Problem description:

I'm unsure of which section of the forum to post this, but I'm working on a Pokemon Game, and I've been meaning to study interface and all that so I knew how to code what I intended on coding.

I want to make an interface window similar to actual pokemon games, where the battle window pops up and can be worked like a classic GBA Pokemon game, but the problem is, I have no idea where to start.

This is an example of what I'm trying to do. I've seen it done many times before, only I legit have no clue how it's done. I was told to focus on output, buuuuuut..?

If anyone has any guides, or pointers that could help me out, I'd really appreciate the help.~

This tutorial by Lummox JR should set you on the right path.
Look up the following:

screen loc(you'll be needing this to display to the second map element you'll need to use in order to display the battle in a new window)


Honestly, it is very simple to replicate the mechanics behind that picture of Pokemon Atom. I would show you an example but it's a pain to type all of it out on a phone.
