## Detailed Description

A collection of Bone objects used to animate a skinned mesh.

Remarks:
  Skeletal animation works by having a collection of 'bones' which are actually just joints with a position and orientation, arranged in a tree structure. For example, the wrist joint is a child of the elbow joint, which in turn is a child of the shoulder joint. Rotating the shoulder automatically moves the elbow and wrist as well due to this hierarchy.

  So how does this animate a mesh? Well every vertex in a mesh is assigned to one or more bones which affects it's position when the bone is moved. If a vertex is assigned to more than one bone, then weights must be assigned to determine how much each bone affects the vertex (actually a weight of 1.0 is used for single bone assignments). Weighted vertex assignments are especially useful around the joints themselves to avoid 'pinching' of the mesh in this region.

  Therefore by moving the skeleton using preset animations, we can animate the mesh. The advantage of using skeletal animation is that you store less animation data, especially as vertex counts increase. In addition, you are able to blend multiple animations together (e.g. walking and looking around, running and shooting) and provide smooth transitions between animations without incurring as much of an overhead as would be involved if you did this on the core vertex data.

  Skeleton definitions are loaded from datafiles, namely the .skeleton file format. They are loaded on demand, especially when referenced by a Mesh.

## Constructor & Destructor Documentation

Ogre::Skeleton::Skeleton | ( |  | ) | `[protected]`

Internal constructor for use by SkeletonInstance only.

Ogre::Skeleton::Skeleton | ( | ResourceManager * | creator,
|  | const String & | name,
|  | ResourceHandle | handle,
|  | const String & | group,
|  | bool | isManual = `false`,
|  | ManualResourceLoader * | loader = `0` |
| ) |  |  |

Constructor, don't call directly, use SkeletonManager.

Remarks:
  On creation, a Skeleton has a no bones, you should create them and link them together appropriately.

virtual Ogre::Skeleton::~Skeleton | ( |  | ) | `[virtual]`

## Member Function Documentation

virtual Bone* Ogre::Skeleton::createBone | ( | void |  | ) | `[virtual]`

Creates a brand new Bone owned by this Skeleton.

Remarks:
  This method creates an unattached new Bone for this skeleton. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

  Note that this method automatically generates a handle for the bone, which you can retrieve using Bone::getHandle. If you wish the new Bone to have a specific handle, use the alternate form of this method which takes a handle as a parameter, although you should note the restrictions.

virtual Bone* Ogre::Skeleton::createBone | ( | unsigned short | handle | ) | `[virtual]`

Creates a brand new Bone owned by this Skeleton.

Remarks:
  This method creates an unattached new Bone for this skeleton and assigns it a specific handle. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created a root bone.

Parameters:

  | handle | The handle to give to this new bone - must be unique within this skeleton. You should also ensure that all bone handles are eventually contiguous (this is to simplify their compilation into an indexed array of transformation matrices). For this reason it is advised that you use the simpler createBone method which automatically assigns a sequential handle starting from 0.

virtual Bone* Ogre::Skeleton::createBone | ( | const String & | name | ) | `[virtual]`

Creates a brand new Bone owned by this Skeleton.

Remarks:
  This method creates an unattached new Bone for this skeleton and assigns it a specific name.Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

Parameters:

  | name | The name to give to this new bone - must be unique within this skeleton. Note that the way OGRE looks up bones is via a numeric handle, so if you name a Bone this way it will be given an automatic sequential handle. The name is just for your convenience, although it is recommended that you only use the handle to retrieve the bone in performance-critical code.

virtual Bone* Ogre::Skeleton::createBone | ( | const String & | name,
|  | unsigned short | handle |
| ) |  |  | `[virtual]`

Creates a brand new Bone owned by this Skeleton.

Remarks:
  This method creates an unattached new Bone for this skeleton and assigns it a specific name and handle. Unless this is to be a root bone (there may be more than one of these), you must attach it to another Bone in the skeleton using addChild for it to be any use. For this reason you will likely be better off creating child bones using the Bone::createChild method instead, once you have created the root bone.

Parameters:

  | name | The name to give to this new bone - must be unique within this skeleton.
  | handle | The handle to give to this new bone - must be unique within this skeleton.

virtual unsigned short Ogre::Skeleton::getNumBones | ( | void |  | ) | const`[virtual]`

Returns the number of bones in this skeleton.

virtual Bone* Ogre::Skeleton::getRootBone | ( | void |  | ) | const`[virtual]`

Gets the root bone of the skeleton: deprecated in favour of getRootBoneIterator.

Remarks:
  The system derives the root bone the first time you ask for it. The root bone is the only bone in the skeleton which has no parent. The system locates it by taking the first bone in the list and going up the bone tree until there are no more parents, and saves this top bone as the root. If you are building the skeleton manually using createBone then you must ensure there is only one bone which is not a child of another bone, otherwise your skeleton will not work properly. If you use createBone only once, and then use Bone::createChild from then on, then inherently the first bone you create will by default be the root.

virtual BoneIterator Ogre::Skeleton::getRootBoneIterator | ( | void |  | ) | `[virtual]`

Get an iterator over the root bones in the skeleton, ie those with no parents.

virtual BoneIterator Ogre::Skeleton::getBoneIterator | ( | void |  | ) | `[virtual]`

Get an iterator over all the bones in the skeleton.

virtual Bone* Ogre::Skeleton::getBone | ( | unsigned short | handle | ) | const`[virtual]`

Gets a bone by it's handle.

virtual Bone* Ogre::Skeleton::getBone | ( | const String & | name | ) | const`[virtual]`

Gets a bone by it's name.

virtual void Ogre::Skeleton::setBindingPose | ( | void |  | ) | `[virtual]`

Sets the current position / orientation to be the 'binding pose' ie the layout in which bones were originally bound to a mesh.

virtual void Ogre::Skeleton::reset | ( | bool | resetManualBones = `false` | ) | `[virtual]`

Resets the position and orientation of all bones in this skeleton to their original binding position.

Remarks:
  A skeleton is bound to a mesh in a binding pose. Bone positions are then modified from this position during animation. This method returns all the bones to their original position and orientation.

Parameters:

  | resetManualBones | If set to true, causes the state of manual bones to be reset too, which is normally not done to allow the manual state to persist even when keyframe animation is applied.

virtual Animation* Ogre::Skeleton::createAnimation | ( | const String & | name,
|  | Real | length |
| ) |  |  | `[virtual]`

Creates a new Animation object for animating this skeleton.

Parameters:

  | name | The name of this animation
  | length | The length of the animation in seconds

Reimplemented in Ogre::SkeletonInstance.

virtual Animation* Ogre::Skeleton::getAnimation | ( | const String & | name,
|  | const LinkedSkeletonAnimationSource ** | linker = `0` |
| ) |  |  | const`[virtual]`

Returns the named Animation object.

Remarks:
  Will pick up animations in linked skeletons (

See also:
  addLinkedSkeletonAnimationSource).

Parameters:

  | name | The name of the animation
  | linker | Optional pointer to a pointer to the linked skeleton animation where this is coming from.

Reimplemented in Ogre::SkeletonInstance.

virtual Animation* Ogre::Skeleton::_getAnimationImpl | ( | const String & | name,
|  | const LinkedSkeletonAnimationSource ** | linker = `0` |
| ) |  |  | const`[virtual]`

Internal accessor for animations (returns null if animation does not exist).

Reimplemented in Ogre::SkeletonInstance.

virtual bool Ogre::Skeleton::hasAnimation | ( | const String & | name | ) | `[virtual]`

Returns whether this skeleton contains the named animation.

virtual void Ogre::Skeleton::removeAnimation | ( | const String & | name | ) | `[virtual]`

Removes an Animation from this skeleton.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::setAnimationState | ( | const AnimationStateSet & | animSet | ) | `[virtual]`

Changes the state of the skeleton to reflect the application of the passed in collection of animations.

Remarks:
  Animating a skeleton involves both interpolating between keyframes of a specific animation, and blending between the animations themselves. Calling this method sets the state of the skeleton so that it reflects the combination of all the passed in animations, at the time index specified for each, using the weights specified. Note that the weights between animations do not have to sum to 1.0, because some animations may affect only subsets of the skeleton. If the weights exceed 1.0 for the same area of the skeleton, the movement will just be exaggerated.

Parameters:

virtual void Ogre::Skeleton::_initAnimationState | ( | AnimationStateSet * | animSet | ) | `[virtual]`

Initialise an animation set suitable for use with this skeleton.

Remarks:
  Only recommended for use inside the engine, not by applications.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::_getBoneMatrices | ( | Matrix4 * | pMatrices | ) | `[virtual]`

Populates the passed in array with the bone matrices based on the current position.

Remarks:

virtual unsigned short Ogre::Skeleton::getNumAnimations | ( | void |  | ) | const`[virtual]`

Gets the number of animations on this skeleton.

Reimplemented in Ogre::SkeletonInstance.

virtual Animation* Ogre::Skeleton::getAnimation | ( | unsigned short | index | ) | const`[virtual]`

Gets a single animation by index.

See also:
  addLinkedSkeletonAnimationSource).

Reimplemented in Ogre::SkeletonInstance.

Optimise all of this skeleton's animations.

See also:
  Animation::optimise

Parameters:

  | preservingIdentityNodeTracks | If true, don't destroy identity node tracks.

virtual void Ogre::Skeleton::addLinkedSkeletonAnimationSource | ( | const String & | skelName,
|  | Real | scale = `1.0f` |
| ) |  |  | `[virtual]`

Allows you to use the animations from another Skeleton object to animate this skeleton.

Remarks:
  If you have skeletons of identical structure (that means identically named bones with identical handles, and with the same hierarchy), but slightly different proportions or binding poses, you can re-use animations from one in the other. Because animations are actually stored as changes to bones from their bind positions, it's possible to use the same animation data for different skeletons, provided the skeletal structure matches and the 'deltas' stored in the keyframes apply equally well to the other skeletons bind position (so they must be roughly similar, but don't have to be identical). You can use the 'scale' option to adjust the translation and scale keyframes where there are large differences in size between the skeletons.

Note:
  This method takes a skeleton name, rather than a more specific animation name, for two reasons; firstly it allows some validation of compatibility of skeletal structure, and secondly skeletons are the unit of loading. Linking a skeleton to another in this way means that the linkee will be prevented from being destroyed until the linker is destroyed.

You cannot set up cyclic relationships, e.g. SkeletonA uses SkeletonB's animations, and SkeletonB uses SkeletonA's animations. This is because it would set up a circular dependency which would prevent proper unloading - make one of the skeletons the 'master' in this case.

Parameters:

  | skelName | Name of the skeleton to link animations from. This skeleton will be loaded immediately if this skeleton is already loaded, otherwise it will be loaded when this skeleton is.
  | scale | A scale factor to apply to translation and scaling elements of the keyframes in the other skeleton when applying the animations to this one. Compensates for skeleton size differences.

Reimplemented in Ogre::SkeletonInstance.

virtual void Ogre::Skeleton::removeAllLinkedSkeletonAnimationSources | ( | void |  | ) | `[virtual]`

Remove all links to other skeletons for the purposes of sharing animation.

Reimplemented in Ogre::SkeletonInstance.

virtual LinkedSkeletonAnimSourceIterator Ogre::Skeleton::getLinkedSkeletonAnimationSourceIterator | ( | void |  | ) | const`[virtual]`

virtual bool Ogre::Skeleton::getManualBonesDirty | ( | void |  | ) | const`[virtual]`

Have manual bones been modified since the skeleton was last updated?

Definition at line 340 of file OgreSkeleton.h.

virtual bool Ogre::Skeleton::hasManualBones | ( | void |  | ) | const`[virtual]`

Definition at line 342 of file OgreSkeleton.h.

virtual void Ogre::Skeleton::_mergeSkeletonAnimations | ( | const Skeleton * | source,
|  | const BoneHandleMap & | boneHandleMap,
|  | const StringVector & | animations = `StringVector()` |
| ) |  |  | `[virtual]`

Merge animations from another Skeleton object into this skeleton.

Remarks:
  This function allow merge two structures compatible skeletons. The 'compatible' here means identically bones will have same hierarchy, but skeletons are not necessary to have same number of bones (if number bones of source skeleton's more than this skeleton, they will copied as is, except that duplicate names are unallowed; and in the case of bones missing in source skeleton, nothing happen for those bones).

  There are also unnecessary to have same binding poses, this function will adjust keyframes of the source skeleton to match this skeleton automatically.

  It's useful for export skeleton animations seperately. i.e. export mesh and 'master' skeleton at the same time, and then other animations will export seperately (even if used completely difference binding pose), finally, merge seperately exported animations into 'master' skeleton.

Parameters:

  | source | Pointer to source skeleton. It'll keep unmodified.
  | boneHandleMap | A map to translate identically bone's handle from source skeleton to this skeleton. If mapped bone handle doesn't exists in this skeleton, it'll created. You can populate bone handle map manually, or use predefined functions build bone handle map for you. (

See also:
  _buildMapBoneByHandle, _buildMapBoneByName)

Parameters:

  Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Definition at line 149 of file OgreResource.h.

virtual void Ogre::Resource::postLoadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions after the load process, but before the resource has been marked as fully loaded.

Note:
  Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Reimplemented in Ogre::Mesh.

Definition at line 156 of file OgreResource.h.

virtual void Ogre::Resource::preUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions before the unload process.

Note:
  Mutex will have already been acquired by the unloading thread.

Definition at line 161 of file OgreResource.h.

virtual void Ogre::Resource::postUnloadImpl | ( | void |  | ) | `[protected, virtual, inherited]`

Internal hook to perform actions after the unload process, but before the resource has been marked as fully unloaded.

Note:
  Mutex will have already been acquired by the unloading thread.

Definition at line 166 of file OgreResource.h.

virtual void Ogre::Resource::queueFireBackgroundLoadingComplete | ( | void |  | ) | `[protected, virtual, inherited]`

Queue the firing of background loading complete event.

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) | `[virtual, inherited]`

Loads the resource, if it is not already.

Remarks:
  If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters:

  | backgroundThread | Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Resource::reload | ( | void |  | ) | `[virtual, inherited]`

Reloads the resource, if it is already loaded.

Remarks:
  Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

bool Ogre::Resource::isReloadable | ( | void |  | ) | const`[inherited]`

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 228 of file OgreResource.h.

bool Ogre::Resource::isManuallyLoaded | ( | void |  | ) | const`[inherited]`

Is this resource manually loaded?

Definition at line 235 of file OgreResource.h.

virtual void Ogre::Resource::unload | ( | void |  | ) | `[virtual, inherited]`

Unloads the resource; this is not permanent, the resource can be reloaded later if required.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::Resource::getSize | ( | void |  | ) | const`[inherited]`

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 247 of file OgreResource.h.

virtual void Ogre::Resource::touch | ( | void |  | ) | `[virtual, inherited]`

'Touches' the resource to indicate it has been used.

Reimplemented in Ogre::Material, and Ogre::UnifiedHighLevelGpuProgram.

Referenced by Ogre::Material::touch().

const String& Ogre::Resource::getName | ( | void |  | ) | const`[inherited]`

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

Definition at line 258 of file OgreResource.h.

ResourceHandle Ogre::Resource::getHandle | ( | void |  | ) | const`[inherited]`

Reimplemented in Ogre::SkeletonInstance.

Definition at line 263 of file OgreResource.h.

bool Ogre::Resource::isLoaded | ( | void |  | ) | const`[inherited]`

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 270 of file OgreResource.h.

LoadingState Ogre::Resource::isLoading | ( |  | ) | const`[inherited]`

Returns whether the resource is currently in the process of background loading.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 279 of file OgreResource.h.

LoadingState Ogre::Resource::getLoadingState | ( |  | ) | const`[inherited]`

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 286 of file OgreResource.h.

bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const`[inherited]`

Returns whether this Resource has been earmarked for background loading.

Remarks:
  This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 303 of file OgreResource.h.

void Ogre::Resource::setBackgroundLoaded | ( | bool | bl | ) | `[inherited]`

Tells the resource whether it is background loaded or not.

Remarks:

See also:
  Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 313 of file OgreResource.h.

void Ogre::Resource::escalateLoading | ( |  | ) | `[inherited]`

Escalates the loading of a background loaded resource.

Remarks:
  If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Resource::addListener | ( | Listener * | lis | ) | `[inherited]`

Register a listener on this resource.

See also:
  Resource::Listener

void Ogre::Resource::removeListener | ( | Listener * | lis | ) | `[inherited]`

Remove a listener on this resource.

See also:
  Resource::Listener

const String& Ogre::Resource::getGroup | ( | void |  | ) | `[inherited]`

Gets the group which this resource is a member of.

Reimplemented in Ogre::SkeletonInstance.

Definition at line 337 of file OgreResource.h.

void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) | `[inherited]`

Change the resource group ownership of a Resource.

Remarks:
  This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters:

  | newGroup | Name of the new group

ResourceManager* Ogre::Resource::getCreator | ( | void |  | ) | `[inherited]`

Gets the manager which created this resource.

Definition at line 349 of file OgreResource.h.

const String& Ogre::Resource::getOrigin | ( | void |  | ) | const`[inherited]`

Get the origin of this resource, e.g.

a script file name.

Remarks:
  This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

Definition at line 356 of file OgreResource.h.

void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) | `[inherited]`

Notify this resource of it's origin.

Definition at line 358 of file OgreResource.h.

virtual void Ogre::Resource::_fireBackgroundLoadingComplete | ( | void |  | ) | `[virtual, inherited]`

Firing of background loading complete event.

Remarks:
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

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.

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

Retrieves the parameter dictionary for this class.

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.

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

Definition at line 213 of file OgreStringInterface.h.

const ParameterList& Ogre::StringInterface::getParameters | ( | void |  | ) | const`[inherited]`

Retrieves a list of parameters valid for this object.

Returns:
  A reference to a static list of ParameterDef objects.

virtual bool Ogre::StringInterface::setParameter | ( | const String & | name,
|  | const String & | value |
| ) |  |  | `[virtual, inherited]`

Generic parameter setting method.

Remarks:
  Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | 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.

Returns:
  true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

virtual void Ogre::StringInterface::setParameterList | ( | const NameValuePairList & | paramList | ) | `[virtual, inherited]`

Generic multiple parameter setting method.

Remarks:
  Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

  | paramList | Name/value pair list

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

Definition at line 269 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

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, and Ogre::StringInterface::setParameter().

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.
