Unreal Engine Blueprints Unreal Engine Blueprints MCQ 2 — Questions and Answers
Question 1: Which Blueprint node type is used to delay execution by a specified number of seconds?
- Timer by Event
- Delay (Correct answer)
- Set Timer by Function Name
- Retriggerable Delay
Correct answer: Delay
The Delay node pauses Blueprint execution for a specified duration before continuing to the next node.
Question 2: In Blueprints, what does the 'Cast To' node return if the cast fails?
- Null reference
- Default object of the target class
- The original object unchanged
- It triggers the 'Cast Failed' execution pin (Correct answer)
Correct answer: It triggers the 'Cast Failed' execution pin
When a Cast To node fails, execution flows through the 'Cast Failed' output pin rather than the success pin.
Question 3: What is the purpose of the 'Spawn Actor from Class' node in Blueprints?
- Loads an asset from disk at runtime
- Creates a new instance of an Actor class in the world (Correct answer)
- Duplicates an existing Actor in the scene
- Instantiates a UObject without placing it in the world
Correct answer: Creates a new instance of an Actor class in the world
Spawn Actor from Class instantiates a new Actor of the specified class and places it in the game world at a given transform.
Question 4: Which pin color represents a Boolean data type in Unreal Engine Blueprints?
- Red
- Green
- Dark red / maroon (Correct answer)
- Blue
Correct answer: Dark red / maroon
Boolean pins are displayed in dark red (maroon) in the Blueprint graph editor.
Question 5: What does 'Tick' refer to in the context of an Actor Blueprint's Event Graph?
- A one-time initialization event at game start
- A collision detection callback
- A per-frame update event called every rendered frame (Correct answer)
- A networking synchronization pulse
Correct answer: A per-frame update event called every rendered frame
Event Tick fires every frame and is used to run logic that must update continuously, such as movement or timer logic.
Question 6: In Blueprints, which node allows you to get the player's character reference?
- Get Player Pawn
- Get Player Controller
- Get Player Character (Correct answer)
- Get Controlled Pawn
Correct answer: Get Player Character
Get Player Character returns a reference to the ACharacter instance controlled by the specified player index.
Question 7: What is a 'Pure' function in Blueprints?
- A function that can only be called from C++
- A function with no execution pins that does not modify state (Correct answer)
- A function that always returns the same output regardless of input
- A function visible only within its own Blueprint
Correct answer: A function with no execution pins that does not modify state
Pure functions have no execution (white) pins and are expected to have no side effects, only returning computed values.
