Constructor & Destructor Documentation

Ogre::ScaleAffector::ScaleAffector  
 

Default constructor.

Member Function Documentation

void Ogre::ScaleAffector::_affectParticles ParticleSystem   pSystem,
Real    timeElapsed
[virtual]
 

See ParticleAffector.

Implements Ogre::ParticleAffector.

Definition at line 53 of file OgreScaleAffector.cpp.

References Ogre::ParticleSystem::_getIterator(), Ogre::ParticleIterator::end(), Ogre::BillboardSet::getDefaultHeight(), Ogre::BillboardSet::getDefaultWidth(), Ogre::ParticleIterator::getNext(), Ogre::Billboard::getOwnHeight(), Ogre::Billboard::getOwnWidth(), Ogre::Billboard::hasOwnDimensions(), mScaleAdj, Ogre::Real, and Ogre::Billboard::setDimensions().

virtual void Ogre::ParticleAffector::_initParticle Particle   pParticle [virtual, inherited]
 

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:
pParticle  Pointer to a Particle to initialize.

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

Definition at line 81 of file OgreParticleAffector.h.

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.

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.

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

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

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.

References Ogre::ParamDictionary::getParameters(), and Ogre::ParameterList.

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.

void Ogre::ScaleAffector::setAdjust Real    rate
 

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

Parameters:
Rate  Sets 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.

Definition at line 81 of file OgreScaleAffector.cpp.

References mScaleAdj, and Ogre::Real.

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)
