SuperTrackFire

SuperTrackFire is a part of the Super Sample Bots set by CrazyBassoonist. It is intended to provide new robocoders with a new challenge after beating all of the sample robots.


Movement

SuperTrackFire uses a random oscillating movement. It's movement is quite bad, it will run into walls alot. This should be one of the easiest Super Sample Bots to beat.


Targeting

SuperTrackFire locks its gun on and then jiggles it just a little bit so that it does not always fire exactly head-on.
