# imageSequenceColumnCount

The number of columns for treating the particle image as a grid of animation frames.

```
var imageSequenceColumnCount: Int { get set }
```

## Discussion

To specify a sequence of frames for animating each particle, arrange the frames as a grid in a single image, as shown in [Figure 1](/documentation/scenekit/scnparticlesystem/1524153-particleimage#1965925). Then use this property and the [`imageSequenceRowCount`](/documentation/SceneKit/SCNParticleSystem/imageSequenceRowCount) property to specify the arrangement of frames in the image, and the [`imageSequenceInitialFrame`](/documentation/SceneKit/SCNParticleSystem/imageSequenceInitialFrame) and [`imageSequenceFrameRate`](/documentation/SceneKit/SCNParticleSystem/imageSequenceFrameRate) properties to define animation timing.

The default value is `1`. If the [`imageSequenceRowCount`](/documentation/SceneKit/SCNParticleSystem/imageSequenceRowCount) value is also `1` (the default), this specifies no animation for particle images.
