Requires Unity 2018.4/2019/2020/2021/2022 or higher (run its setup utility after installing to activate shortcuts and features based on your current Unity version). If you have an older Unity version I got you, find more info below.

IMPORTANT: if upgrading from a version older than 1.2.420, follow these instructions carefully.

DOTween is a fast, efficient, fully type-safe object-oriented animation engine, optimized for C# (it is also the evolution of HOTween, my previous Unity tween engine).

NOTE: DOTween Pro is also available, with additional shorcuts for external plugins, a Visual Path Editor, a Visual Animation Editor and a script-only low-level API to animate TextMesh Pro texts per-character (skew, scale, rotate, move).

FEATURES

Lightweight, highly optimized, performant, memory efficient
Modular (you can activate/deactivate references to major Unity systems like physics/UI/etc)
Animate anything, either with shortcuts or with DOTween's generic way
Tween strings with rich text support and scrambling options
Organize your tweens in complex groups that can be controlled as a single tween
Tons of control methods (Play, Pause, Goto, Rewind, Complete, and more)
Looping (with Yoyo and Incremental additional options), easing (including custom easing with AnimationCurves), from and relative tweens, and more
A wide array of callbacks
WaitFor(tweenEvent) methods that can be used inside coroutines
Blendable tweens
Animate objects along linear or curved paths with constant speed (or not: you choose), with various orientation options
Extra options depending on the tween type, like snapping or rotating along an object's self space
Utility Panel which allows you to set DOTween's preferences

Easy Performant Outline

NOTE: Since the Asset Store now supports only packages made with Unity 2018.4 or newer, you can find DOTween versions compatible with older Unity versions here.
