Migrating from V0 to V1
======

AnimatorAsCode V1 introduces the following main breaking changes:
- VRChat Avatars is now an optional dependency. AnimatorAsCode can now be used in non-VRChat projects.
  - All VRChat-related functions have been split between two classes of extension methods.
- You are now encouraged to use a non-destructive workflow by generating an animator controller asset without relying on an existing animator controller asset.
  - VRChat methods that use a destructive workflow, such as `AacFlBase.CreateMainFxLayer()` are located on their own class of extension methods.  

## Assembly definition

If you use assembly definitions, change the assembly reference from `AnimatorAsCodeFramework` to the following:
- `AnimatorAsCodeFramework.V1` in all cases. 
- `AnimatorAsCodeFramework.V1.VRC` if you depend on VRChat.
- `AnimatorAsCodeFramework.V1.VRCDestructiveWorkflow` also if you need to edit the playable layers of the avatar directly.
  - *Consider switching to a non-destructive workflow using VRCFury or Modular Avatar! See below.*
 
## Code changes

### Code

- Change `AacV0` to `AacV1`
- Change `using AnimatorAsCode.V0;` to `using AnimatorAsCode.V1;`
- If your project depends on VRChat, you will need to use extension methods.
  - Add `using AnimatorAsCode.V1.VRC;` in your class imports to use the VRChat extension methods.
    - The extension methods are contained within the class `AnimatorAsCode.V1.VRC.AacVRCExtensions`.
  - Add `using AnimatorAsCode.V1.VRC;` in your class imports to use the extension methods.
    - The extension methods are contained within the class `AnimatorAsCode.V1.VRCDestructiveWorkflow.AacVRCDestructiveWorkflowExtensions`

# TODO

- TODO: Check TrackingElement being renamed to AacAv3.Av3TrackingElement

### AacConfiguration

Since `AacConfiguration` no longer contains the avatar descriptor, you will need to use the extension method `AacConfiguration.WithAvatarDescriptor(VRCAvatarDescriptor)` to define the avatar in the configuration.

For example:

```csharp
using AnimatorAsCode.V1;
using AnimatorAsCode.V1.VRCDestructiveWorkflow;
// ...

AacV1.Create(new AacConfiguration
{
    SystemName = systemName,
    AnimatorRoot = avatar.transform,
    DefaultValueRoot = avatar.transform,
    AssetContainer = assetContainer,
    AssetKey = assetKey,
    DefaultsProvider = new AacDefaultsProvider(writeDefaults: options.WriteDefaults)
}.WithAvatarDescriptor(avatar)); // The avatar descriptor is now defined by invoking an extension method.
```

# Non-destructive workflow

Animator As Code V1 encourages the use of a non-destructive workflow.

Here's a quick example:
