This emitter emits particles from a single point, which is it’s position.
The initial direction of these particles can either be a single direction (i.e. a line), a random scattering inside a cone, or a random scattering in all directions, depending the 'angle' parameter, which is the angle across which to scatter the particles either side of the base direction of the emitter.
| Ogre::PointEmitter::PointEmitter | ( | ParticleSystem * | psys | ) |
Initialises a particle based on the emitter's approach and parameters.
See the _getEmissionCount method for details of why there is a separation between 'requested' emissions and actual initialised particles.
| pParticle | Pointer to a particle which must be initialised based on how this emitter starts particles. This is passed as a pointer rather than being created by the emitter so the ParticleSystem can reuse Particle instances, and can also set defaults itself. |
