# GetInputCount<U>(U)

> Returns the number of inputs supported by the Playable.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.Playables](/engine/6000.5/script-reference/unityengine/playables.md)
* **Assembly:** UnityEngine.CoreModule

## GetInputCount\<T>(T)

```csharp
public static int GetInputCount<U>(this U playable) where U : struct, IPlayable
```

### Parameters

**** (T): The [Playable](/engine/6000.5/script-reference/unityengine/playables/playable.md) used by this operation.

### Returns

| Type                                                       | Description                          |
| ---------------------------------------------------------- | ------------------------------------ |
| [int](https://learn.microsoft.com/dotnet/api/system.int32) | The count of inputs on the Playable. |

### Remarks

The input count includes slots that aren't connected to anything. This is equivalent to, but much faster than calling GetInputs().Length.

Use this templated extension method on any type that inherits from [IPlayable](/engine/6000.5/script-reference/unityengine/playables/iplayable.md).
