Alright, this shouldn't be to hard to explain, -Set the bones spawn location by setting what the X and Y position are. -Set the direction the bone is going to face. -Set the size. [1-20 only] -Set the speed of the bone. Adding a negative will make it go backwards. -Set the color of the bone. There's white, blue, and orange.
Toby Fox for Undertale. @zambie2020 for the sprites and most of, if not all of the code. Also I kinda copied their thumbnail design. Use with credit!!!
