Question 1

Which Blueprint node type allows you to store a value and retrieve it later within the same Blueprint graph?

Accepted Answer

Blueprint Variable

Answer

Blueprint Variables are declared at the Blueprint class level and persist throughout the Blueprint's lifetime, allowing storage and retrieval of values.

Question 2

What happens when you call 'Destroy Actor' on an actor that is referenced by another Blueprint variable?

Accepted Answer

The variable is automatically set to None

Answer

When an actor is destroyed, all object references pointing to it become invalid (None/null) automatically.

Question 3

In Blueprint, what is the purpose of the 'Sequence' node?

Accepted Answer

Executes multiple output pins in order, one after another

Answer

The Sequence node fires its output execution pins (Then 0, Then 1, etc.) in top-to-bottom order, useful for organizing linear logic.

Question 4

Which variable type in Blueprints is most appropriate for storing a reference to any UObject-derived asset loaded at runtime?

Accepted Answer

Soft Object Reference

Answer

Soft Object References store a path to an asset without keeping it loaded in memory, enabling async loading at runtime.

Question 5

What is the difference between 'Pure' and 'Impure' Blueprint functions?

Accepted Answer

Pure functions have no execution pins and do not modify state; impure functions have execution pins

Answer

Pure functions (marked with a yellow diamond) lack execution pins and are re-evaluated each time their output is used, while impure functions are called explicitly via execution flow.
