Enums in Unreal Engine 4 Blueprints

In this guide we will be going over what Enums are in Unreal Engine 4 and how they are used in engine.

What is an Enum?

An Enum (also known as Enumeration) is used to give names to integer values.

For example, a basic game menu state can be represented as names and programmed as integer numbers.

– 0 = Mainmenu
– 1 = Game
– 2 = Pause
– 3 = Gameover

All game engines can use enums as they are a basic programming feature. Unreal engine can use enums in c++ and blueprints.

In the next section we will be creating our own Enum in Unreal Engine 4 Blueprints.

Creating the Enum

Firstly, right click the content browser and hover over the blueprints tab.

Click the Enumeration button to make the enum.

Creating the new enum asset

Secondly, add the names that you need for your enum.

Adding new values to the enum

In this example we will be using mainmenu, game, pause and gameover.

All the values added to the enum for this guide

Using the Enum

Lastly, with your new ENUM we can trigger different logic based on the value.

This can be done easily using a switch node.

Right click in any blueprint class and type “Switch on YOUR-ENUM-NAME”. In this case the node is called “Switch on gamestate”.

Running different blueprint nodes based on the enum gamestate

If you don’t know how to use switch nodes check out our guide here.


Now you have a working blueprint enum in Unreal Engine 4!

Even though this guide is short, We felt it was essential as there are very few guides for creating and using enums in blueprints.

Enums are extremely useful and most projects have many uses.

In future guides we will be using enums frequently which is why this guide is important for the future content of the site!
