What's special about it?

Well, it's my first (and currently only) StopAndGo bot

Great, I want to try it. Where can I download it?

https://www.robocoderepository.com/BotDetail.jsp?id=3353

How competitive is it?

At the time of writing (well, typing) this update, for 1v1 Rumble: 413 for General, in mini 179, in micro, 109.

How does it move?

StopAndGo

How does it fire?

CircularTargeting

How does it dodge bullets?

Well, StopAndGo dodges bullets...for LT/CT that is. I'll have to shrink codesize if I'm going to add MusashiTrick...

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

1v1 only

What does it save between rounds and matches?

None.

Where did you get the name?

Well, it seems logical for a StopAndGo bot to 'evade' bullets...or at least try to

Can I use your code?

Sure, but only the code for version 1.0 was released

What's next/the history for your robot?

• Making it micro DONE 8/16/2007 (child's play - all I had to do was comment out the colors...)
• Better wall avoidance DONE 8/17/2007 (added WallSmoothing)
• Sensitivity to Inactivity timer (for fear of 'false bullets') DONE 8/18/2007 (after some MAJOR code shrinking was able to fit it...with 1 spare byte lol)
• Better energy management DONE 8/19/2007 (just removed the circular targeting - with power 3 bullets takes too long)

A rough planning...

• Near future
  • 400th place in general rumble
  • 100th place for micro rumble
• Middle future
  • MusashiTrick
  • GuessFactorTargeting
  • A way better StopAndGo
• Distant future
  • 300th place in general rumble
  • The2000Club
• Most likely impossible, but if I can
  • Making it nano
  • 1st place in micro rumble
• And always, always, trying to shrink the code!

Does it have any WhiteWhales?

In terms of % score, the worst bot against it is GrubbmGrb (only 1.2% score...) in General 1v1

What other robot(s) is it based on?

AFAIK none

Comments, questions, feedback:

Hey I'm just wondering - why would your .class file CodeSize be different than for the .jar file? They definitely "should "be the same. Maybe you're using a different compiler for the .jar? Jikes is well known for creating smaller .class files than the Sun Java, in case you didn't know. -- Voidious

• Probably because I included the source - I didn't anymore, as you can see --Starrynte
• No, including the source doesn't affect the CodeSize read by codesize.jar... The filesize sure would be different, but not the CodeSize. -- Voidious
  • Oh, I see why. I have some old Evader$EnemyShot?.class in there too. Since I don't use the EnemyShot? class anymore i suppose I can delete that. --Starrynte
    • Wait when I use robocode's 'package robot' it adds this weird 'Evader$1.class'. What are the files necessary for the jar for the rumble? Maybe I can jar it manually... -Starrynte
    • The $1.class must be an [anonymous inner class], in which case ist is a necessary file. Sorry, I couldn't find a better reference. -- Simonton
      • Yep, I deleted the custom event and changed it to just check for it in run(), and now, no anonymous inner class :D, and Evader is once again a micro --Starrynte

Hmmm, got the codesize down to 596 with colors removed, 656 with colors (I set the colors 4 times in Evader to show the stop and go), I wonder how much space a small (working) WallSmoothing would take? --Starrynte (post edited)

• The smallest codesize I've ever come up with has been variations on [PEZ's iterative version]. Couldn't tell you the size off the top of my head, but if you take a look into the source of WeeklongObsession you'll see what I've done. -- Simonton
• As I said in another thread, take a peek at Raiko's source, it has some really tiny wallSmoothing. (again its not a surfer though). --Chase-san

Hmm, when I try to extract the jarfile for Raiko (to see the source) it says it's an "invalid or corrupt jarfile"...i'm using java -jar -xvf jam.mini.Raiko_0.3.jar in the correct directory...But [PEZ's iterative version] seem's to work, so thx. (btw, if you happen to know why Raiko cannot extract, I'll take a look at that too --Starrynte

• nvm, I totally forgot about the 'Extract source of downloaded robot for editing'. --Starrynte
• They are pretty much the same thing, cept Raiko's is pretty much inline. --chase-san

Ok, version 1.2 released with WallSmoothing added, waiting for stable rankings... --Starrynte

What is "sensitivity to inactivity timer"? -- Simonton

• To avoid thinking that the inactivity timer is a 0.1 bullet from the enemy --Starrynte
