Starting today a diary on the development of an online game, as a hobbie.

My goal is to use Rust and Go, two languages I have interest on learning, but don't have any experience.

Client will be implemented with Rust, while the server will be done using Go.

On this first day, I started by the client. My goal was to show a window and render anything. I found a library ggez and used it.

The result can be seen below:

On every update, it increments the counter.

The implemented code is below:

use ggez::{ContextBuilder, GameResult, event};
use ggez::graphics::{Canvas, Color, Text, DrawParam, PxScale};

struct Game {
    counter: u32, // a simple counter to track the number of frames
}

impl Game {
    fn new() -> Self {
        Game {
            counter: 0,
        }
    }
}

impl event::EventHandler for Game {
    fn update(&mut self, _ctx: &mut ggez::Context) -> GameResult {
        self.counter += 1; // Increment the counter on each update
        Ok(())
    }

    fn draw(&mut self, ctx: &mut ggez::Context) -> GameResult {
        // Clear the screen with a background color
        let mut canvas = Canvas::from_frame(ctx, Color::BLACK);

        let mut counter_text = Text::new(format!("Counter: {}", self.counter));
        counter_text.set_scale(PxScale::from(48.0)); // Set the font size to 48 pixels

        canvas.draw(&counter_text, DrawParam::default().dest([50.0, 50.0]));

        canvas.finish(ctx)?;
        Ok(())
    }
}

fn main() -> GameResult {
    let (ctx, event_loop) = ContextBuilder::new("rpg-client", "Victor Melo")
        .window_setup(ggez::conf::WindowSetup::default().title("RPG Client"))
        .window_mode(ggez::conf::WindowMode::default().dimensions(1280.0, 720.0)) // Set window size to 1280x720
        .build()
        .unwrap();

    let game = Game::new();
    event::run(ctx, event_loop, game)
}
