In preparation for caching the groundnet in the NavCache, make taxi-nodes and parkings inherit from FGPositioned. As part of this, make them heap (as opposed to value) classes, disable their copy-constructors, remove many mutating operations, and give them real constructors.
* Pregenerating taxiroutes could interfere with runway assignments by ATC, when conditions changed, resulting in a taxi to one runway and a takeoff from another
* A simpler solution for the "Error in Traffic record bug". This still needs some more testing, but I haven't seen any error message anymore, since changing to the current code.
* Initialize AI traffic at speed zero, this should prevent some weirdness observed under boundary conditions.
* Don't activate groundnetwork proximity detection for pushback traffic until the "ready for startup message is transmitted. this should allow sufficient time for them to reserve a route, but a little more testing still needs to be done.
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
* Improved groundnetwork routing algorithm. Don't uncesscarily block taxiways. Instead, use a "just-in-time" blocking system. The unblocking algorithm still needs some work, but the current version is already a major improvement over the previous version.
* Some tweaks to the handover from ground to tower controller. Aircraft could refuse to take-off of even refuse to taxi onto the runway. This now seems to be solved.
* Landing AIAircraft now land properly!!!
* Fixed problems with takeoff scheduling.
* Untangled several vertical speed calculation algorithms.
* No more bent-over-backwards and jump-in-the-air AI aircraft initializations.
* Fixed intermixed target speed and target altitude during climb phase.
* Implemented beginnings of a "line up and wait" procedure.
* Tried to use actual runway elevation for calculating the decent profile.
Traffic Manager:
* Just continue routing until we run out of flights. This change removes one of the major requirements for setting the "Home port" field.
* Add a time restriction requirement for the aircraft scheduler; this became necessary after removing the limited-to-home-port routing restriction.
* Added a new field to the heuristics calculation: take into account whether an aircraft has already been used in a previous session. Rotate aircraft assignments for greater variability across sessions.
* Added a revision number to the cache files, so that old cache results, which are no longer compatible with the new file format, are discarded.
Groundnetwork and traffic control:
* Added a revision number to the cache files, so that old and incompatible results are discarded.
* The caching algorithm probably didn't store the correct data for airports that were processed while the user was quite far away. This is now corrected by checking whether the cached elevation data are equal to the generic airport elevation.
AIAircraft:
* I've been searching for the infamous aircraft bend-over-backward bug, that can occur during initialization, but to no avail yet. The only variable potentially responsible (tgt_vs) wich can explain the irregular jumping behavior, as well as the weird pitch results is initialized in AIAircraft's only constructor (through AIBase), and I can't find any situation in the ground handling code where this variable could get bizarre values. But,
* a couple of tgt_vs. calculations appear to be completely redundant. This value was calculated twice inside the ProcessFlightplan function, and subsequently again in the updateSecondaryTargetValues function. I have removed the calculations in the process flightplan function, without any apparent side effect.
- Better transistion between taxi and takeoff phases.
- Skipping the pushback stages when a gate doesn't require push-back.
- Some test code always chooses the user aircraft as the one that has to hold position.
- Change AIFlightPlan::waypoint into an independent class FGAIWaypoint
- Don't update leg count until the aircraft has passed the last waypoint that was created by the corresponding leg
- Clear ground network rendering for controllers that are no longer active.
