Detailed Description

This class defines a ParticleAffector which applies randomness to the movement of the particles.

Remarks
This affector (see ParticleAffector) applies randomness to the movement of the particles by changing the direction vectors.
The most important parameter to control the effect is randomness. It controls the range in which changes are applied to each axis of the direction vector. The parameter scope can be used to limit the effect to a certain percentage of the particles.

Constructor & Destructor Documentation

Ogre::DirectionRandomiserAffector::DirectionRandomiserAffector ( ParticleSystem psys)

Default constructor.

Member Function Documentation

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

Definition at line 95 of file OgreParticleAffector.h.

void Ogre::ParticleAffector::addBaseParameters ( void  )
inlineprotectedinherited

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 78 of file OgreParticleAffector.h.

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.

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

References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

bool Ogre::StringInterface::createParamDictionary ( const String className)
inlineprotectedinherited

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
classNamethe name of the class using the dictionary
Returns
true if a new dictionary was created, false if it was already there

bool Ogre::DirectionRandomiserAffector::getKeepVelocity ( void  ) const

Gets flag which detemines whether particle speed is changed.

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.

Definition at line 218 of file OgreStringInterface.h.

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

Definition at line 223 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter ( const String name) const
inlinevirtualinherited

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

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.
Real Ogre::DirectionRandomiserAffector::getRandomness ( void  ) const

Gets the randomness to apply to the particles in a system.

Real Ogre::DirectionRandomiserAffector::getScope ( void  ) const

Gets the scope (percentage of particles which are randomised).

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.

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)
