# `GSPath nextOncurveNodeFromIndex:`

*Instance Method*

The next on-curve node after an index.

## Declaration

```swift
func nextOncurveNode(from index: Int) -> GSNode?
```

```objc
- (GSNode *) nextOncurveNodeFromIndex:(NSInteger) index;
```

```python
nextOncurveNodeFromIndex_(index: int) -> GSNode
```

## Discussion

For a closed path, navigation wraps around the path. For an open path, returns `nil` when no next on-curve node exists. For a path consisting solely of off-curve nodes, returns `nil`.
