Deploy Stage Once Script now broken

By jasonsone on Tue, 03/20/2018 - 14:58

I loaded up Unity today and it prompted me to upgrade to Vuforia 7.1.27. Now, the DeployStageOnce script found at https://library.vuforia.com/articles/Solution/ground-plane-guide.html no longer works. I'm getting two compile errors:

DeployStageOnce.cs(49,51): error CS1061: Type `Vuforia.Anchor' does not contain a definition for `transform' and no extension method `transform' of type `Vuforia.Anchor' could be found. Are you missing an assembly reference?

DeployStageOnce.cs(60,27): error CS0029: Cannot implicitly convert type `Vuforia.Anchor' to `UnityEngine.GameObject'

I have updated Vuforia Ground Plane from the asset store to 7.1.30 and Vuforia Core Samples from the asset store to 7.1.30. I have also restarted Unity. I'm currently running Unity 2018.1.0b11.

Any idea what's going on?

Can confirm. Same problem

Can confirm. Same problem here. Any answers?

I'm on Unity 2017.3 and Vuforia 7.0.36 and it's not working for me anymore on device either although I don't get compilation errors during build.
Help lol

Hey there.

Hey there.
I made a work around for this since I am using the deploy stage once script to do quite a bit more than just lay a stage out - but I have an official response and my work around for you.

The official:

Hi Joey,

Thanks for this.

When you say "Parent the stage to the new GameObject like you would have the anchor before"

Do you mean before running the app, create a new GameObject in the Hierarchy and then parent the "Ground Plane Stage" object to it?

But what about those of us on

But what about those of us on 2017?

Same question. Have they updated Vuforia framework on pre Unity 2018 versions but left out the UI function to check/uncheck "Duplicate Stage"?

I am struggling with a

I am struggling with a similar issue. I am using Unity 2018.1.6f1 with Vuforia v 7.2.20. I want to place a grid plane once then use my own script that uses ray casting to place objects on my grid plane without the use of Vuforia's PositionContentAtPlaneAnchor method.

Have you tried to disable the

Have you tried to disable the AnchorInputListener Behaviour? I am pretty sure this is what is capturing your input. In general, though - you should be able to disable the entire PlaneFinder GameObject if you are happy with the location of your Ground Plane Stage.

This is a bit confusing! Does

This is a bit confusing! Does this mean that there is no way for the user to re-track the plane to re-place the deploy plane once?

I've found the solution

I've found the solution yesterday.

I added the component "AnchorBehaviour" on my augmented visual. You have to configure this component with the Anchor.

Pseudo code:

Vector3 screenPos = Camera.main.WorldToScreenPoint(model.transform.position);

Thanks,
