Issues when running on dedicated server

[wooden jewel]

Started a thread rather than just spamming #arma3_scripting.

I decided to write my own custom jetpack system (because sci-fi), and it runs pretty much exactly how I want in singleplayer and when I start a LAN server for some basic multiplayer testing. However, when testing out on a dedicated server, some of the visuals break.

The visual stuff is relatively basic, just creating some particle / light sources, attaching them to the player, and storing the object in an array on the player.

I omitted most of the stuff that isn't necessary, considering that the entire thing is ~1,000 lines in total and most isn't relevant to the effects.

I'd greatly appreciate any kind of help people can give.

This is the entry point for my jetpack system, it runs a few checks (player not in water, player has fuel, etc.

// fn_Jetpack.sqf
// Called when pressing the corresponding keybind, starts the jetpack sequence if it does not already exist

// ...

private _jetpack = backpack ace_player;
private _jetStrength = GET_NUMBER(configFile >> "CfgVehicles" >> _jetpack >> "BNA_KC_Jet_strength", 1);

if (isNil "BNA_KC_Jet_JetpackHandle") then
{   
    // Speed and position, used for an initial boost
    private _velocity = velocity ace_player;
    private _position = getPosASL ace_player;

    // Give slight boost to start jetpacking, but only if starting from the ground
    if (ace_player call BNAKC_fnc_CanUseJetpack and isTouchingGround ace_player) then
    {
        // teleport up, increase velocity
    };

    // Event signalling a unit is starting a jetpack, EH handles visual particle effects
    ["BNA_KC_Jet_JetpackFired", [ace_player]] call CBA_fnc_GlobalEvent;

    BNA_KC_Jet_JetpackHandle =
    [
        BNAKC_fnc_JetpackFrameHandler
    ] call CBA_fnc_AddPerFrameHandler;
}

// fn_JetpackFrameHandler.sqf
// Handles the mid-air movement and removes the frame handlers when no longer flying.

// ...
private _thisHandler = _this select 1;
// ...

if (!(ace_player call BNAKC_fnc_CanUseJetpack) or isTouchingGround ace_player) exitWith
{
    [_thisHandler] call CBA_fnc_removePerFrameHandler;
    BNA_KC_Jet_JetpackHandle = nil; // Set to nil, just removing the handler keeps the global variable's value

    [BNA_KC_Jet_JetpackFuelHandle] call CBA_fnc_removePerFrameHandler;
    BNA_KC_Jet_JetpackFuelHandle = nil;
    
    //! Issue starts here, effects are not removed from player when landing on the ground

    // Wait a bit before removing effects, makes it look nicer
    [
        {
            // Delete effects
            {
                deleteVehicle _x;
            } forEach (ace_player getVariable ["BNA_KC_Jet_effectSources", []]);
            [BNA_KC_Jet_JetpackSoundHandle] call CBA_fnc_removePerFrameHandler;
            BNA_KC_Jet_JetpackSoundHandle = nil;
        },
        [],
        0.3
    ] call CBA_fnc_waitAndExecute;
};

// fn_JetpackEffectHandler.sqf
// Creates effects, attaches them to the unit jetpacking, and stores them for later deletion
// CBA XEH for "BNA_KC_Jet_JetpackFired"

//! As I type this I have a feeling this might be the problem line, but I don't necessarily see why?
if !(hasInterface) exitwith {}; // Function only contains visual effects, no need to execute on the server
params ["_unit"];

if (!(_unit call BNAKC_fnc_CanUseJetpack) or isTouchingGround _unit) exitWith {};

// Model points to spawn effects from
private _effectPoints = GET_ARRAY(configFile >> "CfgVehicles" >> _jetpack >> "BNA_KC_Jet_effectPoints", []);

{
    // Create effect, attach to player with offset using the model point
    // pushBack to array for later removal
} forEach _effectPoints;

// Save for later removal upon landing by the jetpack handler
_unit setVariable ["BNA_KC_Jet_effectSources", _effectSources];

is the players BNA_KC_Jet_effectSources being populated in dedi

None of the effects code is handled on the dedicated side because of if !(hasInterface) exitwith {};

Oh that's probably why

The code to delete the effects run on the server, but they're only created on the client's end, duh

That's probably what's causing the issue

So I either need to run the deletion code for each client, or just create the effects on the dedicated side as well.

Easier to just remove the if !(hasInterface) exitwith {}; line, but I don't see a reason for the server to have to handle the effects, so I'll remoteExec to save the objects on the server

Just something like this should work

// _unit setVariable ["BNA_KC_Jet_effectSources", _effectSources]; // Original
[_unit, ["BNA_KC_Jet_effectSources", _effectSources]] remoteExec ["setVariable"];

create effects on the client

minimises network traffic

[wooden jewel]

They are only created on the client, I use createVehicleLocal to create all of the effects

[gloomy delta]

would use a cba event instead of remoteexec but i hate remoteexec so 🤷

[wooden jewel]

Could do that yeah, but it seems a little odd to put a CBA event in a CBA event handler

Not the strangest, but still odd

[gloomy delta]

oh is it in a cba eh

just have

if (hasInterface) then {/*delete particools*/};``` no?

[wooden jewel]

// fn_Jetpack.sqf
// Event signalling a unit is starting a jetpack, EH handles visual particle effects
["BNA_KC_Jet_JetpackFired", [ace_player]] call CBA_fnc_GlobalEvent;

Then JetpackEffectHandler listens for that event
