execVM for all players

[Vadym Mazur 5]

Good evening. I'm trying to call execVM for the players. Where is the mistake?
fn_init.sqf

{
	if(isPlayer _x) then {
	[_x] execVM "script.sqf";
	};
} forEach allUnits;

script.sqf
 

_unit = (_this select 0);
_unit createDiarySubject ["Hello","Everybody"];

Don't offer to do it:

{
	if(isPlayer _x) then {
	_x createDiarySubject ["Hello","Everybody"];
	};
} forEach allUnits;

The script run to the players upon certain players actions

The mistake is that createDiarySubject requires local argument, therefore you need to execute this command using remoteExec.

To expand on Schatten's answer a little:

A good read for understanding locality can be found in the follow link but you can save that for later: https://community.bistudio.com/wiki/Multiplayer_Scripting#Locality

 

The main takeaway is that any multiplayer session works by multiple machines essentially running their own "version" of the events of the game.

The server is master and there's a fair amount of synching for every computer to share the same state.

At the same time we don't want the entire state of the game to be shared e.g. pressing Escape on one player's computer should not open the pause menu on all other players' computers.

This is why script commands can have local/global arguments (denoted LA/GA respectively) and local/global effect (LE/GE).

 

So createDiarySubject is an LE command, you can see this on the BIKI: https://community.bistudio.com/wiki/createDiarySubject

That means what you are currently doing is adding the diary subject on to all players but only on the computer that executes the code, this is not synced to other computers.

 

To send code to other computers we use remoteExec.

 

// fn_init.sqf
if( isServer ) // To avoid duplicates we make sure only machine executes the code, in this example the server
{
	// Instead of looping and sending the request in multiple messages we send them in 1 call, more efficient use of network resorces
	["Hello", "Evertbody"] remoteExec ["TAG_fnc_addDiarySubject"];
}

// Instead of script.sqf make it a function, avoids compiling during runtime.
// fn_addDiarySubject.sqf

if( hasInterface ) then { // Filter out dedicated server and headless clients

	params ["_subject", "_displayName", ["_picture", ""]];
	player createDiarySubject [ _subject, _displayName, _picture ];

	// You could also just pass the parameters directly in but that is less readable:
//	player createDiarySubject _this;

};

"script.sqf" remoteExec ["execVM",2];

?

No.

If script.sqf is available for players, then

"script.sqf" remoteExec ["execVM", allUnits select { isPlayer _x }];
