Talk:BasicGFSurfer

From old wiki

This bot is stronger than expected. -- GrubbmGait

Yeah, it's stronger than my Squirrel, which was SUPPOSED to take that code and improve it but all it did was make it worse :(. --Bayen

I don't think the tutorials are under the RWPCL, I fiugured the code was just to use and abuse for anything thats sports your fancy. (not that my bots aren't under the RWPCL anyway) -- Chase-san

PEZ put GFTargetingBot under the RWPCL, but I consider the WaveSurfing/Tutorial to be available to use however you want. -- Voidious

I lifted the RWPCL licensing now. The code is in the public domain. Of course I do believe very hard in OpenSource and would encourage anyone to use it anyway. -- PEZ

I put Squirrel's code in the jar, so that makes it open source, right? Anyway, I don't think anyone would really want to use my code, for two reasons. It's extremely messy, and Squirrel isn't that good. Oh well --Bayen

• Yes, that makes it open source ;) -- Voidious

Hmm, when i run Plains against BasicGFSurfer, i sometimes get a

I can see why - it has MAX_DISTANCE set to 900, but technically the maximum distance should be 1000 - BOT_WIDTH (because it measures from center of the bot) on an 800x600 field (like a 3/4/5 right triangle). If you are as far away as possible, it will be a higher index than the stat buffer is initialized with. Really, the safest thing to do would be to calculate MAX_DISTANCE based on battlefield width and height. Hopefully, that stoppage thing is also related. I'll update the GFTargetingBot tutorial; somebody should release a BasicSurfer 1.1 =) -- Voidious

• Maybe the introduction should be changed to read, "... the basic, buggy implementation of a WaveSurfer with GuessFactorTargeting ...". =P -- AaronR

Bugfixed version 1.01 available. Made a more robust fix than just increasing the distance, without any effect on distances < 900. MAX_DISTANCE remains 900.

int distanceIndex = Math.min(DISTANCE_INDEXES-1, (int)(distance / (MAX_DISTANCE / DISTANCE_INDEXES)));
