Detailed Description

Particle emitter which emits particles randomly from points inside an area (box, sphere, ellipsoid whatever subclasses choose to be).

Remarks: This is an empty superclass and needs to be subclassed. Basic particle emitter emits particles from/in an (unspecified) area. 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.

◆ _getEmissionCount()

unsigned short Ogre::AreaEmitter::_getEmissionCount ( Real timeElapsed )

virtual

See ParticleEmitter.

Implements Ogre::ParticleEmitter.

◆ _initParticle()

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

inlinevirtualinherited

Initialises a particle based on the emitter's approach and parameters.

Remarks: 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::RingEmitter, Ogre::PointEmitter, Ogre::HollowEllipsoidEmitter, Ogre::EllipsoidEmitter, Ogre::CylinderEmitter, and Ogre::BoxEmitter.

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )

staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlinevirtualinherited

Method for copying this object's parameters to another object.

Remarks: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters

dest	Pointer to object to have it's parameters set the same as this object.

◆ resetDimensions()

void Ogre::Particle::resetDimensions ( )

inherited

Utility method to reset this particle.

Referenced by Ogre::ParticleEmitter::_initParticle().

◆ setAngle()

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

virtualinherited

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

Remarks: 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.

◆ setColour() [1/2]

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

virtualinherited

Sets the initial colour of particles emitted.

Remarks: 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
	)

virtualinherited

Sets the range of colours for emitted particles.

Remarks: 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

◆ setColourRangeEnd()

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

virtualinherited

Sets the maximum colour of particles to be emitted.

◆ setColourRangeStart()

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

virtualinherited

Sets the minimum colour of particles to be emitted.

◆ setDepth()

void Ogre::AreaEmitter::setDepth ( Real Depth )

Sets the depth (local y size) of the emitter.

◆ setDimensions()

void Ogre::Particle::setDimensions	(	Real	width,
		Real	height
	)

inherited

Sets the width and height for this particle.

Remarks: Note that it is most efficient for every particle in a ParticleSystem to have the same dimensions. If you choose to alter the dimensions of an individual particle the set will be less efficient. Do not call this method unless you really need to have different particle dimensions within the same set. Otherwise just call the ParticleSystem::setDefaultDimensions method instead.

◆ setDirection()

void Ogre::AreaEmitter::setDirection ( const Vector3 & direction )

virtual

Overloaded to update the trans.

matrix

Reimplemented from Ogre::ParticleEmitter.

◆ setDirPositionReference()

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

virtualinherited

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

◆ setDuration() [1/2]

virtual void Ogre::ParticleEmitter::setDuration ( Real duration )

virtualinherited

Sets the duration of the emitter.

Remarks: 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.

◆ setDuration() [2/2]

virtual void Ogre::ParticleEmitter::setDuration	(	Real	min,
		Real	max
	)

virtualinherited

Sets the range of random duration for this emitter.

Remarks: 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 random 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 constant duration.

Parameters

min	The minimum duration in seconds.
max	The minimum duration in seconds.

◆ setEmissionRate()

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

virtualinherited

Sets the emission rate for this emitter.

Remarks: 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.

◆ setEmitted()

virtual void Ogre::ParticleEmitter::setEmitted ( bool emitted )

virtualinherited

Generic parameter setting method.

Remarks: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

virtualinherited

Generic multiple parameter setting method.

Remarks: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

paramList Name/value pair list

◆ setParticleVelocity() [1/2]

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

virtualinherited

Sets the initial velocity range of particles emitted.

Remarks: 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.

◆ setParticleVelocity() [2/2]

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

virtualinherited

Sets the initial velocity of particles emitted.

Remarks: 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.

◆ setPosition()

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

virtualinherited

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

◆ setRepeatDelay() [1/2]

virtual void Ogre::ParticleEmitter::setRepeatDelay ( Real duration )

virtualinherited

Sets the time between repeats of the emitter.

Remarks: By default emitters run indefinitely (unless you manually disable them). However, if you manually disable the emitter (by calling setEnabled(false), or it's duration runs out, it will cease to emit

: 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.

◆ setRepeatDelay() [2/2]

virtual void Ogre::ParticleEmitter::setRepeatDelay	(	Real	min,
		Real	max
	)

virtualinherited

Sets the range of random duration for this emitter.

Remarks: 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 random 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 constant duration.

Parameters

min	The minimum duration in seconds.
max	The minimum duration in seconds.

◆ setRotation()

void Ogre::Particle::setRotation ( const Radian & rad )

inherited

Sets the current rotation.

◆ setSize() [1/2]

void Ogre::AreaEmitter::setSize ( const Vector3 & size )

Sets the size of the area from which particles are emitted.

Parameters

size	Vector describing the size of the area. The area extends around the center point by half the x, y and z components of this vector. The box is aligned such that it's local Z axis points along it's direction (see setDirection)

◆ setSize() [2/2]

void Ogre::AreaEmitter::setSize	(	Real	x,
		Real	y,
		Real	z
	)

Sets the size of the area from which particles are emitted.

Parameters

x,y,z Individual axis lengths describing the size of the area. The area extends around the center point by half the x, y and z components of this vector. The box is aligned such that it's local Z axis points along it's direction (see setDirection)

◆ setStartTime()

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

virtualinherited

Sets the 'start time' of this emitter.

Remarks: 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.

◆ setTimeToLive() [1/2]

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

virtualinherited

Sets the range of lifetime for particles emitted.

Remarks: 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!

◆ setTimeToLive() [2/2]

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

virtualinherited

Sets the lifetime of all particles emitted.

Remarks: 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.

◆ setUp()

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

virtualinherited

Sets the notional up vector of the emitter.

Remarks: 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.

◆ setWidth()

void Ogre::AreaEmitter::setWidth ( Real width )

Sets the width (local x size) of the emitter.
