This Unreal Engine 5.4 video is about adding the User Interface for Win vs Loss Conditions.
We start by Importing the detail-crystal-large.fbx file into the TowerDefenseKit folder, and placing it in the level. We next create the Summary Widget Blueprint with a Win vs Loss Text Control, and a Button to restart the level, and then add it to the HUD Widget Blueprint. Lastly, we hook up the Logic from the previous video to these UI Bits.
Edit: The WBP_Summary should be below the HeartHealthBar (in WBP_HUD) so that the Bar is not visible during Summary.
