Ogre::MovableObjectFactory::MovableObjectFactory | ( |  | ) |

## Member Function Documentation

void Ogre::MovableObjectFactory::_notifyTypeFlags | ( | unsigned long | flag | ) |

Notify this factory of the type mask to apply.

Remarks:
  This should normally only be called by Root in response to a 'true' result from requestTypeMask. However, you can actually use it yourself if you're careful; for example to assign the same mask to a number of different types of object, should you always wish them to be treated the same in queries.

virtual MovableObject* Ogre::MovableObjectFactory::createInstance | ( | const String & | name,
|  | SceneManager * | manager,
|  | const NameValuePairList * | params = `0`
| ) | `[virtual]`

Create a new instance of the object.

Parameters:

  | name | The name of the new object
  | manager | The SceneManager instance that will be holding the instance once created.
  | params | Name/value pair list of additional parameters required to construct the object (defined per subtype). Optional.

virtual MovableObject* Ogre::MovableObjectFactory::createInstanceImpl | ( | const String & | name,
|  | const NameValuePairList * | params = `0`
| ) | `[protected, pure virtual]`

| Internal implementation of create method - must be overridden. Implemented in Ogre::BillboardChainFactory, Ogre::BillboardSetFactory, Ogre::EntityFactory, Ogre::LightFactory, Ogre::ManualObjectFactory, Ogre::ParticleSystemFactory, and Ogre::RibbonTrailFactory.

virtual void Ogre::MovableObjectFactory::destroyInstance | ( | MovableObject * | obj | ) | `[pure virtual]`

| Destroy an instance of the object. Implemented in Ogre::BillboardChainFactory, Ogre::BillboardSetFactory, Ogre::EntityFactory, Ogre::LightFactory, Ogre::ManualObjectFactory, Ogre::ParticleSystemFactory, and Ogre::RibbonTrailFactory.

virtual const String& Ogre::MovableObjectFactory::getType | ( | void |  | ) | const`[pure virtual]`

| Get the type of the object to be created. Implemented in Ogre::BillboardChainFactory, Ogre::BillboardSetFactory, Ogre::EntityFactory, Ogre::LightFactory, Ogre::ManualObjectFactory, Ogre::ParticleSystemFactory, and Ogre::RibbonTrailFactory.

unsigned long Ogre::MovableObjectFactory::getTypeFlags | ( | void |  | ) | const

Gets the type flag for this factory.

Remarks:
  A type flag is like a query flag, except that it applies to all instances of a certain type of object.

Definition at line 431 of file OgreMovableObject.h.

virtual bool Ogre::MovableObjectFactory::requestTypeFlags | ( | void |  | ) | const`[virtual]`

Does this factory require the allocation of a 'type flag', used to selectively include / exclude this type from scene queries?

Remarks:
  The default implementation here is to return 'false', ie not to request a unique type mask from Root. For objects that never need to be excluded in SceneQuery results, that's fine, since the default implementation of MovableObject::getTypeFlags is to return all ones, hence matching any query type mask. However, if you want the objects created by this factory to be filterable by queries using a broad type, you have to give them a (preferably unique) type mask - and given that you don't know what other MovableObject types are registered, Root will allocate you one.
