jump detail::event::jump_t jump {} inlineconstexpr Event triggered after each jump() call. Use this event to react when the tween jumps to a specific keyframe by index. This is particularly useful for multi-point animations where keyframes represent distinct animation phases. Common use cases: Transitioning between animation states Triggering phase-specific logic Resetting to specific animation checkpoints Implementing state machines auto tween = tweeny::from(0).to(50).during(30U).to(100).during(30U).build(); tween.on(tweeny::event::jump, [](auto& t) { printf("Jumped to keyframe\n"); return tweeny::event::response::ok; }); tween.jump(1); // Jump to keyframe 1, triggers callback See also keyframeEnter For detecting keyframe transitions during playback seek For arbitrary frame jumps
