我如何使編程的紋理可讀

我試圖加載一個紋理，我編碼到一個jpeg，然後序列化/發送爲一個字節數組從客戶端到我的服務器，然後反序列化和應用紋理一個實例化的預製件。除了最後我試圖將紋理應用於我的預製件時，一切似乎都在起作用。我發現了錯誤：我如何使編程的紋理可讀

UnityException: Texture 'deer' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings. Player_Data+c__Iterator0.MoveNext() (at Assets/_Scripts/Player/Player_Data.cs:82) UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17) UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator) Player_Data:PrepareServerData(String) (at Assets/_Scripts/Player/Player_Data.cs:56) PaintCraft.Controllers.c__Iterator2:MoveNext() (at Assets/_Scripts/ColoringBook/CanvasController.cs:221)

我知道我可以在統一編輯本可讀的，但因爲我做這一切在運行時，我該如何做到這一點？

轉換紋理JPG

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

組裝所有選手對象數據爲字節陣列（包括紋理）

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)); 
    }

發送字節，接收關於服務器，然後實例化一個預製與質地：

[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; 
    }

您需要設置讀/寫啓用標誌的圖像'的導入設置。

我不認爲你可以在代碼中做到這一點，除非你正在編寫一個編輯腳本（這隻能在編輯器中，還不時出版）。

那麼我如何加載使用紋理編碼爲jpeg作爲編程上的預製紋理？我必須將我的紋理編碼爲jpg，以便我可以通過網絡快速發送它。 – greyBow

他從代碼中詢問，而不是編輯。 @greyBow查看重複 – Programmer

@programmer我查看了另一個線程，除非我遺漏了一些東西，它仍然沒有解釋如何獲取這個重複的紋理並將其編碼爲jpg以減小文件大小。我嘗試編碼在另一個線程創建腳本的新紋理，但我仍然有相同的錯誤是有任何其他方式編碼紋理JPEG，然後以編程方式讀回來？ – greyBow
