Currently how this project stands. It took me awhile, but I managed to compile the animations made thus far into a single frame size format, which I'll be displaying via a gif to show you how centered I made the animations. The reason for a lot of the blank space behind the sprite is so the character will stay in the center when turning around, and not say, pop within another area because the animation space was only made to accommodate one direction. It'll naturally be big enough for the sliding animation so no need to worry, I'll just add that as it comes.
Anyway, I'll be moving onto programing Sophia in the Games Factory, as well as the sub weapons. Currently though, I came to a conclusion on how to make the walking up/down stairs animations work. I will be including stairs within the game, but none to be traversed within areas where you can be harmed and need to combat to them or on them. They will simply be used to advance within certain portions of the stage. It will be automatic for most of them.
I have a few methods in mind for how to make some of the enemies to work, especially constantly spawning ones for certain locations. Some I may need to thinker around with a bit but I think I can manage.
Anyway, on a side note, for when Sophia's sliding animation is done, I'll see about asking Serio about adding her as a character to his/her fighter. Never hurts to try right? Anyway, this is currently where this project stands.
