Player Ship bit 5.5 is climb/dive

[NoseyNick]

Player Ship includes...
Unknown (bit 5.5, float) "Usually 0.0, though -1.0 has been observed."

ObjPlayerShip(1019,[...],Unknown55=>0,[...]),# full
ClimbDive(-1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>-1),
ClimbDive(1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>0),
ClimbDive(1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>1),
ClimbDive(1); # from helm
ClimbDive(-1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>0),
ClimbDive(-1); # from helm
ClimbDive(-1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>-1),
ClimbDive(1); # from helm
ObjPlayerShip(1019,[...],Unknown55=>0),

As I'm sure you remember, clicking "climb" will leave you climbing (-1) until you press "dive" to stop it and return to neutral (0). Clicking "dive" will leave you diving (+1) until you click "climb" to return to neutral (0).

I've definitely seen some more "analogue" values as well though, perhaps when an analogue joystick is being used?

This... isn't the same as "Pitch" though. Hmmmm.

OK, this seems to be sorta setting a "target pitch" of 0.1921150 * Unknown55
If Helm asks the ship to climb (-1) then Unknown55 will be set to -1, and Pitch will "tend towards" -0.1921150.
If you tap "dive" you'll set Unknown55 to 0, and Pitch will "tend towards" 0 (perhaps "only" getting as close as -2.8E-44 but hey that's close).
Hit "dive" again, Unknown55 will go to 1, and Pitch will "tend towards" 0.1921150.

I think the "target pitch" varies based on the ship's maneuverability. The amount of power that Engineering directs to the Maneuver system affects how fast the ship can climb/dive.
