# Suggestion attributes

## Custom suggestion attributes

Most parameter types such as `enum`, `bool`, `Color` and derivatives from `UnityEngine.Object` already comes with suggestions. However, it's also possible to define your own custom suggestions that you can specify on individual parameters.

To define your own suggestions, make a new class that inherits from `SuggestionAttribute`:

```csharp
public class PositionAttribute : SuggestionAttribute
{
    public override IEnumerable<string> Get()
    {
        string[] positions = { "(0,0,0)", "(20,10,20)", "(5,100,5)" };
        return positions;
    }
}
```

Then to see the suggestions on a parameter, put the attribute on the parameter in the method.

```csharp
public class Player : MonoBehaviour
{
    [Command]
    public void Teleport([Position] Vector3 position)
    {
        transform.position = position;
    }
}
```

## Built-in suggestion attributes[​](https://ghostlike.dk/docs/suggestions#built-in-suggestion-attributes) <a href="#built-in-suggestion-attributes" id="built-in-suggestion-attributes"></a>

* `[SceneName]` - List of all scenes.
