LitMotion — Zero Allocation Tween Library

To prevent GC spikes from frequent Unity UI animations, use a zero-allocation tweening library that avoids closure allocations during motion creation, keeping frame times stable during high-frequency micro-interactions.

Zero-allocation tweening in Unity is an animation technique that creates motion without generating garbage, which is needed when animating gameplay and UI elements frequently to maintain stable frame times.

Yes, a zero-allocation tween library requires Unity 2021.3+, Burst, collections, and a DOTS-oriented workflow to manage MotionHandle control, schedulers, and zero-closure binding patterns effectively.

To create a zero-allocation tween to move a Unity transform, configure the motion using a builder pattern to define start and end positions, duration, and easing curves without generating garbage collection overhead.

Migrating from DOTween to a zero-allocation tween library improves performance by eliminating garbage collection overhead from frequent animations, utilizing MotionHandle control and schedulers for deterministic motion sequences.

Yes, you can apply punch and shake effects to RectTransforms without causing garbage collection by using zero-closure binding patterns and scheduler selection within a zero-allocation tweening workflow.
