Detailed Description

This plugin subclass of ParticleAffector allows you to alter the scale of particles.

Remarks
This class supplies the ParticleAffector implementation required to make the particle expand or contract in mid-flight.

Constructor & Destructor Documentation

◆ ScaleAffector()

Ogre::ScaleAffector::ScaleAffector ( ParticleSystem psys)

Default constructor.

Member Function Documentation

◆ _affectParticles()

void Ogre::ScaleAffector::_affectParticles ( ParticleSystem pSystem,
Real  timeElapsed 
)
virtual

◆ setAdjust()

void Ogre::ScaleAffector::setAdjust ( Real  rate)

Sets the scale adjustment to be made per second to particles.

Parameters
rateSets the adjustment to be made to the x and y scale components per second. These values will be added to the scale of all particles every second, scaled over each frame for a smooth adjustment.

◆ getAdjust()

Real Ogre::ScaleAffector::getAdjust ( void  ) const

Gets the scale adjustment to be made per second to particles.

◆ _initParticle()

virtual void Ogre::ParticleAffector::_initParticle ( Particle pParticle)
inlinevirtualinherited

Method called to allow the affector to initialize all newly created particles in the system.

Remarks
This is where the affector gets the chance to initialize it's effects to the particles of a system. The affector is expected to initialize some or all of the particles in the system passed to it, depending on the affector's approach.
Parameters
pParticlePointer to a Particle to initialize.

Reimplemented in Ogre::RotationAffector, and Ogre::ColourImageAffector.

◆ getType()

const String& Ogre::ParticleAffector::getType ( void  ) const
inlineinherited

Returns the name of the type of affector.

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

◆ getParamDictionary() [1/2]

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  )
inlineinherited

Retrieves the parameter dictionary for this class.

Remarks
Only valid to call this after createParamDictionary.
Returns
Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

◆ getParamDictionary() [2/2]

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void  ) const
inlineinherited

◆ getParameters()

const ParameterList& Ogre::StringInterface::getParameters ( void  ) const
inherited

Retrieves a list of parameters valid for this object.

Returns
A reference to a static list of ParameterDef objects.

◆ setParameter()

bool Ogre::StringInterface::setParameter ( const String name,
const String value 
)
inherited

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
nameThe name of the parameter to set
valueString 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)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ setParameterList()

void Ogre::StringInterface::setParameterList ( const NameValuePairList paramList)
inherited

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
paramListName/value pair list

◆ getParameter()

String Ogre::StringInterface::getParameter ( const String name) const
inlineinherited

Generic parameter retrieval method.

Remarks
Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.
Parameters
nameThe name of the parameter to get
Returns
String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

◆ copyParametersTo()

void Ogre::StringInterface::copyParametersTo ( StringInterface dest) const
inlineinherited

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

References Ogre::StringInterface::setParameter().

◆ 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.
