AnimationImplementation Struct Reference

#include <pebble.h>

Public Attributes
AnimationSetupImplementation	setup
AnimationUpdateImplementation	update
AnimationTeardownImplementation	teardown

Detailed Description

The 3 callbacks that implement a custom animation. Only the .update callback is mandatory, .setup and .teardown are optional. See the documentation with the function pointer typedefs for more information.

Note

The .setup callback is called immediately after scheduling the animation, regardless if there is a delay set for that animation using animation_set_delay().

The diagram below illustrates the order in which callbacks can be expected to get called over the life cycle of an animation. It also illustrates where the implementation of different animation callbacks are intended to be “living”.

Called by the animation system when an animation is unscheduled, to clean up after it has run. This callback is optional and can be left NULL when not needed.
