UMockRootMotionComponent

This component acts as the Driver for the [FMockRootMotionSimulation](API\Plugins\NetworkPredictionExtras\FMockRootMotionSimulation) It is essentially a standin for the movement component, and would be replaced by "new movement system" component.

This component acts as the Driver for the FMockRootMotionSimulation It is essentially a standin for the movement component, and would be replaced by "new movement system" component. If we support "root motion without movement component" then this could either be that component, or possibly built into or inherit from a USkeletalMeshComponent.

The main thing this provides is: -Interface for initiating root motions through the NP system (via client Input and via server "OOB" writes) -FinalizeFrame: take the output of the NP simulation and push it to the movement/animation components -Place holder implementation of IRootMotionSourceStore(the temp thing that maps our RootMotionSourceIDs -> actual sources)
