Member Function Documentation

virtual ParticleVisualData* Ogre::ParticleSystemRenderer::_createVisualData ( void  )
inlinevirtual

Create a new ParticleVisualData instance for attachment to a particle.

Remarks
If this renderer needs additional data in each particle, then this should be held in an instance of a subclass of ParticleVisualData, and this method should be overridden to return a new instance of it. The default behaviour is to return null.

Definition at line 98 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_destroyVisualData ( ParticleVisualData vis)
inlinevirtual

Destroy a ParticleVisualData instance.

Remarks
If this renderer needs additional data in each particle, then this should be held in an instance of a subclass of ParticleVisualData, and this method should be overridden to destroy an instance of it. The default behaviour is to do nothing.

Definition at line 106 of file OgreParticleSystemRenderer.h.

virtual SortMode Ogre::ParticleSystemRenderer::_getSortMode ( void  ) const
pure virtual

Gets the desired particles sort mode of this renderer.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_notifyAttached ( Node parent)
pure virtual
virtual void Ogre::ParticleSystemRenderer::_notifyCurrentCamera ( Camera cam)
pure virtual

Delegated to by ParticleSystem::_notifyCurrentCamera.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_notifyDefaultDimensions ( Real  width,
Real  height 
)
pure virtual

virtual void Ogre::ParticleSystemRenderer::_notifyParticleQuota ( size_t  quota)
pure virtual

Tells the renderer that the particle quota has changed.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_notifyParticleResized ( void  )
inlinevirtual

Optional callback notified when particles are resized individually.

Reimplemented in Ogre::BillboardParticleRenderer.

Definition at line 78 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_notifyParticleRotated ( void  )
inlinevirtual

Optional callback notified when particles are rotated.

Reimplemented in Ogre::BillboardParticleRenderer.

Definition at line 76 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_setMaterial ( MaterialPtr mat)
pure virtual

Sets the material this renderer must use; called by ParticleSystem.

Implemented in Ogre::BillboardParticleRenderer.

virtual void Ogre::ParticleSystemRenderer::_updateRenderQueue ( RenderQueue queue,
Camera camera,
const Camera lodCamera,
list< Particle * >::type &  currentParticles,
bool  cullIndividually 
)
pure virtual

Delegated to by ParticleSystem::_updateRenderQueue.

Remarks
The subclass must update the render queue using whichever Renderable instance(s) it wishes.

Implemented in Ogre::BillboardParticleRenderer.

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.

Definition at line 302 of file OgreStringInterface.h.

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

Definition at line 185 of file OgreStringInterface.h.

References OGRE_LOCK_MUTEX.

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

Definition at line 271 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

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.
virtual const String& Ogre::ParticleSystemRenderer::getType ( void  ) const
pure virtual

Gets the type of this renderer - must be implemented by subclasses.

Implemented in Ogre::BillboardParticleRenderer.

virtualinherited

Generic parameter setting method.

Remarks

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)
