SuperWalls 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.

Thanks to Nat for cleaning up the bad coding caused by my horrible coding skills.

Movement

SuperWalls moves like Walls, but without a constant speed and it changes directions every now and then.

Targeting

SuperWalls uses two guns, a Linear Targeting gun and a Head-On Targeting gun. It keeps track of the number and of shots and hits of each gun, and uses whichever gun works better.
