Can't Manage to Make HTTP calls for a game mod

First of all, I must say I have no prior modding or Lua background. But, I wanted to create a mod for Baldur's Gate 3 by using BG3 Script Extender, which allows people to write Lua noscripts to interact with the game state.

So, I wanted to see if I could manage to write a Lua noscript that can communicate with SteelSeries Game Engine to manipulate my keyboard's lights, to react to game state (e.g. character health bar on function keys as green light).

With the help of ChatGPT I generated a simple Lua noscript for my use case, which utilizes `socket.http` library:

local http = require("socket.http")

-- Perform the GET request
local response_body, status_code, response_headers = http.request("https://jsonplaceholder.typicode.com/todos/1")

-- Print the response
print("Status Code:", status_code)           -- Similar to `response.status`
print("Response Body:", response_body)       -- Similar to `response.text()`

local function parse_json(json_str)
    local result = {}
    for key, value in json_str:gmatch('"([^"]+)":%s*("?.-["}]?)%s*[,%}]') do
        -- Remove quotes from keys and values if present
        key = key:gsub('"', '')
        if value:match('^".*"$') then
            value = value:sub(2, -2) -- Remove quotes for strings
        elseif value == "true" then
            value = true
        elseif value == "false" then
            value = false
        elseif tonumber(value) then
            value = tonumber(value)
        end
        result[key] = value
    end
    return result
end

-- Parse the JSON response
local data = parse_json(response_body)

-- Access the parsed data
print("Title:", data.noscript)
print("Completed:", data.completed)

The [jsonplaceholder.typicode.com](http://jsonplaceholder.typicode.com) link is only there to test if I can manage to make a call and get a result. I would then replace it with my local Game Engine server URL to communicate with the peripherals.

It seemed to work fine when I ran the Lua noscript using **Lua.exe**. However, after I packaged the noscript and added it as a mod to the game, the Script Extender threw an error:

Loading bootstrap noscript: Mods/SteelSeriesLights/ScriptExtender/Lua/BootstrapServer.lua
bg3se::ExtensionStateBase::LuaLoadGameFile(): Script file could not be opened: Mods/SteelSeriesLights/ScriptExtender/Lua/socket.http
bg3se::lua::State::LoadScript(): Failed to execute noscript: [string "SteelSeriesLights/Server/lights.lua"]:4: attempt to index a nil value (local 'http')
stack traceback:
SteelSeriesLights/Server/lights.lua:4: in main chunk

builtin://Libs/FileLoader.lua:34: in function <builtin://Libs/FileLoader.lua:6>

[C++ Code]: in field 'Include'
builtin://Libs/ModLoader.lua:68: in method 'LoadBootstrap'
builtin://BuiltinLibrary.lua:26: in function <builtin://BuiltinLibrary.lua:25>

From what I can understand, it is interpreting `local http = require("socket.http")` expression as a module file that I created next to my main noscript. To get around this, I checked if I could just put the whole [socket.http code](https://github.com/lunarmodules/luasocket/blob/master/src/http.lua) within the noscript itself, but it also seems to have other dependencies.

Coming from a JavaScript background, I expected to be able to call a method like **fetch** that is built-in to the language, but so far I failed to accomplish my task.

If you could direct me toward any documentation or topic about Lua that might help me understand how to make it work, I would highly appreciate it\^\^

FiveM Lua Help

Hello,

So basically purchased a FiveM noscript for esx and went to ask the creator for help on making the reward black money or dirty money instead of cash and he basically told me to screwoff. Kind of ignorant for such a small request BUT I do need some help on this code so that I am able to have it give players black money instead of clean money. Thanks in advance and for your time.

The code is as follows:

RegisterServerEvent('sh-boomerphone:sellItem', function(itemName, count, price)

local src = source

if framework == 'esx' then

local xPlayer = ESX.GetPlayerFromId(src);

if not xPlayer then return false end

if xPlayer.getInventoryItem(itemName)?.count >= count then

xPlayer.removeInventoryItem(itemName, count)

xPlayer.addMoney(price * count)

end

Key swapping Lua Scripts for 9 keys (PRTSC - PGDN)

Key swapping Lua Scripts for 9 keys (PRTSC - PGDN) to be NumPad keys (1 - 9) instead.

don't think I ever use these keys unless for something very specific but it can change back with another profile.

Is there anyone who can write this seeing as I have no clue to write noscripts at all. Thanks in advance.

Is there a way to use a function this way?

My case is very specific:

The api i use doesnt have a native checkbox, slider etc(gui) so i made one on my own, i ran out of locals to use

Checkbox("Name", "Something", x, y)

Is there any way to something like

if Controls"Something" then
otherlua.function
end


Seeing as my noscript on the other lua runs all the time? Is there any way to like call the entire noscript?

Learn Lua with EdgeTX api environment

Hi, I want to practice Lua writing EdgeTX noscripts for FPV drone telemetry. I have found a pretty decent documentation for edge tx and Lua . In order to acomplish my task I need to establish a communication with flight controller on my drone wich has betaflight firmware (see MSP communication) . There is a nice lua noscript for communication with betaflight (see here) but for me it is hard to understand how it comminicates with betaflight on byte level. Do you have any small easy to understand examples to dive into it ? Thank you

Is there a good way of generating 2D graphics without a game engine?

I want to create something like desmos but only for simple functions (ax\^2 + bx + c). I have created the function that finds the y values for many given x values so the function can be drawn. This is where I have encountered a problem, I don’t know how to generate such graphics. I have tried searching for something but all I found was game engine tutorials that incorporate Lua and not methods of displaying graphics without an engine, as for my application, I find it unnecessary.

Getting error info from custom error handler and xpcall

I’m using xpcall and want to know how to get error info from a custom error handler function.

Function error_handler()
Print(debug.traceback)
End

If I use

err, ok = xpcall(func, error_handler)

I lose the error message itself but I get the trace.

If I use

err, ok = xpcall(func, debug.traceback)

I get the error message and the trace when I print err.
