feat(Save & load): new crate bevy_gltf_save_load + lots of upgrades & improvements (#95) 

* feat(bevy_gltf_save_load): saving & loading implemented
   * created new crate for save & load features, uses & filters out blueprints for efficient loading
   * saving & loading, even with dynamically spawned nested hierarchies works 
   * component filter , resource filter & save path root are configurable
   * for saving: added removal & cleanup logic for children component with children
  that have been filtered out: ie no more invalid children getting stored in the save files !
   * added sending of event once saving is done

* feat(examples/save-load): example for the new crate
   * loading level static & dynamic data as blueprints
   * added a bit of ui when entering saving & loading states & cleanup when exiting

* feat(bevy_gltf_blueprints): significant rewrite of how the crate works
     * simplified spawning process, no more spawning children containing blueprints etc
     * simplified post process : instead of copying original entity  into blueprint root
      we now copy blueprint root data (components & children) into the original entity ! fixes #96 
     * much simpler code wise
     * solves issue with needing to register components that we only use on the bevy side (not gltf)
    since we are not copying the bevy data into the blueprints data
     * added **copyComponents** helper to copy components from one entity to another, excluding existing
     components on the target entity, & some bells & whistles
     * **Name** is now optional when spawning a blueprint: closes #97 
     * **Transform** is now optional when spawning a blueprint: closes #98 
     * removed transform from bundle (BREAKING change)
     * added (optional)  **NoInBlueprint** component to have finer control over whether to inject the **InBlueprint** component inside spawned blueprint entities
     * added (optional) **Library**  component, so we can override library path when we want
     * added (optional) **AddToGameWorld** component for convenience   to automatically add entities to the game world, if there is one

* chore(bevy_gltf_components): removed verbose output, cleaned it up a bit

* feat(tools/auto_export): added option to split out "dynamic" objects in main scenes
   * ie if a collection instance (or its original collection) has a "dynamic" (aka mutable, saveable etc)
     flag it can get exported to a seperate gltf file (essentially acting like an "initial save")
   * the rest of the levels (the "static" data) is exported without the dynamic objects and
     can be reused with save files !

- [bevy_gltf_save_load](./crates/bevy_gltf_save_load/) This crate adds the ability to save & load your game state in a relatively simple way, by leveraging the blueprint functionality of
bevy_gltf_blueprints to only save a minimal subset of dynamic data, seperating dynamic & static parts of levels etc.

* a ```BlueprintName``` component
* a ```SpawnHere``` component
* a ```TransformBundle``` sub-bundle (so we know where to spawn)
[```BluePrintBundle```](./src/lib.rs#22)
## Additional information
- When a blueprint is spawned, all its children entities (and nested children etc) also have an ```InBlueprint``` component that gets insert
- In cases where that is undesirable, you can add a ```NoInBlueprint``` component on the entity you spawn the blueprint with, and the components above will not be add
- if you want to overwrite the **path** where this crate looks for blueprints (gltf files) , you can add a ```Library``` component , and that will be used instead of the default path
ie :
```rust no_run
commands
.spawn((
Name::from("test"),
BluePrintBundle {
blueprint: BlueprintName("TestBlueprint".to_string()),
..Default::default()
},
Library("models".into()) // now the path to the blueprint above will be /assets/models/TestBlueprint.glb
))
```
- this crate also provides a special optional ```GameWorldTag``` component: this is useful when you want to keep all your spawned entities inside a root entity
You can use it in your queries to add your entities as children of this "world"
This way all your levels, your dynamic entities etc, are kept seperated from UI nodes & other entities that are not relevant to the game world
> Note: you should only have a SINGLE entity tagged with that component !
```rust no_run
commands.spawn((
SceneBundle {
scene: models
.get(game_assets.world.id())
.expect("main level should have been loaded")
.scenes[0]
.clone(),
..default()
},
bevy::prelude::Name::from("world"),
GameWorldTag, // here it is
));
```

the ordering of systems is very important !

# bevy_gltf_save_load
Built upon [bevy_gltf_blueprints](https://crates.io/crates/bevy_gltf_blueprints) this crate adds the ability to easilly **save** and **load** your game worlds for [Bevy](https://bevyengine.org/) .
* leverages blueprints & seperation between
* **dynamic** entities : entities that can change during the lifetime of your app/game
* **static** entities : entities that do NOT change (typically, a part of your levels/ environements)
* and allows allow for :
* a simple save/load workflow thanks to the above
* ability to specify **which entities** to save or to exclude
* ability to specify **which components** to save or to exclude
* ability to specify **which resources** to save or to exclude
* small(er) save files (only a portion of the entities is saved)
Particularly useful when using [Blender](https://www.blender.org/) as an editor for the [Bevy](https://bevyengine.org/) game engine, combined with the [Blender plugin](https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/tools/gltf_auto_export) that does a lot of the work for you (including spliting generating seperate gltf files for your static vs dynamic assets)
A bit of heads up:
* very opinionated !
* still in the early stages & not 100% feature complete
* fun fact: as the static level structure is stored seperatly, you can change your level layout & **still** reload an existing save file
## Usage
Here's a minimal usage example:
```toml

bevy_gltf_blueprints = "0.6" // also needed
```
```rust no_run
use bevy::prelude::*;
use bevy_gltf_save_load::*;
fn main() {
App::new()
.add_plugins((
DefaultPlugins,
SaveLoadPlugin::default()
))
.run();
}
// add a system to trigger saving
pub fn request_save(
mut save_requests: EventWriter<SaveRequest>,
keycode: Res<Input<KeyCode>>,
)
{
if keycode.just_pressed(KeyCode::S) {
save_requests.send(SaveRequest {
path: "save.scn.ron".into(),
})
}
}

take a look at the [example]('https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/bevy_gltf_save_load/basic/src/game/mod.rs) for more clarity
## Installation
Add the following to your `[dependencies]` section in `Cargo.toml`:
```toml
bevy_gltf_save_load = "0.1"
bevy_gltf_blueprints = "0.6" // also needed, as bevy_gltf_save_load does not re-export it at this time
```
Or use `cargo add`:
```toml
cargo add bevy_gltf_save_load
```
## Setup
```rust no_run
use bevy::prelude::*;
use bevy_gltf_save_load::*;
fn main() {
App::new()
.add_plugins((
DefaultPlugins
SaveLoadPlugin::default()
))
.run();
}
```
you likely need to configure your settings (otherwise, not much will be saved)
```rust no_run
use bevy::prelude::*;
use bevy_gltf_save_load::*;
fn main() {
App::new()
.add_plugins((
DefaultPlugins,
SaveLoadPlugin {
save_path: "scenes".into(), // where do we save files to (under assets for now) defaults to "scenes"
component_filter: SceneFilter::Allowlist(HashSet::from([ // this is using Bevy's build in SceneFilter, you can compose what components you want to allow/deny
TypeId::of::<Name>(),
TypeId::of::<Transform>(),
TypeId::of::<Velocity>(),
// and any other commponent you want to include/exclude
])),
resource_filter: SceneFilter::deny_all(), // same logic as above, but for resources : also be careful & remember to register your resources !
..Default::default()
},
// you need to configure the blueprints plugin as well (might be pre_configured in the future, but for now you need to do it manually)
BlueprintsPlugin {
library_folder: "models/library".into(),
format: GltfFormat::GLB,
aabbs: true,
..Default::default()
},
))
.run();
}
```
### How to make sure your entites will be saved
- only entites that have a **Dynamic** component will be saved ! (the component is provided as part of the crate)
- you can either add that component at runtime or have it baked-in in the Blueprint
### Component Filter:
- by default only the following components are going to be saved
- **Parent**
- **Children**
- **BlueprintName** : part of bevy_gltf_blueprints, used under the hood
- **SpawnHere** :part of bevy_gltf_blueprints, used under the hood
- **Dynamic** : included in this crate, allows you to tag components as dynamic aka saveable ! Use this to make sure your entities are saved !
- you **CANNOT** remove these as they are part of the boilerplate
- you **CAN** add however many other components you want, allow them all etc as you see fit
- you can find more information about the SceneFilter object [here](https://bevyengine.org/news/bevy-0-11/#scene-filtering) and [here](https://docs.rs/bevy/latest/bevy/scene/enum.SceneFilter.html)
## Events
- to trigger **saving** use the ```SaveRequest``` event
```rust no_run
// add a system to trigger saving
pub fn request_save(
mut save_requests: EventWriter<SaveRequest>,
keycode: Res<Input<KeyCode>>,
)
{
if keycode.just_pressed(KeyCode::S) {
save_requests.send(SaveRequest {
path: "save.scn.ron".into(),
})
}
}
```
- to trigger **loading** use the ```LoadRequest``` event
```rust no_run
// add a system to trigger saving
pub fn request_load(
mut load_requests: EventWriter<LoadRequest>,
keycode: Res<Input<KeyCode>>,
)
{
if keycode.just_pressed(KeyCode::L) {
save_requests.send(LoadRequest {
path: "save.scn.ron".into(),
})
}
}
```
- you also notified when saving / loading is done
- ```SavingFinished``` for saving
- ```LoadingFinished``` for loading
> Note: I **highly** recomend you change states when you start/finish saving & loading, otherwise things **will** get unpredictable
Please see [the example]('https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/bevy_gltf_save_load/basic/src/game/mod.rs#77') for this.
## Additional notes
- the name + path of the **static** level blueprint/gltf file will be saved as part of the save file, and reused to dynamically
load the correct static assets, which is necessary when you have multiple levels, and thus all required information to reload a save is contained within the save
## SystemSet
For convenience ```bevy_gltf_save_load``` provides two **SystemSets**
- [```LoadingSet```](./src/lib.rs#19)
- [```SavingSet```](./src/lib.rs#24)
## Examples
Highly advised to get a better understanding of how things work !
To get started I recomend looking at
- [world setup]('https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/bevy_gltf_save_load/basic/src/game/in_game.rs#13')
- [various events & co]('https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/bevy_gltf_save_load/basic/src/game/mod.rs#77')
All examples are here:
- https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/bevy_gltf_save_load/basic

# Basic save_load example/demo
This example showcases how to use ```bevy_save_load``` crate to save & load your bevy game
## Notes Workflow with blender / demo information
- the gltf files for this demo where generated using the **Export dynamic and static objects seperatly** feature of the auto_export addon:
so the static & dynamic level files where generated automatically, based on the entities that have a **Dynamic** component/custom property
## Running this example
```
cargo run --features bevy/dynamic_linking
```
