gpn-tron

A small Rust client library for the GPN Tron game. Built for GPN 24 in Karlsruhe.

Run the demo bot

The crate ships with a DemoBot that just walks straight and turns when it would crash:

use gpn_tron::{GpnTronBot, demobot::DemoBot};

#[tokio::main]
async fn main() {
    let mut bot = DemoBot::new();
    bot.start("localhost", 4000, "myname", "mypassword")
        .await
        .unwrap();
}

Write your own bot

Implement [GpnTronBot::handle_packet] and react to ticks. Here is a bot that just runs in a circle:

use gpn_tron::{
    Bot, GpnTronBot,
    packets::{MoveDirection, ServerPacket},
};

struct CircleBot {
    direction: MoveDirection,
}

impl GpnTronBot for CircleBot {
    fn handle_packet(&mut self, bot: &mut Bot, packet: ServerPacket) {
        if let ServerPacket::Tick = packet {
            self.direction = match self.direction {
                MoveDirection::Up => MoveDirection::Right,
                MoveDirection::Right => MoveDirection::Down,
                MoveDirection::Down => MoveDirection::Left,
                MoveDirection::Left => MoveDirection::Up,
            };
            bot.do_move(self.direction);
        }
    }
}

#[tokio::main]
async fn main() {
    let mut bot = CircleBot { direction: MoveDirection::Up };
    bot.start("localhost", 4000, "circler", "supersecret")
        .await
        .unwrap();
}
