I'm playing with a new (for me) radar right now and i think it is worth to share it.

It's a radar mostly usefull for melee bots and it scans all bots forth and back. If the radar founds all enemys in under 180 deg, the radar will change direction and search new. If only one enemy is left the radar goes to endless lock the enemy.
