Unique ID

Unique ID

A Unique ID is a globally unique identifier (GUID) assigned to physics-interactive objects in the engine — entities, vehicles, heroes, items, and more.

Unique IDs allow you to save a reference to a specific object in a Variable and access it later, regardless of where it is in the game world. This is the most flexible way to reference objects and is used by commands like Save Unique ID and the "By Unique ID" option in Actor References and Physics Object References.
