[How-To] Create a basic script

Capal · May 4, 2017, 10:47am

@pongo1231 you can add that plz ?

List of native function is here > List of native functions

What data return a funtion, you can use > Native

for showing data from F8 you can use Citizen.Trace

now someone can tell me how can fing data from this ?

local pos = GetEntityCoords(player)

how can find x, y and y inside pos if i don’t know is exist ??? (pos.x, pos.y, pos.z)

Thank you so much Scammer!

Rouche · May 27, 2017, 10:36pm

Thank you for this awsome resource.

ThinOps · June 16, 2017, 9:40pm

what shud i be editing this on c++ or somethaing else

Xnitro67 · July 1, 2017, 9:10pm

um so how would it be if you wanted it to say Welcome ‘user’ to this server. ‘user’ would change for each person that joins?

xander1998 · July 1, 2017, 10:30pm

I believe this would work. I have not tried it though. @Xnitro67

-- SERVER --
RegisterServerEvent("welcomeMessage")
AddEventHandler("welcomeMessage", function(id)
	local name = GetPlayerName(id)
	TriggerClientEvent("chatMessage", -1, "WELCOME", {255,0,0}, name .. " to the server!")
end)

-- CLIENT --
AddEventHandler("onClientMapStart", function()
	local serverId = GetPlayerServerId(PlayerId())
	TriggerServerEvent("welcomeMessage", serverId)
end)

Xnitro67 · July 1, 2017, 10:49pm

omg thank you it works

Maxime6678 · July 6, 2017, 1:41pm

That’s better, you can use GetPlayerName with ‘source’ @Xnitro67

-- SERVER --
RegisterServerEvent("welcomeMessage")
AddEventHandler("welcomeMessage", function()
	TriggerClientEvent("chatMessage", -1, "WELCOME", {255,0,0}, GetPlayerName(source).. " to the server!")
end)

-- CLIENT --
AddEventHandler("playerSpawned", function()
	TriggerServerEvent("welcomeMessage")
end)

Could someone private message me and help me with the following, I am quite new to learning Lua, but I’ve picked it up quickly and I’m learning well.

I’ve started to learn Lua purely for GTA V use ONLY. I’ve gone to the Natives DB (http://www.dev-c.com/nativedb/) and I am unsure how I should use these natives in a working script. I am wanting to make a script that does the following, this is for learning purposes and I understand a script like this may have been done before, however I am doing it for my own benefit.

Script checks to make sure player is alive
Script checks to make sure player is not cuffed.
Script checks to make sure player is near a vehicle.
Script makes sure the target vehicle is stopped.
Script then checks to make sure target vehicle is upside down/on roof
Script then sets vehicle on ground properly.

However when I go to create this, I get confused, as I feel the natives located on that DB are for C language.

Could someone give me a basic idea of how the natives work, the syntax and how they should be structured for Lua only.

I would be eternally grateful.

https://wiki.fivem.net/wiki/Client_functions
has all information you might need.
In short, a C++ NATIVE_NAME_GOES_HERE is invoked in Lua with NativeNameGoesHere.
Also pointers ( the * thingies) in C++ are generally returned values in Lua.

example:
GET_SCREEN_RESOLUTION(int* x, int* y)
is done in Lua with:
x, y = GetScreenResolution()

TheOnlyLupo · July 25, 2017, 10:36am

I just wrote this real quick based on what you told me, this is the FIRST TIME i’ve applied Lua to GTA so please tell me where I am fucking up, if I am.

RegisterNetEvent('lupo:unflip')
AddEventHandler('lupo:unflip', function()

local playerPed = GetPlayerped(-1)
local targetVehicle = GetVehiclePedIsIn(playerPed, true)
local checkCuffs = IsPedCuffed(playerPed)
local checkHeartbeat = IsPedDead(playerPed)
local checkBrakes = IsVehicleStopped(targetVehicle)

-- Act on the information
if(checkCuffs(0)) then
  if(checkHeartbeat(0)) then
    if(checkBrakes(1)) then
          
          SetVehicleOnGroundProperly(targetVehicle)
          TriggerEvent("chatMessage", "[lupoFlipping:]", {255, 255, 0}, "The vehicle has been put on the ground properly.")
          
        else
          TriggerEvent("chatMessage", "[lupoFlipping:]", {255, 255, 0}, "You are either dead, handcuffed or the vehicle is moving, try again!")
    end
  end
end
end)

local targetVehicle = nil

mraes · July 25, 2017, 10:47am

Why are you passing parameters to checkCuffs, checkHeartbeat? Those are not functions, you defined them as variables.
For the rest I think that’s fine

TheOnlyLupo · July 25, 2017, 10:58am

if(checkCuffs(0))
Would that not call the variable above?
local checkCuffs = IsPedCuffed(playerPed)

RookieError?

mraes · July 25, 2017, 11:17am

You don’t call variables.
local checkCuffs = IsPedCuffed(playerPed) does the following:

call IsPedCuffed with argument playerPed
store the result in checkCuffs.
checkcuffs is a boolean variable, not a function.

Pretty rookie yeah.

TheOnlyLupo · July 25, 2017, 11:34am

I now understand. So this would work?


RegisterNetEvent('lupo:unflip')
AddEventHandler('lupo:unflip', function()

local playerPed = GetPlayerped(-1)
local targetVehicle = GetVehiclePedIsIn(playerPed, true)
local checkCuffs = IsPedCuffed(playerPed)
local checkHeartbeat = IsPedDead(playerPed)
local checkBrakes = IsVehicleStopped(targetVehicle)

-- Act on the information
if checkCuffs = 0 then
  if checkHeartbeat = 0 then
    if checkBrakes = 1 then
          
          SetVehicleOnGroundProperly(targetVehicle)
          TriggerEvent("chatMessage", "[lupoFlipping:]", {255, 255, 0}, "The vehicle has been put on the ground properly.")
          
        else
          TriggerEvent("chatMessage", "[lupoFlipping:]", {255, 255, 0}, "You are either dead, handcuffed or the vehicle is moving, try again!")
    end
  end
end
end)

local targetVehicle = nil

mraes · July 25, 2017, 11:42am

Boolean comparison is done with double equals sign and true/false.
checkCuffs == false for example.
For conciseness you can just omit the ==false or ==true really.

As for if it would work, why not try it yourself?

TheOnlyLupo · July 25, 2017, 11:51am

Ah I see Thank you!
I’d try, but I’m at work with no GTA access just learning whole being bored.

Leyer · July 27, 2017, 10:28am

This still works in the new FXserver update right?

HelpIHaveEbola · July 30, 2017, 2:57am

If anyone could help, how would I trigger a message by someone typing a command. Like if someone typed “/discord” it would say my discord, if that makes sense

ToastinYou · August 1, 2017, 5:43pm

This is probably quite a dumb question, but how would I go abouts with creating a client-side script, rather than a server-side script?
