Godot

godot-rust v0.3 brings type-safe signals to the table.
If you register a signal:

#[signal]
fn damage_taken(amount: i32);

you can now freely connect it with other Rust functions:

fn ready(&mut self) {
    // Connect signal to the method:
    self.signals().damage_taken().connect(Self::on_damage_taken);
    
    // Or to an ad-hoc closure:
    self.signals().damage_taken().connect(|amount| {
        println!("Damage taken: {}", amount);
    });
    
    // Or to a method of another object:
    let stats: Gd<Stats>;
    self.signals().damage_taken().connect_other(&stats, |stats, amount| {
        stats.update_total_damage(amount);
    });
}

Emitting is also type-safe:

self.signals().damage_taken().emit(42);

Furthermore, you can now await signals, effectively introducing async tasks:

godot::task::spawn(async move {
    godot_print!("Wait for damage to occur...");
    
    let (dmg,) = player.signals().damage_taken().to_future().await;
    godot_print!("Player took {dmg} damage.");
});

There are many other improvements, see devlog and feel free to ask me anything :)

Huge thanks to all the contributors who helped ship these features!

very awesome to see tutorial and encouragement for 3D game
Godot would get much greater recognition if there were more 3D games made with it.

Added the swords to have something else for a change than boxes in all ratios. And, well, every Bulletheaven game needs something to collect, right?

A few seconds longer and it would take off like a choppa

ofc the boxes should be swords or something like that

Wanted to have them orbiting while maintaining center alignment, didn't fully work out ¯_(ツ)_/¯ But I do kinda like it

After having cancelled my 2 previous projects I've finally been able to finish something!

About: Nairu is a simple note taking app that I made mostly for myself, right now it doesn't have a lot of features (just the basics of a note taking app), but I plan to add a few more things to it.

Any feedback is appreciated!

I'm not the author, but posting it here because it is amazing project that deserves exposure.

I am writing a GDExtension for binding libpd, library version of PureData. I have added a property with appropriate getter and seterr.

  ADD_PROPERTY(
      PropertyInfo(Variant::STRING, "patch_path", PROPERTY_HINT_FILE, "*.pd"),
      "set_patch_path", "get_patch_path");

I do something like this to get the file path and load it to puredata

Ref<FileAccess> file = FileAccess::open(path, FileAccess::READ);
patch = pd.openPatch(
      file->get_path_absolute().utf8().get_data()->get_path_absolute().utf8().get_data(), "/");

I can select *.pd files from my resources directory, they load and work normally inside the editor. However, they do not work when I export the project.
