Unity Android前置摄像头

Question

我如何更改此代码以访问前凸轮，当前它向我显示后凸轮？？ 我尝试了一些不同的方法，但似乎没有用。

    if (isLocalPlayer)
    {
        if (this.gameObject.name == "Player 1") {
            WebCamTexture webcamTexture = new WebCamTexture ();
            Player1Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player1Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player1Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
            webcamTexture.Play ();
        } else if (this.gameObject.name == "Player 2") {
            WebCamTexture webcamTexture = new WebCamTexture ();
            Player2Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player2Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player2Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
            webcamTexture.Play ();
        } else if (this.gameObject.name == "Player 3") {
            WebCamTexture webcamTexture = new WebCamTexture ();
            Player3Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player3Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player3Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
            webcamTexture.Play ();
        } else if (this.gameObject.name == "Player 4") {
            WebCamTexture webcamTexture = new WebCamTexture ();
            Player4Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player4Image.GetComponent<RawImage> ().texture = webcamTexture;
            Player4Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
            webcamTexture.Play ();
        } else {
            Debug.Log ("All slots full!");
            GameObject.Destroy (this);
            Network.Disconnect ();
        }


    }

您当前使用默认设备创建WebcamTexture的代码，因为您正在使用不带任何参数的构造函数，该参数传递deviceName的空字符串。

如果查看WebCamTexture文档 ，它将列出可以提供deviceName的构造函数。 现在，您要做的就是：

1. 确定前置摄像头的deviceName 。
2. 创建WebCamTexture对象时，请使用前置摄像头的deviceName 。

您可以查询可用摄像机的设备名称，如下所示：

var webCamDevices = WebCamTexture.devices;
foreach(var camDevice in webCamDevices){ 
    Debug.Log(camDevice.name);
}

另外， WebCamDevice的isFrontFacing属性还将帮助查询您使用的摄像机是否是前置摄像机。 因此，一种简单的方式来确保找到的第一个前置摄像头将用于您的情况：

if (isLocalPlayer)
{
    string frontCamName = null;
    var webCamDevices = WebCamTexture.devices;
    foreach(var camDevice in webCamDevices){ 
        if(camDevice.isFrontFacing){
            frontCamName = camDevice.name;
            break;
        }
    }
    if (this.gameObject.name == "Player 1") {
        WebCamTexture webcamTexture = new WebCamTexture (frontCamName);
        Player1Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player1Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player1Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
        webcamTexture.Play ();
    } else if (this.gameObject.name == "Player 2") {
        WebCamTexture webcamTexture = new WebCamTexture (frontCamName);
        Player2Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player2Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player2Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
        webcamTexture.Play ();
    } else if (this.gameObject.name == "Player 3") {
        WebCamTexture webcamTexture = new WebCamTexture (frontCamName);
        Player3Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player3Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player3Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
        webcamTexture.Play ();
    } else if (this.gameObject.name == "Player 4") {
        WebCamTexture webcamTexture = new WebCamTexture (frontCamName);
        Player4Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player4Image.GetComponent<RawImage> ().texture = webcamTexture;
        Player4Image.GetComponent<RawImage> ().material.mainTexture = webcamTexture;
        webcamTexture.Play ();
    } else {
        Debug.Log ("All slots full!");
        GameObject.Destroy (this);
        Network.Disconnect ();
    }
}

请注意，通过删除break语句，您将使用最后列出的前置摄像头。 同样，将frontCamName设置为私有属性并在Start（）函数中对其进行初始化将是一个好习惯。
