Struct FruitsManager

pub struct FruitsManager<'a, 'b: 'a> {
    fruits: Vec<Fruit<'a>>,
    carte: Arc<RwLock<Map<'b>>>,
}

Manages fruit objects within the game logic. Map outlive fruits, so ’b lifetime >= ’a (fruits) lifetime

Fields

fruits: Vec<Fruit<'a>>

carte: Arc<RwLock<Map<'b>>>

Implementations

impl<'a, 'b> FruitsManager<'a, 'b>

pub fn new(nb: u16, carte: Arc<RwLock<Map<'b>>>) -> Self

Creates a new FruitsManager with a given number of fruits.

Panics

if guard cannot be got for Map (whenever a previous panic poisoned guard)

Example

use std::sync::{Arc, RwLock};
use ratatui::layout::Rect;
use rsnaker::game_logic::fruits_manager::FruitsManager;
use rsnaker::graphics::sprites::map::Map;
let x =42;
let map = Arc::new(RwLock::new(Map::new(2, Rect::new(0,0, 160,10))));
let manager = FruitsManager::new(3, map);

fn spawn_random(carte: &Map<'_>) -> Fruit<'a>

Spawns a fruit at a random position on the map.

pub fn replace_fruits(&mut self, fruits_to_remove: &[Fruit<'a>])

Replaces eaten fruits with new random ones and ensures balance.

Panics

if guard cannot be got for Map (whenever a previous panic poisoned guard)

pub fn eat_some_fruits(&self, position: &Position) -> Option<Vec<Fruit<'a>>>

Returns a list of fruits at the given position, copying them to avoid lock contention.

fn generate_position_rounded_by_cs(carte: &Map<'_>) -> Position

Generates a random valid position for spawning fruits.

pub(crate) fn resize_to_terminal(&mut self)

Trait Implementations

impl<'a> Widget for &FruitsManager<'a, 'a>

fn render(self, area: Rect, buf: &mut Buffer)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom widget.

impl<'a> Widget for FruitsManager<'a, 'a>

Implements Widget for compatibility with older versions.

fn render(self, area: Rect, buf: &mut Buffer)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom widget.

impl<'a> WidgetRef for FruitsManager<'a, 'a>

Implements WidgetRef for rendering fruits on the screen.

fn render_ref(&self, area: Rect, buf: &mut Buffer)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom widget.
