Automatically initializes a state in the app.
# Parameters
- `plugin = PluginType` - Required unless the `default_plugin` feature is enabled and `#[auto_plugin(default_plugin)]` is in scope. Specifies which plugin should initialize this state.
- `after_build` - Optional. Injects this macro's tokens at the end of the plugin build instead of the start.
- `generics(T1, T2, ...)` - Optional. Specifies concrete types for generic parameters.
When provided, the states will be registered with these specific generic parameters.
Note: Clippy will complain if you have duplicate generic type names. For those you can use named generics: `generics(A = ..., B = ...)`.
- `derive` | `derive(Debug, Default, ..)` - Optional. Specifies that the macro should handle deriving `States`.
Passes through any additional derives listed.
When enabled, `States` include these additional derives:
- `Debug`
- `Default`
- `Copy`
- `Clone`
- `PartialEq`
- `Eq`
- `Hash`
- `reflect` | `reflect(Debug, Default, ..)` - Optional. Specifies that the macro should handle emitting the single `#[reflect(...)]`.
Passes through any additional reflects listed.
If enabled in tandem with `derive` it also includes `#[derive(Reflect)]`
- `register` - Enables type registration for the `States`
Same as having `#[auto_register_type]` and `#[auto_register_state_type]`
- `init` - Initializes the `States` with default values
Same as having `#[auto_init_state]`
// Debug, Default, Copy, Clone, PartialEq, Eq, Hash
# Example
```rust
use bevy::prelude::*;
use bevy_auto_plugin::prelude::*;
#[derive(AutoPlugin)]
#[auto_plugin(impl_plugin_trait)]
struct MyPlugin;
#[auto_states(plugin = MyPlugin, derive, reflect, register, init)]
enum FooState {
#[default]
Start,
End,
}
```
