And work. Thanks for the good words! I am still attempting to get caught up with a new job and such. I do intend to keep track of things a bit better though going forward and maybe even update things as time allows.

I have a nano project that is currently stalled due to issues with my installation of Robocode, but looks very promising. It has three modes of movement, two of them reacting to enemy fire, and a PM gun.

The only problem is, I can't store .5 as a char, it gets rounded down to 0. So, I had to switch to 1 stored as a char and then divided by 2 to decode the value to a double. Then it was a few bytes over, so I had to switch from WeekendObsession's gun to Moebius's gun. But, in order to have any accuracy with that, I needed to add a setAdjustGunForRobotTurn(true);, which cost 5 bytes and still left me 2 bytes over. If you think you could help, I could post my code.

By the way, I recently helped Chase with his Talon project--a nano with MRM. But I have a feeling that there is a more effective way to implement wall avoidance...

Send me your version that has the best performance but is only a few bytes over, I might have an idea of how to shrink it... as well as a secret weapon which does the same ;-)

THANKS! If I can get it below 250 with the original gun, it would probably take 2nd from Sabreur, and might even give LBB a rough time (until, of course, Mike updates the tables).

Do you want me to post the code here, on a new page, or actually package the bot and host it on the repository?

Sheldor‎16:21, 19 March 2013
 

Just the code is great.

Skilgannon‎16:35, 19 March 2013
 

I didn't compile this so there may be a few minor errors. Thanks again.

I'll look at this a bit tonight. There is a savings that can be had by compiling with a different Java compiler. I remember that :)

Miked0801‎00:24, 20 March 2013

Thanks.

Skilgannon has already addressed the issue on another talk page, but I would appreciate any help I can get.

Sheldor‎03:00, 20 March 2013
 

BTW, I still feel very that LBB is a pretty cheezy bot. Abusing tables like that probably shouldn't be fair. It takes hours and hours though to get each bot optimized so maybe that makes it a little better overall. besting Moebius is a better accomplishment. At least he doesn't cheat...
