通过代码将纹理标记为读/写[重复]

Question

我正在尝试在 iOS 手机上下载、设置和保存纹理，但我一直遇到同样的错误：

(纹理需要被标记为读/写才能在播放器中获取RawTextureData UnityEngine.Texture2D:GetRawTextureData())

它仅在 iPhone 转换后发生，但在 macOS 上运行良好。感谢您的帮助:)

       UnityWebRequest www = UnityWebRequest.GetTexture(url);
       AsyncOperation op = www.Send();

       while (op.isDone == false)
       {
           yield return new WaitForEndOfFrame();
       }
      if (www.isError)
        {
            Debug.Log(www.error);
        }
     else
        {
            texture = ((DownloadHandlerTexture)www.downloadHandler).texture;

            Texture2D texture2d = new Texture2D(texture.width, texture.height, TextureFormat.ARGB32, false);
            texture2d.LoadRawTextureData(texture.GetRawTextureData());
            texture2d.Apply();

            byte[] bytes = texture2d.EncodeToJPG();
            Debug.Log("after");

            File.WriteAllBytes(Application.persistentDataPath + "/" + name + ".png", bytes);

            texture = texture2d;

            setTheTexture();
        }

您需要选择要在函数中使用的所有纹理，并在编辑器中将它们的读/写设置为启用。
