## Detailed Description

Abstract class defining the interface to be implemented by particle emitters.

Particle emitters are the sources of particles in a particle system. This class defines the ParticleEmitter interface, and provides a basic implementation for tasks which most emitters will do (these are of course overridable). Particle emitters can be grouped into types, e.g. 'point' emitters, 'box' emitters etc; each type will create particles with a different starting point, direction and velocity (although within the types you can configure the ranges of these parameters).

  Because there are so many types of emitters you could use, OGRE chooses not to dictate the available types. It comes with some in-built, but allows plugins or applications to extend the emitter types available. This is done by subclassing ParticleEmitter to have the appropriate emission behaviour you want, and also creating a subclass of ParticleEmitterFactory which is responsible for creating instances of your new emitter type. You register this factory with the ParticleSystemManager using addEmitterFactory, and from then on emitters of this type can be created either from code or through text particle scripts by naming the type.

  This same approach is used for ParticleAffectors (which modify existing particles per frame). This means that OGRE is particularly flexible when it comes to creating particle system effects, with literally infinite combinations of emitter and affector types, and parameters within those types.

## Constructor & Destructor Documentation

## ParticleEmitter()

Ogre::ParticleEmitter::ParticleEmitter | ( | ParticleSystem * | psys | ) |

Referenced by Ogre::AreaEmitter::AreaEmitter().

## ~ParticleEmitter()

virtual Ogre::ParticleEmitter::~ParticleEmitter | ( |  | ) |

virtual

Virtual destructor essential.

## Member Function Documentation

## setPosition()

virtual void Ogre::ParticleEmitter::setPosition | ( | const Vector3 & | pos | ) |

virtual

Sets the position of this emitter relative to the particle system center.

## getPosition()

virtual const Vector3 & Ogre::ParticleEmitter::getPosition | ( | void |  | ) | const

virtual

Returns the position of this emitter relative to the center of the particle system.

## setDirection()

virtual void Ogre::ParticleEmitter::setDirection | ( | const Vector3 & | direction | ) |

virtual

Sets the direction of the emitter.

Most emitters will have a base direction in which they emit particles (those which emit in all directions will ignore this parameter). They may not emit exactly along this vector for every particle, many will introduce a random scatter around this vector using the angle property.

Note
  This resets the up vector.

Parameters

  direction | The base direction for particles emitted.

Reimplemented in Ogre::AreaEmitter.

## getDirection()

virtual const Vector3 & Ogre::ParticleEmitter::getDirection | ( | void |  | ) | const

virtual

Returns the base direction of the emitter.

## setUp()

virtual void Ogre::ParticleEmitter::setUp | ( | const Vector3 & | up | ) |

virtual

Sets the notional up vector of the emitter.

Many emitters emit particles from within a region, and for some that region is not circularly symmetric about the emitter direction. The up vector allows such emitters to be orientated about the direction vector.

Parameters

  up | The base direction for particles emitted. It must be perpendicular to the direction vector.

## getUp()

virtual const Vector3 & Ogre::ParticleEmitter::getUp | ( | void |  | ) | const

virtual

Returns the up vector of the emitter.

## setDirPositionReference()

virtual void Ogre::ParticleEmitter::setDirPositionReference | ( | const Vector3 & | position,
|  | bool | enable )

virtual

Sets the direction of the emitter.

Some particle effects need to emit particles in many random directions, but still following some rules; like not having them collide against each other. Very useful for explosions and implosions (when velocity is negative)

Note
  Although once enabled mDirPositionRef will supersede mDirection; calling setDirection() may still be needed to setup a custom up vector.

Parameters

  position | The reference position in which the direction of the particles will be calculated from, also taking into account the particle's position at the time of emission.
  enable | True to use mDirPositionRef, false to use the default behaviour with mDirection

## getDirPositionReference()

virtual const Vector3 & Ogre::ParticleEmitter::getDirPositionReference | ( |  | ) | const

virtual

Returns the position reference to generate direction of emitted particles.

## getDirPositionReferenceEnabled()

virtual bool Ogre::ParticleEmitter::getDirPositionReferenceEnabled | ( |  | ) | const

virtual

Returns whether direction or position reference is used.

## setAngle()

virtual void Ogre::ParticleEmitter::setAngle | ( | const Radian & | angle | ) |

virtual

Sets the maximum angle away from the emitter direction which particle will be emitted.

Whilst the direction property defines the general direction of emission for particles, this property defines how far the emission angle can deviate away from this base direction. This allows you to create a scatter effect - if set to 0, all particles will be emitted exactly along the emitters direction vector, whereas if you set it to 180 degrees or more, particles will be emitted in a sphere, i.e. in all directions.

Parameters

  angle | Maximum angle which initial particle direction can deviate from the emitter base direction vector.

## getAngle()

virtual const Radian & Ogre::ParticleEmitter::getAngle | ( | void |  | ) | const

virtual

Returns the maximum angle which the initial particle direction can deviate from the emitters base direction.

## setParticleVelocity() [1/2]

virtual void Ogre::ParticleEmitter::setParticleVelocity | ( | Real | speed | ) |

virtual

Sets the initial velocity of particles emitted.

This method sets a constant speed for emitted particles. See the alternate version of this method which takes 2 parameters if you want a variable speed.

Parameters

  speed | The initial speed in world units per second which every particle emitted starts with.

## setParticleVelocity() [2/2]

virtual void Ogre::ParticleEmitter::setParticleVelocity | ( | Real | min,
|  | Real | max )

virtual

Sets the initial velocity range of particles emitted.

This method sets the range of starting speeds for emitted particles. See the alternate version of this method which takes 1 parameter if you want a constant speed. This emitter will randomly choose a speed between the minimum and maximum for each particle.

Parameters

  max | The maximum speed in world units per second for the initial particle speed on emission.
  min | The minimum speed in world units per second for the initial particle speed on emission.

## setMinParticleVelocity()

virtual void Ogre::ParticleEmitter::setMinParticleVelocity | ( | Real | min | ) |

virtual

Returns the minimum particle velocity.

## setMaxParticleVelocity()

virtual void Ogre::ParticleEmitter::setMaxParticleVelocity | ( | Real | max | ) |

virtual

Returns the maximum particle velocity.

## getParticleVelocity()

virtual Real Ogre::ParticleEmitter::getParticleVelocity | ( | void |  | ) | const

virtual

Returns the initial velocity of particles emitted.

## getMinParticleVelocity()

virtual Real Ogre::ParticleEmitter::getMinParticleVelocity | ( | void |  | ) | const

virtual

Returns the minimum particle velocity.

## getMaxParticleVelocity()

virtual Real Ogre::ParticleEmitter::getMaxParticleVelocity | ( | void |  | ) | const

virtual

Returns the maximum particle velocity.

## setEmissionRate()

virtual void Ogre::ParticleEmitter::setEmissionRate | ( | Real | particlesPerSecond | ) |

virtual

Sets the emission rate for this emitter.

This method tells the emitter how many particles per second should be emitted. The emitter subclass does not have to emit these in a continuous burst - this is a relative parameter and the emitter may choose to emit all of the second's worth of particles every half-second for example. This is controlled by the emitter's getEmissionCount method.

  Also, if the ParticleSystem's particle quota is exceeded, not all the particles requested may be actually emitted.

Parameters

  particlesPerSecond | The number of particles to be emitted every second.

## getEmissionRate()

virtual Real Ogre::ParticleEmitter::getEmissionRate | ( | void |  | ) | const

virtual

Returns the emission rate set for this emitter.

## setTimeToLive() [1/2]

virtual void Ogre::ParticleEmitter::setTimeToLive | ( | Real | ttl | ) |

virtual

Sets the lifetime of all particles emitted.

The emitter initialises particles with a time-to-live (TTL), the number of seconds a particle will exist before being destroyed. This method sets a constant TTL for all particles emitted. Note that affectors are able to modify the TTL of particles later.

  Also see the alternate version of this method which takes a min and max TTL in order to have the TTL vary per particle.

Parameters

  ttl | The number of seconds each particle will live for.

## setTimeToLive() [2/2]

virtual void Ogre::ParticleEmitter::setTimeToLive | ( | Real | minTtl,
|  | Real | maxTtl )

virtual

Sets the range of lifetime for particles emitted.

The emitter initialises particles with a time-to-live (TTL), the number of seconds a particle will exist before being destroyed. This method sets a range for the TTL for all particles emitted; the ttl may be randomised between these 2 extremes or will vary some other way depending on the emitter. Note that affectors are able to modify the TTL of particles later.

  Also see the alternate version of this method which takes a single TTL in order to set a constant TTL for all particles.

Parameters

  minTtl | The minimum number of seconds each particle will live for. Must be non-negative!
  maxTtl | The maximum number of seconds each particle will live for. Must be non-negative!

## setMinTimeToLive()

virtual void Ogre::ParticleEmitter::setMinTimeToLive | ( | Real | min | ) |

virtual

Sets the minimum time each particle will live for.

Must be non-negative!

## setMaxTimeToLive()

virtual void Ogre::ParticleEmitter::setMaxTimeToLive | ( | Real | max | ) |

virtual

Gets the minimum time each particle will live for.

## getMaxTimeToLive()

virtual Real Ogre::ParticleEmitter::getMaxTimeToLive | ( | void |  | ) | const

virtual

Gets the maximum time each particle will live for.

## setColour() [1/2]

virtual void Ogre::ParticleEmitter::setColour | ( | const ColourValue & | colour | ) |

virtual

Sets the initial colour of particles emitted.

Particles have an initial colour on emission which the emitter sets. This method sets this colour. See the alternate version of this method which takes 2 colours in order to establish a range of colours to be assigned to particles.

Parameters

  colour | The colour which all particles will be given on emission.

## setColour() [2/2]

virtual void Ogre::ParticleEmitter::setColour | ( | const ColourValue & | colourStart,
|  | const ColourValue & | colourEnd )

virtual

Sets the range of colours for emitted particles.

Particles have an initial colour on emission which the emitter sets. This method sets the range of this colour. See the alternate version of this method which takes a single colour in order to set a constant colour for all particles. Emitters may choose to randomly assign a colour in this range, or may use some other method to vary the colour.

Parameters

  colourStart | The start of the colour range
  colourEnd | The end of the colour range

## setColourRangeStart()

virtual void Ogre::ParticleEmitter::setColourRangeStart | ( | const ColourValue & | colour | ) |

virtual

Sets the minimum colour of particles to be emitted.

## setColourRangeEnd()

virtual void Ogre::ParticleEmitter::setColourRangeEnd | ( | const ColourValue & | colour | ) |

## getColourRangeEnd()

virtual const ColourValue & Ogre::ParticleEmitter::getColourRangeEnd | ( | void |  | ) | const

virtual

Gets the maximum colour of particles to be emitted.

## _getEmissionCount()

virtual unsigned short Ogre::ParticleEmitter::_getEmissionCount | ( | Real | timeElapsed | ) |

inline virtual

Gets the number of particles which this emitter would like to emit based on the time elapsed.

For efficiency the emitter does not actually create new Particle instances (these are reused by the ParticleSystem as existing particles 'die'). The implementation for this method must return the number of particles the emitter would like to emit given the number of seconds which have elapsed (passed in as a parameter).

  Based on the return value from this method, the ParticleSystem class will call _initParticle once for each particle it chooses to allow to be emitted by this emitter. The emitter should not track these _initParticle calls, it should assume all emissions requested were made (even if they could not be because of particle quotas).

## _initParticle()

virtual void Ogre::ParticleEmitter::_initParticle | ( | Particle * | pParticle | ) |

inline virtual

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.

Parameters

  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.

Reimplemented in Ogre::BoxEmitter, Ogre::CylinderEmitter, Ogre::EllipsoidEmitter, Ogre::HollowEllipsoidEmitter, Ogre::PointEmitter, and Ogre::RingEmitter.

References Ogre::Particle::Particle(), and Ogre::Particle::setDimensions().

## getType()

const String & Ogre::ParticleEmitter::getType | ( | void |  | ) | const

inline

Returns the name of the type of emitter.

This property is useful for determining the type of emitter procedurally so another can be created.

## setEnabled()

virtual void Ogre::ParticleEmitter::setEnabled | ( | bool | enabled | ) |

virtual

Sets whether or not the emitter is enabled.

You can turn an emitter off completely by setting this parameter to false.

virtual

Gets the flag indicating if this emitter is enabled or not.

## setStartTime()

virtual void Ogre::ParticleEmitter::setStartTime | ( | Real | startTime | ) |

virtual

Sets the 'start time' of this emitter.

By default an emitter starts straight away as soon as a ParticleSystem is first created, or also just after it is re-enabled. This parameter allows you to set a time delay so that the emitter does not 'kick in' until later.

Parameters

  startTime | The time in seconds from the creation or enabling of the emitter.

virtual

Sets the duration of the emitter.

By default emitters run indefinitely (unless you manually disable them). By setting this parameter, you can make an emitter turn off on it's own after a set number of seconds. It will then remain disabled until either setEnabled(true) is called, or if the 'repeatAfter' parameter has been set it will also repeat after a number of seconds.

  Also see the alternative version of this method which allows you to set a min and max duration for a random variable duration.

Parameters

  duration | The duration in seconds.
