Unity - 在游戏电视机中

Question

我有一些电视机型，比如

和C＃代码

using UnityEngine;
using System.Collections;

public class ClicktoPlayWebMovieClass : MonoBehaviour {

    // Use this for initialization
    void Start () {

    }

    private Vector3 FindBoundCord (int i, GameObject _GameObject){
        /*This is basically where the code starts. It starts out by creating a 
           * bounding box around the target GameObject. 
          It calculates the 8 coordinates forming the bounding box, and 
          returns them all to the for loop.
          Because there are no real method which returns the coordinates 
          from the bounding box I had to create a switch/case which utillized 
          Bounds.center and Bounds.extents.*/

        Bounds _TargetBounds = _GameObject.GetComponent<Renderer>().bounds;
        Vector3 _TargetCenter = _TargetBounds.center;
        Vector3 _TargetExtents = _TargetBounds.extents;


        switch(i){
        case 0:
            return _TargetCenter + new Vector3(_TargetExtents.x, _TargetExtents.y, _TargetExtents.z); 
        case 1:
            return _TargetCenter + new Vector3(_TargetExtents.x, _TargetExtents.y, _TargetExtents.z*-1);
        case 2:
            return _TargetCenter + new Vector3(_TargetExtents.x, _TargetExtents.y*-1, _TargetExtents.z);
        case 3:
            return _TargetCenter + new Vector3(_TargetExtents.x, _TargetExtents.y*-1, _TargetExtents.z*-1);
        case 4:
            return _TargetCenter + new Vector3(_TargetExtents.x*-1, _TargetExtents.y, _TargetExtents.z);
        case 5:
            return _TargetCenter + new Vector3(_TargetExtents.x*-1, _TargetExtents.y, _TargetExtents.z*-1);
        case 6:
            return _TargetCenter + new Vector3(_TargetExtents.x*-1, _TargetExtents.y*-1, _TargetExtents.z);
        case 7:
            return _TargetCenter + new Vector3(_TargetExtents.x*-1, _TargetExtents.y*-1, _TargetExtents.z*-1);
        default:
            return Vector3.zero;
        }

    }

    IEnumerator MyMethod() {
        //Debug.Log("Before Waiting 2 seconds");
        yield return new WaitForSeconds(2);
        //Debug.Log("After Waiting 2 Seconds");
    }

    public string url = "http://becunningandfulloftricks.files.wordpress.com/2013/04/hedgehog_in_the_fog.ogg";

    // Update is called once per frame
    void Update () {


        if (Input.GetMouseButtonDown (0)) {
            Debug.Log("clicked");

                StartCoroutine(MyMethod());
            }

            print("LOADED!!!");

            Vector2 _ObjectScreenCord, _Xmin = new Vector2(Screen.width,0), _Xmax = Vector2.zero, _Ymin = new Vector2(Screen.height,0), _Ymax = Vector2.zero;

            for(int i = 0; i != 8; i++){
                //FindBoundCord() locates the eight coordinates that forms the boundries, followed by converting the coordinates to screen space.
                // The entire script starts in FindBoundCord
                _ObjectScreenCord = Camera.main.WorldToScreenPoint(FindBoundCord(i, transform.gameObject));

                /* After gathering the coordinates and converting them to screen space
              we try to locate which of these have the highest/minimum x and y values.
             The difference between highest/minimum x and y must correspond to
              width and height.*/

                if(_ObjectScreenCord.x > _Xmax.x){

            }



            //Too measure the distance between them, I use the Vector2 method Distance.
            _Height = Vector2.Distance(_Ymax, _Ymin);
            if (_Height > Screen.height || _Height < 0){
                _Height = 0;
            }

            _Width = Vector2.Distance(_Xmax, _Xmin);

            GetComponent<Renderer>().material.mainTexture = movieTexture;

            GUITexture gt = GetComponent<GUITexture>();
            gt.texture = movieTexture;


            transform.localScale = new Vector3 (0f,0f,0f);

}

当我点击我的电视机时，看起来不错：

在我不旋转相机之前看起来不错。相机旋转后，movieTexture在屏幕上有初始位置：

它让我的电视机坏了...... 如何指定movieTexture，它必须具有GetComponent<Renderer>().material.mainTexture的位置？我需要make看起来像这样

但是电视的屏幕必须是必须旋转的电影屏幕，就像电视机的屏幕一样......

你看过投影仪了吗？他们做得非常好，只需改变你想要的纹理。它们通常用于阴影，但任何纹理都可以投射到任何模型上。 http://docs.unity3d.com/Manual/class-Projector.html
