| Class Summary | 
| Attract | Represents a point in space that attracts particles to 
 that point based on the distance between the particle 
 and the attracting point. | 
| Bounce | A simulation of Newton�s Law of Restitution for 
 Instantaneous Collisions. |

| Gravity | A directional gravity influence. | 
| Kill | Assumes instant death upon collision between the
 "ground" and the particle. | 
| ParticleAgeAlpha | A particle age alpha object produces a value, called the 
 alpha value, between 0.0 and 1.0, inclusive. | 
| Repulse | Represents a point in space that repulses (accelerates away)
 particles from that point based on the distance between the
 particle and the repulsing point. |
