[HELP] Using entities and network

Fanto66 · 2022-03-07T20:12:48.859Z

Hello, I am creating a pretty simple script which needs to rotate a gate (in a ymap) 90 degrees when a button is pressed. I currently have a working mode, but only works for an individual client: the rotation is not synced.

In order to sync the entity across all systems, I have tried playing around the different Network natives such as NetworkRegisterEntityAsNetworked, NetworkGetEntityIsNetworked, ObjToNet, NetToObj, SetNetworkIdExistsOnAllMachines. Yet for some reason, the rotation does not sync.

This is my code right now. I changed some variables names for code privacy.

client:

if IsControlJustPressed(1, 38) then

            local gate = GetClosestObjectOfType(barrier.x, barrier.y, barrier.z, 750.0, GetHashKey('THE_NAME_OF_MY_PROP'), 0, 0, 0)
            --SetEntityAsMissionEntity(gate) --edited out because useless (?)
            NetworkRegisterEntityAsNetworked(gate)

            while not NetworkGetEntityIsNetworked(gate) do
                NetworkRegisterEntityAsNetworked(gate)
                Citizen.Wait(1)
            end

            local gateID = ObjToNet(gate)
            SetNetworkIdExistsOnAllMachines(gateID, true)
            TriggerServerEvent('esx_name_of_my_script:opengate', gateID, true)
            Citizen.Wait(Config.Time)
            TriggerServerEvent('esx_name_of_my_script:opengate', gateID, false)
end


RegisterNetEvent('esx_my_script_name:open')
AddEventHandler('esx_my_script_name:open', function (gateID, open)
  print('recieved open with ID' .. gateID)
  local gate = NetToObj(gateID)
  if open then
    for i=-180, -90, 1 do
      Citizen.Wait(Config.Speed)
      local rotation = int2float(i)
      SetEntityRotation(gate, 0.0, rotation, GetEntityRotation(gate, 2).z, 2, true)
    end
  else
    for i=-90, -180, -1 do
      Citizen.Wait(Config.Speed)
      local rotation = int2float(i)
      SetEntityRotation(gate, 0.0, rotation, GetEntityRotation(gate, 2).z, 2, true)
    end
  end
end)

Server:

RegisterServerEvent('esx_my_script_name:opengate')
AddEventHandler('esx_my_script_name:opengate', function(gate, open)
    print('recieved open gate with ID ' .. gate)
    TriggerClientEvent('esx_my_script_name:open', -1, gate, open)
end)

Thanks in advance to anyone who could help me understand the game of networking props and syncing movements.

Try : Client :

 GateID = NetworkGetNetworkIdFromEntity(gate) ( or ObjtoNet)
	TriggerServerEvent('esx_my_script_name:opengate', GateID , true)

Server :

RegisterServerEvent('esx_my_script_name:opengate')
AddEventHandler('esx_my_script_name:opengate', function(gate, open)

 local sid = NetworkGetEntityFromNetworkId(GateID)
        if sid and DoesEntityExist(sid) then
           TriggerClientEvent('esx_my_script_name:open', -1, sid, open)
			
			end

end)

Delete local gate = NetToObj(gateID)

I’m not sure what you wanted to do on your first line of client code, but it does not compile into FiveM. Instead, I removed the ( or ObjtoNet) part. With this modification being done, and the rest of the code being updated with what you sent me, the result.

Darek_Affinitix · 2022-03-08T16:53:37.706Z

ObjtoNet OR NetworkGetNetworkIDFromEntity do the same / use one or the other

It work or nop ?

Fanto66 · 2022-03-08T19:41:24.939Z

well then I checked with NetworkGetNetworkIDFromEntity and it doesn’t work; neither for me, nor for the other players

Darek_Affinitix · 2022-03-08T19:46:25.149Z

So , try to move your entity in server side

SetEntityRotation work client and server side

Fanto66 · 2022-03-08T19:57:53.281Z

Which would look something like this:

server:

RegisterServerEvent('esx_my_script_name:opengate')
AddEventHandler('esx_my_script_name:opengate', function(gateID, open)
    local sid = NetworkGetEntityFromNetworkId(GateID)
    if sid and DoesEntityExist(sid) then
        --TriggerClientEvent('esx_my_script_name:open', -1, sid, open)
        if open then
            for i=-180, -90, 1 do
            Citizen.Wait(Config.Speed)
            local rotation = int2float(i)
            SetEntityRotation(sid, 0.0, rotation, GetEntityRotation(sid, 2).z, 2, true)
            end
        else
            for i=-90, -180, -1 do
            Citizen.Wait(Config.Speed)
            local rotation = int2float(i)
            SetEntityRotation(sid, 0.0, rotation, GetEntityRotation(sid, 2).z, 2, true)
            end
        end
	end
end)

but doesn’t work on my side. No particular message in f8 nor server console

Zip me your script, I try to fix when I’m home

Fanto66 · 2022-03-09T19:49:50.021Z

Can you use the code I sent to build the script?

Darek_Affinitix · 2022-03-10T05:02:41.826Z

Do you create an object barrier or you want to move native barrier ?

Fanto66 · 2022-03-10T13:58:49.651Z

I want to move a native barrier which has been “spawned” thanks to a ymap

Fanto66 · 2022-03-12T19:54:34.184Z

up; does anyone have an idea, or has already done something similar that I could inspire from?

Darek_Affinitix · 2022-03-12T20:33:54.203Z

if u can , delete your barrier in ymap and try CreateObject CreateObject - Natives @ Cfx.re Docs your barrier with param “isNetwork” on true

Fanto66 · 2022-03-23T21:24:16.013Z

So I tried doing this, but I still couldn’t get it to work.
I brainstormed for a bit, and came to the conclusion that I could get the entity individually, on every client, thanks to the coordinates of the player opening the barrier:

TriggerServerEvent('esx_kriza_bridge_toll:opengate', position, true)

--Event gets sent to server, and then back to every client

RegisterNetEvent('esx_kriza_bridge_toll:open')
AddEventHandler('esx_kriza_bridge_toll:open', function (pos, open)
  local gate = GetClosestObjectOfType(pos.x, pos.y, pos.z, 750.0, GetHashKey('kriza_barrier_props'), 0, 0, 0)
  if open then
    for i=-180, -90, 1 do
      Citizen.Wait(Config.Speed)
      local rotation = int2float(i)
      SetEntityRotation(gate, 0.0, rotation, GetEntityRotation(gate, 2).z, 2, true)
    end
  else
    for i=-90, -180, -1 do
      Citizen.Wait(Config.Speed)
      local rotation = int2float(i)
      SetEntityRotation(gate, 0.0, rotation, GetEntityRotation(gate, 2).z, 2, true)
    end
  end
end)

Hope this will help anyone who has the same issue as me
