Chapter 8 Working With Particles 613
Particle System Examples
This section presents two examples of how to use particle systems to create very
different effects.
Example 1: Creating an Animated Background
This first example describes how to create an animated background using a single still
image. By using the parameters available in the Emitter tab, a single image can be
turned into a complex animated texture.
To create an animated background from a single image:
1 Drag a file into the Canvas. This example uses a simple graphic with a premultiplied
alpha channel.
2 With the new object selected, click the Make Particles icon in the Toolbar to turn it into
an emitter (or press E).
The original object is replaced with an emitter, but nothing happens yet because the
playhead is at the first frame of the project, and only one particle has been created.
3 In the Emitter tab of the Inspector, choose Circle from the Shape pop-up menu.
4 Choose Tile Fill from the Pattern pop-up menu.
