Remarks

MoverPhysicsLiaisonComponent: This component acts as a middleman between an actor's Mover component and the chaos physics network prediction system. This class is set on a Mover component as the "back end".

Variables

  Type Name Description
Protected variable bool bCachedInputIsValid  
Protected variable bool bCachedLastPhysicsSyncStateIsValid  
Protected variable bool bUsingAsyncPhysics  
Protected variable FMoverSyncState CachedLastPhysicsSyncState The cached physics state is the latest output from the physics thread This can be different from the cached sync state on the mover component which is interpolated to match the interpolated physics particle Note: Time is physics solver time
Protected variable double CachedLastPhysicsSyncStateOutputTime  
Protected variable TObjectPtr< UCommonLegacyMovementSettings > CommonMovementSettings  
Protected variable TUniquePtr< Chaos::FCharacterGroundConstraint > Constraint  
Protected variable TObjectPtr< UMoverComponent > MoverComp  
Protected variable FMoverInputCmdContext NetInputCmd These are written to by the network input and state data.
Protected variable FMoverSyncState NetSyncState  
Protected variable TObjectPtr< UNetworkPhysicsComponent > NetworkPhysicsComponent
