Detailed Description

A tagged point on a skeleton, which can be used to attach entities to on specific other entities.

Remarks:

A Skeleton, like a Mesh, is shared between Entity objects and simply updated as required when it comes to rendering. However there are times when you want to attach another object to an animated entity, and make sure that attachment follows the parent entity's animation (for example, a character holding a gun in his / her hand). This class simply identifies attachment points on a skeleton which can be used to attach child objects.

The child objects themselves are not physically attached to this class; as it's name suggests this class just 'tags' the area. The actual child objects are attached to the Entity using the skeleton which has this tag point. Use the Entity::attachMovableObjectToBone method to attach the objects, which creates a new TagPoint on demand.

const [virtual, inherited]

Returns a quaternion representing the nodes orientation.

virtual void Ogre::Node::setOrientation

(

const Quaternion &

q

)

[virtual, 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.
