You can find all my blogs and tutorials over at tomlooman.com. I have many Unreal Engine and C++ focused tutorials and learning resources.

Action Roguelike (C++ Course Project)

Browse Repository

This project is part of the Professional Game Development in C++ and Unreal Engine Course where we build this project step-by-step.

Survival Game (C++ Sample Project)

Browse Repository

Third-person survival game for Unreal Engine made entirely in C++. Originally built as six part tutorial series for Epic Games, now available as open-source C++ sample project.

Unreal Engine C++ Pro Course

In 2020 I taught a full curriculum at Stanford University for Unreal Engine C++. You can now enroll in this course yourself using the links below.

Professional Game Development in C++ and Unreal Engine

The C++ Course features include building of a C++ game framework including an "action system" and event-driven code for flexible and re-usable game code the "unreal way". Multiplayer features, AI bots, SaveGame system, async loading of content, UMG menus and UI and so much more!
