## Detailed Description

Interface for dynamic creation of scene nodes.

To be able to add custom scene nodes to Irrlicht and to make it possible for the scene manager to save and load those external scene nodes, simply implement this interface and register it in you scene manager via ISceneManager::registerSceneNodeFactory. Note: When implementing your own scene node factory, don't call ISceneNodeManager::grab() to increase the reference counter of the scene node manager. This is not necessary because the scene node manager will grab() the factory anyway, and otherwise cyclic references will be created and the scene manager and all its nodes won't get deallocated.

## Member Function Documentation

virtual ISceneNode* irr::scene::ISceneNodeFactory::addSceneNode | ( | const c8 * | typeName,
|  | ISceneNode * | parent = `0` |
| ) |  |  | `[pure virtual]`

adds a scene node to the scene graph based on its type name

Parameters:

  | typeName,: | Type name of the scene node to add.
  | parent,: | Parent scene node of the new node, can be null to add the scene node to the root.

Returns:
  Returns pointer to the new scene node or null if not successful. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

virtual ISceneNode* irr::scene::ISceneNodeFactory::addSceneNode | ( | ESCENE_NODE_TYPE | type,
|  | ISceneNode * | parent = `0` |
| ) |  |  | `[pure virtual]`

adds a scene node to the scene graph based on its type id

Parameters:

  | type,: | Type of the scene node to add.
  | parent,: | Parent scene node of the new node, can be null to add the scene node to the root.

Returns:
  Returns pointer to the new scene node or null if not successful. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

virtual u32 irr::scene::ISceneNodeFactory::getCreatableSceneNodeTypeCount | ( |  | ) | const`[pure virtual]`

returns amount of scene node types this factory is able to create

virtual ESCENE_NODE_TYPE irr::scene::ISceneNodeFactory::getCreateableSceneNodeType | ( | u32 | idx | ) | const`[pure virtual]`

returns type of a createable scene node type

Parameters:

  | idx,: | Index of scene node type in this factory. Must be a value between 0 and getCreatableSceneNodeTypeCount()

virtual const c8* irr::scene::ISceneNodeFactory::getCreateableSceneNodeTypeName | ( | ESCENE_NODE_TYPE | type | ) | const`[pure virtual]`

returns type name of a createable scene node type

Parameters:

  | type,: | Type of scene node.

Returns:
  : Returns name of scene node type if this factory can create the type, otherwise 0.

virtual const c8* irr::scene::ISceneNodeFactory::getCreateableSceneNodeTypeName | ( | u32 | idx | ) | const`[pure virtual]`

returns type name of a createable scene node type by index

Parameters:

  | idx,: | Index of scene node type in this factory. Must be a value between 0 and getCreatableSceneNodeTypeCount()
