## PassHasKeyword(Shader, PassIdentifier, LocalKeyword)

Checks whether a local shader keyword is valid for a Pass within a particular shader.

```csharp
public static bool PassHasKeyword(Shader s, in PassIdentifier passIdentifier, in LocalKeyword keyword)
```

### Parameters

**** (\[Shader]\(/engine/6000.3/script-reference/unityengine/shader)): The shader the Pass belongs to.**** (\[PassIdentifier]\(/engine/6000.3/script-reference/unityengine/rendering/passidentifier)): The identifier of a Pass within the given shader.**** (\[LocalKeyword]\(/engine/6000.3/script-reference/unityengine/rendering/localkeyword)): The local shader keyword to check.

### Returns

| Type                                                          | Description                                                                                                                                                                                                                                                                            |
| ------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | Returns true if the keyword is valid for the given Pass. Otherwise, returns false. If the [PassIdentifier](/engine/6000.3/script-reference/unityengine/rendering/passidentifier.md) you use is invalid, this function returns false and Unity displays an error in the Console window. |

```

### Parameters

### Returns

| Type                                                          | Description                                                                                                                                                                                                                                                                                                |
| ------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | Returns true if the keyword is valid for the given shader stage of the Pass. Otherwise, returns false. If the [PassIdentifier](/engine/6000.3/script-reference/unityengine/rendering/passidentifier.md) you use is invalid, this function returns false and Unity displays an error in the Console window. |

### Returns

| Type                                                          | Description                                                                                                                                                                                                                                                                                                                                     |

| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | Returns true if the keyword is valid for the given shader stage of the Pass for the given ShaderCompilerPlatform. Otherwise, returns false. If the [PassIdentifier](/engine/6000.3/script-reference/unityengine/rendering/passidentifier.md) you use is invalid, this function returns false and Unity displays an error in the Console window. |

### Remarks

Some shader compiler platforms combine several shader stages in one. This method overload ensures that correct data is returned for all shader compiler platforms.
