Member Function Documentation

virtual ParticleVisualData* Ogre::ParticleSystemRenderer::_createVisualData (  void   )  [virtual]
 

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 92 of file OgreParticleSystemRenderer.h.

virtual void Ogre::ParticleSystemRenderer::_destroyVisualData (  ParticleVisualData *  vis  )  [virtual]
 

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 100 of file OgreParticleSystemRenderer.h.

Reimplemented in Ogre::BillboardParticleRenderer.

Definition at line 70 of file OgreParticleSystemRenderer.h.

std::list< Particle * > &  currentParticles,

Ogre::AllocatedObject< SceneObjAllocPolicy >::AllocatedObject (   )  [explicit, inherited]
 

Definition at line 55 of file OgreMemoryAllocatedObject.h.

static 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 300 of file OgreStringInterface.h.

References Ogre::ParamDictionary::mParamDefs.

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 176 of file OgreStringInterface.h.

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

Definition at line 213 of file OgreStringInterface.h.

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 200 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

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.
