I have the following code:



 private func updateNodePosition()

if updateNodes

locationUpdate += 1

SCNTransaction.begin()

SCNTransaction.animationDuration = 1

if updateLocations.count > 0

myLocation = CLLocation.bestLocationEstimate(locations:
updateLocations)

for node in nodes

print("@7")

let translation = Matrix.transformMatrix(for:

matrix_identity_float4x4, originLocation: myLocation, location: node.location)

let position = SCNVector3.positionForNode(transform:
translation)

let distance = node.location.distance(from: myLocation)

DispatchQueue.main.async

let scale = 100 / Float(distance)

node.scale = SCNVector3(x: scale, y: scale, z: scale)

node.position = position

node.anchor = ARAnchor(transform: translation)

print("@8")


for pathN in pathNodes

print("@9")

let translation = Matrix.transformMatrix(for:

matrix_identity_float4x4, originLocation: myLocation,

location: pathN.location)
let position = SCNVector3.positionForNode(transform:
translation)

let distance = pathN.location.distance(from: myLocation)

DispatchQueue.main.async

let scale = 100 / Float(distance)

pathN.scale = SCNVector3(x: scale, y: scale, z: scale)

pathN.position = position

pathN.anchor = ARAnchor(transform: translation)

print("@10")

//add vectors to path

pathPoints.append(position)


SCNTransaction.commit()

path()

mapView.addOverlay(myRoute.polyline)



It basically lays out a path from my current location to my destination. However, the issue I am having is the the path moves along with me. It does not stay anchored in one place. I am not too sure how to keep it fixed in one place for me to follow the path like you can on Google or Apple Maps. Any help on this would be greatly appreciated and please let me know if there is any way I can provide more clarity.
