The Open Source Particle System for Actionscript 3 Development, Pulse-Particle System, allows Flash developers to quickly and easily set up a wide range of particle effects. There are two ways of using the system, through an object orientated API that gives full control over the system, or through a simplified object syntax.

Particle System Features

• Configurable rule based particle behavior
• Easily extensible
• Both a full featured object orientated syntax, and a simplified quick object syntax
• Flash .mxp extension for easy integration for designers
• Interactive particle explorer to create effects
