Instance Property

imageSequenceRowCount

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

Declaration

@property(nonatomic) NSUInteger imageSequenceRowCount;

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. Then use this property and the imageSequenceColumnCount property to specify the arrangement of frames in the image, and the imageSequenceInitialFrame and imageSequenceFrameRate properties to define animation timing.

The default value is 1. If the imageSequenceColumnCount value is also 1 (the default), this specifies no animation for particle images.
