Visual Feedback around Cursor

HoloFan

Hey,

I am trying to show visual feedback after voice commands around the cursor.
I use the keyword manager from the HoloToolkit to pick up the commands.

I have a working solution, but I am not sure whether there might be a better i.e. more efficient method.

I wrote the "SendFeedback.cs"-Script to handle the feedback. This script is attached to a GameObject which also has a script to take action when the keyword was recognized - let's call this script "FeedbackTest.cs".

In Unity I attache a Prefab to the "FeedbackAsset" property and the cursor to the "FeedbackParent"-Property.

Is this a good concept to handle visual feedback? Or is there a simpler way which I have missed?

Thanks in advanced.

SendFeedback.cs
using UnityEngine;

        public class SendFeedback : MonoBehaviour
        {

            [Tooltip("Feedack Prefab Asset.")]
            public GameObject FeedbackAsset;
            private GameObject feedbackGameObject;

            [Tooltip("Prefab to Parent the Prefab")]
            public GameObject FeedbackParent;

            [Tooltip("Time to display the feedback Asset.")]
            public float DisplayTime = 2.0f;


            delegate void FeedbackDelegate();
            FeedbackDelegate feedbackDelegate;

            private void Awake()
            {
                if (FeedbackAsset != null && FeedbackParent != null)
                {
                    feedbackGameObject = GameObject.Instantiate(FeedbackAsset);
                    feedbackGameObject.transform.parent = FeedbackParent.transform;
                    feedbackGameObject.SetActive(false);

                    feedbackDelegate = InvokeFeedback;
                }
                else
                {
                    Debug.Log("No Feedback Asset and/or Feedback parent assigned!");
                    Destroy(this);
                }
            }

            public void SendFeedbackInvoke()
            {
                feedbackDelegate();
            }

            private void InvokeFeedback()
            {
                ShowFeedback();
                Invoke("HideFeedback", DisplayTime);
            }

            private void ShowFeedback()
            {
                if (feedbackGameObject != null)
                {
                    feedbackGameObject.SetActive(true);
                }
            }

            private void HideFeedback()
            {
                if (feedbackGameObject != null)
                {
                    feedbackGameObject.SetActive(false);
                }
            }

        }

SendFeedback.cs

using UnityEngine;

public class FeedbackTest : MonoBehaviour {

    private SendFeedback sendFeedback;

    private void Awake()
    {
        sendFeedback = GetComponent<SendFeedback>();
    }

    public void KeywordHeard()
    {
        sendFeedback.SendFeedbackInvoke();

        // Do other stuff here...

    }
}

I guess you could nest some particle effect or w/e inside the cursor state's visual container, then play those contextually as needed. I wrote a little post about custom cursors here, if you're using the HoloToolkit's cursor in the same fashion then I think this would work.

Thank you for your answer. It sounds quit good. I like the idea of creating new states and assigning custom visuals for these states.
But I think I will use my method as I don't want to keep track of all scripts sending feedback in my Cursor-GameObject.
