Display: Altimeter/Altitude meter, Odometer, Pitch, Facing, Speed, Coordinates and other navigation information

WoW dynamic is such that conventional aircraft instruments can bring total chaos to the display.
Therefore, this add-on must display useful, non-intrusive information or bring some fun.

Altimeter (altitude meter)

• Display current Altitude relative to the take-off point

• reset on landing (not flying)
• reset on diving out of water (not swimming)

note:

• due to quantization there is a small margin of error, but information can still be relevant/valuable

Odometer

• Display traveled ground distance - reset on mount and dismount
• Display traveled ground distance - reset from configuration menu

Coordinates

• Display current player location in x,y coordinates

Facing

• Display player Facing in degrees (0-360°) where 0° is facing North.

• Display player Facing in short-hand terminology
  (N - North, NE - North-East, E - East, SE - South-East, S - South, SW - South-West, W - West, NW - North-West)

define:

• facing: have the face or front pointing in a specified direction.
• course: the route or direction followed by a ship, aircraft, road, or river.
• direction: a course along which someone or something moves.
• bearing: the direction or position of something, or the direction of movement, relative to a fixed point.
• heading: a direction or bearing.

notes:

• mind the difference between Facing and Course
• player can face North but strife left or right - therefore Course will be West or East respectfully
• player can face North but walk backward - thus Course will be South

Course

• Dynamically show Course when it is not equal to the Facing.

Pitch

• Display Pitch when flying or swimming (or falling?) (where 0° is parallel to the ground)

• http://en.wikipedia.org/wiki/Flight_dynamics_(fixed-wing_aircraft)

notes:

• problem if player holds SPACE while flying or swimming (solved)
• if player is falling, (example) pitch can be 0° but flight path angle can be -90°
• falling still not solved

Flight Path Angle - FPA

• Dynamically show Flight Path Angle - FPA when it is not equal to the Pitch.

Thrust

• Visualize player horizontal-ground thrust
• Visualize player vertical thrust

note:

• mind the difference between actual speed and thrust
• player can try to move forward into a wall, at this moment she:
  • has zero speed, not moving but pressing against the wall
  • has for example walk thrust, if the wall is removed - this thrust will become 4.5 y/s speed

Gunpoint Animation

• Display gunpoint whose size/opening/spread depends on horizontal thrust

Speed (optional, may not be implemented)

• Display or visualize actual horizontal-ground speed
• Display or visualize actual vertical speed

Player State Icon (optional, may not be implemented)

display player state icon:

• shapeshift
  • druid shape (fly, moonkin, cat, bear and swim form)
  • shaman wolf form
• stealth form (druid, rogue)
• idle (short, long)
• non-mounted
• movement (back-pedal, walk, run)
• fall (small-jump, big-jump, fall, big-fall)
• mounted
• on taxi
• swimming
• player (dead, in control)
