Background Information

Bot Name
NightBird
Extends
AdvancedRobot
What's special about it?
Nothing really. My first NanoBot.
How competitive is it?
Not so much. Not entered in roborumble due to the 2013 robocode repository crash.
CodeSize
NightBird 1.2 is 169 bytes without colors, I think it's one of the smallest bots around.

Strategy

How does it move?
It uses this homemade thingy... random movement that I made up.
How does it fire?
Simple linear targeting from the wiki page.
How does it dodge bullets?
I guess random movement can dodge some bullets...

Additional Information

Where did you get the name?
I thought about NightHawk, but that was taken. So I did NightBird.
May I use your code?
Yes. Its below, I don't really care about what you do, as long as you don't make a total copy. NightBird is a very simple beginner bot, and easy to understand.
What's next for your robot?
Better targeting.
Does it have any White Whales?
Acero and N are pretty annoying.
What other bots is it based on?
NightBird does not have code from any other bots(maybe accidentally, but I don't know).
