Unreal Engine Blueprints Functions, Events, and Macros 2

Question 1

What happens when you call a Function node that has no Return Node in Blueprints?

Accepted Answer

The function returns a default value for each output pin type

Answer

If a Blueprint function has output pins but no Return Node, those outputs return default values (0, false, empty string, etc.).

Question 2

Which keyword correctly describes a Blueprint Macro's execution pins compared to a Function's execution pins?

Accepted Answer

Macros can have multiple input and output execution pins; Functions have exactly one of each

Answer

Blueprint Macros support multiple input and output execution pins, making them suitable for branching logic, unlike functions which have a single entry and exit.

Question 3

In Blueprints, what is the primary reason Custom Events can be called from other Blueprints while standard graph events (like BeginPlay) cannot be triggered externally?

Accepted Answer

Custom Events appear as callable nodes when you reference another Blueprint's object

Answer

Custom Events generate a callable node that appears in other Blueprints when you have a reference to the owning actor, making cross-Blueprint calls straightforward.

Question 4

What does checking 'Pure' on a Blueprint Function do?

Accepted Answer

Removes execution pins so the function can be used inline like a getter

Answer

Marking a function Pure removes its execution pins, allowing it to be wired directly into data inputs without needing an execution wire.

Question 5

A Blueprint Macro is placed in a MacroLibrary asset. Which statement about this macro is TRUE?

Accepted Answer

It can be used by any Blueprint that includes the MacroLibrary without needing an object reference

Answer

Macros in a Blueprint MacroLibrary are accessible globally to any Blueprint that has the library referenced, with no object instance required.
