# init()

Initializes a noise map with a constant noise value of zero throughout.

## Declaration

```swift
convenience init()
```

## Return Value

Return Value A new noise map object.

## Discussion

Discussion This convenience initializer is equivalent to creating a GKNoise object from GKConstantNoiseSource output with a constant value of zero, then using the init(_:) initializer to create a noise map from the result.
