Detecting Webcam in Unity3D using C#

This is a basic tutorial explains how to detect webcam in Unity3D.

• Create a new project in Unity3D
• Create a new plane in unity3D under GameObject >> 3D Object >> Plane
• Set the Y rotation of plane to 180.
• Create a new folder named "Scripts" under assets.
• Create a new C# file under the Scripts folder and name it as DetectWebcam
• Drag the script over plane / Attach the script on the newly created plane
  
  
  
• Double click the DetectWebcam script file to launch Monodevelop/ Visual studio.
• Copy & paste the below code.

using UnityEngine;

using System.Collections;

public class DetectWebcam : MonoBehaviour

{

    void Start() 

    {

        WebCamDevice[] devices = WebCamTexture.devices;

        for( var i = 0 ; i < devices.Length ; i++ )

        {

            Debug.Log(devices[i].name);// Gets the list of available devices and prints its name

        }

        string deviceName = WebCamTexture.devices[0].name;

        WebCamTexture newTexture = new WebCamTexture(deviceName, 640, 360, 30);

        newTexture.Play();

        gameObject.GetComponent<Renderer>().material.mainTexture = newTexture;

            

    }

}

• Save the code and play the scene in Unity3D.
  
• That's it
