I want to use a blueprint class from another blueprint class.

I want to use EndCheck in A blueprint class in Branch of B blueprint class.

After completing the operation in A, the boolean EndCheck variable changes to True, and I want to make it work only if EndCheck in B is true.

When you click on the picture, A and B are written in the description.
(Maybe the first picture is A.)

I used a translator because I couldn’t speak English. If you don’t understand, please leave a comment.
