The files in the attached tarball make the following changes to FlightGear: - rename the existing FGInterface::init() method to FGInterface::_setup to get it out of the way - move *all* FDM initialization code out of src/Main/fg_init.cxx and into FGInterface::init(), and clean up fg_init.cxx a little (especially by removing the zillions of attempts to place the plane on the ground at various locations in the code) - modify FGInterface::bind() so that no values are picked up automatically at bind time (they are set previously by init() instead) - modify the init() methods of the classes derived from FGInterface (i.e. larcsim, jsbsim, balloon, magic, and ada) to invoke FGInterface::init() explicitly before doing their own setup I don't claim that the code in FGInterface::init() is optimal (or even correct), but it seems to work for on-ground starts with both LaRCSim and JSBSim on runways pointing various directions from near sea level to about 700' ASL (the range I happened to test). I expect that Jon and Tony will want to look at the code and refactor and correct it now that they can see what's going on in one place. Here's a quick outline of what is invoked: cur_fdm_state = new <whatever>(dt); cur_fdm_state->init(); cur_fdm_state->bind(); The constructor allocates memory and sets default values only (with the help of the FGInterface::_setup() method). The init() method pull any required properties out of the property tree and sets up the initial state of the FDM. The bind() method takes ownership of FDM-related properties so that the FDM can publish them to the rest of the sim. Note that bind() and init() are virtual, so any implementation in a subclass will hide the implementation in FGInterface; that's why subclass implementations of init() and bind() have to invoke FGInterface::init() and FGInterface::bind() explicitly, probably at the start, so that they get the basic initialization. |
