Detailed Description

Adds inverse kinematics for a single joint of an animated mesh to point towards a target.

This can be used to make a creature look at something or to aim at a target. The component has to be attached to a child object of an animated mesh. The animated mesh needs to be driven by another component that generates an animation pose, such as a ezAnimationControllerComponent or a ezSimpleAnimationComponent. On those "EnableIK" must be set, then they will forward the pose to all their child objects and give them the opportunity to override the pose using IK.

Member Function Documentation

◆ DeserializeComponent()

void ezAimIKComponent::DeserializeComponent ( ezWorldReader & 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 ezComponent.

◆ SerializeComponent()

void ezAimIKComponent::SerializeComponent ( ezWorldWriter & inout_stream ) const

overridevirtual

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

Reimplemented from ezComponent.
