RenderWindow * | createRenderWindow (const String &name, unsigned int width, unsigned int height, bool fullScreen, const NameValuePairList *miscParams=0)
  | Creates a new rendering window. Remarks: This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation. After creation, this window can be retrieved using getRenderTarget(). Parameters:
  | name | The name of the window. Used in other methods later like setRenderTarget and getRenderWindow.
  | width | The width of the new window.
  | height | The height of the new window.
  | fullScreen | Specify true to make the window full screen without borders, title bar or menu bar.
  | miscParams | A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platorms unless indicated otherwise:
Key: "title" Description: The title of the window that will appear in the title bar Values: string Default: RenderTarget name Key: "colourDepth" Description: Colour depth of the resulting rendering window; only applies if fullScreen is set. Values: 16 or 32 Default: desktop depth Notes: [W32 specific] Key: "left" Description: screen x coordinate from left Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen Key: "top" Description: screen y coordinate from top Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen Key: "depthBuffer" [DX9 specific] Description: Use depth buffer Values: false or true Default: true Key: "externalWindowHandle" [API specific] Description: External window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) for GLX Default: 0 (None) Key: "externalGLControl" [Win32 OpenGL specific] Description: Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls. The Ogre OpenGL context can be retrieved after Ogre initialisation by calling wglGetCurrentDC() and wglGetCurrentContext(). It is only used when the externalWindowHandle parameter is used. Values: true, false Default: false Key: "externalGLContext" [Win32 OpenGL specific] Description: Use an externally created GL context Values: <Context as="" unsigned="" long>=""> Default: 0 (create own context) Key: "parentWindowHandle" [API specific] Description: Parent window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong for GLX (display*:screen:windowHandle) Default: 0 (None) Key: "FSAA" Description: Full screen antialiasing factor Values: 0,2,4,6,... Default: 0 Key: "displayFrequency" Description: Display frequency rate, for fullscreen mode Values: 60...?

## Detailed Description

The root class of the Ogre system.

Remarks:
  The Ogre::Root class represents a starting point for the client application. From here, the application can gain access to the fundamentals of the system, namely the rendering systems available, management of saved configurations, logging, and access to other classes in the system. Acts as a hub from which all other objects may be reached. An instance of Root must be created before any other Ogre operations are called. Once an instance has been created, the same instance is accessible throughout the life of that object by using Root::getSingleton (as a reference) or Root::getSingletonPtr (as a pointer).

## Constructor & Destructor Documentation

Ogre::Root::Root | ( | const String & | pluginFileName = `"plugins.cfg"`,
|  | const String & | configFileName = `"ogre.cfg"`,
|  | const String & | logFileName = `"Ogre.log"` |
| ) |  |  |

  | configFileName | The file that contains the configuration to be loaded. Defaults to "ogre.cfg", may be left blank to load nothing.
  | logFileName | The logfile to create, defaults to Ogre.log, may be left blank if you've already set up LogManager & Log yourself

Ogre::Root::~Root | ( |  | ) |

## Member Function Documentation

void Ogre::Root::loadPlugins | ( | const String & | pluginsfile = `"plugins.cfg"` | ) | `[protected]`

Method reads a plugins configuration file and instantiates all plugins.

Parameters:

  | pluginsfile | The file that contains plugins information. Defaults to "plugins.cfg".

void Ogre::Root::initialisePlugins | ( |  | ) | `[protected]`

Initialise all loaded plugins - allows plugins to perform actions once the renderer is initialised.

void Ogre::Root::shutdownPlugins | ( |  | ) | `[protected]`

Shuts down all loaded plugins - allows things to be tidied up whilst all plugins are still loaded.

void Ogre::Root::unloadPlugins | ( |  | ) | `[protected]`

Unloads all loaded plugins.

void Ogre::Root::oneTimePostWindowInit | ( | void |  | ) | `[protected]`

Real Ogre::Root::calculateEventTime | ( | unsigned long | now,
|  | FrameEventTimeType | type |
| ) |  |  | `[protected]`

Internal method for calculating the average time between recently fired events.

Parameters:

  | now | The current time in ms.
  | type | The type of event to be considered.

void Ogre::Root::saveConfig | ( | void |  | ) |

Saves the details of the current configuration.

Remarks:
  Stores details of the current configuration so it may be restored later on.

bool Ogre::Root::restoreConfig | ( | void |  | ) |

Checks for saved video/sound/etc settings.

Remarks:
  This method checks to see if there is a valid saved configuration from a previous run. If there is, the state of the system will be restored to that configuration.

Returns:
  If a valid configuration was found, true is returned.

  If there is no saved configuration, or if the system failed with the last config settings, false is returned.

bool Ogre::Root::showConfigDialog | ( | void |  | ) |

Displays a dialog asking the user to choose system settings.

Remarks:
  This method displays the default dialog allowing the user to choose the renderering system, video mode etc. If there is are any settings saved already, they will be restored automatically before displaying the dialogue. When the user accepts a group of settings, this will automatically call Root::setRenderSystem, RenderSystem::setConfigOption and Root::saveConfig with the user's choices. This is the easiest way to get the system configured.

Returns:
  If the user clicked 'Ok', true is returned.

  If they clicked 'Cancel' (in which case the app should strongly consider terminating), false is returned.

void Ogre::Root::addRenderSystem | ( | RenderSystem * | newRend | ) |

Adds a new rendering subsystem to the list of available renderers.

Remarks:
  Intended for use by advanced users and plugin writers only! Calling this method with a pointer to a valid RenderSystem (sublcass) adds a rendering API implementation to the list of available ones. Typical examples would be an OpenGL implementation and a Direct3D implementation.

Note:
  This should usually be called from the dllStartPlugin() function of an extension plug-in.

RenderSystemList* Ogre::Root::getAvailableRenderers | ( | void |  | ) |

Retrieve a list of the available render systems.

Remarks:
  Retrieves a pointer to the list of available renderers as a list of RenderSystem subclasses. Can be used to build a custom settings dialog.

RenderSystem* Ogre::Root::getRenderSystemByName | ( | const String & | name | ) |

Retrieve a pointer to the render system by the given name.

Parameters:

  | name | Name of the render system intend to retrieve.

Returns:
  A pointer to the render system, NULL if no found.

void Ogre::Root::setRenderSystem | ( | RenderSystem * | system | ) |

Sets the rendering subsystem to be used.

Remarks:
  This method indicates to OGRE which rendering system is to be used (e.g. Direct3D, OpenGL etc). This is called automatically by the default config dialog, and when settings are restored from a previous configuraion. If used manually it could be used to set the renderer from a custom settings dialog. Once this has been done, the renderer can be initialised using Root::initialise.

  This method is also called by render systems if they are initialised directly.

Parameters:

  | system | Pointer to the render system to use.

See also:
  RenderSystem

RenderSystem* Ogre::Root::getRenderSystem | ( | void |  | ) |

Retrieve a pointer to the currently selected render system.

RenderWindow* Ogre::Root::initialise | ( | bool | autoCreateWindow,
|  | const String & | windowTitle = `"OGRE Render Window"` |
| ) |  |  |

Initialises the renderer.

Remarks:
  This method can only be called after a renderer has been selected with Root::setRenderSystem, and it will initialise the selected rendering system ready for use.

Parameters:

  | autoCreateWindow | If true, a rendering window will automatically be created (saving a call to RenderSystem::createRenderWindow). The window will be created based on the options currently set on the render system.

Returns:
  A pointer to the automatically created window, if requested, otherwise NULL.

bool Ogre::Root::isInitialised | ( | void |  | ) | const

Returns whether the system is initialised or not.

Definition at line 296 of file OgreRoot.h.

void Ogre::Root::addSceneManagerFactory | ( | SceneManagerFactory * | fact | ) |

Register a new SceneManagerFactory, a factory object for creating instances of specific SceneManagers.

Remarks:
  Plugins should call this to register as new SceneManager providers.

void Ogre::Root::removeSceneManagerFactory | ( | SceneManagerFactory * | fact | ) |

Unregister a SceneManagerFactory.

const SceneManagerMetaData* Ogre::Root::getSceneManagerMetaData | ( | const String & | typeName | ) | const

Get more information about a given type of SceneManager.

Remarks:
  The metadata returned tells you a few things about a given type of SceneManager, which can be created using a factory that has been registered already.

Parameters:

  | typeName | The type name of the SceneManager you want to enquire on. If you don't know the typeName already, you can iterate over the metadata for all types using getMetaDataIterator.

SceneManagerEnumerator::MetaDataIterator Ogre::Root::getSceneManagerMetaDataIterator | ( | void |  | ) | const

Iterate over all types of SceneManager available for construction, providing some information about each one.

SceneManager* Ogre::Root::createSceneManager | ( | const String & | typeName,
|  | const String & | instanceName = `StringUtil::BLANK` |
| ) |  |  |

Create a SceneManager instance of a given type.

Remarks:
  You can use this method to create a SceneManager instance of a given specific type. You may know this type already, or you may have discovered it by looking at the results from getMetaDataIterator.

Note:
  This method throws an exception if the named type is not found.

Parameters:

  | typeName | String identifying a unique SceneManager type
  | instanceName | Optional name to given the new instance that is created. If you leave this blank, an auto name will be assigned.

SceneManager* Ogre::Root::createSceneManager | ( | SceneTypeMask | typeMask,
|  | const String & | instanceName = `StringUtil::BLANK` |
| ) |  |  |

Create a SceneManager instance based on scene type support.

Remarks:
  Creates an instance of a SceneManager which supports the scene types identified in the parameter. If more than one type of SceneManager has been registered as handling that combination of scene types, in instance of the last one registered is returned.

Note:
  This method always succeeds, if a specific scene manager is not found, the default implementation is always returned.

Parameters:

  | typeMask | A mask containing one or more SceneType flags
  | instanceName | Optional name to given the new instance that is created. If you leave this blank, an auto name will be assigned.

void Ogre::Root::destroySceneManager | ( | SceneManager * | sm | ) |

Destroy an instance of a SceneManager.

SceneManager* Ogre::Root::getSceneManager | ( | const String & | instanceName | ) | const

Get an existing SceneManager instance that has already been created, identified by the instance name.

Parameters:

  | instanceName | The name of the instance to retrieve.

SceneManagerEnumerator::SceneManagerIterator Ogre::Root::getSceneManagerIterator | ( | void |  | ) |

Get an iterator over all the existing SceneManager instances.

TextureManager* Ogre::Root::getTextureManager | ( | void |  | ) |

Retrieves a reference to the current TextureManager.

Remarks:
  This performs the same function as TextureManager::getSingleton, but is provided for convenience particularly to scripting engines.

  Note that a TextureManager will NOT be available until the Ogre system has been initialised by selecting a RenderSystem, calling Root::initialise and a window having been created (this may have been done by initialise if required). This is because the exact runtime subclass which will be implementing the calls will differ depending on the rendering engine selected, and these typically require a window upon which to base texture format decisions.

MeshManager* Ogre::Root::getMeshManager | ( | void |  | ) |

Retrieves a reference to the current MeshManager.

Remarks:
  This performs the same function as MeshManager::getSingleton and is provided for convenience to scripting engines.

String Ogre::Root::getErrorDescription | ( | long | errorNumber | ) |

Utility function for getting a better description of an error code.

void Ogre::Root::addFrameListener | ( | FrameListener * | newListener | ) |

Registers a FrameListener which will be called back every frame.

Remarks:
  A FrameListener is a class which implements methods which will be called every frame.

  See the FrameListener class for more details on the specifics It is imperitive that the instance passed to this method is not destroyed before either the rendering loop ends, or the class is removed from the listening list using removeFrameListener.

Note:
  This method can only be called after Root::initialise has been called.

See also:
  FrameListener, Root::removeFrameListener

void Ogre::Root::removeFrameListener | ( | FrameListener * | oldListener | ) |

Removes a FrameListener from the list of listening classes.

See also:
  FrameListener, Root::addFrameListener

void Ogre::Root::queueEndRendering | ( | void |  | ) |

Queues the end of rendering.

Remarks:
  This method will do nothing unless startRendering() has been called, in which case before the next frame is rendered the rendering loop will bail out.

See also:
  Root, Root::startRendering

void Ogre::Root::startRendering | ( | void |  | ) |

Starts / restarts the automatic rendering cycle.

Remarks:
  This method begins the automatic rendering of the scene. It will NOT return until the rendering cycle is halted.

  During rendering, any FrameListener classes registered using addFrameListener will be called back for each frame that is to be rendered, These classes can tell OGRE to halt the rendering if required, which will cause this method to return.

Note:
  Users of the OGRE library do not have to use this automatic rendering loop. It is there as a convenience and is most useful for high frame rate applications e.g. games. For applications that don't need to constantly refresh the rendering targets (e.g. an editor utility), it is better to manually refresh each render target only when required by calling RenderTarget::update, or if you want to run your own render loop you can update all targets on demand using Root::renderOneFrame.

  This frees up the CPU to do other things in between refreshes, since in this case frame rate is less important.

  This method can only be called after Root::initialise has been called.

bool Ogre::Root::renderOneFrame | ( | void |  | ) |

Render one frame.

Remarks:
  Updates all the render targets automatically and then returns, raising frame events before and after.

void Ogre::Root::shutdown | ( | void |  | ) |

Shuts down the system manually.

Remarks:
  This is normally done by Ogre automatically so don't think you have to call this yourself. However this is here for convenience, especially for dealing with unexpected errors or for systems which need to shut down Ogre on demand.

void Ogre::Root::addResourceLocation | ( | const String & | name,
|  | const String & | locType,
|  | const String & | groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`,
|  | bool | recursive = `false` |
| ) |  |  |

Adds a location to the list of searchable locations for a Resource type.

Remarks:
  Resource files (textures, models etc) need to be loaded from specific locations. By calling this method, you add another search location to the list. Locations added first are preferred over locations added later.

  Locations can be folders, compressed archives, even perhaps remote locations. Facilities for loading from different locations are provided by plugins which provide implementations of the Archive class. All the application user has to do is specify a 'loctype' string in order to indicate the type of location, which should map onto one of the provided plugins. Ogre comes configured with the 'FileSystem' (folders) and 'Zip' (archive compressed with the pkzip / WinZip etc utilities) types.

  You can also supply the name of a resource group which should have this location applied to it. The ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME group is the default, and one resource group which will always exist. You should consider defining resource groups for your more specific resources (e.g. per level) so that you can control loading / unloading better.

Parameters:

  | name | The name of the location, e.g. './data' or '/compressed/gamedata.zip'
  | locType | A string identifying the location type, e.g. 'FileSystem' (for folders), 'Zip' etc. Must map to a registered plugin which deals with this type (FileSystem and Zip should always be available)
  | groupName | Type of name of the resource group which this location should apply to; defaults to the General group which applies to all non-specific resources.
  | recursive | If the resource location has a concept of recursive directory traversal, enabling this option will mean you can load resources in subdirectories using only their unqualified name. The default is to disable this so that resources in subdirectories with the same name are still unique.

See also:
  Archive

void Ogre::Root::removeResourceLocation | ( | const String & | name,
|  | const String & | groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME` |
| ) |  |  |

Removes a resource location from the list.

See also:
  addResourceLocation

Parameters:

  | name | The name of the resource location as specified in addResourceLocation
  | groupName | The name of the resource group to which this location was assigned.

void Ogre::Root::convertColourValue | ( | const ColourValue & | colour,
|  | uint32 * | pDest |
| ) |  |  |

Generates a packed data version of the passed in ColourValue suitable for use with the current RenderSystem.

Remarks:
  Since different render systems have different colour data formats (eg RGBA for GL, ARGB for D3D) this method allows you to use 1 method for all.

Parameters:

  | colour | The colour to convert
  | pDest | Pointer to location to put the result.

RenderWindow* Ogre::Root::getAutoCreatedWindow | ( | void |  | ) |

Retrieves a pointer to the window that was created automatically.

Remarks:
  When Root is initialised an optional window is created. This method retreives a pointer to that window.

Note:
  returns a null pointer when Root has not been initialised with the option of creating a window.

RenderWindow* Ogre::Root::createRenderWindow | ( | const String & | name,
|  | unsigned int | width,
|  | unsigned int | height,
|  | bool | fullScreen,
|  | const NameValuePairList * | miscParams = `0` |
| ) |  |  |

Creates a new rendering window.

Remarks:
  This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

  After creation, this window can be retrieved using getRenderTarget().

Parameters:

  | name | The name of the window. Used in other methods later like setRenderTarget and getRenderWindow.
  | width | The width of the new window.
  | height | The height of the new window.
  | fullScreen | Specify true to make the window full screen without borders, title bar or menu bar.
  | miscParams | A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platorms unless indicated otherwise:

Key: "title" Description: The title of the window that will appear in the title bar Values: string Default: RenderTarget name

Key: "colourDepth" Description: Colour depth of the resulting rendering window; only applies if fullScreen is set. Values: 16 or 32 Default: desktop depth Notes: [W32 specific]

Key: "left" Description: screen x coordinate from left Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen

Key: "top" Description: screen y coordinate from top Values: positive integers Default: 'center window on screen' Notes: Ignored in case of full screen

Key: "depthBuffer" [DX9 specific] Description: Use depth buffer Values: false or true Default: true

Key: "externalWindowHandle" [API specific] Description: External window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) for GLX Default: 0 (None)

Key: "externalGLControl" [Win32 OpenGL specific] Description: Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls. The Ogre OpenGL context can be retrieved after Ogre initialisation by calling wglGetCurrentDC() and wglGetCurrentContext(). It is only used when the externalWindowHandle parameter is used. Values: true, false Default: false

Key: "externalGLContext" [Win32 OpenGL specific] Description: Use an externally created GL context Values: <Context as="" unsigned="" long>=""> Default: 0 (create own context)

Key: "parentWindowHandle" [API specific] Description: Parent window handle, for embedding the OGRE context Values: positive integer for W32 (HWND handle) poslong:posint:poslong for GLX (display*:screen:windowHandle) Default: 0 (None)

Key: "FSAA" Description: Full screen antialiasing factor Values: 0,2,4,6,... Default: 0

Key: "displayFrequency" Description: Display frequency rate, for fullscreen mode Values: 60...? Default: Desktop vsync rate

Key: "vsync" Description: Synchronize buffer swaps to vsync Values: true, false Default: 0

Key: "border" Description: The type of window border (in windowed mode) Values: none, fixed, resize Default: resize

Key: "outerDimensions" Description: Whether the width/height is expressed as the size of the outer window, rather than the content area Values: true, false Default: false

Key: "useNVPerfHUD" [DX9 specific] Description: Enable the use of nVidia NVPerfHUD Values: true, false Default: false

void Ogre::Root::detachRenderTarget | ( | RenderTarget * | pWin | ) |

Destroys a rendering window.

void Ogre::Root::detachRenderTarget | ( | const String & | name | ) |

Destroys a named rendering window.

RenderTarget* Ogre::Root::getRenderTarget | ( | const String & | name | ) |

Retrieves a pointer to the a named render window.

void Ogre::Root::loadPlugin | ( | const String & | pluginName | ) |

Manually load a Plugin contained in a DLL / DSO.

Remarks:
  Plugins embedded in DLLs can be loaded at startup using the plugin configuration file specified when you create Root (default: plugins.cfg). This method allows you to load plugin DLLs directly in code. The DLL in question is expected to implement a dllStartPlugin method which instantiates a Plugin subclass and calls Root::installPlugin. It should also implement dllStopPlugin (see Root::unloadPlugin)

Parameters:

  | pluginName | Name of the plugin library to load

void Ogre::Root::unloadPlugin | ( | const String & | pluginName | ) |

Manually unloads a Plugin contained in a DLL / DSO.

Remarks:
  Plugin DLLs are unloaded at shutdown automatically. This method allows you to unload plugins in code, but make sure their dependencies are decoupled first. This method will call the dllStopPlugin method defined in the DLL, which in turn should call Root::uninstallPlugin.

Parameters:

  | pluginName | Name of the plugin library to unload

void Ogre::Root::installPlugin | ( | Plugin * | plugin | ) |

Install a new plugin.

Remarks:
  This installs a new extension to OGRE. The plugin itself may be loaded from a DLL / DSO, or it might be statically linked into your own application. Either way, something has to call this method to get it registered and functioning. You should only call this method directly if your plugin is not in a DLL that could otherwise be loaded with loadPlugin, since the DLL function dllStartPlugin should call this method when the DLL is loaded.

void Ogre::Root::uninstallPlugin | ( | Plugin * | plugin | ) |

Uninstall an existing plugin.

Remarks:
  This uninstalls an extension to OGRE. Plugins are automatically uninstalled at shutdown but this lets you remove them early. If the plugin was loaded from a DLL / DSO you should call unloadPlugin which should result in this method getting called anyway (if the DLL is well behaved).

const PluginInstanceList& Ogre::Root::getInstalledPlugins | ( |  | ) | const

Gets a read-only list of the currently installed plugins.

Definition at line 615 of file OgreRoot.h.

Timer* Ogre::Root::getTimer | ( | void |  | ) |

Gets a pointer to the central timer used for all OGRE timings.

bool Ogre::Root::_fireFrameStarted | ( | FrameEvent & | evt | ) |

Method for raising frame started events.

Remarks:
  This method is only for internal use when you use OGRE's inbuilt rendering loop (Root::startRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameListener objects are notified of frame events; processes like texture animation and particle systems rely on this.

  Calling this method also increments the frame number, which is important for keeping some elements of the engine up to date.

Note:
  This method takes an event object as a parameter, so you can specify the times yourself. If you are happy for OGRE to automatically calculate the frame time for you, then call the other version of this method with no parameters.

Parameters:

  | evt | Event object which includes all the timing information which you have calculated for yourself

Returns:
  False if one or more frame listeners elected that the rendering loop should be terminated, true otherwise.

bool Ogre::Root::_fireFrameEnded | ( | FrameEvent & | evt | ) |

Method for raising frame ended events.

Remarks:
  This method is only for internal use when you use OGRE's inbuilt rendering loop (Root::startRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameListener objects are notified of frame events; processes like texture animation and particle systems rely on this.

Note:
  This method takes an event object as a parameter, so you can specify the times yourself. If you are happy for OGRE to automatically calculate the frame time for you, then call the other version of this method with no parameters.

Parameters:

  | evt | Event object which includes all the timing information which you have calculated for yourself

Returns:
  False if one or more frame listeners elected that the rendering loop should be terminated, true otherwise.

bool Ogre::Root::_fireFrameStarted | ( |  | ) |

Method for raising frame started events.

Remarks:
  This method is only for internal use when you use OGRE's inbuilt rendering loop (Root::startRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameListener objects are notified of frame events; processes like texture animation and particle systems rely on this.

  Calling this method also increments the frame number, which is important for keeping some elements of the engine up to date.

Note:
  This method calculates the frame timing information for you based on the elapsed time. If you want to specify elapsed times yourself you should call the other version of this method which takes event details as a parameter.

Returns:
  False if one or more frame listeners elected that the rendering loop should be terminated, true otherwise.

bool Ogre::Root::_fireFrameEnded | ( |  | ) |

Method for raising frame ended events.

Remarks:
  This method is only for internal use when you use OGRE's inbuilt rendering loop (Root::startRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameListener objects are notified of frame events; processes like texture animation and particle systems rely on this.

Note:
  This method calculates the frame timing information for you based on the elapsed time. If you want to specify elapsed times yourself you should call the other version of this method which takes event details as a parameter.

Returns:
  False if one or more frame listeners elected that the rendering loop should be terminated, true otherwise.

unsigned long Ogre::Root::getCurrentFrameNumber | ( | void |  | ) | const

Gets the number of the current frame.

Definition at line 692 of file OgreRoot.h.

SceneManager* Ogre::Root::_getCurrentSceneManager | ( | void |  | ) | const

Returns the scene manager currently being used to render a frame.

Remarks:
  This is only intended for internal use; it is only valid during the rendering of a frame.

Definition at line 699 of file OgreRoot.h.

void Ogre::Root::_setCurrentSceneManager | ( | SceneManager * | sm | ) |

Sets the scene manager currently being used to render a frame.

Remarks:
  This is only intended for internal use.

void Ogre::Root::_updateAllRenderTargets | ( | void |  | ) |

Internal method used for updating all RenderTarget objects (windows, renderable textures etc) which are set to auto-update.

Remarks:
  You don't need to use this method if you're using Ogre's own internal rendering loop (Root::startRendering). If you're running your own loop you may wish to call it to update all the render targets which are set to auto update (RenderTarget::setAutoUpdated). You can also update individual RenderTarget instances using their own update() method.

RenderQueueInvocationSequence* Ogre::Root::createRenderQueueInvocationSequence | ( | const String & | name | ) |

Create a new RenderQueueInvocationSequence, useful for linking to Viewport instances to perform custom rendering.

Parameters:

  | name | The name to give the new sequence

RenderQueueInvocationSequence* Ogre::Root::getRenderQueueInvocationSequence | ( | const String & | name | ) |

Get a RenderQueueInvocationSequence.

Parameters:

  | name | The name to identify the sequence

void Ogre::Root::destroyRenderQueueInvocationSequence | ( | const String & | name | ) |

Destroy a RenderQueueInvocationSequence.

Remarks:
  You must ensure that no Viewports are using this sequence.

Parameters:

  | name | The name to identify the sequence

void Ogre::Root::destroyAllRenderQueueInvocationSequences | ( | void |  | ) |

Destroy all RenderQueueInvocationSequences.

Remarks:
  You must ensure that no Viewports are using custom sequences.

Parameters:

  | name | The name to identify the sequence

static Root& Ogre::Root::getSingleton | ( | void |  | ) | `[static]`

Override standard Singleton retrieval.

Remarks:
  Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

  This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from Ogre::Singleton< T >.

static Root* Ogre::Root::getSingletonPtr | ( | void |  | ) | `[static]`

Override standard Singleton retrieval.

Remarks:
  Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

Reimplemented from Ogre::Singleton< T >.

void Ogre::Root::clearEventTimes | ( | void |  | ) |

Clears the history of all event times.

Remarks:
  OGRE stores a history of the last few event times in order to smooth out any inaccuracies and temporary fluctuations. However, if you pause or don't render for a little while this can cause a lurch, so if you're resuming rendering after a break, call this method to reset the stored times

void Ogre::Root::setFrameSmoothingPeriod | ( | Real | period | ) |

Sets the period over which OGRE smooths out fluctuations in frame times.

Remarks:
  OGRE by default gives you the raw frame time, but can optionally smooths it out over several frames, in order to reduce the noticeable effect of occasional hiccups in framerate. These smoothed values are passed back as parameters to FrameListener calls.

  This method allow you to tweak the smoothing period, and is expressed in seconds. Setting it to 0 will result in completely unsmoothed frame times (the default).

Definition at line 800 of file OgreRoot.h.

Real Ogre::Root::getFrameSmoothingPeriod | ( | void |  | ) | const

Gets the period over which OGRE smooths out fluctuations in frame times.

Definition at line 802 of file OgreRoot.h.

void Ogre::Root::addMovableObjectFactory | ( | MovableObjectFactory * | fact,
|  | bool | overrideExisting = `false` |
| ) |  |  |

Register a new MovableObjectFactory which will create new MovableObject instances of a particular type, as identified by the getType() method.

Remarks:
  Plugin creators can create subclasses of MovableObjectFactory which construct custom subclasses of MovableObject for insertion in the scene. This is the primary way that plugins can make custom objects available.

Parameters:

  | fact | Pointer to the factory instance
  | overrideExisting | Set this to true to override any existing factories which are registered for the same type. You should only change this if you are very sure you know what you're doing.

void Ogre::Root::removeMovableObjectFactory | ( | MovableObjectFactory * | fact | ) |

Removes a previously registered MovableObjectFactory.

Remarks:
  All instances of objects created by this factory will be destroyed before removing the factory (by calling back the factories 'destroyInstance' method). The plugin writer is responsible for actually destroying the factory.

bool Ogre::Root::hasMovableObjectFactory | ( | const String & | typeName | ) | const

Checks whether a factory is registered for a given MovableObject type.

MovableObjectFactory* Ogre::Root::getMovableObjectFactory | ( | const String & | typeName | ) |

Get a MovableObjectFactory for the given type.

uint32 Ogre::Root::_allocateNextMovableObjectTypeFlag | ( | void |  | ) |

Allocate the next MovableObject type flag.

Remarks:
  This is done automatically if MovableObjectFactory::requestTypeFlags returns true; don't call this manually unless you're sure you need to.

MovableObjectFactoryIterator Ogre::Root::getMovableObjectFactoryIterator | ( | void |  | ) | const

Return an iterator over all the MovableObjectFactory instances currently registered.
