Generic Instrument Tips

This page is a place-holder for future documentation that will apply to X-Plane 920.

The rotary can be used as a single image layer, but with dynamic lighting. Set it to no click, one image.
Rotary can be used behind an image to get "dynamic lighting" onto a background. (But - don't make it too large - spot lights affect overlays UNIFORMLY. Burns VRAM. No shadows!)
Rotaries can be used with rheostats - set the rheostat to no -1 layer on top of the rotary with no click, customize hot spots. Same trick works with triggers.
Rheostats can have overlays - save VRAM.
Set rheo step 2 to 0 to get incremental movement.
Key frames must be continuous EXCEPT for rotaries - use to re-arrange enums.
Rotary key frame output < 0 means it disappears. Use for annunciators. Don't need transparent frame. Save VRAM.
Rotary key frame > digits WRAPS. USe for repeating animation like trim wheel.
Generic needles can be offset - save VRAM!
Needle can act as a heading bug, via offset and drag.
Key frame tables can be clamped by doubling an output value, e.g. (-1,0) (0,0) (1,1) (2,1)
Put a rotary (no click 1 phase) as a face plate over a pointer, but set the pointer itself to clip, to ensure that if the pointer exceeds its "masks" bounds it disappears.
