revan114 Posted February 17, 2015 Share Posted February 17, 2015 I want to make a Chat Bot for Jedi Knight Academy. Basically the bot reads the chat of the server, then if a user types in chat a '!', followed by a command, the bot responds accordingly. For example if a user was to type '!Weather', the bot would respond in chat by printing out the weather. The problem is I have no real idea on how to approach this. I've never done something like this before, but it sounds like a fun thing to try to do. I've only been programming for about 9 months so I'm not sure if this project is out of my bounds or not. Any advice? I know such bots have been made in the past I can't find any information on them. The closest I could get was finding this: http://jediknight3.filefront.com/file/JK3_Chat_Scan;23795 I'd like to do this in C# if possible. Link likes this Link to comment
mrwonko Posted February 17, 2015 Share Posted February 17, 2015 You can either look through the code to find out about the communication protocol or capture the packets sent when you join a server as a spectator and chat. In general you'll mostly need to send and receive UDP packets, googling for "Quake 3 network protocol" yields some potentially useful results. Link to comment

Is that how tools like Ultra Utility do it?Basically there are two methods I am thinking of, 1: Have a bot actually join the server as a client, then join spectator and wait for commands.2: Skip the bot and just make the client(me in this case) respond to the commands automatically. Not really a bot per say, just parsing input and responding. Either way would do fine for me. I'll start looking around at the Quake 3 network protocol. Link to comment
Raz0r Posted February 17, 2015 Share Posted February 17, 2015 It can be done in the JA++ client with Lua, or by modifying the source code if you're more familiar with C. Link to comment
Futuza Posted February 17, 2015 Share Posted February 17, 2015 You should make it plugin to cleverbot.com so it can be snarky. Link to comment

revan114 Posted February 17, 2015 Author Share Posted February 17, 2015 So while I'm here, is there some sort of documentation I can read on LUA plugins in JA++? Link to comment
Raz0r Posted February 17, 2015 Share Posted February 17, 2015 You can look at existing plugins here or the source code here. There used to be some basic documentation but most of it is irrelevant now or missing. Link to comment

Raz0r Posted February 17, 2015 Share Posted February 17, 2015 It's a battle of time / effort =[ Link to comment
revan114 Posted February 17, 2015 Author Share Posted February 17, 2015 Alright so I managed to get it working. Now it responds whenever someone types in the chat !test. But the problem now is that only other people can do it. If I do it, the message doesn't show up because it tries to send it IMMEDIATELY AFTER I send !test. Antispam blocks it. Been trying for the past hour to find a way to pause the script after it receives the trigger, but to no avail. I do have a way to pause it, but it pauses the ENTIRE CLIENT each time someone uses the bot. Any advice? Link to comment
Raz0r Posted February 18, 2015 Share Posted February 18, 2015 Store the last-message-recieved-time in a global variable. Every frame (i.e. JPLUA_EVENT_FRAME or whatever it is) check if the current time is ~2s after the last received time (and the last received time is not 0), and if so, send the message then set the last received time to 0 so it won't keep trying to resend.

So that sounds easy enough, but I'm not exactly sure about how to do this: Store the last-message-recieved-time in a global variable. How do I find the last message received time? Link to comment
