World-Building with UEFN

Unreal Editor for Fortnite: The Ultimate Sandbox 🏜️

Welcome to the big leagues! Have you ever wanted to direct a movie or build a world inside a video game? With UEFN (Unreal Editor for Fortnite), you can! UEFN is a massive creation engine based on the same tools pro developers use.

It's like getting the ultimate LEGO set for Fortnite, where you can build anything you can imagine *and* direct your own action movie inside it. 🎬

AI-Powered Pre-Production 🤖

Even pro designers need inspiration! Before they spend hours building, they often use AI to brainstorm ideas and visualize a scene. This is called "pre-production," and it's a key part of how real games are made. Let's try it!

Describe your dream movie set to our AI Set Designer, and it will give you a list of the exact UEFN props and lighting settings to get you started!

Your First Mission: Block It Out! 🧱

Got your blueprint? Awesome! Your first mission is to "block out" your level. This means using simple shapes like cubes, spheres, and ramps to build the basic layout. Don't worry about details yet—just get the big shapes in place!

Challenge: Open UEFN and try to build the basic layout of the set the AI just described using only primitive shapes. Can you make the main building? The race track path? The deck of the ship? Go for it!

Level Up: An Introduction to Verse 📜

Building cool maps is amazing, but what if you want to create your own game rules? That's where Verse comes in! Verse is the special programming language created just for UEFN. It's how you make things interactive—like creating a button that gives the player a super-jump power-up!

Here’s a tiny Verse script. This code makes a message appear on screen when the game starts. It’s your first step to creating custom game rules!

using { /Fortnite.com/Devices }
using { /Verse.org/Simulation }

# A device that prints a message when the game starts
hello_world_device := class(creative_device):

    # Runs when the device is started
    OnBegin():void=
        Print("Hello, world! Your game has started! 🚀")

Drop this into a new Verse device in UEFN, and you've written your first line of functional code. You're officially a programmer!

The AI Stunt Double: Animating with Prompts 🤸

Animating a character doing a cool backflip can take weeks to learn. But with AI, you can become an animator in minutes! This is the idea behind the "AI Stunt Double."

Tools like Luma AI's Genie let you type a description like "a joyful jumping animation" and get a 3D model with that animation built right in. You can then import these into UEFN to bring your characters to life without needing to be an expert animator. It's maximum cool with minimum frustration!
