Guidance for using PrimeTween, a Unity library for smoothly changing values over time to create animations. It covers interface animations, gameplay effects, camera effects, and animation sequences.

In plain words
What is it for?
Use it to animate menus and interface elements, damage numbers and pickups, cameras, and other timed in-game effects.
Why use it?
It gives developers established patterns for moving, scaling, rotating, shaking, and sequencing Unity objects.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tools-unity-primetween scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PrimeTween

Overview

PrimeTween is a high-performance tweening library for Unity with zero allocations and excellent performance. This skill covers common patterns for UI animations, gameplay effects, and sequencing.

When to Use

  • UI animations (fade, scale, move)
  • Gameplay animations (damage numbers, pickups)
  • Camera effects
  • Value interpolation
  • Complex animation sequences

Basic Tweens

Transform Tweens

using PrimeTween;

public class TransformAnimator : MonoBehaviour
{
    public void MoveToPosition(Vector3 target, float duration)
    {
        Tween.Position(transform, target, duration);
    }
    
    public void MoveWithEase(Vector3 target, float duration, Ease ease)
    {
        Tween.Position(transform, target, duration, ease);
    }
    
    public void ScalePunch()
    {
        Tween.Scale(transform, 1.2f, 0.1f, Ease.OutQuad)
            .Chain(Tween.Scale(transform, 1f, 0.2f, Ease.OutElastic));
    }
    
    public void Rotate360(float duration)
    {
        Tween.Rotation(transform, Quaternion.Euler(0, 360, 0), duration)
            .SetRelative();
    }
    
    public void ShakePosition(float intensity, float duration)
    {
        Tween.ShakeLocalPosition(transform, intensity, duration);
    }
}

UI Tweens

public class UIAnimator : MonoBehaviour
{
    [SerializeField] private CanvasGroup _canvasGroup;
    [SerializeField] private RectTransform _rectTransform;
    
    public Tween FadeIn(float duration = 0.3f)
    {
        _canvasGroup.alpha = 0f;
        return Tween.Alpha(_canvasGroup, 1f, duration, Ease.OutQuad);
    }
    
    public Tween FadeOut(float duration = 0.2f)
    {
        return Tween.Alpha(_canvasGroup, 0f, duration, Ease.InQuad);
    }
    
    public Tween SlideIn(Vector2 fromOffset, float duration = 0.3f)
    {
        Vector2 targetPos = _rectTransform.anchoredPosition;
        _rectTransform.anchoredPosition = targetPos + fromOffset;
        return Tween.UIAnchoredPosition(_rectTransform, targetPos, duration, Ease.OutCubic);
    }
    
    public Tween PopIn(float duration = 0.4f)
    {
        _rectTransform.localScale = Vector3.zero;
        return Tween.Scale(_rectTransform, 1f, duration, Ease.OutBack);
    }
    
    public Tween PopOut(float duration = 0.2f)
    {
        return Tween.Scale(_rectTransform, 0f, duration, Ease.InBack);
    }
}
