Enums, or enumerations, are introduced as a data type that defines a set of named values, significantly improving code readability and reducing errors []. Instead of using raw numbers or strings, developers can employ meaningful names for constants like game states or user roles []. An essential example is the "EGate" enum, which helps track a character's current movement state—such as idle, walk, sprint, crouch, or prone []. The inclusion of `BlueprintType` allows these enums to be visible and usable within Unreal Engine's visual scripting environment []. Furthermore, `meta` tags can be used to customize the display name in blueprints, ensuring clarity even if the underlying code name is different (e.g., "walk" displayed as "walking") [].
