Question 4

Which data type in Blueprints would you use to store both a location, rotation, and scale together?

Accepted Answer

Transform

Answer

A Transform struct combines Location (Vector), Rotation (Rotator), and Scale (Vector) into a single variable.

Question 5

What happens to Blueprint variable default values when you change the variable's type?

The default value is reset to the new type's default

Changing a variable's type resets its default value to the new type's default, so any previously set default is lost.
