LitMotion

Lightning-fast and Zero Allocation Tween Library for Unity.

Overview

LitMotion is a high-performance tweening library for Unity. It encompasses a rich set of features to animate components like Transform, along with custom fields and properties, allowing for easy creation of animations.

Following my creation of Magic Tween, LitMotion stands as my second tweening library. Leveraging the experience gained from implementing Magic Tween, LitMotion has been designed prioritizing essential features while ensuring it operates at the highest speed possible. It outperforms other tweening libraries by a staggering 2 to 20 times in various situations such as tween creation and execution. Naturally, there are no allocations during tween creation.
