.. _class_SceneTree_set_network_peer:

- void  **set_network_peer**  **(** :ref:`NetworkedMultiplayerPeer<class_networkedmultiplayerpeer>` peer  **)**

Set the peer object to handle the RPC system (effectively enabling networking). Depending on the peer itself, the SceneTree will become a network server (check with :ref:`is_network_server()<class_SceneTree_is_network_server()>`) and will set root node's network mode to master (see NETWORK_MODE\_\* constants in :ref:`Node<class_node>`), or it will become a regular peer with root node set to slave. All child nodes are set to inherit the network mode by default. Handling of networking-related events (connection, disconnection, new clients) is done by connecting to SceneTree's signals.
