SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PrimeTween provides zero-allocation, high-performance tweening for Unity, enabling smooth animations without GC spikes.

Core Features & Use Cases

  • Transform tweens: position, rotation, and scale with zero allocations for performant movement.
  • UI tweens: fades, slides, and visual effects that keep frame times steady.
  • Color tweens: color transitions for sprites and UI elements with smooth interpolation.
  • Sequences: build complex animation flows with chaining and parallel groups.
  • Value tweens: numeric interpolation for gameplay variables and UI metrics.
  • Callbacks & chaining: start, update, and complete hooks with reliable sequencing.

Quick Start

Start by calling Tween.Position or Tween.Scale on a target Transform to create a simple, zero-allocation animation.

Frequently Asked Questions about tools-unity-primetween

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent GC spikes from Unity animations during gameplay?▼

Zero-allocation tweening prevents GC spikes in Unity animations by interpolating transforms, colors, and UI elements without creating memory overhead, keeping frame times steady during gameplay effects.

How do I create a sequence of chained UI animations in Unity?▼

Build complex Unity UI animation sequences by chaining parallel groups and applying callbacks, enabling reliable start, update, and complete hooks for fades and slides.

Does zero-allocation tweening support numeric value interpolation for gameplay metrics?▼

Yes, zero-allocation tweening supports numeric value interpolation, allowing you to smoothly animate gameplay variables and UI metrics without triggering garbage collection.

What is the best way to animate Transform position and scale in Unity without memory allocation?▼

The best way to animate Transforms without memory allocation is using zero-allocation tweening patterns, applying position, rotation, and scale interpolations directly to targets.

Can I smoothly transition sprite colors in Unity using zero-allocation sequences?▼

Yes, you can smoothly transition sprite and UI element colors using zero-allocation tweening, which provides color interpolation capabilities within high-performance animation sequences.

When should I use zero-allocation tweening instead of standard Unity animation?▼

Use zero-allocation tweening for high-performance Unity projects requiring smooth UI animations, gameplay effects, and complex sequences where standard animations cause frame drops or GC spikes.
