Driving the appearance of a minimap through Blueprint logic

Now that we are familiar with dynamic UI elements, let’s continue exploring this topic by creating a minimap! This can be a nice extension to the compass we’ve just created, as both elements often appear side by side in games and apps. Furthermore, it will add a new layer of interactivity between what’s happening in the game and its visual representation on the UI. Let’s see what this is all about!

Getting ready
