Corner Movement

In the early days of Robocode, one of the frustrating things about trying to excel in melee was that the bots that seemed to do the best in battle did stupid little patterns in the corners of the battlefield. This came from the general observation that the bots that lasted to be one of the last standing were the ones that got to the corners the fastest. While this isn't really always true, there are probably fewer bots near you in a corner than in the middle, so the technique works ‒ just go to the nearest corner, keep moving, and kill anything that's trying to take your corner from you. I experienced frustration with this movement when I would watch SandboxLump with his stupidly simple movement kill Coriantumr in so many of my tests. Out of my frustration came Lib, the most complex Corner Movement ever put into a NanoBot (I assume that's still true, it at least was at the time). Traditionally, using Corner Movement will make you specialized as a melee bot, because it tends to work better against the best melee bots than against mediocre ones.

Corner Movement is moving in a regular pattern in a corner of the battlefield. This strategy is often used by beginner robots and NanoBots in melee.

The Sample Bot Corners implements a primitive version of this movement. The current state-of-art corner pattern mover is Lib.
