As posted in the forums: [ http://forum.unity3d.com/threads/65273-Toggle-Particle-Emitter-ON-OFF ][1]
I would like that someone take a look at that post, and try to answer my question about the 'emit' property/variable in the ParticleEmitter class.
The question is: How is the 'emit' variable used, what effect can be arrived at using it? As you will see in the post mentioned above, I was not able to get results using 'emit' but was successful while using renderer.enable/disable.
