# dynamicallyCall(withArguments:)

Returns a new shader by applying the provided argument values to the referenced function.

## Declaration

```swift
func dynamicallyCall(withArguments args: [Shader.Argument]) -> Shader
```

## Discussion

Discussion Typically this subscript is used implicitly via function-call syntax, for example: let shader = ShaderLibrary.default.myFunction(.float(42)) which creates a shader passing the value 42 to the first unbound parameter of myFunction().
