Quick review of the course goals and information on the structure of the course
Course Book0:11

Install Unreal Engine 51:45
Learn how and where to install Unreal Engine so you are ready to build the interaction system
Jet Brains Rider2:08
Learn why Jet Brains Rider is a great IDE to use for Unreal Engine and why I use it
Unreal Engine Project Setup1:31
Lets setup a new C++ Unreal Engine project for the interaction system
UPDATE: Unreal Engine 5.60:17
A Review Programming Fundamentals0:07
A resource reviewing programming fundamentals
Section Quiz - Programming Fundamentals

Interaction System Introduction1:03
Introduction to Interactions Systems and what we will be building
What are Interactions?3:53
Answer the question of what actually are interactions and why they are important in video games.
Interaction System Requirements1:57
In order to build an interaction system we must have a set of requirements we can design for and then build
Traces and Colliders2:24
Two important concepts to detect things in our game world are traces and colliders - so lets discuss them and when to use them.
The Value of Interfaces2:32
Understanding the value of interfaces and when to use them is a crucial step in learning game development. This video explains why and how we will use interfaces in the interaction system.
Interaction System Design3:04
Finally lets review the design of our interaction system and how we are going to meet the requirements we set a few videos ago.
Section Quiz - Interactions, Colliders, and The Design

Base Interactable Actors (Blueprint)3:41
To interact with the items in our world we need to create a base interactable actor that we can build on top to support different types of items and actors.
Creating our Interaction Interface10:04
Lets build the interface for our interaction system
Input Action Mapping5:03
To capture the player's input we need to learn about and create Input Actions
Adding a Interaction Prompt Collider11:18
Adding colliders to enable us to prompt the player to interact
Interaction Distance Function8:40
A distance function will help determine which actor in the game world we can interact with or provide additional information for us to make that decision.
Interaction Prompt UI Widget11:01
Lets create a user widget to show the player how they can interact with the interactable actor in the world
Updating the Interaction Interface5:57
Adding final touches to the interaction interface
Section Quiz - Interfaces, Widgets, Input Actions and more!

Updating the Player Character5:15
Modify the existing third person template character to use the interaction system
Hiding the Interaction Prompt7:36
Add the ability to hide prompts when the player can no longer interact with the actor
Optimizing5:22
Interactable Actor Hints6:11
Now lets create a way to provide optional hints to the player on which items are interactable
Reviewing our Design and Finalizing5:00
Lets review our initial design and make sure we have met all the requirements with what we have built
Section Quiz - Hiding Prompts, Hints, and More

Requirements

A basic understanding of Unreal Engine 5 (navigating the editor, creating Blueprints)
Some familiarity with Blueprint scripting (variables, functions, events)
No prior C++ knowledge required but being open to learning a little will help
Enthusiasm to learn and build your own game systems

Description

Master one of the most essential systems in modern game development — the Interaction System. Whether you’re building an RPG, a Souls-like, or any game where players interact with objects in the world, this course will give you the skills to design and implement a professional, expandable interaction system in Unreal Engine 5.

In this step-by-step course, you’ll learn how to:

Programming Fundamentals with Blueprints, C++, and Unreal Engine with a e-book that is included with the course
Design and define interaction system requirements to understand the why and how we want to build such a system for our games

Design and build an interface with an Interact function that makes your interaction system modular and reusable across multiple objects
Create a base blueprint interactable actor to use as the foundation for all future interactable objects in your game
Set up input actions and mappings so your player can seamlessly trigger interactions in a flexible, scalable way
Design a custom widget with text and images that acts as a dynamic interaction prompt for the player
Implement distance-based logic to determine which object is closest and should display its prompt
Add an optional larger collider for interactable hints, guiding players toward important objects in your game world

By the end of the course, you’ll have built a fully functional, commercial-ready interaction system. This interaction system you can drop into RPGs, action-adventure games, survival games, or any project where players interact with the environment.

This course is designed for Unreal Engine beginners to intermediate developers, with a focus on both Blueprints and C++ to show you how professional developers combine both for maximum power.

If you’ve ever wanted to build gameplay that feels polished, responsive, and player-friendly, this course is for you.

Who this course is for:

Anyone who want to create interaction systems for RPGs, Souls-likes, or other genres
Beginners who have learned Unreal Engine basics and want to take the next step into system design
Intermediate developers looking to bridge Blueprints and C++
Anyone who wants to design reusable, expandable systems instead of quick hacks
