Tiles

In case you haven’t noticed, the most prevolent thing in the world of STARBLOOM is tiles. Naturally, when modding STARBLOOM, you might want to add more types of tiles. This is increadably easy.

use bevy_ecs::prelude::*;
use macroquad::prelude::*;

pub const TILE_SIZE: f32 = 16.;

pub type TileRepr = u16;

pub struct Tile {
    pub renderable: bool,
}

impl Tile {
    pub const fn declare(renderable: bool) -> Self {
        Self { renderable }
    }
}

#[derive(Resource)]
pub struct TileRegestry {
    ids: std::collections::BTreeMap<TileRepr, &'static str>,
    entries: std::collections::HashMap<&'static str, Tile>,
}

impl TileRegestry {
    pub fn new() -> Self {
        Self {
            ids: std::collections::BTreeMap::new(),
            entries: std::collections::HashMap::new(),
        }
    }

    pub fn regester(&mut self, id: &'static str, tile: Tile) {
        self.entries.insert(id, tile);
        if self.ids.values().find(|v| **v == id).is_none() {
            self.ids.insert(self.ids.len() as TileRepr, id);
        }
        info!("Regestered tile '{}'", id);
    }

    pub fn get_tile_by_idx(&self, idx: &TileRepr) -> &Tile {
        self.entries
            .get(self.ids.get(idx).expect("bad tile idx"))
            .expect("Bad tile idx")
    }
}
