Requires Unity 2019.4/2020/2021/2022/2023 or newer (run its setup utility after installing to activate shortcuts and features based on your current Unity version). If you have an older Unity version (down to 5.6.7) I got you, find more info near the bottom.

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).

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
