|A basic jRPG inspired textbox (Scaled 2x)|
The next order of business is to build on the textbox and add support for dialog boxes. A dialog box allows a lengthy piece of dialog to be split into multiple textboxes with a prompt to advance between them. I'll also cover additional elements at this point like an avatar portrait and title for the person speaking. Then a few examples that show how versatile these boxes are and then moving on to other elements such as the ProgressBar.
GUI isn't the most exciting topic but it's quite essential for any large RPG and there's definitely an element of enjoyable craftsmanship in doing it well. The GUI section also has the benefit of being rather small, we build a toolbox of useful elements that are then used throughout the rest of the book.
