Make Your Nodes Queryable

You can still make custom Node classes as you would in gdext, BUT your custom nodes will not be queryable unless you add the KissingNode derive.

use godot::prelude::*;
use godot::classes::Sprite2D;
use bevy_kissing_godot::prelude::*;

#[derive(GodotClass, KissingNode)]
#[class(init, base=Sprite2D)]
struct Player {
    base: Base<Sprite2D>,
}

This will now work:

use godot::prelude::*;
use bevy::prelude::*;
use bevy_kissing_godot::prelude::*;

#[kiss_bevy(node_name = PoopPeeKisser)]
fn main(app: &mut App) {
	app.add_scedule(Process, update_float);
}

#[derive(Component)]
struct Floaty {
	vertical_speed: real,
}

fn update_float(
	player: Single<
		(&Floaty, &GodotNodeId),
		With<GodotNode<Player>> // only Player
	>,
	delta: Res<ProcessDelta>,
	all_nodes: NonSend<AllNodes>,
) {
	let (floaty, player_id) = player.into_inner();
	// do stuff
}
