[SOLVED] broadcast of variable in variable space of object

[sarogahtyp 1108]

I ve some vehicles with variables in their variable space and I want to have them broadcasted betwenn headless client (HC) and server.

_squad  setVariable["respawtime", 300];

I know that i could set the parameter public to true to broadcast it to all.

_squad  setVariable["respawnable", 300, true];

But thats more network traffic than I need.

Is there a way to use  publicVariableServer and publicVariableClient to broadcast that variable?

 

Or is the variable also transferred if I use setOwner to transfer the ownership between server and HC?

 

Thanks a lot for any advice.

The publicVariable... commands only affect variables in the Mission namespace, not object-variables.

 

So for what you want to achieve you could either put those variables in mission space or make a function for changing the variables and use it with remoteExec.

 

Or is the variable also transferred if I use setOwner to transfer the ownership between server and HC?

I doubt it.

What makes you say that? Are you going to be setting this variable every frame or something like that? If you are setting this value infrequently, the network traffic that you'd be introducing would be negligible.

It adds up quickly.

 

 

Oh anyway, whats the reason to have those variables on both the HC and the server?

 

Would probably be cleaner to handle whatever you're doing only on one or the other. Without transmitting stuff back and forth.

From experience, I can tell you that with simple variables like this, it really doesn't. There is so much information being broadcast all the time just to keep the simulation running; the state of one object variable is nothing by comparison. I still recommend just broadcasting it globally using the optional third parameter of setVariable as this is definitely the most pragmatic solution.

 

But if you really insist...

 

You could use a public variable event handler to achieve your goal: 

 

init.sqf:

if (isServer || (!hasInterface && !isDedicated)) then
{
    var_serverCode = {}; // this variable will serve as a holder for code we want run only on the server and HC
    "var_serverCode" addPublicVariableEventHandler {call (_this select 1)};
};

Now, whenever you want to change your object variable, instead of doing it normally, do this:

_codeToPass = compile format ["%1 setVariable ['respawnable',300]",_squad];
var_serverCode = _codeToPass;
publicVariable "var_serverCode"; // send it to HC or server (whichever one this isn't)
call _codeToPass; // execute code locally

This is overly complicated and totally unnecessary, but there you go.

thank u for ur answers guys i ll think about the whole thing and decide if i choose the solution of dux2.

the code posted at first post was an example only.

my intention is to have all information pinned at objects to easy run needed stuff at HC if it gets reconnected after disconnect.

the main reason is an issue with linux hc/server connection as u can see here:

but u should use google cache to read it cause feedback tracker is down.
