Unity調用PC攝像頭

轉載於Unity3d聖典裏面，具體哪位大俠寫的我忘咯。

using UnityEngine;
using System.Collections;

public class CameraTest : MonoBehaviour {

    public string deviceName;
    WebCamTexture tex;
    // Use this for initialization
    IEnumerator Start()
    {
        //獲取受權
        yield return Application.RequestUserAuthorization(UserAuthorization.WebCam);
        if (Application.HasUserAuthorization(UserAuthorization.WebCam))
        {
            WebCamDevice[] devices = WebCamTexture.devices;
            deviceName = devices[0].name;
            tex = new WebCamTexture(deviceName, 400, 300, 12);
            renderer.material.mainTexture = tex;
            tex.Play();
        }
        else
        {
        }
    }
}

綁定在一個帶有Render組件的物體上就好了。
