Some of this information may seem obvious if you've been using Godot for a while, but I'll include it anyway since I didn't know for a while.
You're probably gonna want to spend most of your time in the pets-lib folder.
This is where the Rust side of the codebase is in. The pets-gd folder has the
Godot project, but that's edited with the actual Godot editor. Plus, there are
symlinks to most of the important stuff in pets-lib anyway.
When you finish making changes, build the library with cargo run and start the
game. Pretty self-explanatory from there. For quick edits, cargo-watch is your
friend.
There's a quickstart script in pets-lib for my CLI text editor bois. The
./run script just opens the main scene using the godot command with whatever
arguments you give. This is pretty nice for testing purposes, but don't worry
about reloading the editor each time... Hot reloads are now supported by Godot!
You should only have to reload it when making a new class or changing fields on
a class, or anything along those lines.
Refer to
this wiki page
for arguments n stuff to pass into these scripts. One useful argument is -e,
which opens the editor instead of running the scene as a game.
