# particleScaleSequence

The sequence used to specify the scale factor of a particle over its lifetime.

## Declaration

```swift
var particleScaleSequence: SKKeyframeSequence? { get set }
```

## Mentioned in

Animating Particle Properties Across Disparate Values Using Keyframe Sequence to effect Custom Interpolation

## Discussion

Discussion The default value is nil. If a non-nil value is specified, then the particleScale, particleScaleRange, and particleScaleSpeed properties are ignored. Instead, the sequence is used to specify the scale factor.
