4v4 DuelBot

BDwinsAlt · January 6, 2010

I have written a bot with chatnet protocol that conforms to the rules. For the most part. The only thing is at the end of a 4v4 round, it sends stats.

Let me explain what the bot does before you consider this. Unix asks me to right a good 4v4 bot. I don't know how the existing one works, but this one seems to work fine. I have tested it extensively and can't seem to find any bugs, but it may need some new features.

This is how I have it setup


// Stafflist is in config file, so players can't use this unless in the config file.
Staff CMD: !go (arena), !shutdown

Player CMD: !about, !help, !version.... (Obvious functions)
Player CMD: !rules, !time, !begin

Rules: Displays dueling rules.

Time:  Displays time remaining, (In case bot is not granted ?timer powers)

Begin: Begins a round.  If someone begins a round an no one is playing, typing !being will restart
Begin: If a game is going, then type !begin will display that a game is currently in session.

Those are the function, these are the commands used by the bot for better gameplay, but are not required

?timer   - For conventional ?time
?lock    - To keep from having ship changes, or someone jumping in the middle of the duel
?unlock  - No game in session, have fun.
?setship - Puts the player in spec so that they can't interfere with the duel

This bot is made so no staff member has to be present to start it. Despite the name 4v4, any team size is allowed at this time. I think team-sizes should be configured in the arena configuration anyway, but if need be I'll add it to the bot config file. There is currently no team-captain, but in a real 4v4, a staff member would probably need to put someone on a freq anyway. This bot can be used during practice or whatever.

I have taken all the hard work off of your hands if you will allow me to run the bot in an arena.

It has a few simple (not a security risk) commands that it would need to allow for OPTIMAL game play.

This powers would be limited to one arena if the staff.conf file. It wouldn't really matter who hosted this bot since it poses no security risk, has nothing to do with money or anything else.

I am asking that you consider allowing me to host a bot that is productive to the zone and makes things a little more automated. I will release full source upon request of staff. My ways of doing things might be different, but I did it in the most effective way I knew possible.

Small changes would need to be made to the following files...

Example: (conf/groupdef.dir/hsfour)

; conf/groups/hsfour

; what groups can this group control
higher_than_default

; Don't shutup when displaying chats
unlimitedchat

; prefix chars
prefix_+

; commands
cmd_lock
cmd_unlock
cmd_timer
privcmd_setship

Add this to File: (conf/groupdef.conf)

[hsfour]
#include groupdef.dir/default
#include groupdef.dir/hsfour

Then just add in (conf/staff.conf)

(arena name)
UB-DuelBot = hsfour

That's all you have to do. Now, the bot gets silenced when it displays stats if not granted unlimited chat, so making it have its own group is good anyway. Those few commands won't hurt anybody with arena-restriction.

This would be a good addition to hyperspace, wouldn't take much bandwidth (not really a big deal anyway), and uses little resources. I will add any additional features/modifications necessary and do it in a timely manner.

Thank you,

BD

You should post the source.

You should post the source.

I did a few last minute adjustments, added some comment in stuff.

I did use input[x] a few times without renaming it to something like, newfreq or something, because I would have to split strings in everycase and rename it, and if you know the protocol you know what it is anyway. I can change that if need be. I'm still learning as I go, so if you see major issues, PLEASE, point them out. I need to know for future reference. Everything I know is what I taught myself and examples I have studied. I really need constructive criticism from more experienced (sometimes lazy ) people. Oh yeah, ignore the debug stuff you'll probably notice commented out.

Here's my current compilation of the bot.

Interesting approach. Some notes:

- For a simple bot like this, this design is probably okay. But, I'd imagine it'll get real messy in a hurry once you start adding other features. Perhaps consider a more OOP design in the future?

- I wasn't aware of the Properties class and that it could be used for some simple configuration. Neat.

- As of 1.5, Java supports printf style formatting via PrintStream.printf(...) and String.format(...) methods as well as the Formatter class. You may want to check that out.

- What happens when a player dies less than five times, lags out, quits or otherwise doesn't finish? Also, can they be subbed?

- Speaking of things you should check out, are you aware of jcnlib? It implements the entire chatnet protocol for you, as well as provides some utilities. If you're going to use Java for a chatnet bot, this may save you some time. Also, the 4v4 bot I made is written around it, which you can check out here.

Thanks for the tips. I didn't realize you had already made a 4v4 bot. I thought it was a mervbot plugin or something. I'll take all that into consideration. I haven't added a sub or anything yet, that's a feature I may need to add. I had a bot a lot like this in TWCore a while back used for squad duels. I can't believe you've never run across my form of loading properties. It's makes things über easy. I do think I should have broken it up a little. It's all in one thread and I usually like to break things apart more and stop using functions over and over. It is functional, so making those modifications would help. It's a stand-alone bot, so it may or may not be too important to use an already existing library, it might be easier. I'll have to check it out.

Thanks for the tips.

Question: Have you taken any programming classes? If so, what do you recommend because I plan on pursuing a career in some type of computer-related job.

Edit: I tried to download your 4v4 bot but I can't extract it. Not really sure why. I'll try again after I get some sleep.

Thanks again.

Neat indeed.
