๐ Actually I code that scene part, out of outer loop in IntelliJ IDEA
community edition. That's why it works. Actually I am feeling embarrassed
to ask for this question now. I should be more careful. By the way, I have
no tutor or mentor. Whatever I learn, I learned it myself. I learned in
computer science an online university which is located in the USA. That's
why I ask you all the time for any type of help. You people are amazing.
