Variables Client/Server

[redditing]

The case looks like this, I have a variable (Let's call it Ammo) that IS TO be in the giveWeapon function (source, 22, Ammo, true) but the problem is that this Ammo variable has the script type "client" and the function is the server script type, so how can I make this variable in this function? If someone has not understood what is going on, there is still a code to simplify...

 

-- Client side
local Ammo = 60
local AmmoMarker = createMarker(0, 0, 1, "cylinder", 2.0)
local WeaponMarker = createMarker(0, 0, 1, "cylinder", 2.0)

addEventHandler("onClientMarkerHit", AmmoMarker, function()
    Ammo = Ammo + 1
end)
addEventHandler("onClientMarkerHit", WeaponMarker, function()
    -- Here I get a weapon, the variable "Ammo" is the number of bullets
end)

-- Server Side

--??? Problem with importing variable "Ammo"

Try to use custom events.
addEvent
addEventHandler
triggerServerEvent

Basic example: (but doesn't work very well with multiple players, since serverside is 1 environment and clientside an environment per player)

 

 triggerServerEvent ( "setAmmo", resourceRoot, Ammo)

 

addEvent("setAmmo", true)
addEventHandler("setAmmo", resourceRoot, 
function (Ammo_) 
	Ammo = Ammo_
end, false)

If you find it difficult to work with the event system, you can also try this out:

Example:

Spoiler

 Before you can use  the code below

 

The same as the example:

 

Client

callServer("setAmmo", Ammo)

 

Server

function setAmmo(Ammo_) 
	Ammo = Ammo_
end

 

---

 

Enhanced with callback:

 

Client

callServer("setAmmo", Ammo, 
function (Ammo_) 
  outputChatBox("Ammo has been set to " .. tostring(Ammo_) .. " on serverside")
end)

 

Server

function setAmmo(Ammo_) 
	Ammo = Ammo_

	return Ammo_
end

Okay, I have one problem, when I get into this "cylinder" then it gives me a pistol but with 30 bullets despite the fact that "Ammo" has a value of 72 Can you help me with that?

 

-- Client side
addEvent("WeaponGetAmmoToServer", true)

local Ammo = 72
local AmmoMarker = createMarker(0, 0, 1, "cylinder", 2.0)
local WeaponMarker = createMarker(0, 0, 1, "cylinder", 2.0)

addEventHandler("onClientMarkerHit", AmmoMarker, function()
    Ammo = Ammo + 1
end)
addEventHandler("onClientMarkerHit", WeaponMarker, function()
    addEventHandler("WeaponGetAmmoToServer", root, function()
        return Ammo
      end)
    
    triggerServerEvent("GiveWeaponToPlayer", root)
end)

-- Server Side

addEvent("GiveWeaponToPlayer", true)

addEventHandler("GiveWeaponToPlayer", root, function(prl)
    	local prl = client
    	giveWeapon(prl, 22, triggerClientEvent("WeaponGetAmmoToServer", source), true)
    end)

This script return Colt45 with 30 Ammo, but i want 72 from variable

You can't use triggerClientEvent to return values. Only MTA-Communication-Enchantment can do that with a callback, like this:

Spoiler

 

Client

function getPlayerCustomAmmo ()
	return Ammo
end

 

Server

addEvent("GiveWeaponToPlayer", true)
addEventHandler("GiveWeaponToPlayer", root, function(prl)
    	local prl = client

	callClient(prl, "getPlayerCustomAmmo", 
	function (Ammo_)   
		giveWeapon(client, 22, Ammo_, true)
	end)
    
end)

 

 

And I am not even sure that you need to do that, you can already provide that information on your first triggerServerEvent.

triggerServerEvent("GiveWeaponToPlayer", root, Ammo)

 

addEvent("GiveWeaponToPlayer", true)

addEventHandler("GiveWeaponToPlayer", root, function(Ammo_)
	local prl = client
	giveWeapon(prl, 22, Ammo_, true)
end)

So I have a question (hypothetical question) can I return the value using "callServer", "callClient"?

yes, but only to a callback function as you can see in the example.

callClient(prl, "getPlayerCustomAmmo", function (Ammo_) end )
