## What it is
PrimeTween is a high-performance, allocation-free tweening library for Unity that lets developers animate transforms, values, and materials with one line of code. It supports delays, cycles, sequences, coroutines, async/await, and Inspector-based tweaking of animation properties.

## Use cases
- animate UI elements and transforms in Unity with one line of code
- create camera shake and screen shake effects
- build complex animation sequences without runtime allocations
- replace DOTween for better performance in Unity games
- add delays and timers to gameplay code
- tween material properties and custom values
- integrate animations with async/await or coroutines

## When to choose
- you are building a Unity game and need zero-allocation animations for performance-critical platforms like mobile
- you want a simple one-line API for tweens, shakes, delays, and sequences
- you are migrating from DOTween and want a faster alternative with an adapter
- you need Inspector integration to tweak animations without code changes

## When to avoid
- you are not using Unity as your game engine
- you need a general-purpose animation system for non-game applications
- you require features only available in the paid PRO version, such as no-code animation components

## Facets
- artifact type: library
- maturity: stable
- function: animation, graphics, game-engine
- domain: graphics, cross-platform
- platform: game-engine, cross-platform
- tags: unity, tweening, easing, camera-shake, screen-shake, allocation-free, sequences, game-feel, dotween-alternative, game-development
