Voice to show/hide cursor?

clafayette

I'm using the HL with a model built in layers, like an onion. I was able to borrow the cursor from Origami tutorial along with associated scripts to move the model and show/hide each of five layers, using voice commands. But the same script doesn't show / hide the cursor. The cursor is in root of hierarchy in Unity 5 as in the Origami setup. Can anyone suggest what needs to change to show/hide the cursor?

The same script works for layers, but not for the cursor:

Code is:

keywords.Add("Show cursor", () =>
{
this.BroadcastMessage("OnShowCursor");
});

    keywords.Add("Hide cursor", () =>
    {
        this.BroadcastMessage("OnHideCursor");
    });

To show/hide I'm using:

public void OnShowCursor()
{
rend = GetComponent();
rend.enabled = true;
}

public void OnHideCursor()
{
    rend = GetComponent<Renderer>();
    rend.enabled = false;
}

@clafayette if you also borrowed the WorldCursor.cs script from the origami project, you will probably want to add you OnShowCursor and OnHideCursor handlers to that script.

They should set a variable inside the handlers that you would then work into the conditional logic inside the WorldCursor "Update" routine logic that would only execute the meshRenderer.enabled = true; section when your cursor is being shown.

For example something like the following untested code might work:

using UnityEngine;

public class WorldCursor : MonoBehaviour
{
    private MeshRenderer meshRenderer;

    private bool ShowCursor;

    void Start()
    {
        // Grab the mesh renderer that's on the same object as this script.
        meshRenderer = this.gameObject.GetComponentInChildren<MeshRenderer>();
    }

public void OnShowCursor()
 {
 ShowCursor = true;
 }

public void OnHideCursor()
{
   ShowCursor = false;
}

    // Update is called once per frame
    void Update()
    {
        // Do a raycast into the world based on the user's
        // head position and orientation.
        var headPosition = Camera.main.transform.position;
        var gazeDirection = Camera.main.transform.forward;

        RaycastHit hitInfo;

        if (Physics.Raycast(headPosition, gazeDirection, out hitInfo) && ShowCursor == true)
        {
            // If the raycast hit a hologram...
            // Display the cursor mesh.
            meshRenderer.enabled = true;

            // Move the cursor to the point where the raycast hit.
            this.transform.position = hitInfo.point;

            // Rotate the cursor to hug the surface of the hologram.
            this.transform.rotation = Quaternion.FromToRotation(Vector3.up, hitInfo.normal);
        }
        else
        {
            // If the raycast did not hit a hologram, hide the cursor mesh.
            meshRenderer.enabled = false;
        }
    }
}

Thanks HoloSheep, this worked nicely! I added ShowCursor = true; to WorldCursor, above, to show the cursor on start.

void Start()
{
    // Grab the mesh renderer that's on the same object as this script.
    meshRenderer = this.gameObject.GetComponentInChildren<MeshRenderer>();
    ShowCursor = true;
