Creating a Shape Node from an Array of Points
Create jagged or smooth shapes from the same array of points.
SKShapeNode object can be initialized with an array of points describing a path. The
init(splinePoints:count:) method can smoothly interpolate between these points to create a curve rather than the series of straight lines created by
init(points:count:). The following code shows how to create two shape nodes using the same array of points for both initializers.
var points = [CGPoint(x: 0, y: 0), CGPoint(x: 100, y: 100), CGPoint(x: 200, y: -50), CGPoint(x: 300, y: 30), CGPoint(x: 400, y: 20)] let linearShapeNode = SKShapeNode(points: &points, count: points.count) let splineShapeNode = SKShapeNode(splinePoints: &points, count: points.count)
The following image shows linearShapeNode in blue and splineShapeNode in red.
