Regarding the vision sensor model, what does ((p) 60.3 9) or ((P) 1.5 -129)
represent? My best guess is that it is an observed player that is outside of
the range of perceiving the uniform number and/or team, but I'm not exactly
sure. Also, what is the difference between the lowercase and uppercase P? The
manual describes the range of view, but it does not elaborate on the format of
the perception. By the way, I am using version 15 for the soccer server and
version 14 for the sensor format. Thanks in advance.
Uppercase P means that the player does not exist in agent's view area cone,
but exists within server::visible_distance.
