretty much at the very top with all my other custom actions are

This is a weird one to be honest :L

EDIT: NVM fixed it, I had

player removeAction s_player_admin_option;
s_player_admin_option = -1;
player removeAction s_player_event_option;
s_player_event_option = -1;

at the bottom of self act, the times i make derps like this :L

Hey, I saw your tutorial on publiceventhandlers, but I just can't seem to get it well enough to apply it to my script.

I want players to hear my player groan when he is playing possum. (from superfunmenu)

As it is now, only client can hear the groan.

I was hoping you could help me with the basics of getting other players to hear/see my desired sounds/animations.

Thanks man.

I was hoping you could help me with the basics of getting other players to hear/see my desired sounds/animations.

Thanks man.

What you want to do is define a PVEH on the clientside (most likely in the init.sqf or a sqf file called from that) that when fired off, plays a sound.

How you fire it off is the tricky part as you probably only want people in say a 30m radius to hear the sound. You could be lazy and just fire it off to everyone.

So here's how I would do it quick and dirty. Note, there is probably a better way to do this but its monday...

So, you need 2 pveh.

1. Serverside PVEH to get our call from our player and send to other players

2. Clientside PVEH to actually play the sound.

// Serverside PVEH (Init this in your server.pbo)
if (isDedicated) then {
	// expects [Player,Radius]
	"PVEH_PlaySoundServer" addPublicVariableEventHandler {
		private["_packet", "_sender", "_radius", "_playersToSend"];
		_packet = _this select 1;
		_sender = _packet select 0;
		_radius = _packet select 1;
		
		_playersToSend = nearestObjects [_sender, ["CAmanBase"], _radius];
		
		{
			_clientID = owner _x;
			PVEH_PlaySoundClient = [];
			_clientID publicVaribleClient "PVEH_PlaySoundClient";
			
		} forEach _playersToSend;	
	};
};


// Clientside PVEH (init this in your mission.pbo)
if (!isDedicated) then {
	// expects []
	"PVEH_PlaySoundClient" addPublicVariableEventHandler {
		// play sound code goes here	
	};
};

Now please note, that the "get players within raidus" code is probably inefficient and probably buggy. I'm sure there is a better way to do this and you are free to look into that part, I just wrote this up real quick to give you an idea on how you can do this.

edit: sorry I forgot, somewhere in your code to kick this off, you will need to call a publicVariableServer command to kick it off like this:

PVEH_PlaySoundServer = [player,30]; // [player,radius]
publicVariableServer "PVEH_PlaySoundServer";

computermancer · March 23, 2015

Sweet, trying it now, thanks man, Ill edit this with the results :wub:

computermancer · March 23, 2015

Ran into an issue. I get this in my RPT

PVEH_PlaySoundClient = [];

_clientID publicVaribleClient "PVEH_PlaySoundClien>

12:15:59 Error position: <publicVaribleClient "PVEH_PlaySoundClien>

hambeast · March 23, 2015

can you pate your TEST/init.sqf ?

computermancer · March 23, 2015

// Serverside PVEH (Init this in your server.pbo)
if (isDedicated) then {
	// expects [Player,Radius]
	"PVEH_PlaySoundServer" addPublicVariableEventHandler {
		private["_packet", "_sender", "_radius", "_playersToSend"];
		_packet = _this select 1;
		_sender = _packet select 0;
		_radius = _packet select 1;
		
		_playersToSend = nearestObjects [_sender, ["CAmanBase"], _radius];
		
		//_playersToSend = _sender nearEntities [["man"],_radius];
		
		{
			_clientID = (owner _x);
			PVEH_PlaySoundClient = [];
			_clientID publicVaribleClient "PVEH_PlaySoundClient";
			
		} forEach _playersToSend;	
	};
};

hambeast · March 23, 2015

can you try throwing in this between the _clientID = and PVEH at line 15/16:

diag_log format["_clientID: %1", _clientID];

this should make it spit out the clientID of whatever the object is... I have a suspicion that it is picking up AI and trying to pass them the PVAR, will probably need to tweak that part a bit.

computermancer · March 23, 2015

lol, ok, I think I know how to eliminate AI, i have an ESP admin tool that eliminates AI by requireing pUID != "";

hambeast · March 23, 2015

see if you can throw that in there as that might be causing the error. I looked at the code and nothing pops out at me as a syntax error...

idk you could try setting PVEH_PlaySoundClient = 0;

maybe its angry about an empty array?

computermancer · March 23, 2015

Haha, maybe, I will try that.... here is what I have so far..

// Serverside PVEH (Init this in your server.pbo)
if (isDedicated) then {
	// expects [Player,Radius]
	"PVEH_PlaySoundServer" addPublicVariableEventHandler {
		private["_packet", "_sender", "_radius", "_playersToSend"];
		_packet = _this select 1;
		_sender = _packet select 0;
		_radius = _packet select 1;
		
		_playersToSend = nearestObjects [_sender, ["CAmanBase"], _radius];
		
		//_playersToSend = _sender nearEntities [["man"],_radius];
		
		{
			_clientID = (owner _x);
			_eachManPuid = getPlayerUID _x;
			
			if ((_eachManPuid != "")) then {
			
			diag_log format["_clientID: %1", _clientID];
			
			PVEH_PlaySoundClient = 0;
			_clientID publicVaribleClient "PVEH_PlaySoundClient";
			
			};
			
		} forEach _playersToSend;	
	};
};

computermancer · March 23, 2015

It seems to have a problem with this line

_clientID publicVaribleClient "PVEH_PlaySoundClient";

13:06:52 Error in expression <];

PVEH_PlaySoundClient = 0;
_clientID publicVaribleClient "PVEH_PlaySoundClien>
13:06:52   Error position: <publicVaribleClient "PVEH_PlaySoundClien>
13:06:52   Error Missing ;

13:06:52 File mpmissions\epoch.Altis\TEST\init.sqf, line 23

hambeast · March 23, 2015

btw if you are using the stock a3 antihacks, put a file named "skaro.sqf" in your arma3 directory (next to arma3.exe) and you can put code inside of it you want to test out. This only works for clientside code so IDK how helpful it will be for your serverside stuff but you can at least call serverside PVEH's with it.

I think the default keybind is f12 or f11

hambeast · March 23, 2015

hmm... try adding _clientID to the private array at the top of the expression. It could be a locality issue? aside from that I'm not really sure.

I'll have to play with the code tonight and see if I can't generate you a sample pbo to play with

computermancer · March 23, 2015

I'm not using epah, I removed that line just to see if i could get the dialog debug to show and it did

Since I was the only person around for 30 m, this is my clientID i am guessing?

I also loaded in another client and got his client ID and puid as well as mine... not sur ewhere to move from here.

13:26:55 "_clientID: 4"
13:26:55 "_eachManPuid: 76561198000896540"
13:26:55 "_clientID: 5"
13:26:55 "_eachManPuid: 76561198132318240"

hambeast · March 23, 2015

yeah that is your clientid. If you're running infistar, I believe the file is called admin_start.sqf

computermancer · March 23, 2015

So, I can't seem to get the code to work after teh server is triggered.

I can get the diag to display all the code from serverside, such as remotePlayerid, name, uid, etc

but I cant get it to do the next part which is to trigger the clientside code of playing the sound. or even diags :wacko:
