Class
MaplibreNativeFfiGestureMomentum
Description [src]
final class MaplibreNativeFfi.GestureMomentum : GObject.Object
{
/* No available fields */
}How a gesture keeps moving the camera after the user lets go.
A part moves only when its velocity is set, and each part slows on its own.
Every part defaults to MAPLIBRE_NATIVE_FFI_MOMENTUM_DECAY_MODEL_FRICTION
with a half-life of 140 ms, and these other defaults:
- Pan stops at 10 logical pixels per second, needs a release of at least 200, and counts a release faster than 10000 as 10000.
- Zoom stops at 0.01 levels per second and moves at most 2.5 levels. Its snap settles on the nearest whole level.
- Bearing stops at 1 degree per second and needs a release of at least 60. Its snap settles on north within 7 degrees.
- Pitch stops at 1 degree per second and needs a release of at least 5. Its snap settles flat within 7 degrees.
