# init(edgeChainFrom:)

Creates an edge chain from a path.

## Declaration

```swift
init(edgeChainFrom path: CGPath)
```

## Parameters

- `path`: A Core Graphics path. The points are specified relative to the owning node’s origin. The path must not intersect itself.

## Mentioned in

Shaping a Physics Body to Match a Node’s Graphics

## Return Value

Return Value A new edge-based physics body.

## Discussion

Discussion An edge has no volume or mass and is always treated as if the isDynamic property is equal to false. Edges may only collide with volume-based physics bodies.
