镜子不反射光

Question

I1m当前正在使用此（Unity - Can I make a mirror in 2D?）代码制作反射面。问题在于它是镜像对象，而不是灯光。

有什么解决方案或工作方法吗？

代码：

public class CameraToSpriteMirror: MonoBehaviour
{
public SpriteRenderer spriteToUpdate;
public Camera mirrorCam;

void Start()
{
    StartCoroutine(waitForCam());
}

WaitForEndOfFrame endOfFrame = new WaitForEndOfFrame();

IEnumerator waitForCam()
{
    //Will run forever in this while loop
    while (true)
    {
        //Wait for end of frame
        yield return endOfFrame;

        //Get camera render texture
        RenderTexture rendText = RenderTexture.active;
        RenderTexture.active = mirrorCam.targetTexture;

        //Render that camera
        mirrorCam.Render();

        //Convert to Texture2D
        Texture2D text = renderTextureToTexture2D(mirrorCam.targetTexture);

        RenderTexture.active = rendText;

        //Convert to Sprite
        Sprite sprite = texture2DToSprite(text);

        //Apply to SpriteRenderer
        spriteToUpdate.sprite = sprite;

    }
}

Texture2D renderTextureToTexture2D(RenderTexture rTex)
{
    Texture2D tex = new Texture2D(rTex.width, rTex.height, TextureFormat.RGB24, false);
    tex.ReadPixels(new Rect(0, 0, rTex.width, rTex.height), 0, 0);
    tex.Apply();
    return tex;
}

Sprite texture2DToSprite(Texture2D text2D)
{
    Sprite sprite = Sprite.Create(text2D, new Rect(0, 0, text2D.width, text2D.height), Vector2.zero);
    return sprite;
}
}
