Please help..
It's just a newbie who is just getting into the unity development. I thought about implementing a webcam and completed it. To get to the stage, we use our webcam to sprinkle hand movements in real time and react in seconds.
Delaying was successful![alt text][1], but no camera rendering keeps popping up.
The error code is
UnassignedReferenceException: The variable renderCamera of DelayedCamera has not been assigned.
You probably need to assign the renderCamera variable of the DelayedCamera script in the inspector.
DelayedCamera.Awake () (at Assets/Scenes/DelayedCamera.cs:107)
The whole code is
using UnityEngine;
using System.Collections;
public class DelayedCamera : MonoBehaviour
{
public struct Frame
{
///
/// The texture representing the frame
///
private Texture2D texture;
///
/// The time (in seconds) the frame has been captured at
///
private float recordedTime;
///
/// Captures a new frame using the given render texture
///
/// The render texture this frame must be captured from
public void CaptureFrom( RenderTexture renderTexture )
{
RenderTexture.active = renderTexture;
// Create a new texture if none have been created yet in the given array index
if ( texture == null )
texture = new Texture2D( renderTexture.width, renderTexture.height );
// Save what the camera sees into the texture
texture.ReadPixels( new Rect( 0, 0, renderTexture.width, renderTexture.height ), 0, 0 );
texture.Apply();
recordedTime = Time.time;
RenderTexture.active = null;
}
///

///
/// The time

}

private int bufferSize = 256;
///

private int frameIndex;
private void Awake()
{
frames = new Frame[bufferSize];
// Change the depth value from 24 to 16 may improve performances. And try to specify an image format with better compression.
renderTexture = new RenderTexture( Screen.width, Screen.height, 24 );
renderCamera.targetTexture = renderTexture;
StartCoroutine( Render() );
}
