Use this skill to make objects move, spin, bob, pulse, or animate.

Trigger Phrases

•"spin", "rotate", "spinning"
•"bob", "float", "hover"
•"pulse", "grow", "shrink"
•"animate", "moving"
•"wiggle", "shake"

When to Apply (Automatically)

Add animation when:

•Collectibles (coins spin, gems bob)
•Power-ups (pulse/glow)
•Decorations (flags wave, fans spin)
•Feedback (damage shake, collect bounce)
•Idle objects (breathing, shifting)

Simple Animation Scripts

Spin/Rotate

csharp

public class Spinner : MonoBehaviour
{
    public Vector3 rotationSpeed = new Vector3(0, 90, 0);

    void Update()
    {
        transform.Rotate(rotationSpeed * Time.deltaTime);
    }
}

Bob/Float

csharp

public class Bobber : MonoBehaviour
{
    public float amplitude = 0.3f;
    public float frequency = 1f;

    private Vector3 startPos;

    void Start() => startPos = transform.localPosition;

    void Update()
    {
        Vector3 pos = startPos;
        pos.y += Mathf.Sin(Time.time * frequency * Mathf.PI * 2) * amplitude;
        transform.localPosition = pos;
    }
}

Pulse/Scale

csharp

public class Pulser : MonoBehaviour
{
    public float minScale = 0.9f;
    public float maxScale = 1.1f;
    public float speed = 2f;

    private Vector3 originalScale;

    void Start() => originalScale = transform.localScale;

    void Update()
    {
        float t = (Mathf.Sin(Time.time * speed) + 1) / 2; // 0 to 1
        float scale = Mathf.Lerp(minScale, maxScale, t);
        transform.localScale = originalScale * scale;
    }
}

Spin + Bob Combined (Common for Collectibles)

csharp

public class CollectibleAnimation : MonoBehaviour
{
    public float spinSpeed = 90f;
    public float bobAmplitude = 0.2f;
    public float bobFrequency = 1f;

    private Vector3 startPos;

    void Start() => startPos = transform.localPosition;

    void Update()
    {
        // Spin
        transform.Rotate(0, spinSpeed * Time.deltaTime, 0);

        // Bob
        Vector3 pos = startPos;
        pos.y += Mathf.Sin(Time.time * bobFrequency * Mathf.PI * 2) * bobAmplitude;
        transform.localPosition = pos;
    }
}

Shake (for damage feedback)

csharp

public class Shaker : MonoBehaviour
{
    public float shakeDuration = 0.3f;
    public float shakeMagnitude = 0.1f;

    private Vector3 originalPos;
    private float shakeTimeRemaining;

    void Start() => originalPos = transform.localPosition;

    public void Shake()
    {
        shakeTimeRemaining = shakeDuration;
    }

    void Update()
    {
        if (shakeTimeRemaining > 0)
        {
            transform.localPosition = originalPos + Random.insideUnitSphere * shakeMagnitude;
            shakeTimeRemaining -= Time.deltaTime;
        }
        else
        {
            transform.localPosition = originalPos;
        }
    }
}

Swing/Pendulum

csharp

public class Swinger : MonoBehaviour
{
    public float angle = 30f;
    public float speed = 2f;

    void Update()
    {
        float rot = Mathf.Sin(Time.time * speed) * angle;
        transform.localRotation = Quaternion.Euler(0, 0, rot);
    }
}

Animation Presets

Object Type	Animation	Settings
Coin	Spin + Bob	spinSpeed: 90, bobAmp: 0.2
Gem	Bob + Pulse	bobAmp: 0.15, pulse: 0.9-1.1
Power-up	Pulse + Glow	pulse: 0.8-1.2, emissive
Flag	Swing	angle: 15, speed: 3
Floating platform	Bob	bobAmp: 0.5, freq: 0.5
Enemy idle	Pulse (breathing)	0.95-1.05, speed: 1

Output to User

Describe the motion:

•"The coins spin and float up and down"
•"Power-ups pulse with a glow effect"
•"The platform moves up and down slowly"
