Plugin for Rust Bevy engine enabling you to store serialized prefabs for entities. Currently only .yaml file format is supported, hopefuly this crate will be format agnostic and will let u chose which deserializer to use.

All prefabs are stored in PrefabBank resource, in order to have PrefabBank available you need to add PrefabPlugin to your app, like so:

use bevy_prefabs::*;
use bevy::prelude::*;
fn main(){
  App::build()
      .add_plugin(PrefabPlugin);
}

In order to make your component a prefab it needs to derive Serializable, Deserializable, Clone and of course Prefab, for example:

#[derive(Prefab,Serialize,Deserialize,Clone)]
struct Weapon {
    damage: i32,
    range: f32
}

Loading a prefab with a system:

fn load_prefabs(mut prefab_bank: ResMut<PrefabBank>){
     prefab_bank
         .load_prefab("SomeItem","target/debug/prefabs/SomeItem".as_ref()).expect("Can't load prefab");
}

.load_prefab() method takes your desired name for the prefab (you will later use it to create entity with this prefab) and a path to the FOLDER where all serialized components for the prefab are stored in. Spawning a prefab now is super easy:

fn spawn_prefab(prefab_bank: Res<PrefabBank>, mut commands: Commands) {
    prefab_bank.spawn_prefab("SomeItem", &mut commands);
    prefab_bank.spawn_prefab("SomeItem", &mut commands);
    prefab_bank.spawn_prefab("SomeItem", &mut commands);
    prefab_bank.spawn_prefab("SomeItem", &mut commands);
}

To serialize existing component you need to serialize it as Prefab otherwise typetag will not be serialized and such component once deserialized will not be accepted in PrefabBank.
