What additional component is required along with a Network Proximity Checker on a game object?

A Network Identity component is essential for any game object that is intended to be networked within a Unity application. The purpose of the Network Identity is to uniquely identify the game object across the network. Therefore, when using a Network Proximity Checker, which functions to determine whether or not the player is in proximity to certain game objects for networking purposes, it needs a Network Identity to know which specific instance of the object it is referring to.

Without a Network Identity, the Network Proximity Checker would lack the necessary information to operate correctly. The Network Identity ensures proper synchronization and communication between networked instances, allowing the game to manage visibility and interactions appropriately. This makes it a foundational component in networked games, ensuring that game objects behave consistently across different clients in a multiplayer environment.
