/**
|
||||
** VTOLVehicleClass
|
||||
** This physics object generates the behavior of a VTOL aircraft
|
||||
**
|
||||
** Physical Behavior:
|
||||
** I think all VTOL craft can use the same behavior. The vertical thrust
|
||||
** is related to the user's setting and the position of the craft between
|
||||
** the flight-map-meshes. The orientation of the craft is controlled by
|
||||
** a controller which exerts torques to align the craft to a desired orientation
|
||||
** The x-y accelerations of the craft will be related to its orientation.
|
||||
** Turning will be an independent controller I guess...
|
||||
** In addition, "WheelP" bones should be used to provide landing gear in case
|
||||
** the orca tries to "land".
|
||||
**
|
||||
** Model animation:
|
||||
** For Orcas, I want to show the engines tilting and engine flames lengthening
|
||||
** and shortening. For Helecopters, I want to just tilt the rotor... Maybe
|
||||
** I'll just have to do each in a derived class which is custom coded for Orca
|
||||
** or Helecopter behavior...
|
||||
** - Decided to add support for all of the above behaviors to this class.
|
||||
**
|
||||
** Ideas:
|
||||
** - Rotor bones (helecopters), these always spin at a rate related to the
|
||||
** engine and tilt for turning and accelerating
|
||||
** - Thruster bones (orca engines), these rotate forward and back depending
|
||||
** on how much the user is accelerating forward.
|
||||
** - Flame bones (orca engines), these translate along their Z-axis to stretch
|
||||
** a flame 'skin'.
