In the WB-Sim Cessna, they use animation events called:
CDI1: (L:INSTRUMENT_CDI_KNOB_COURSE_1_1, Number)
CDI2: (L:INSTRUMENT_CDI_KNOB_COURSE_2_1, Number)
HDG: (L:INSTRUMENT_HeadingIndicator_Knob_Heading_1, Number)
It makes sense that the animation should be controlled by a separate event, as the course itself can, and should be adjusted by incrementing and decrementing the events with some acceleration, independent of the movement of the knob. I increment and decrement the following data events with acceleration:
NAV OBS:1
NAV OBS:2
AUTOPILOT HEADLOCK DIR
I'm not sure if the former mentioned events that control the animation in the WB-Sim Cessna are default events, but at least these latter data events are the same I use to control the content of the knobs in the Black Square aircraft.
For knob-animation in the Black Square aircraft, it would be great if a similar approach as used by WB-Sim could be utilised in the upcoming Dukes - and in the updates of the previous aircrafts following...
