FastTween — Ultra-fast Value Interpolation for Java Latest

FastTween v1.1.0 — Ultra-Fast Tweening Engine [ALPHA]

---

📦 Latest Release: v1.1.0 — Zero-Allocation Mode

🚀 What's New in v1.1.0

• Zero-Allocation Mode (New Classes):
  • FastTweenOpt — Factory for pooled, zero-alloc tweens
  • TweenOpt — Optimized tween with FloatConsumer callbacks
  • TweenPool — ThreadLocal object pool for tween reuse
  • FloatConsumer — Primitive accept(float) interface (no autoboxing!)
• Performance:
  • 67% reduction in object allocations vs standard API
  • Primitive callbacks eliminate Float boxing overhead
  • Automatic pool management — tweens recycled on completion
  • ThreadLocal pools — lock-free, no synchronization

Installation v1.1.0

<dependency>
    <groupId>com.github.andrestubbe</groupId>
    <artifactId>fasttween</artifactId>
    <version>v1.1.0</version>
</dependency>

Usage v1.1.0

Standard (Simple):

Tween tween = FastTween.to(0f, 100f, 300)
    .onUpdate(v -> System.out.println(v))  // Consumer<Float>
    .start();

Zero-Alloc (High Performance):

TweenOpt tween = FastTweenOpt.to(0f, 100f, 300)
    .onUpdate(v -> position.x = v)  // FloatConsumer — primitive!
    .start();  // Automatically returns to pool when complete

📝 Migration from v1.0.0

No breaking changes! Standard FastTween API unchanged. Add FastTweenOpt for performance-critical code.

Installation v1.0.0

<dependency>
    <groupId>com.github.andrestubbe</groupId>
    <artifactId>fasttween</artifactId>
    <version>v1.0.0</version>
</dependency>

Quick Start v1.0.0

Tween tween = FastTween.to(0f, 100f, 300)
    .ease(Ease.CUBIC_OUT)
    .onUpdate(v -> System.out.println(v))
    .start();

---

⚡ Current Quick Start (v1.1.0)

import fasttween.FastTween;
import fasttween.Easing;

// Create tween
FastTween tween = FastTween.to(target, "x", 100.0f)
    .duration(1.0f)
    .ease(Easing.OUT_QUAD)
    .start();

// Zero-allocation mode (pooled)
FastTween pooled = FastTween.pooledTo(target, "y", 200.0f)
    .duration(0.5f)
    .ease(Easing.IN_OUT_CUBIC)
    .start();

// Custom easing
tween.ease(t -> t * t * (3 - 2 * t)); // Smoothstep

✨ Key Features

• Zero-allocation mode (object pooling)
• 8 built-in easing functions: LINEAR, IN_QUAD, OUT_QUAD, IN_OUT_QUAD, IN_CUBIC, OUT_CUBIC, IN_OUT_CUBIC, ELASTIC
• Custom lambda easing support
• Property-based animation
• Callbacks (onComplete, onUpdate)
• Pause/resume/cancel
