Detailed Description

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

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

Constructor & Destructor Documentation

Ogre::RotationAffector::RotationAffector ( ParticleSystem * psys )

Default constructor.

Member Function Documentation

void Ogre::RotationAffector::_affectParticles ( ParticleSystem * pSystem,

Real timeElapsed

) [virtual]

See ParticleAffector.

Implements Ogre::ParticleAffector.

void Ogre::RotationAffector::_initParticle ( Particle * pParticle ) [virtual]

See ParticleAffector.

Reimplemented from Ogre::ParticleAffector.

void Ogre::ParticleAffector::addBaseParameters ( void ) [protected, inherited]

Internal method for setting up the basic parameter definitions for a subclass.

Remarks:
Because StringInterface holds a dictionary of parameters per class, subclasses need to call this to ask the base class to add it's parameters to their dictionary as well. Can't do this in the constructor because that runs in a non-virtual context.

The subclass must have called it's own createParamDictionary before calling this method.

Definition at line 68 of file OgreParticleAffector.h.

void Ogre::StringInterface::cleanupDictionary ( ) [static, inherited]

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.

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const [virtual, inherited]

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.

Definition at line 296 of file OgreStringInterface.h.
References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

bool Ogre::StringInterface::createParamDictionary ( const String & className ) [protected, inherited]

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:
This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

className the name of the class using the dictionary

Returns:
true if a new dictionary was created, false if it was already there

Definition at line 172 of file OgreStringInterface.h.
References Ogre::String.

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) const [inherited]

Definition at line 209 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) [inherited]

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.

Definition at line 196 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter ( const String & name ) const [virtual, inherited]

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:

name The name of the parameter to get

Returns:
String value of parameter, blank if not found

Definition at line 265 of file OgreStringInterface.h.
References Ogre::ParamCommand::doGet(), Ogre::ParamDictionary::getParamCommand(), and Ogre::String.

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.

const Radian& Ogre::RotationAffector::getRotationRangeEnd ( void ) const

Gets the maximum rotation of particles to be emitted.

const Radian& Ogre::RotationAffector::getRotationRangeStart ( void ) const

Gets the minimum rotation of particles to be emitted.

const Radian& Ogre::RotationAffector::getRotationSpeedRangeEnd ( void ) const

Gets the maximum rotation speed of particles to be emitted.

const Radian& Ogre::RotationAffector::getRotationSpeedRangeStart ( void ) const

Gets the minimum rotation speed of particles to be emitted.

const String& Ogre::ParticleAffector::getType ( void ) const [inherited]

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.

Definition at line 104 of file OgreParticleAffector.h.
References Ogre::String.

virtual bool Ogre::StringInterface::setParameter ( const String & name,

const String & value

) [virtual, 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:

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)

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

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

paramList Name/value pair list
