im not sure how i can pass a true or false from the server to the client.

Thanks :smiley:

Use client and server events.

3

could you give me an example:D

4

When i get home i will show you. If you search up my k9 i do some of server to client.

5

Alright np great script btw
i dont understand what to look for or i wouldxD

6

Any events on the server called TriggerClientEvent is passing data on the k9.

7

ok ill look

20Characters

8 
TriggerClientEvent("K9:SearchVehicle", src, K9Config.Items)

Src is the client to target and K9Config.Items is the table im passing from the config.

9

so just change the src to whatever my var is then set like new var = that var? confused

10

Src is a players id. Change src to source and pass your true / false over my k9config.items.

11

ok so like
cause im trying to see if they have the items from the inventory so i made a event that checks it the changes has to true or false

TriggerClientEvent(ā€œesx_crafting:giveWeaponā€, source, has)

12

Do you know how to register a client event.

13

edited that part up there so like that?

14

Yeah the K9:SearchVehicle is a register net event on the client.

15

Do i need the source part to just pass the true or false?

16

So something like this?

Server.lua

RegisterServerEvent(ā€˜esx_crafting:checkā€™)
AddEventHandler(ā€˜esx_crafting:checkā€™, function()
local xPlayer = ESX.GetPlayerFromId(source)
local BarrelQuantity = xPlayer.getInventoryItem(ā€˜barrel_poochā€™).count
local FrameQuantity = xPlayer.getInventoryItem(ā€˜frameā€™).count
local StockQuantity = xPlayer.getInventoryItem(ā€˜stockā€™).count

if BarrelQuantity >= 1 and FrameQuantity >= 1 and StockQuantity >= 1 and not BarrelQuantity == nil and not FrameQuantity == nil and not StockQuantity == nil then
	has = true
	TriggerClientEvent("esx_crafting:pass", has)
else
	has = false
end

end)

Client

RegisterNetEvent(ā€˜esx_crafting:passā€™)
AddEventHandler(ā€˜esx_crafting:passā€™, function(has)
hasS = has
end)

17

TriggerClientEvent(ā€œeventā€, HAS_TO_HAVE_AN_ID, has)

18

so i do have to put source there?

19

I added source there still didnā€™t work :frowning:

ah. ok. source only exists when a server event is called from the client. You need to put your server id as where source is.
