Detailed Description

Used to expose an animated mesh's bone as a game object, such that objects can be attached to it to move along.

The animation system deals with bone animations internally. Sometimes it is desirable to move certain objects along with a bone, for example when a character should hold something in their hand.

This component references a bone by name, and takes care to position the owner object at the same location as the bone whenever the animation pose changes. Thus it is possible to attach other objects as child objects to this one, so that they move along as well.

Member Function Documentation

◆ DeserializeComponent()

void plJointAttachmentComponent::DeserializeComponent ( plWorldReader & inout_stream)
overridevirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from plComponent.

◆ SerializeComponent()

void plJointAttachmentComponent::SerializeComponent ( plWorldWriter & inout_stream) const
overridevirtual

Override this to save the current state of the component to the given stream.

Reimplemented from plComponent.
