## Definition

* **Assembly:** UnityEngine.CoreModule

## GetLeadTime\<T>(T)

> **Warning:**
>
> **Deprecated.** GetLeadTime is obsolete. It was used to trigger PlayableBehaviour.PrepareData as part of the now obsolete Playable Delay functionality. Since this deprecation GetLeadTime has no effect and will be removed in a future version. You can emulate this functionality by implementing your own delay mechanism as part of a PlayableBehaviour

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

### Parameters

**** (T): The [Playable](/engine/6000.7/script-reference/unityengine/playables/playable.md) used by this operation.

| ------------------------------------------------------------- | ----------- |
| [float](https://learn.microsoft.com/dotnet/api/system.single) |             |
