This is step "1" of probably "many" in the process of separating out the scene management code and organizing it within simgear. My strategy is to identify the code I want to move, and break it's direct flightgear dependencies. Then it will be free to move over into the simgear package. - Moved some property specific code into simgear/props/ - Split out the condition code from fgfs/src/Main/fg_props and put it in it's own source file in simgear/props/ - Created a scene subdirectory for scenery, model, and material property related code. - Moved location.[ch]xx into simgear/scene/model/ - The location and condition code had dependencies on flightgear's global state (all the globals-> stuff, the flightgear property tree, etc.) SimGear code can't depend on it so that data has to be passed as parameters to the functions/methods/constructors. - This need to pass data as function parameters had a dramatic cascading effect throughout the FlightGear code.

#include <simgear/structure/subsystem_mgr.hxx>
Flattened src/Systems/ subtree. Added src/Instrumentation/ with partial stab at a vacuum-driven attitude indicator.
2002-09-24 14:51:37 +00:00
Added a Gyro helper class to factor out some common code for managing a spinning gyro. Changed FGInstrumentMgr to inherit from FGSubsystemGroup, greatly simplifying the (already simple) class. I should probably rename this to FGInstrumentGroup or something similar, but not today. Added the gyroscopic turn indicator (part of the TC).

Roy Vegard Ovesen: Instrumentation and systems are now configureable from xml files. The two generic configurations generic-systems.xml and generic-instrumentation.xml configures the systems and instrumentation as it was hardcoded. You can override the generic configurations in a similar way as you override the autopilot configuration.

Gyro _gyro;
Add the ability for the AI to tumble in extreme attitudes, if /instrumentation/attitude-indicator/config/tumble-flag is true. The AI will take up to five minutes to reerect itself completely.
2003-04-04 03:25:02 +00:00
SGPropertyNode_ptr _tumble_flag_node;
Improved tumbling behaviour -- the AI doesn't just freeze now, but appears still to be indicating. Added a 'caged' property to the AI, for aerobatic work. Temporarily disabled tumbling due to pitch, until I can learn more about it. Publish the current amount of tumble (-1.0:1.0) under /instrumentation/attitude-indicator/tumble-norm.

First pass at trying to add back in the AI effect where it starts drifting off it's correct position once the gyro spins down below a certain threshold (such as what would happen in a vacuum failure.)
