Core Features

Tweening & Easing (AnimationCurve-Based)

Extension methods for clean, readable motion code:

transform.Move(destination, duration);
transform.EaseRotate(targetRotation, duration);
transform.EaseScale(targetScale, duration);

Supported operations include: - Move / MoveWorld - Rotate - Scale - MoveAlongPath - FadeAudio / CrossfadeAudio - FadeAlpha / ChangeColor - SnapToSibling / EaseSnapToSibling

Curves can be mirrored, ping-ponged, or customized.

Weighted Random Selection

Select elements with weighted probabilities:

var weighted = new WeightedElements<string>();
weighted.Add("Common", 70);
weighted.Add("Rare", 25);
weighted.Add("Epic", 5);

string result = weighted.GetRandom();

Object Pooling

Efficient GameObject reuse to reduce instantiation overhead.

Audio Pool

Play multiple overlapping sound effects without audio artifacts.
