I beg to differ Tomby it all has to do with this:
#define CanSeeRadar 1
#define CanSeeEye 2
#define CanSeeOptics 4
#define CanSeeEar 8
#define CanSeeCompass 16
#define CanSeeRadarC CanSeeRadar+CanSeeCompass
#define CanSeeAll 31
so if you scroll a bit further down you see somethin like this:
driverCanSee = CanSeeAll
gunnerCanSee = CanSeeAll
now.. you can make your own combinations
something like:
commanderCanSee = CanSeeAll;
gunnerCanSee = CanSeeOptics+CanSeeEar+CanSeeCompass;
driverCanSee = CanSeeEye+CanSeeEar+CanSeeCompass;
so only the commander has radar
