[HELP] attempt to call global 'callServer' (a nil value)

[robod]

What I'm doing wrong?

 

Client: 

if player == localPlayer then
			setTimer( function() callServer( 'createDropPicukup', wepons_models[ weapon ], x1, y1, z1, p_rot, slot, ammo, ammoc ) end, _dropSystem[ pickup ].time +50, 1 )
		end

 

Server:

function callServer(funcname, ...)
		local arg = { ... }
		if (arg[1]) then
			for key, value in next, arg do arg[key] = tonumber(value) or value end
		end
		loadstring("return "..funcname)()(unpack(arg))
	end
	addEvent("on_server_call", true)
	addEventHandler("on_server_call", resourceRoot, callServer)

function createDropPicukup ( id, x, y, z, rot, slot, ammo, ammoc )
	outputChatBox ( "Red #FFFFFFWhite", getRootElement(), 255, 0, 0, true )
	local object = createObject ( id, x, y, z, 87, 0, rot )
	setElementCollisionsEnabled ( object, false )
	 local marker = createMarker ( x, y, z+0.25 + math.random( 0.0500, 0.1005 ) , "corona", 1.3, color_fromSlot[ slot ].r or 255, color_fromSlot[ slot ].g or 255, color_fromSlot[ slot ].b or 255, 12.5, getRootElement() )
		setElementData( marker, 'pWeapon', { getIDFromModel( id ), ammo , ammoc } ) 
		 attachElements ( marker, object )
		 setElementParent( object, marker )
	end

You can't call server functions from client side, those are 2 separate environments, callServers is availible only on the server side, not on client.

How can I call server from client then?

I tried this https://wiki.multitheftauto.com/wiki/CallServerFunction

And there is example:

-- get the local player element
local _local = getLocalPlayer()
-- define the leaveTeam command handler function
function cmdLeaveTeam()
    -- set the player's team to nil
    callServerFunction("setPlayerTeam", _local)
end
-- add the command handler
addCommandHandler("leaveTeam", cmdLeaveTeam, false)

callserver on serverside is non sense

Like this:
Client
 

function callServerFunction(funcname, ...)
    local arg = { ... }
    if (arg[1]) then
        for key, value in next, arg do
            if (type(value) == "number") then arg[key] = tostring(value) end
        end
    end
    -- If the serverside event handler is not in the same resource, replace 'resourceRoot' with the appropriate element
    triggerServerEvent("onClientCallsServerFunction", resourceRoot , funcname, unpack(arg))
end

if player == localPlayer then
	setTimer( function() callServerFunction( 'createDropPicukup', wepons_models[ weapon ], x1, y1, z1, p_rot, slot, ammo, ammoc ) end, _dropSystem[ pickup ].time +50, 1 )
end

Server
 

allowedFunctions = { ["createDropPicukup"]=true}

function callServerFunction(funcname, ...)
    if not allowedFunctions[funcname] then
        -- Protect server from abuse
        outputServerLog( "SECURITY: " .. tostring(getPlayerName(client)) .. " tried to use function " .. tostring(funcname) )
        return
    end

    local arg = { ... }
    if (arg[1]) then
        for key, value in next, arg do arg[key] = tonumber(value) or value end
    end
    loadstring("return "..funcname)()(unpack(arg))
end
addEvent("onClientCallsServerFunction", true)
addEventHandler("onClientCallsServerFunction", resourceRoot , callServerFunction)

function createDropPicukup ( id, x, y, z, rot, slot, ammo, ammoc )
	outputChatBox ( "Red #FFFFFFWhite", getRootElement(), 255, 0, 0, true )
	local object = createObject ( id, x, y, z, 87, 0, rot )
	setElementCollisionsEnabled ( object, false )
 	local marker = createMarker ( x, y, z+0.25 + math.random( 0.0500, 0.1005 ) , "corona", 1.3, color_fromSlot[ slot ].r or 255, color_fromSlot[ slot ].g or 255, color_fromSlot[ slot ].b or 255, 12.5, getRootElement() )
	setElementData( marker, 'pWeapon', { getIDFromModel( id ), ammo , ammoc } ) 
	attachElements ( marker, object )
	setElementParent( object, marker )
end

 

 

Look that wiki source shows both source that should've been inserted into client and server side

nice it works perfectly
