Hour of Code Lesson 3: Reach New Heights with Power-ups and Collectibles: Working with Public Variables in Unreal Engine
In this lesson, students will add a power-up that enables the player to reach platforms that are much higher than they can currently reach. We’ll explore Blueprints, the visual-scripting system for Unreal Engine, and make changes to the variables responsible for the desired outcome. Then students will add coin pickups to entice the player to jump to these out-of-the-way places.
