In this lesson you were introduced to the basic concepts of nParticles and the Nucleus dynamics system. In addition, you learned how to:

• Create nParticles by emitting them from a polygon object using a Surface type particle emitter.
• Set the size of the nParticles using the Radius attribute.
• Set the color of you nParticles.
• Set nParticle Collisions attributes to control the behavior of nParticles.
• Turn off nParticle self-collisions.
• Set the collision distance between self-colliding nParticles by setting Self Collide Width Scale.
