#45 Skill Tree | Setup Foundation | RPG Framework in Unreal Engine 5
In this tutorial, we’ll build the foundation for an advanced Skill Tree System in Unreal Engine 5 using C++ and the Gameplay Ability System (GAS).
By the end of this video, you’ll have a working setup that automatically discovers, caches, and saves skill tree abilities — complete with developer settings, a dedicated subsystem, and a robust save/load system. This is the first step in creating a fully modular, data-driven RPG skill tree framework.
You’ll learn how to:
✅ Create a custom Gameplay Ability subclass for skill tree abilities
✅ Add Developer Settings to control where abilities are discovered
✅ Build a Game Instance Subsystem to load and cache abilities efficiently
✅ Implement a Save Game system for persisting unlocked abilities and skill points
✅ Develop a Skill Tree Component to manage ability unlocking, prerequisites, and upgrades
✅ Integrate Blueprint events and Gameplay Events for level-up handling and debugging
✅ Test everything using GAS Debugger and verify ability persistence between sessions
