- Ability to specify project root dir for template-core.
- Optional app arguments. Prevents crash when trying to parse program arguments.
- Change key bindings to make more intuitive up/down motion.
- Replaced `SurfaceSharedData` into `Resource<SurfaceData>`
    - Surface shared data was essentially a resource of some sort anyway.
    - Allows saving meshes as resources externally.
    - Allows using standard resource pipeline for surface data.
- Simplified camera picking API in the editor.
- Improved terrain brush system.
- Print surface resource kind in the property editor.
- Fixed new object placement.
    - Children objects will stay at (0,0,0).
    - When creating via "Create" menu, a new object will be located in front of the camera.
    - When creating a parent object whose parent is root, it will also be located in front of the camera.
- Ability to specify name column width of inspector widget.
- Save camera projection mode in editor settings.
- Refactored editor camera controller - allows dragging the camera using mmb in 2d mode.
- Sort items of built-in resources.
- Remove native collider when its shape cannot be created.
- Hijack control over animations from animation container in ABSM - now ABSM itself updates the animations it uses,
  and only those that are currently used either by a state or states of active transition.
- Extract the rendering framework into a separate crate.
- Make fbx elements of mesh geometry optional.
    - Prints a warning message and continues reading.
    - This is needed to be able to load "malformed" fbx, that has no mesh geometry, such as animation-only fbx.
- Enable resource hot reloading by default in executor.
- Move `rotateVec2` to shared shader functions.
- Store initial data and file extension (if any) of built-in resources.

- Pass material properties using uniform buffers.
    - Automatically generate uniform buffer description for material properties.
    - Automatically define uniforms for samplers.
    - No more need to manually define material properties in shaders, just use `properies.your_property_name`.
- Isolated opengl-specific code of gpu program into its own module.
- Use uniform memory allocator to speed up uniform data upload to gpu.
    - Splits rendering of render bundles in two steps: uniform data collection + upload and the actual rendering.
    - More efficient use of memory by using all available space in uniform buffers (prevents having uniform.
      buffers with just 200–300 bytes of memory, where the actual memory block on gpu is 4 kb).
    - It significantly reduces the number of individual data transfers and gapi calls in general.
    - Improves performance by 12–15%.
- Removed redundant buffer binding/unbinding - saves some time on api calls (especially in WebGL, where everything is
  proxied through JS).
- Pass sceneDepth texture to shaders explicitly.
- Use explicit binding for textures. Prevents dozens of `glUniform1i` calls when drawing stuff, thus improving
  performance by 5–10% (more on WebAssembly, where each gl call is passed through JS).
- Refactored shader structure to include resource bindings.
    - Makes shader structure more rigid and removes implicit built-in variables.
    - Makes binding points of resources explicit.
- Turned `Matrix2Editor` into generic-over-size `MatrixEditor`.
- Use immutable string in shader property name.
- Reworked materials.
    - Material now stores only changed shader properties.
    - Move validation from set_property/bind to the renderer where it simply prints an error message to the log
      if something's wrong.
    - Removed fallback value from texture resource binding, it makes no sense to duplicate this info since the correct
      one is stored in the shader anyway.
    - Removed `default` property from texture definition in shaders.
- Collect light info when constructing a render bundle. Removes redundant loop over scene graph nodes.
- Refactor hot reload to allow custom dynamic plugins besides dylib-based.

  but its message was still in the queue.
- Replaced component querying from nodes with `ComponentProvider` trait.
- Turned editor inspector into a plugin.
- Cloning physics when cloning Graph to persist Scene settings when saving Scene from the editor.
- TabControl improvements..
- Changed `traverse_iter` to return a pair of handle and ref - much more convenient when there's a need to handle a
  handle with a reference at the same time, no need to do re-borrow which is double work anyway.
- Added `AnimationResource` which decoupled animation tracks data into a shared resource.
    - Significantly reduces memory consumption when cloning animations, since it does not need to clone the tracks
      anymore.
    - Animation resource can be shared across multiple animations using the same tracks.
    - Significantly speeds up the instantiation of animation player scene node.
    - Backward compatibility is preserved.
- Focus search bar's text box when focusing toolbar itself - toolbar focus makes no sense anyway, because it does not
  interact with keyboard, but text box does.
- Node selector usability improvements.
    - Focus search bar on open.
    - Ability to confirm selection by enter key.
    - Bring the first selected item into view on open.
    - Added tab navigation.
- Lazy z-index sorting instead of on-demand.
- Exclude samples buffer from a list of animatable properties.
- Improved property selector.
    - Focus search bar on opening.
    - Tab navigation.
    - Highlight selected properties on rebinding.
    - Ability to confirm selection by hitting the enter key.
- Detached material-related parts of the editor into its own plugin - material editor is now non-existent by default and
  created only when needed, which saves memory (both ram and vram) and cpu/gpu time.
- Detached ragdoll wizard into a separate plugin.
- Move the settings window into a separate plugin.
- Move the animation editor into its own plugin.
- Improved editor plugins api.
- Create animation editor on editor start if animation editor was docked before.
- Move the absm editor to a separate plugin.
- Create save file selector for prefabs on demand.
- Move the curve editor window into its own plugin.
- Move the path fixer into a plugin.

- Make tooltips invisible for hit test.
- Move the log panel to `fyrox-ui`.
- Keep the editor running until the active popup is fully shown.
- Change the default path of file browser to `./`.
- Disable log file by default. The log file could be undesirable in some cases, and now it is off by default and can be
  enabled by `Log::set_file_name/set_file` in `fn main`.
- Explicit api to change the log file.
- Replaced proprietary Arial font with Roboto in the editor.
- Do not precompile built-in shaders on engine start.
    - It is faster to compile them on-demand.
    - On WebAssembly such compilation could take 10–15 seconds.
- Detached texture-related code to separate crate. It allows attaching it to `fyrox-ui` to use textures directly without
  using hacky `UntypedResource`.
- Use TextureResource directly in ui code where possible - removes redundant juggling with untyped↔typed conversions.
- Force `Image` widget to use texture size on measurement stage - removes "surprising effect" with collapsed image, if
  width/height is not set explicitly.
- Audio initialization errors non-fatal now. It allows running the engine in environments without proper audio output
  support.
- Print editor version in the window title.
- Print editor version in the log on start.
- Replace the hardcoded version of the engine with the one from Cargo.toml. This is a semi-reliable solution, but much
  better than having the hardcoded version.
- Close projection (2d/3d) selector on selection.
- Use toggle button for `track selection` in the world viewer.
- Put the search bar of the world viewer on the same row with other buttons.
- Moved `load_image` to `fyrox-ui` utils.

## Removed

- Removed redundant data hash calculation in textures.
- Removed redundant field from render data bundle - `is_skinned` flag makes no sense, because it could be derived
  from bone matrix count anyway and it is always defined on the per-instance basis, not per-bundle.
- Remove redundant decal layer index from mesh/terrain/render the data bundle. These are residuals from before
  custom material era, it makes no sense now since decal layer index is defined in materials and these fields simply had
  no effect.
- Removed depth offset.
    - It could be done with shaders.
    - Removed because it adds unnecessary projection matrix juggling for each rendered instance.
- Removed implicit blend shapes storage passing to material shaders - it is now controlled directly from `Mesh` node,
  and it creates temp material to pass blend shape storage explicitly.
- Removed `PersistentIdentifier` and `MatrixStorageCache`.
- Removed `cast_shadows` property from `BaseLight` - this property at some point started to be redundant, because `Base`
  already has such property and the one in `BaseLight` must be deleted to prevent confusion.
- Remove an incorrect error message in the animation editor.
- Removed `Node::query_component_ref/mut`.
    - It duplicates existing functionality.
    - Replaced with `SceneGraphNode::component_ref/mut`.
- Removed redundant boxing when applying animation values - makes animation of arbitrary numeric properies significantly
  faster.

- `Plugin::on_ui_message`
- Two-step plugins initialization:
    - `PluginConstructor` trait defines a method that creates an instance of `Plugin` trait, instance of plugin
      constructor is used to create plugins on demand. It is needed because engine has deferred plugin initialization.
- `Framework` is removed, its functionality was merged with plugins.
- Simplified `ScriptConstructorContainer::add` definition, there were redundant generic parameters that just add
  visual clutter.
- Implemented `Clone+Debug` traits for `NavmeshAgent`

- High DPI screens support for the editor.
- Newly created cameras in the editor are now enabled by default.
- Added "Preview" option for cameras in world viewer.
- Refactored joints:
    - Joints binding now is fully automatic and it is based on world transform of the joint, no need to manually
      set local frames.
    - Rebinding happens when a joint changes its position
    - Joints editing in the editor is now much more intuitive
- Improved debug visualization for physics.
- Read-only mode for NumericUpDown and Vec2/Vec3/Vec4 widgets
- Show global coordinates of current selection in the scene previewer
- BitField widget - it helps you to edit numbers as bit containers, allowing you to switch separate bits
- More compact editors for properties in Inspector
- NumericUpDown widget does not use word wrapping by default anymore
- CheckBox widget can now be switched only by left mouse button
- Ability to disable contacts between connected bodies of a joint
- `style` parameter for project template generator - it defines which scene will be used by default - either `2d`
  or `3d`
- Ability to select portion of the texture to render in `Rectangle` nodes.
- Ability to generate script skeleton for template generator
- HSL color model
- Ability to copy log enties to the clipboard
- `Log` API improvements
- Visualize cameras in the editor
- Context menu for asset items, it is now possible to open, delete, show-in-explorer items and also
  to copy file name and full file path to the clipboard.
- Visualize point and spot lights in the editor.

# 0.26

This release is mostly to fix critical bugs of 0.25 and add missing functionality that stops you from using scripting
system.

- Added project template generator
- Fixed invisible selected item in drop-down list widget.
- Correctly sync node names in `World Viewer`
- Reset editor's camera projection mode switch when creating new scene
- Fixed doubling scene entities in `World Viewer` when loading scene via `StartupData`

- Fixed shader cache - now the engine won't re-compile shaders each 20 seconds.
- Temporarily disable `Lifetime` property editing because it causes crashes
- Do not show `dirty` flag of `Transform` in the `Inspector`
- Provide access to property editors container for editor's `Inspector` - it is now possible
  to register your own property editors
- Fixed panic when syncing `Inspector` for an entity with `Option<Texture>` field.
- Added `handle_object_property_changed` and `handle_collection_property_changed` macros to reduce
  boilerplate code in script property handling.

## Migration guide

**WARNING:** This release **does not** provide legacy sound system conversion to new one, which means if
any of your scene had any sound, they will be lost!

Now there is limited access to `fyrox_sound` entities, there is no way to create sound contexts, sounds,
effects manually. You have to use respective scene nodes (`Sound`, `Listener`) and `Effect` from
`fyrox::scene::sound` module (and children modules).

### Nodes

Since `Node` enumeration was removed, there is a new way of managing nodes:

- `Node` now is just `Box<dyn NodeTrait>` wrapped in a new-type-struct.
- Pattern matching was replaced with `cast` and `cast_mut` methods.
- In addition to `cast/cast_mut` there are two more complex methods for polymorphism: `query_component_ref` and
  `query_component_mut` which are able to extract references to internal parts of the nodes. This now has only one
  usage - `Light` enumeration was removed and `PointLight`, `SpotLight`, `DirectionalLight` provides unified access
  to `BaseLight` component via `query_component_ref/query_component_mut`. `query_component` could be a bit slower,
  since it might involve additional branching while attempting to query component.
- `Base` node was replaced with `Pivot` node (and respective `PivotBuilder`), it happend due to problems with
  `Deref<Target = Base>/DerefMut` implementation, if `Base` is implementing `NodeTrait` then it must implement `Deref`
  but implementing `Deref` for `Base` causes infinite deref coercion loop.
- To be able to create custom scene nodes and having the ability to serialize/deserialize scene graph with such
  nodes, `NodeConstructorContainer` was added. It contains a simple map `UUID -> NodeConstructor` which allows to
  pick the right node constructor based on type uuid at deserialization stage.

#### Replacing `BaseBuilder` with `PivotBuilder`

It is very simply, just wrap `BaseBuilder` with a `PivotBuilder` and call `build` on `PivotBuilder` instance:

```rust
// Before
fn create_pivot_node(graph: &mut Graph) -> Handle<Node> {
    BaseBuilder::new().build(graph)
}

// After
fn create_pivot_node(graph: &mut Graph) -> Handle<Node> {
    PivotBuilder::new(BaseBuilder::new()).build(graph)
}
```

#### Pattern matching replacement

Pattern matching was replaced with 4 new methods `cast/cast_mut/query_component_ref/query_component_mut`:

```rust
fn set_sprite_color(node: &mut Node, color: Color) {
    // Use `cast_mut` when you are sure about the real node type.
    if let Some(sprite) = node.cast_mut::<Sprite>() {
        sprite.set_color(color);
    }
}

fn set_light_color(node: &mut Node, color: Color) {
    // Use query_component_mut if you unsure what is the exact type of the node.
    // In this example the `node` could be either PointLight, SpotLight, DirectionalLight,
    // since they're all provide access to `BaseLight` via `query_component_x` the function
    // will work with any of those types.
    if let Some(base_light) = node.query_component_mut::<BaseLight>() {
        base_light.set_color(color);
    }
}
```

### Listener

Now there is no need to manually sync position and orientation of the sound listener, all you need to do
instead is to create `Listener` node and attach it to your primary camera (or other scene node). Keep
in mind that the engine supports only one listener, which means that only one listener can be active
at a time. The engine will not stop you from having multiple listeners active, however only first (the
order is undefined) will be used to output sound.

### Sound sources

There is no more 2D/3D separation between sounds, all sounds in 3D by default. Every sound source now is
a scene node and can be created like so:

```rust
let sound = SoundBuilder::new(
BaseBuilder::new().with_local_transform(
TransformBuilder::new()
.with_local_position(position)
.build(),
),
)
.with_buffer(buffer.into())
.with_status(Status::Playing)
.with_play_once(true)
.with_gain(gain)
.with_radius(radius)
.with_rolloff_factor(rolloff_factor)
.build(graph);
```

Its API mimics `fyrox_sound` API so there should be now troubles in migration.

### Effects

Effects got a thin wrapper around `fyrox_sound` to make them compatible with `Sound` scene nodes, a reverb
effect instance can be created like so:

```rust
let reverb = ReverbEffectBuilder::new(BaseEffectBuilder::new().with_gain(0.7))
.with_wet(0.5)
.with_dry(0.5)
.with_decay_time(3.0)
.build( & mut scene.graph.sound_context);
```

A sound source can be attached to an effect like so:

```rust
graph
.sound_context
.effect_mut( self .reverb)
.inputs_mut()
.push(EffectInput {
sound,
filter: None,
});
```

### Filters

Effect input filters API remain unchanged.

### Engine initialization

`Engine::new` signature has changed to accept `EngineInitParams`, all previous argument were moved to the
structure. However, there are some new engine initialization parameters, like `serialization_context` and
`resource_manager`. Previously `resource_manager` was created implicitly, currently it has to be created
outside and passed to `EngineInitParams`. This is because of new `SerializationContext` which contains
a set of constructors for various types that may be used in the engine and be added by external plugins.
Typical engine initialization could look something like this:

```rust
use fyrox::engine::{Engine, EngineInitParams};
use fyrox::window::WindowBuilder;
use fyrox::engine::resource_manager::ResourceManager;
use fyrox::event_loop::EventLoop;
use std::sync::Arc;
use fyrox::engine::SerializationContext;

fn init_engine() {
    let evt = EventLoop::new();
    let window_builder = WindowBuilder::new()
        .with_title("Test")
        .with_fullscreen(None);
    let serialization_context = Arc::new(SerializationContext::new());
    let mut engine = Engine::new(EngineInitParams {
        window_builder,
        resource_manager: ResourceManager::new(serialization_context.clone()),
        serialization_context,
        events_loop: &evt,
        vsync: false,
    })
        .unwrap();
}
```

## Serialization

Engine and ResourceManager both are non-serializable anymore. It changes approach of creating save files in games.
Previously you used something like this (following code snippets are modified versions of `save_load` example):

```rust
const SAVE_FILE: &str = "save.bin";

fn save(game: &mut Game) {
    let mut visitor = Visitor::new();

    game.engine.visit("Engine", visitor)?; // This no longer works
    game.game_scene.visit("GameScene", visitor)?;

    visitor.save_binary(Path::new(SAVE_FILE)).unwrap();
}

fn load(game: &mut Game) {
    if Path::new(SAVE_FILE).exists() {
        if let Some(game_scene) = game.game_scene.take() {
            game.engine.scenes.remove(game_scene.scene);
        }

        let mut visitor = block_on(Visitor::load_binary(SAVE_FILE)).unwrap();

        game.engine.visit("Engine", visitor)?; // This no longer works
        game.game_scene.visit("GameScene", visitor)?;
    }
}
```

However, on practice this approach could lead to some undesirable side effects. The main problem with the old
approach is that when you serialize the engine, it serializes all scenes you have. This fact is more or less
ok if you have only one scene, but if you have two and more scenes (for example one for menu and one for
game level) it writes/reads redundant data. The second problem is that you cannot load saved games asynchronously
using the old approach, because it takes mutable access of the engine and prevents you from off-threading work.

The new approach is much more flexible and do not have such issues, instead of saving the entire state of the
engine, you just save and load only what you actually need:

```rust
const SAVE_FILE: &str = "save.bin";

fn save(game: &mut Game) {
    if let Some(game_scene) = game.game_scene.as_mut() {
        let mut visitor = Visitor::new();

        // Serialize game scene first.
        game.engine.scenes[game_scene.scene]
            .save("Scene", &mut visitor)
            .unwrap();
        // Then serialize the game scene.
        game_scene.visit("GameScene", &mut visitor).unwrap();

        // And call save method to write everything to disk.
        visitor.save_binary(Path::new(SAVE_FILE)).unwrap();
    }
}

// Notice that load is now async.
async fn load(game: &mut Game) {
    // Try to load saved game.
    if Path::new(SAVE_FILE).exists() {
        // Remove current scene first.
        if let Some(game_scene) = game.game_scene.take() {
            game.engine.scenes.remove(game_scene.scene);
        }

        let mut visitor = Visitor::load_binary(SAVE_FILE).await.unwrap();

        let scene = SceneLoader::load("Scene", &mut visitor)
            .unwrap()
            .finish(game.engine.resource_manager.clone())
            .await;

        let mut game_scene = GameScene::default();
        game_scene.visit("GameScene", &mut visitor).unwrap();

        game_scene.scene = game.engine.scenes.add(scene);
        game.game_scene = Some(game_scene);
    }
}
```

As you can see in the new approach you save your scene and some level data, and on load - you load the scene, add
it to the engine as usual and load level's data. The new approach is a bit more verbose, but it is much more
flexible.

# 0.24

## Breaking changes and migration guide

There are lots of breaking changes in this version, however all of them mostly related to the code and scenes made in
previous version _should_ still be loadable.

### Convert old scenes to new format

At first, install the rusty-editor from crates.io and run it:

```shell
cargo install rusty-editor
rusty-editor
```

And then just re-save your scenes one-by-one. After this all your scenes will be converted to the newest version.
Keep in mind that the editor from GitHub repo (0.25+) is not longer have backward compatibility/conversion code!

### 2D scenes

2D scene were completely removed and almost every 2D node were removed, there is only one "2D" node left - Rectangle.
2D now implemented in 3D scenes, you have to use orthographic camera for that. There is no migration guide for 2D scenes
because 2D had rudimentary support, and I highly doubt that there is any project that uses 2D of the engine.

## Resource management

Resource manager has changed its API and gained some useful features that should save you some time.

`request_texture` now accepts only one argument - path to texture, second argument was used to pass
`TextureImportOptions`. Import options now should be located in a separate options file. For example, you have a
`foo.jpg` texture and you want to change its import options (compression, wrapping modes, mip maps, etc.). To do this
you should create `foo.jpg.options` file in the same directory near your file with following content (each field is
optional):

```text
(
    minification_filter: LinearMipMapLinear,
    magnification_filter: Linear,
    s_wrap_mode: Repeat,
    t_wrap_mode: Repeat,
    anisotropy: 16,
    compression: NoCompression,
)
```

The engine will read this file when you'll call `request_texture` and it will apply the options on the first load.
This file is not mandatory, you can always set global import defaults in resource manage by calling
`set_texture_import_options`.

`request_model` have the same changes, there is only one argument and import options were moved to options file:

```text
(
    material_search_options: RecursiveUp
)
```

Again, all fields aren't mandatory and the entire file can be omitted, global import defaults can be set by calling
`set_model_import_options`.

### Physics

Old physics was replaced with new scene nodes: RigidBody, Collider, Joint. Old scenes will be automatically converted
on load, you should convert your scenes as soon as possible using the editor (open your scene and save it, that will
do the conversion).

Now there are two ways of adding a rigid body to a scene node:

- If you want your object to have a rigid body (for example a crate with box rigid body), your object must be
  **child** object of a rigid body. Graphically it can be represented like this:

```text
- Rigid Body
  - Crate3DModel
  - Cuboid Collider     
```

- If you want your object to have a rigid body that should move together with your object (to simulate hit boxes for
  example), then rigid body must be child object of your object. Additionally it should be marked as `Kinematic`,
  otherwise it will be affected by simulation (simply speaking it will fall on ground). Graphically it can be
  represented like this:

```text
- Limb
  - Rigid Body
     - Capsule Collider
```

#### Migration

This section will help you to migrate to new physics.

##### Rigid bodies

Rigid body and colliders now can be created like so:

```rust
use fyrox_impl::{
    core::{algebra::Vector3, pool::Handle},
    scene::{
        base::BaseBuilder,
        collider::{ColliderBuilder, ColliderShape},
        node::Node,
        rigidbody::RigidBodyBuilder,
        transform::TransformBuilder,
        Scene,
    },
};

fn create_capsule_rigid_body(scene: &mut Scene) -> Handle<Node> {
    RigidBodyBuilder::new(
        BaseBuilder::new()
            .with_local_transform(
                // To position, rotate rigid body you should use engine's transform.
                TransformBuilder::new()
                    .with_local_position(Vector3::new(1.0, 2.0, 3.0))
                    .build(),
            )
            .with_children(&[
                // It is very important to add at least one child collider node, otherwise rigid
                // body will not do collision response.
                ColliderBuilder::new(
                    BaseBuilder::new().with_local_transform(
                        // Colliders can have relative position to their parent rigid bodies.
                        TransformBuilder::new()
                            .with_local_position(Vector3::new(0.0, 0.5, 0.0))
                            .build(),
                    ),
                )
                    // Rest of properties can be set almost as before.
                    .with_friction(0.2)
                    .with_restitution(0.1)
                    .with_shape(ColliderShape::capsule_y(0.5, 0.2))
                    .build(&mut scene.graph),
            ]),
    )
        // Rest of properties can be set almost as before.
        .with_mass(2.0)
        .with_ang_damping(0.1)
        .with_lin_vel(Vector3::new(2.0, 1.0, 3.0))
        .with_ang_vel(Vector3::new(0.1, 0.1, 0.1))
        .build(&mut scene.graph)
}
```

##### Joints

Joints can be created in a similar way:

```rust
fn create_ball_joint(scene: &mut Scene) -> Handle<Node> {
    JointBuilder::new(BaseBuilder::new())
        .with_params(JointParams::BallJoint(BallJoint {
            local_anchor1: Vector3::new(1.0, 0.0, 0.0),
            local_anchor2: Vector3::new(-1.0, 0.0, 0.0),
            limits_local_axis1: Vector3::new(1.0, 0.0, 0.0),
            limits_local_axis2: Vector3::new(1.0, 0.0, 0.0),
            limits_enabled: true,
            limits_angle: 45.0,
        }))
        .with_body1(create_capsule_rigid_body(scene))
        .with_body2(create_capsule_rigid_body(scene))
        .build(&mut scene.graph)
}
```

##### Raycasting

Raycasting located in `scene.graph.physics`, there were almost no changes to it, except now it returns handles to
scene nodes instead of raw collider handles.

##### Contact info

Contact info can now be queried from the collider node itself, via `contacts()` method.

```rust
fn query_contacts(collider: Handle<Node>, graph: &Graph) -> impl Iterator<Item=ContactPair> {
    graph[collider].as_collider().contacts(&graph.physics)
}
```
