Having problems passing server command info to client

FiveM Resource Development & Modding Discussion

Hi there everyone!

I am trying to implement some code I found for clearing an area but I’m having a problem making it work.

The command needs to be serverside so it can be restricted but I’m just not handling passing the radius variable correctly, I think. The resource starts fine but I get scheduler errors when i try /clearall 20

Client:

RegisterNetEvent('cia:clearAll')
AddEventHandler('cia:clearAll', function(radius)
	local radius = radius
	local TRadius = radius + 0.0
	local x, y, z = table.unpack(GetEntityCoords(GetPlayerPed(-1), true))
	
	-- Props
	ClearAreaOfObjects(x, y, z, TRadius, 1)
	
	-- NPC Police
	ClearAreaOfCops(x, y, z, TRadius, 1)
	
	-- Pedestrians
	ClearAreaOfPeds(x, y, z, TRadius, 1)
	
	-- rounds/weaps
	ClearAreaOfProjectiles(x, y, z, TRadius, 1)
	
	-- Vehicles
	ClearAreaOfVehicles(x, y, z, TRadius, false, false, false, false, false)
	
end)

Server:

RegisterCommand("clearall", function(source, args, rawCommand)
	TriggerClientEvent('cia:clearAll', radius)
end, true)

Can someone tell me what I’m doing wrong?

Thanks for your time!

TriggerClientEvent requires either a -1 for all clients or a playerid.

So if I’m wanting to use the playerid then I would change it to:

	TriggerClientEvent('cia:clearAll', radius, source)

?

Switch the arguments. The id should always come first.

I’m getting an error on performing arithmatic on a nil value now.

command:

clearall 20

client:

RegisterNetEvent('cia:clearAll')
AddEventHandler('cia:clearAll', function(radius)
	local radius = radius
	local TRadius = radius + 0.0  -- Arith on nil value
	local x, y, z = table.unpack(GetEntityCoords(GetPlayerPed(-1), true))
	ClearAreaOfObjects(x, y, z, TRadius, 1)
	ClearAreaOfCops(x, y, z, TRadius, 1)
	ClearAreaOfPeds(x, y, z, TRadius, 1)
	ClearAreaOfProjectiles(x, y, z, TRadius, 1)
	ClearAreaOfVehicles(x, y, z, TRadius, false, false, false, false, false)
	TriggerEvent('chatMessage', "^1Area cleared^2")
end)

server:


RegisterCommand("clearall", function(source, args, rawCommand)
	TriggerClientEvent('cia:clearAll', source, radius)
end, true)

Error:

Error running system event handling function for resource clearitall: citizen:/scripting/lua/scheduler.lua:41: Failed to execute thread: client.lua:5: attempt to perform arithmetic on a nil value (local 'radius')

Line 5:

	local TRadius = radius + 0.0

What is radius on the server side?

RegisterCommand("clearall", function(source, args, rawCommand)
	TriggerClientEvent('cia:clearAll', source, radius)
end, true)

Because radius is nothing from the displayed code.

Hi there Faxes, thanks for the help!

I’m trying to pass it as part of the command (clearall 20 would make radius 20). How would I get it to pass that to the client as radius?

RegisterCommand("clearall", function(source, args, rawCommand)
        local radius = tonumber(args[1])
        if radius then
	     TriggerClientEvent('cia:clearAll', source, radius)
        else
             TriggerClientEvent("chatMessage", source, "Please specify a radius.")
      end
end)

You’re missing an end there.

Very nice, thanks so much!
