Question

我尝试将我编码的纹理加载到jpeg，然后作为字节数组从客户端序列化/发送到我的服务器，然后反序列化并将纹理应用于实例化的预制件。除了最后我试图将纹理应用到我的预制件时，一切似乎都在起作用。我收到了错误：

UnityException：纹理＆＃39;鹿＆＃39;不可读，无法从脚本访问纹理内存。您可以在纹理导入设置中使纹理可读。 Player_Data + c__Iterator0.MoveNext（）（在Assets / _Scripts / Player / Player_Data.cs：82） UnityEngine.SetupCoroutine.InvokeMoveNext（IEnumerator枚举器，IntPtr returnValueAddress）（在C：/buildslave/unity/build/Runtime/Export/Coroutines.cs：17） UnityEngine.MonoBehaviour：StartCoroutine（IEnumerator的） Player_Data：PrepareServerData（String）（在Assets / _Scripts / Player / Player_Data.cs：56） PaintCraft.Controllers.c__Iterator2：MoveNext（）（在Assets / _Scripts / ColoringBook / CanvasController.cs：221）

我知道我可以在统一编辑器中使这个可读，但由于我在运行时完成了所有这些操作，我该如何做到这一点？

将纹理转换为jpg

IEnumerator DoGetTexToBytes(Texture2D tex)
    {
        playerObj.texBytes = tex.EncodeToJPG(50);
        yield return new WaitForEndOfFrame();
    }

将所有玩家对象数据组合成字节数组（包括纹理）

public void PrepareServerData(Texture2D texToSend, string typeToSend)
    {
        StartCoroutine(DoGetTexToBytes(texToSend));

        playerObj.texWidth = texToSend.width;
        playerObj.texHeight = texToSend.height;
        playerObj.texFormat = texToSend.format;
        playerObj.tranX = tran.x;
        playerObj.tranY = tran.y;
        playerObj.tranZ = tran.z;
        playerObj.type = typeToSend;
        Player_ID id = GetComponent<Player_ID>();
        playerObj.id = id.MakeUniqueIdentity();
        playerObj.strength = strengthToSend;
        playerObj.hitpoints = hitPointsToSend;

        Network_Serializer serialize = GetComponent<Network_Serializer>();

        // Send Data from Client to Server as many small sequenced packets
        byte[] bytes = serialize.ObjectToByteArray(playerObj);

        StartCoroutine(Network_Transmitter.instance.DoSendBytes(0, bytes));
    }

发送字节，在服务器上接收，然后使用纹理实例化预制件：

[Server]
    public void InstantiatePlayerOnServer(PlayerObject playerObj)
    {
        GameObject go = Instantiate(Player_Controller.instance.serverAvatar, new Vector3(playerObj.tranX, playerObj.tranY, playerObj.tranZ), Quaternion.identity) as GameObject;

        // go.transform.parent = GameObject.FindGameObjectWithTag("Player").transform;

        StartCoroutine(DoLoadRawTextureData(go, playerObj.texBytes, playerObj.texWidth, playerObj.texHeight, playerObj.texFormat));
    }

    [Server]
    IEnumerator DoLoadRawTextureData(GameObject go, byte[] texBytes, int texWidth, int texHeight, TextureFormat texFormat)
    {
        Texture2D tex = new Texture2D(texWidth, texHeight, texFormat, false);
        tex.LoadRawTextureData(texBytes);
        tex.Apply();
        yield return new WaitForEndOfFrame();
        go.GetComponent<Renderer>().material.mainTexture = tex;
    }

您需要在图像的导入设置中设置读/写启用标志。

除非您正在编写编辑器脚本（仅在编辑器中运行，而不是在发布时），否则我认为您无法通过代码执行此操作。
