Enable and disable Renderer or Canvas not working

Every 5 seconds I need to take a photo and display it in the world. That part is working fine.
Once a photo is taken it need to disappear 1 second after. That's where I'm stuck.
I've gotten it to disappear but then I cant get the new picture to reappear when its function is called again.

Any ideas?

I've tried:
m_CanvasRenderer.enabled = false;
m_CanvasRenderer.enabled = true;
m_Canvas = null;
m_Canvas.setActive(false);
m_Canvas.setActive(true);

Code (CSharp):

1. public class PhotoCaptureExample : MonoBehaviour
2. {
3.     GestureRecognizer m_GestureRecognizer;
4.     GameObject m_Canvas = null;
5.     Renderer m_CanvasRenderer = null;
6.     PhotoCapture m_PhotoCaptureObj;
7.     CameraParameters m_CameraParameters;
8.     bool m_CapturingPhoto = false;
9.     Texture2D m_Texture = null;
10.  
11.     void Start()
12.     {
13.         Initialize();
14.         InvokeRepeating("TakePhoto", 5.0f, 5.0f);
15.         //StartCoroutine(TakePhoto());
16.     }
17.  
18. void TakePhoto()
19.     {
20.         if (m_CapturingPhoto)
21.         {
22.             return;
23.         }
24.         m_CapturingPhoto = true;
25.         m_PhotoCaptureObj.TakePhotoAsync(OnPhotoCaptured);
26.     }
27.  
28.     void OnPhotoCaptured(PhotoCapture.PhotoCaptureResult result, PhotoCaptureFrame photoCaptureFrame)
29.     {
30.        // m_CanvasRenderer.enabled = true;
31.  
32.         if (m_Canvas == null)
33.         {
34.  
35.             m_Canvas = GameObject.CreatePrimitive(PrimitiveType.Quad);
36.             m_Canvas.name = "PhotoCaptureCanvas";
37.             m_CanvasRenderer = m_Canvas.GetComponent<Renderer>() as Renderer;
38.             m_CanvasRenderer.material = new Material(Shader.Find("AR/HolographicImageBlend"));
39.         }
40.  
41.         Matrix4x4 cameraToWorldMatrix;
42.         photoCaptureFrame.TryGetCameraToWorldMatrix(out cameraToWorldMatrix);
43.         Matrix4x4 worldToCameraMatrix = cameraToWorldMatrix.inverse;
44.  
45.         Matrix4x4 projectionMatrix;
46.         photoCaptureFrame.TryGetProjectionMatrix(out projectionMatrix);
47.  
48.         photoCaptureFrame.UploadImageDataToTexture(m_Texture);
49.         m_Texture.wrapMode = TextureWrapMode.Clamp;
50.  
51.         m_CanvasRenderer.sharedMaterial.SetTexture("_MainTex", m_Texture);
52.         m_CanvasRenderer.sharedMaterial.SetMatrix("_WorldToCameraMatrix", worldToCameraMatrix);
53.         m_CanvasRenderer.sharedMaterial.SetMatrix("_CameraProjectionMatrix", projectionMatrix);
54.         m_CanvasRenderer.sharedMaterial.SetFloat("_VignetteScale", 1.0f);
55.  
56.         // Position the canvas object slightly in front
57.         // of the real world web camera.
58.         Vector3 position = cameraToWorldMatrix.GetColumn(3) - cameraToWorldMatrix.GetColumn(2);
59.  
60.         // Rotate the canvas object so that it faces the user.
61.         Quaternion rotation = Quaternion.LookRotation(-cameraToWorldMatrix.GetColumn(2), cameraToWorldMatrix.GetColumn(1));
62.  
63.         m_Canvas.transform.position = position;
64.         m_Canvas.transform.rotation = rotation;
65.  
66.         m_CapturingPhoto = false;
67.  
68.         float counter = 0; float target = 1;
69.         while (counter < target)
70.         {
71.             counter += Time.deltaTime;
72.         }
73.         // m_CanvasRenderer.enabled = false;
74.      
75.     }
76. }

 

First off, I admit though while I grasp the concept of most of your code, it's over my head.
However, the ability to turn something on/off , visibility-wise should be pretty straight-forward.
Whatever you turned off (renderer/canvas), after the canvas check against null .. turn it back on.
One note, though, is that you're forcing a spin loop waiting for 1 second in your script. That's a different issue, though.
If you turn on the renderer manually in the inspector on the second time through, is the photo there just invisible?

 

Get the <Canvas> component and just toggle that instead of the actual gameObject.

 

Just a note, when I was reading this post, it appeared as though he was creating a unique "canvas" improv.
I could be wrong or misunderstanding it, but his canvas is a quad..

 

You are correct.

My bad, early mornings...

 

All good.. Confused me, too. I sometimes use 'general' names like that, but other times I can see how un-nice it can be when you go back/others read it

 

I'm working in the hololens so I cant turn the renderer on manually in the inspector while running.
I thought it would be strait forward to turning something invisible then visible again.

 

Should be straight forward. Hope you figure it out.
