Hey, I’m trying to build a simple IRC bot withing the software GameMaker Studio, my eventual plan is to create a game around Twitch chat interactions.
However, I’m having problems either connecting or receiving data. The problem I’m having is that after sending PASS, NICK, and JOIN messages I’m not receiving any data back, no messages about failing to connect or anything like that.
I’ll post my code below, the language GameMaker uses is very simple so if you have any programming experience it should be relatively simple to understand, I’ve also commented it as well.
Create Event (ran once on game start)
//Create a TCP socket
irc_socket = network_create_socket(network_socket_tcp);
//Connects to a server using a previously created socket
irc = network_connect_raw(irc_socket, "irc.twitch.tv", 6667);
//If the connection returns < 0 then it did not successfully connect
if (irc < 0)
{
trace("connection failed");
}
else
{
trace("connection successful");
}
//Creates a buffer that can dynamically change size when needed
//Set the write position to the start of the buffer
//Write the following string into the buffer
//Send a raw packet to a socket with a buffer and buffer size (non raw connections use an extra 8 byte header for some custom GameMaker thing)
//Destroy the buffer afterwards
var buff = buffer_create(1024, buffer_grow, 1);
buffer_seek(buff, buffer_seek_start, 0);
buffer_write(buff, buffer_string, "PASS oauth:shhhh...it's a secret\r\n");
network_send_raw(irc_socket, buff, buffer_get_size(buff));
buffer_delete(buff);
var buff = buffer_create(1024, buffer_grow, 1);
buffer_seek(buff, buffer_seek_start, 0);
buffer_write(buff, buffer_string, "NICK aidanstwitchbot\r\n");
network_send_raw(irc_socket, buff, buffer_get_size(buff));
buffer_delete(buff);
var buff = buffer_create(1024, buffer_grow, 1);
buffer_seek(buff, buffer_seek_start, 0);
buffer_write(buff, buffer_string, "JOIN #aidan63\r\n");
network_send_raw(irc_socket, buff, buffer_get_size(buff));
buffer_delete(buff);
Network Async Event (Code in this event is triggered when GameMaker detects incoming data)
trace("triggered");
var data = ds_map_find_value(async_load, "buffer");
var str = buffer_read(data, buffer_string);
trace(str);
irc returns a value greater than 0 indicating a successful connection since “connection successful” appears in the debug dialog however, the network async event is never triggered meaning no data is ever received.
If I change the connecting URL to another IRC network like “irc.slashnet.org” and add a USER message then I can connect to it and receive data back. From my understanding Twitch IRC doesn’t need a USER message. (adding one idn’t change anything anyway)
I’m also pretty sure the credentials are all entered correctly as I was able to make an equivalent IRC bot in Python and it successfully connected and received data back. One solution would be to create the bot in Python and save all relevant data to a file so GameMaker can read it, but I would like to do it all in GameMaker if possible.
I’ve asked in a few GameMaker communities and there doesn’t seem to be anything wrong with the code, they suggested it might be something on Twitch’s end, so now I’m here to ask you guys!
Any help would be greatly appreciated, cheers.
