Well, I understand where I went wrong and why it's not working as I expected. But now I'd like to learn a bit more about how asynchronous functions are executed in MTA and in which thread. Is this thread similar to an event loop, like in Node.js, or does it use a different model? And can you influence this thread, for example, by adding your own asynchronous functions? On an interesting note, there's a project called luvit that also uses an asynchronous model, but they've figured out how to wrap asynchronous functions in coroutines. For example, you can see this in action here: https://github.com/luvit/lit/blob/master/deps/coro-net.lua. This is something I would also like to achieve in MTA. However, for now, it seems impossible.

Works if written like this: local function callback(responseData, errorCode) coroutine.yield(responseData, errorCode) end But MTA doesn't support this notation. I don't understand why this works: local function test() return 'Hello' end local testCo = coroutine.create(test) local result, data = coroutine.resume(testCo) outputDebugString('Data: '..tostring(data)) -- 'Data: Hello' And this doesn't work... local function testFetchAndOutput() local responseData, errorCode = fetchRemoteAsync(url, opts) return responseData, errorCode end local testCo = coroutine.create(testFetchAndOutput) local result, responseData, errorCode = coroutine.resume(testCo) outputDebugString('responseData: '..tostring(responseData)) -- nil I find this very strange.

I tried to implement this logic in plain Lua(5.1), but I didn't get any results. local function fetchRemote(url, opts, callback) callback("data: Yes, it's data", 200) end local function fetchRemoteAsync(url, opts) local co = coroutine.running() local function callback(responseData, errorCode) -- print(responseData) -- data: Yes, it's data coroutine.resume(co, responseData, errorCode) end fetchRemote(url, opts, callback) return coroutine.yield() end local function testFetchAndOutput() local responseData, errorCode = fetchRemoteAsync('http://site.com/foo/bar', { method = 'POST' }) print('responseData:', responseData) -- nil return responseData, errorCode end local testCo = coroutine.create(testFetchAndOutput) print(coroutine.status(testCo)) -- suspended coroutine.resume(testCo) print(coroutine.status(testCo)) -- suspended coroutine.resume(testCo) print(coroutine.status(testCo)) -- dead

Thank you for your response. Unfortunately, the example you provided will only work synchronously for the testFetchAndOutput function. The behavior I would like to achieve: -- Create a coroutine that will execute testFetchAndOutput local co = coroutine.create( function() local responseData, errorCode = fetchRemoteAsync(url, opts) return responseData, errorCode end ) -- Execute the coroutine local coRes, responseData, errorCode = coroutine.resume(co) outputDebugString('coRes: '..tostring(coRes)) -- true outputDebugString('responseData: '..tostring(responseData)) -- '{data: foo}' outputDebugString('errorCode: '..tostring(errorCode)) -- nil I want to avoid callbacks. Your example provides some insight into working with coroutines in MTA. Is there somewhere I can read more about this? I haven't been able to find any information on this. Thanks again.

I want to achieve synchronous behavior for the fetchRemote function. However, instead, I'm getting an infinite loop with the while statement. Could it be because MTA uses different addressing? local expectedResponse = {} function fetchRemoteCallback(responseData) table.insert(expectedResponse, responseData) end function fetchRemoteAsync(url, opts) expectedResponse = {} fetchRemote(url, opts, fetchRemoteCallback) end function waitForResponse() while not expectedResponse[1] do -- Wait... end end fetchRemoteAsync('http://site.com/foo/bar', { method = 'POST', headers = ... }) waitForResponse() if expectedResponse[1] then return expectedResponse[1] end

Big Update! The library is literally rewritten. Added support for CallbackButton, Button. Added send ImageData to send image data. Also: editMessageText answerCallbackQuery keyboardInit inlineKeyboardInit inlineButton inlineKeyboardMarkup replyKeyboardMarkup The example from GitHub has been updated.

wine-6.15 works good I am grateful to you for your detailed answer and thank you for helping

I know how the function works, of course, in the end I rewrote the resource for its use. But I still find it inconvenient :F (terrible fonts are due to the launch of MTA in wine)

Since the dxCreateRenderTarget draws in the upper-left corner, this creates problems for me. If the function had the form dxCreateRenderTarget (x, y, w, h, [ ... ]), I wouldn't ask this question :_)

Hello. I'm doing something like a GUI, and I need to draw text inside a square or rectangle. I tried to implement this using dxCreateRenderTarget, but it allows you to create a render target element not in the specified coordinates, as I reported in the issue on github. Maybe there are ideas on how it could be implemented yet? Maybe there is some shader...

Well, I mean, if the server script will tell the client that some file has changed (via triggerServerEvent/triggerClientEvent). Just checking if the size of this file has changed. In this case, Clint could download it again. And if we talk about scripts,it was possible to implement LiveCode/HotReload using loadstring. But this is of course stupid

Thanks. Interestingly, it turns out that you can implement something like love code by changing the resource code on the server, it would change on the client.

Hello. The FileOpen function works for me without problems in the server script. But it does not work on the client side. meta.xml <meta> <!-- Information --> <info name="nine" author="uriid1" version="0" type="script" /> <!-- Scripts --> <script src="main.lua" type="client" /> <!-- MTA Version--> <min_mta_version server="1.5.8" /> </meta> main.lua local hFile = fileOpen("test.txt", true) -- attempt to open the file (read only) if hFile then -- check if it was successfully opened local buffer while not fileIsEOF(hFile) do -- as long as we're not at the end of the file... buffer = fileRead(hFile, 500) -- ... read the next 500 bytes... outputConsole(buffer) -- ... and output them to the console end fileClose(hFile) -- close the file once we're done with it else outputConsole("Unable to open test.txt") end test.txt it is located in the root of the resource and contains the text " Hello World!" I just realized that I didn't specify in meta.xml file test.txt. now I wonder if it is possible to somehow load a dynamically modified file

I made a small library for working with telegram bot. So far, there are few functions, but if there is interest, I will continue developing in my free time. With the help of my library, you can more effectively monitor the server and its users. GitHub -> https://github.com/uriid1/MTA-Telegram-bot Put a star if you liked it
