Issues with variables on multiplayer (client-server)

[Icaruk 14]

Hi, I have a problem about variables and multiplayer, here is my example:

init.sqf

publicVariable "A","points";
_null = [] execVM "engine.sqf";

engine.sqf

if (isServer) then {
A = 0;
publicVariable "A";
points = 0;
publicVariable "points";
};


if (isServer) then {
while {true} do {
	if (A == 1) then {
		points = points +1;
		sleep 1;
	}

Okay, the problem is when player1 has points = 10, maybe player2 has points = 8

Any solutions to this? Thanks

Bump! T_T

Question are the players on the server at the same time?

Yes, imagine a sector control, with players capturing the base A, and getting points each seconds for it.

Are you trying to make different variables with the same name?

You can use setVariable command on player or some other objects.

When a player captures a base via trigger, A = 1.

So, if A == 1, points will get a +1 each second. There are 2 different variables.

[champ-1 40]

if (A == 1) then {
points = points +1;
publicVariable "points";
sleep 1;
}

I think you need to broadcast this value over network every time.

This:

if (isServer) then {
while {true} do {
	if (A == 1) then {
		points = points +1;
		sleep 1;
	}

works nice, the problem is that at some point of the game, some players will have 1000 points, and others will have 1200 others 800 others 1100...

Command "publicVariable" broadcasts current value of given variable over the network. In this loop you get variable "points" and add 1 point to it. But this variable has old value and haven't been synced with other players. That's why you need to broadcast it every time or at least sometimes.

So It would be like this?

init.sqf

publicVariable "A","points";
_null = [] execVM "engine.sqf";

engine.sqf

if (isServer) then {

	while {true} do {
	if (A == 1) then {
		points = points +1;
		publicVariable "points";
                       sleep 1;
	}

What about this?

init.sqf

publicVariableServer "A","points";
_null = [] execVM "engine.sqf";

Using publicVariableServer you are telling the server to keep track of the updates for the variable and no client will receive the updated variable information. Using publicVariable after the variable on the server has been updated is the right way to go. But caution must be used when using the publicVariable frequently. It can severely lag other parts of the game. How often is A going to be 1? Maybe a point for every 3 seconds a player is in the sector?

This is my script atm:

if (isServer) then {


A = 0;
publicVariable "A";
B = 0;
publicVariable "B";

pointsBLU = 0;
publicVariable "pointsBLU";
pointsRED = 0;
publicVariable "pointsRED";


};	




while {true} do
{
call compile preprocessFileLineNumbers "scripts\hud\hud_update.sqf";			


	if (A == 1) then {
		pointsBLU = pointsBLU + 1;
		publicVariable "pointsBLU";
		"amrk" setMarkerColor "ColorBlue";
	};
	if (A == 2) then {
		pointsRED = pointsBLU + 1;
		publicVariable "pointsRED";
		"amrk" setMarkerColor "ColorRed";
	};
	if (B == 1) then {
		pointsBLU = pointsBLU + 1;
		publicVariable "pointsBLU";
		"bmrk" setMarkerColor "ColorBlue";
	};
	if (B == 2) then {
		pointsRED = pointsBLU + 1;
		publicVariable "pointsRED";
		"bmrk" setMarkerColor "ColorRed";
	};
};
sleep 1;	
};

A = 1 means that this base is blue, A = 2 means that this base is red, same with B. So they will just change when a team can capture the base.

BTW is possible to put just the end of the script like this?

		};
};
publicVariable "pointsBLU";
publicVariable "pointsRED";
sleep 1;	
};
