# Offline Rigidbodies

While prediction is in use, if you have a rigidbody object in your game that is not synchronized with the network it must contain an OfflineRigidbody component. Please review the [OfflineRigidbody component page](https://fish-networking.gitbook.io/docs/fishnet-building-blocks/components/prediction/offlinerigidbody) for more information on it's uses.
