This video is about creating a Diablo 2 Skill Tree Style Functionality, in Unreal 5.4 Blueprints.
We start by adding some missed Text Controls to the Skill Tree Widget, along with a Button Clicked Function we’ll fill out later, but is called next in the Skill Tree Button Widget’s Blueprint code. With the Skill Tree Button forwarding Button Click to the Skill Tree, we then update the functionality there to track points spent, validate when each button should be enabled, and lastly, fix a little bug where Max Level wasn’t being set on the Buttons.
