✍️ Sample Unreal Engine Blueprints Questions & Answers
1. Which Blueprint structure is most appropriate for storing an inventory where each item name maps to a quantity count?
A Map lets you look up any item's quantity directly by name in O(1) without iterating the entire list.
2. A Blueprint Map is declared as Map. What type must the keys be when you call 'Add' on it?
Blueprint container types are strictly typed at declaration; you cannot add a key of a different type without an explicit conversion.
3. How can you prevent a spawned actor from being destroyed when the level transitions in Blueprints?
Checking 'Persist Between Levels' (or 'Should Persist' in Blueprint settings) on an actor prevents Unreal from destroying it during seamless level transitions.
4. When should you prefer 'Set Render Opacity' over 'Set Visibility (Hidden)' for a UMG widget?
Set Render Opacity allows a gradual fade and keeps the widget in the layout and hit-testable, whereas Hidden removes it from hit-testing and can affect layout.
5. What Blueprint variable type would you use to store a player's name?
String is the standard type for storing arbitrary character sequences like player names in Blueprints.
6. In a Widget Blueprint, what is the purpose of the 'Is Variable' checkbox on a widget in the Designer?
Checking 'Is Variable' promotes the widget to a Blueprint variable so you can reference and manipulate it in the Event Graph.
