use lootr::{Lootr, item::Item, drops::DropBuilder};
use rand_chacha::ChaCha20Rng;
use rand::SeedableRng;

(0..10).for_each(|_f| {
    let mut loot = Lootr::from(vec![
        Item::named("Socks"),
        Item::named("Boots"),
    ]);
    let drops = [DropBuilder::new().build()];

    let rng = &mut ChaCha20Rng::seed_from_u64(123);

    loot.loot_seeded(&drops, rng);
    loot.loot_seeded(&drops, rng);
    // ...

    // Will always loot Boots, then Socks, then Socks, then Boots ..
})

修饰符

Lootr.add_modifier() 允许给一些物品转换器添加修饰符。

修饰符是简单的函数，可以从给定的物品中返回一个新的物品。

use lootr::{Lootr, item::{Item, Props}, drops::DropBuilder};
let mut loot = Lootr::new();
loot.add(Item::a("crown"));

fn with_strength(source: Item) -> Item {
    source.extend(source.name, Props::from([
        ("strength", "10"),
    ]))
}

loot.add_modifier(with_strength);

//
// Then, at loot time:

let drops = [DropBuilder::new().modify().build()];

let rewards = loot.loot(&drops);

// rewards = [ crown{strength=10} ]

宏定义

为了使建筑更容易，您可以使用 bag! 宏。

let loot = bag! {
