/** An emitter class that holds three objects to control the creation of particles. |
|
These objects are a <I>counter</I>, a <I>placer</I> and a <I>shooter</I>. |
|
The counter controls the number of particles to be emitted at each frame; |
|
the placer must initialize the particle's position vector, while the shooter initializes |
|
its velocity vector. |
|
You can use the predefined counter/placer/shooter classes, or you can create your own. |
