Blueprint Basics Unreal Engine: Enumerators
In this video, we’re diving into one of the simplest yet most powerful data structures in Unreal Engine Blueprints — Enumerators (Enums). Enumerators allow you to create a list of named options, making your code cleaner, more readable, and easier to manage. They are perfect for creating player states, game modes, weapon types, and any other situation where you need a list of named values.
What Are Enumerators (Enums) in Unreal Engine?
Enumerators (Enums) are a custom data type that allows you to create a list of named values. Each value is assigned a unique number, making them efficient and easy to use in your Blueprints. Enums are perfect for situations where you want to keep your code clean, readable, and bug-free.
How Enumerators (Enums) Work:
They store a list of named values that you define.
You can use them to represent states, modes, or types (like player states, enemy AI states, or weapon types).
Each Enum value is automatically assigned a number (starting from 0).
Enums are perfect for clean and readable logic.
Why Use Enumerators (Enums) in Unreal Engine?
Clean Code: Instead of using numbers or text strings, you can use named values (like "Idle", "Running").
Error Prevention: Avoids using invalid values because Enums are type-safe.
Easy to Understand: Makes your Blueprints more readable for you and your team.
Flexible: You can easily add, remove, or change Enum values as your game evolves.
