Detailed Description

The PCZSceneNode is an extension used to store zone information and provide additional functionality for a given Ogre::SceneNode.

A PCZSceneNode contains a pointer to the home zone for the node and a list of all zones being visited by the node. The PCZSceneManager contains a STD::MAP of PCZSceneNodes which are keyed by the name of each node (each PCZSceneNode has an identical name to the scene node which it is associated with). This allows quick lookup of a given scenenode's PCZSceneNode by the scene manager.

Member Function Documentation

_update()

void Ogre::PCZSceneNode::_update ( bool  updateChildren, bool  parentHasChanged  )

overridevirtual

Internal method to update the Node.

Note

Updates this scene node and any relevant children to incorporate transforms etc. Don't call this yourself unless you are writing a SceneManager implementation.

Parameters

updateChildren	If true, the update cascades down to all children. Specify false if you wish to update children separately, e.g. because of a more selective SceneManager implementation.
parentHasChanged	This flag indicates that the parent transform has changed, so the child should retrieve the parent's transform and combine it with its own even if it hasn't changed itself.

Reimplemented from Ogre::SceneNode.

updateFromParentImpl()

void Ogre::PCZSceneNode::updateFromParentImpl ( ) const

overridevirtual

Class-specific implementation of _updateFromParent.

Remarks

Splitting the implementation of the update away from the update call itself allows the detail to be overridden without disrupting the general sequence of updateFromParent (e.g. raising events)

Reimplemented from Ogre::SceneNode.

createChildSceneNode() [1/2]

SceneNode* Ogre::PCZSceneNode::createChildSceneNode ( const Vector3 &  translate = Vector3::ZERO, const Quaternion &  rotate = Quaternion::IDENTITY  )

overridevirtual

Creates an unnamed new SceneNode as a child of this node.

Parameters

translate	Initial translation offset of child relative to parent
rotate	Initial rotation relative to parent

Reimplemented from Ogre::SceneNode.

createChildSceneNode() [2/2]

SceneNode* Ogre::PCZSceneNode::createChildSceneNode ( const String &  name, const Vector3 &  translate = Vector3::ZERO, const Quaternion &  rotate = Quaternion::IDENTITY  )

overridevirtual

Creates a new named SceneNode as a child of this node.

Remarks

This creates a child node with a given name, which allows you to look the node up from the parent which holds this collection of nodes.

Parameters

name	name of the node
translate	Initial translation offset of child relative to parent
rotate	Initial rotation relative to parent
