Sim/graphics/animation/birds/wing flap deg
From X-Plane SDK
This dataref returns the wing position of the bird currently being drawn.
The sim keeps track of each bird individually and returns a different value based on which object is being drawn. Please note that:
- The bird system is not terribly flexible - I do not recommend making serious bird add-ons.
- The sim will pick amongst several bird objects based on bird behavior and LOD.
