What's so special about it?

It's my first robot which implements a small, but effective (against small bots) Random Movement. Most lightweight pattern matchers have a very difficult time hitting it. It also has multi-mode movement that runs random movement for two rounds, and then stop & go for 2 rounds and determines which performed better. It then uses the better-performing movement for the remainder of the time.

How competitive is it?

Fairly - it's #40 in the microrumble and #242 in the general rumble. It has won 85% of battles in microrumble.

Where can I get it?

Just click the download link to the right.

Version Information:

1.0 - Pattern Matching, Random Movement, Infinity lock

1.1 - stronger movement algorithm, strengthened wall avoidance

1.2 - strengthened movement even more, changed gun a wee bit ;), corrected small glitch

1.3 - small gun tweaking, better wall avoidance, stronger movement, narrow lock radar

1.4 - multi-mode movement, fixed "sticky-wall glitch" by reverting to previous wall avoidance

1.5 - a few fixes and most importantly added some antiram, improved gun/slimmed code a little

1.6 - a LOT of bug fixes, fixed antiram, improved movement, removed unneccessary snippets of code

Strategy

How does it move?

Random Movement, Stop & Go

How does it fire?

Pattern Matching

How does it dodge bullets?

Random Movement, Stop & Go

How does the melee strategy differ from One-on-one strategy?

It doesn't do melee (yet).

What does it save between rounds and matches?

A few static variables including symbolic state, effectiveness of movement methods, movement to use, and a couple others because they use less codesize :p.

Additional Information

Where did you get the name?

It just came to me :P

Can I use your code?

Absolutely. It's RWLPCL. I commented the code a lot to make it easier to understand, but it's slightly compressed to save codesize so you might have to pay semi-close attention. You can view the code by clicking the source link to the right. You can see more free code / tutorials at my code snippets page.

What's next for your robot?

wall smoothing for sure, possibly a new gun, fixes against some bots, some tweaks so it can do good in melee (V 1.8 will prob be melee)

Does it have any White Whales?

Thorn, Raiko, and any other bots that use GuessFactor Targeting, uCatcher (will be fixed in next version), Acero (yeah - that head on bot, still working for a fix for it :/)

What other robot(s) is it based on?

I used a slightly altered version of Robar's BlackWidow gun.
