unsigned short  handle,
Skeleton creator 
)

Constructor, not to be used directly (use Bone::createChild or Skeleton::createBone)

Member Function Documentation

◆ createChild() [1/3]

Bone* Ogre::Bone::createChild ( unsigned short  handle,
const Vector3 translate = Vector3::ZERO,
const Quaternion rotate = Quaternion::IDENTITY 
)

Creates a new Bone as a child of this bone.

Remarks
This method creates a new bone which will inherit the transforms of this bone, with the handle specified.
Parameters
handleThe numeric handle to give the new bone; must be unique within the Skeleton.
translateInitial translation offset of child relative to parent
rotateInitial rotation relative to parent

◆ getHandle()

unsigned short Ogre::Bone::getHandle ( void  ) const

Gets the numeric handle for this bone (unique within the skeleton).

◆ setBindingPose()

void Ogre::Bone::setBindingPose ( void  )

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

◆ reset()

void Ogre::Bone::reset ( void  )

Resets the position and orientation of this Bone to the original binding position.

Remarks
Bones are bound to the mesh in a binding pose. They are then modified from this position during animation. This method returns the bone to it's original position and orientation.

◆ setManuallyControlled()

void Ogre::Bone::setManuallyControlled ( bool  manuallyControlled)

Sets whether or not this bone is manually controlled.

Remarks
Manually controlled bones can be altered by the application at runtime, and their positions will not be reset by the animation routines. Note that you should also make sure that there are no AnimationTrack objects referencing this bone, or if there are, you should disable them using pAnimation->destroyTrack(pBone->getHandle());
You can also use AnimationState::setBlendMask to mask out animation from chosen tracks if you want to prevent application of a scripted animation to a bone without altering the Animation definition.

◆ isManuallyControlled()

bool Ogre::Bone::isManuallyControlled ( ) const

Getter for mManuallyControlled Flag.

◆ _getOffsetTransform()

void Ogre::Bone::_getOffsetTransform ( Affine3 m) const

Gets the transform which takes bone space to current from the binding pose.

Remarks
Internal use only.

◆ _getBindingPoseInverseScale()

const Vector3& Ogre::Bone::_getBindingPoseInverseScale ( void  ) const
inline

Gets the inverted binding pose scale.

◆ _getBindingPoseInversePosition()

const Vector3& Ogre::Bone::_getBindingPoseInversePosition ( void  ) const
inline

Gets the inverted binding pose position.

◆ _getBindingPoseInverseOrientation()

See also
Node::needUpdate

Reimplemented from Ogre::Node.

Reimplemented in Ogre::TagPoint.

◆ getName()

◆ setOrientation() [1/2]

void Ogre::Node::setOrientation ( const Quaternion q)
inherited

Sets the orientation of this node via a quaternion.

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation). The default is to inherit as with other transforms.
Note that rotations are oriented around the node's origin.

◆ setOrientation() [2/2]

void Ogre::Node::setOrientation ( Real  w,
Real  x,
Real  y,
Real  z 
)
inherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ resetOrientation()

void Ogre::Node::resetOrientation ( void  )
inherited

Resets the nodes orientation (local axes as world axes, no rotation).

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation). The default is to inherit as with other transforms.
Note that rotations are oriented around the node's origin.

◆ setPosition() [1/2]

void Ogre::Node::setPosition ( const Vector3 pos)
inherited

inlineinherited

Gets the position of the node relative to it's parent.

◆ setScale() [1/2]

void Ogre::Node::setScale ( const Vector3 scale)
inherited

Sets the scaling factor applied to this node.

Remarks
Scaling factors, unlike other transforms, are not always inherited by child nodes. Whether or not scalings affect the size of the child nodes depends on the setInheritScale option of the child. In some cases you want a scaling factor of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative size based on the parent's size), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own size). The default is to inherit as with other transforms.
Note that like rotations, scalings are oriented around the node's origin.

◆ setScale() [2/2]

void Ogre::Node::setScale ( Real  x,
Real  y,
Real  z 
)
inherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

inlineinherited

Gets the scaling factor of this node.

◆ setInheritOrientation()

void Ogre::Node::setInheritOrientation ( bool  inherit)
inherited

Tells the node whether it should inherit orientation from it's parent node.

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation). The default is to inherit as with other transforms.

inheritIf true, this node's orientation will be affected by its parent's orientation. If false, it will not be affected.

◆ getInheritOrientation()

bool Ogre::Node::getInheritOrientation ( void  ) const
inlineinherited

Returns true if this node is affected by orientation applied to the parent node.

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation). The default is to inherit as with other transforms.
See setInheritOrientation for more info.

◆ setInheritScale()

void Ogre::Node::setInheritScale ( bool  inherit)
inherited

Tells the node whether it should inherit scaling factors from it's parent node.

Remarks
Scaling factors, unlike other transforms, are not always inherited by child nodes. Whether or not scalings affect the size of the child nodes depends on the setInheritScale option of the child. In some cases you want a scaling factor of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative size based on the parent's size), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own size). The default is to inherit as with other transforms.
Parameters
inheritIf true, this node's scale will be affected by its parent's scale. If false, it will not be affected.

◆ getInheritScale()

bool Ogre::Node::getInheritScale ( void  ) const
inlineinherited

Returns true if this node is affected by scaling factors applied to the parent node.

Remarks
See setInheritScale for more info.

References Ogre::Quaternion::IDENTITY.

◆ scale() [1/2]

void Ogre::Node::scale ( const Vector3 scale)
inherited

Scales the node, combining it's current scale with the passed in scaling factor.

Remarks
This method applies an extra scaling factor to the node's existing scale, (unlike setScale which overwrites it) combining it's current scale with the new one. E.g. calling this method twice with Vector3(2,2,2) would have the same effect as setScale(Vector3(4,4,4)) if the existing scale was 1.
Note that like rotations, scalings are oriented around the node's origin.

◆ scale() [2/2]

◆ translate() [3/4]

void Ogre::Node::translate ( const Matrix3 axes,
const Vector3 move,
TransformSpace  relativeTo = TS_PARENT 
)
inherited

Moves the node along arbitrary axes.

Remarks
This method translates the node by a vector which is relative to a custom set of axes.

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

Sets the current transform of this node to be the 'initial state' ie that position / orientation / scale to be used as a basis for delta values used in keyframe animation.

Remarks
You never need to call this method unless you plan to animate this node. If you do plan to animate it, call this method once you've loaded the node with it's base state, ie the state on which all keyframes are based.
If you never call this method, the initial state is the identity transform, ie do nothing.

◆ resetToInitialState()

void Ogre::Node::resetToInitialState ( void  )
inherited

Resets the position / orientation / scale of this node to it's initial state, see setInitialState for more info.

◆ getInitialPosition()

const Vector3& Ogre::Node::getInitialPosition ( void  ) const
inlineinherited

Gets the initial position of this node, see setInitialState for more info.

Remarks
Also resets the cumulative animation weight used for blending.

◆ convertWorldToLocalPosition()

Vector3 Ogre::Node::convertWorldToLocalPosition ( const Vector3 worldPos)
inherited

Gets the local position, relative to this node, of the given world-space position.

◆ convertLocalToWorldPosition()

Vector3 Ogre::Node::convertLocalToWorldPosition ( const Vector3 localPos)
inherited

Gets the world position of a point in the node local space useful for simple transforms that don't require a child node.

◆ convertWorldToLocalDirection()

Vector3 Ogre::Node::convertWorldToLocalDirection ( const Vector3 worldDir,
bool  useScale 
)
inherited

Gets the local direction, relative to this node, of the given world-space direction.

◆ convertLocalToWorldDirection()

Vector3 Ogre::Node::convertLocalToWorldDirection ( const Vector3 localDir,
bool  useScale 
)
inherited

Gets the world direction of a point in the node local space useful for simple transforms that don't require a child node.

◆ convertWorldToLocalOrientation()

Quaternion Ogre::Node::convertWorldToLocalOrientation ( const Quaternion worldOrientation)
inherited

Gets the local orientation, relative to this node, of the given world-space orientation.

◆ convertLocalToWorldOrientation()

Quaternion Ogre::Node::convertLocalToWorldOrientation ( const Quaternion localOrientation)
inherited

Gets the world orientation of an orientation in the node local space useful for simple transforms that don't require a child node.

◆ getInitialOrientation()

const Quaternion& Ogre::Node::getInitialOrientation ( void  ) const
inlineinherited

Gets the initial orientation of this node, see setInitialState for more info.

◆ getInitialScale()

const Vector3& Ogre::Node::getInitialScale ( void  ) const
inlineinherited

Gets the initial position of this node, see setInitialState for more info.

◆ getSquaredViewDepth()

Real Ogre::Node::getSquaredViewDepth ( const Camera cam) const
inherited

Helper function, get the squared view depth.

◆ requestUpdate()

void Ogre::Node::requestUpdate ( Node child,
bool  forceParentUpdate = false 
)
inherited

Called by children to notify their parent that they need an update.

Parameters
childThe child Node to be updated
forceParentUpdateEven if the node thinks it has already told it's parent, tell it anyway

◆ cancelUpdate()

void Ogre::Node::cancelUpdate ( Node child)
inherited

Called by children to notify their parent that they no longer need an update.

◆ getDebugRenderable()

DebugRenderable* Ogre::Node::getDebugRenderable ( Real  scaling)
inherited

Get a debug renderable for rendering the Node.

Referenced by Ogre::SceneNode::getAutoTrackLocalDirection().

◆ queueNeedUpdate()

static void Ogre::Node::queueNeedUpdate ( Node n)
staticinherited

Queue a 'needUpdate' call to a node safely.

Remarks
You can't call needUpdate() during the scene graph update, e.g. in response to a Node::Listener hook, because the graph is already being updated, and update flag changes cannot be made reliably in that context. Call this method if you need to queue a needUpdate call in this case.

◆ processQueuedUpdates()

static void Ogre::Node::processQueuedUpdates ( void  )
staticinherited

Process queued 'needUpdate' calls.

◆ setUserAny()

void Ogre::Node::setUserAny ( const Any anything)
inlineinherited
Deprecated:
use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this Node. This can be a pointer back to one of your own classes for instance.

◆ getUserAny()

const Any& Ogre::Node::getUserAny ( void  ) const
inlineinherited
Deprecated:
use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

◆ getUserObjectBindings() [1/2]

UserObjectBindings& Ogre::Node::getUserObjectBindings ( )
inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also
UserObjectBindings::setUserAny.

◆ getUserObjectBindings() [2/2]

const UserObjectBindings& Ogre::Node::getUserObjectBindings ( ) const
inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also
