Hi!

There’s a short tutorial showing how to go from Flappy Dragon to the bonus version on the book’s website: From Flappy Dragon to Flappy Bonus · Hands-On Rust

I agree that some extra documentation would be a good idea. For now, if you clone the Github repo (GitHub - amethyst/bracket-lib: The Roguelike Toolkit (RLTK), implemented for Rust.) and cd into bracket-terminal, you can type cargo run --example and get a list of the examples (run by adding the example name, e.g. cargo run --example dwarfmap). The source code for all of these is in the examples directory. I’ve tried to annotate the examples to explain what’s going on.

I’ll try and get a better set of documentation posted at some point soon (it’s hard to give an exact timeframe). Some parts of the library are very mature/stable (the simple/sparse consoles, and probably the “fancy” console). Documenting those should be pretty straightforward. The sprite system is pretty new, so documentation for it will have to wait it to stabilize.

If you want to go far beyond the examples in Hands-on Rust, I recommend taking a look at the Amethyst and Bevy engines. Bracket-lib is designed as a teaching tool—so it sacrifices performance in the name of teach-ability in a few cases. Both Bevy and Amethyst use the same ECS approach as the book, and (especially Bevy) are developing a great body of examples and tutorials. I also know of at least one reader who implemented all of the book’s examples using Macroquad instead of bracket-lib, retaining the Legion and ECS elements. I’ve not used Macroquad enough to recommend or not-recommend it.
