188 Tutorial 4 Working With Particles

Now, over the butterfly particles’ lives, their color is tinted according to the Sunset Sky

gradient.

The gradient colors can easily be flipped.

To flip the gradient colors:

1 Click the Reverse Tags icon next to the color gradient. One arrow reverses the opacity

tags, and the other reverses the color tags.

The butterflies start out tinted red, and are tinted more yellow as they go.

2 Click the Reverse Tags icon again to restore the original gradient.

Applying Behaviors to Particles

For more lively butterflies, apply the Throw behavior to make them move across the

screen. Because you want the individual particles in the Butterflies emitter to move

rather than the emitter itself, apply the Throw behavior to the cell source, not the

emitter. That way, particles will move from the origin point of the emitter, rather than

along the path of a moving emitter.

To apply the Throw behavior to the butterfly:

1 In the Layers tab, select the Butterfly object under the Butterflies emitter.
