keyframeLeave detail::event::keyframeLeave_t keyframeLeave {} inlineconstexpr Event triggered when leaving a keyframe segment. Fires when the tween transitions out of a keyframe section during playback. The callback receives both the tween reference and a keyframeLeave struct containing the keyframe index being exited. Common use cases: Cleaning up phase-specific resources Stopping phase-specific effects Logging animation progression Implementing phase exit handlers Coordinating complex multi-segment animations Note Keyframe indices are 0-based. Leaving keyframe 0 means transitioning from the first to the second segment. auto tween = tweeny::from(0) .to(50).during(30U) .to(100).during(30U) .build(); tween.on(tweeny::event::keyframeLeave, [](auto& t, tweeny::event::keyframeLeave evt) { printf("Leaving keyframe %zu\n", evt.key_frame); return tweeny::event::response::ok; }); tween.step(31); // Triggers: "Leaving keyframe 0" See also keyframeEnter For detecting when entering a keyframe keyframeLeave For the event data struct
