## Member Function Documentation

virtual s32 irr::scene::IParticleEmitter::emitt | ( | u32 | now,
|  | u32 | timeSinceLastCall,
|  | SParticle *& | outArray |
| ) |  |  | `[pure virtual]`

Prepares an array with new particles to emitt into the system.

Parameters:

  | now | Current time.
  | timeSinceLastCall | Time elapsed since last call, in milliseconds.
  | outArray | Pointer which will point to the array with the new particles to add into the system.

Returns:
  Amount of new particles in the array. Can be 0.
