Syntax
struct IUpdate : public UE::AnimNext::ITraitInterface
Remarks
This interface is called during the update traversal.
When a node is visited, PreUpdate is first called on its top trait. It is responsible for forwarding the call to the next trait that implements this interface on the trait stack of the node. Once all traits have had the chance to PreUpdate, the children will then evaluate and PostUpdate will then be called afterwards on the original trait.
