# calculateAccumulatedFrame()

Returns a rectangle in the parent’s coordinate system that contains the position and size of itself and all child nodes.

## Declaration

```swift
func calculateAccumulatedFrame() -> CGRect
```

## Discussion

Discussion The frame takes into the account the cumulative effect of the xScale, yScale, and zRotation properties of each node in the subtree. Listing 1 shows, in Swift, how calculateAccumulatedFrame() can be used display the bounding box of a shape node. The child node, although smaller than its parent, is rotated by 30° so that its bounds extend beyond its parent’s bounds. After childNode has been added to parentNode, a further shape node, boundingBoxNode, is created with its size based on the accumulated frame of parentNode. Listing 1. Displaying the accumulated frame of a shape node let parentNode = SKShapeNode(rectOf: CGSize(width: 500, height: 500)) parentNode.lineWidth = 2 parentNode.strokeColor = .blue parentNode.fillColor = .clear       let childNode = SKShapeNode(rectOf: CGSize(width: 400, height: 400)) childNode.strokeColor = .red childNode.fillColor = .clear childNode.zRotation = -CGFloat.pi / 6 // pi / 6 = 30°       parentNode.addChild(childNode)       let boundingBoxNode = SKShapeNode(rectOf: parentNode.calculateAccumulatedFrame().size) boundingBoxNode.lineWidth = 1 boundingBoxNode.strokeColor = .black boundingBoxNode.fillColor = .clear boundingBoxNode.path = boundingBoxNode.path?.copy(dashingWithPhase: 0,                                                   lengths: [10,10])       parentNode.addChild(boundingBoxNode) The figure below shows the result of Listing 1 with parentNode rendered in blue, childNode rendered in red and the boundingBoxNode rendered with a dashed line.
