If you manage to fit that Random/Linear gun into it, will you entered it to NanoRumble (not melee)? This bot may kill the DoctorBob records!! » Nat | Talk » 14:52, 1 June 2009 (UTC)

It fits :) - I just need to find 2 more bytes to enter it into the normal rumble due to it no longer being able to call getBattleFieldWidth() and Height(). The other problem being random/linear is poor for melee - linear reduction linear is better (Infinity style.) To make it melee proof will require another 4 bytes or so. Hmmm --Miked0801 15:36, 1 June 2009 (UTC)

OMG, I found my 2 bytes. I had e.distance() cached in a register, but wasn't using it. Next release will have random linear gun with battleField sizes taken into account. Going for overall best rating next. --Miked0801 17:06, 2 June 2009 (UTC)

Congrats on the Nano crowns! =) That didn't take very long. --Voidious 15:45, 2 June 2009 (UTC)

Great work! Number one in both... very impressive, especially in a nano! --Skilgannon 16:10, 2 June 2009 (UTC)

Good job man! --zyx 20:57, 2 June 2009 (UTC)

Awesome stuff! I really should try more nano and more melée --Rednaxela 23:07, 2 June 2009 (UTC)

Wall Avoidance

I recently saw this code from DustBunny:

// Use a very simple running average system.  /2 is as cheap as I can get this
xForce = xForce *.9 - Math.sin(absoluteBearing) / distance;
yForce = yForce *.9 - Math.cos(absoluteBearing) / distance;
		
// Get our turn angle - factor in distance from each wall every time so we get
// pushed towards the center when close to the walls.  This took a long time to come up with.
setTurnRightRadians(Utils.normalRelativeAngle(Math.atan2(xForce + 1/getX() - 1/(getBattleFieldWidth() - getX()), 
					   yForce + 1/getY() - 1/(getBattleFieldHeight() - getY()))
						- getHeadingRadians()) );

I was wondering... what's up with the 1/getX() - 1/(getBattleFieldWidth()-getX()), and the same with the Y? —Preceding unsigned comment added by Abalabazn (talk • contribs)

It is a Anti-Gravity Movement system. If you want to learn about this more, I don't suggest your to learn from NanoBot, because they are obfuscated to gain as much codesize possible. --Nat Pavasant 13:06, 2 June 2010 (UTC)
