我需要将一个RenderTexture对象保存为.png文件,然后将该文件用作包裹3D对象的纹理.我的问题是现在我无法使用EncodeToPNG()保存RenderTexture对象,因为RenderTexture不包含该方法.如何将RenderTexture对象转换为Texture2D对象？谢谢!

// Saves texture as PNG file.
using UnityEngine;
using System.Collections;
using System.IO;

public class SaveTexture : MonoBehaviour {

    public RenderTexture tex;

    // Save Texture as PNG
    void SaveTexturePNG()
    {
        // Encode texture into PNG
        byte[] bytes = tex.EncodeToPNG();
        Object.Destroy(tex);

        // For testing purposes, also write to a file in the project folder
        File.WriteAllBytes(Application.dataPath + "/../SavedScreen.png", bytes);
    }
}

如何在网格布局中获取对象的实际位置？在我当前的迭代中,symbolPosition保持返回0,0,0.

public void OnPointerClick (PointerEventData eventData)
{
    // Instantiate an object on click and parent to grid
    symbolCharacter = Instantiate(Resources.Load ("Prefabs/Symbols/SymbolImage1")) as GameObject;
    symbolCharacter.transform.SetParent(GameObject.FindGameObjectWithTag("MessagePanel").transform);

    // Set scale of all objects added
    symbolCharacter.transform.localScale = symbolScale;

    // Find position of objects in grid
    symbolPosition = symbolCharacter.transform.position;
    Debug.Log(symbolPosition);
}

当多个玩家连接到我的服务器时，我无法通过我的网络发送数据。我收到错误：

Trying to send command for object without authority.
UnityEngine.Networking.NetworkBehaviour:SendCommandInternal(NetworkWriter, Int32, String)
Network_Transmitter:CallCmdPrepareToReceiveBytes(Int32, Int32)
<DoSendBytes>c__Iterator0:MoveNext() (at Assets/Scripts/Networking/Network_Transmitter.cs:63)

Player_Data:OnStartLocalPlayer() (at Assets/Scripts/Player/Player_Data.cs:44)
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

错误发生在我的 Player_Controller 脚本CmdPrepareToReceiveBytes(transmissionId, data.Length);中的函数行中DoSendBytes。我将这个脚本与我的 Network_Transmitter 脚本一起附加到一个游戏对象，其中 NetworkIdentity 被分配为本地玩家权限。一旦在服务器上完全接收到这个字节数组，我就会根据发送的数据在服务器上实例化一个预制件（serverAvatar），如下所示：

public class Server_InstantiatePrefab : NetworkBehaviour
{
    [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;

        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 …

我在网页上设置了一个画布，其中运行着js动画，该动画填充了整个浏览器窗口，但是当我调整窗口的大小时，似乎无法自动调整画布的大小以适应新的窗口大小。有人可以告诉我我需要添加到我的js中才能正确获得此功能吗？谢谢！

var canvas = document.getElementById('canvas');
var makecodeplay = canvas.getContext('2d');
canvas.width=window.innerWidth;
canvas.height=window.innerHeight;

makecodeplay.clearRect(0, 0, canvas.width, canvas.height);
makecodeplay.fillStyle = "rgb(75,77,81)";
makecodeplay.fillRect(0, 0, canvas.width, canvas.height);

function randomPaint(inX, inY) {
   
    var x = Math.floor(Math.random() * canvas.width);
    var y = Math.floor(Math.random() * canvas.height);
    var r, g, b;
    r = Math.floor(Math.random() * 255);
    g = Math.floor(Math.random() * 255);
    b = Math.floor(Math.random() * 255);
    makecodeplay.beginPath();
    makecodeplay.fillStyle = "rgba(35,37,41,0.3)";
    makecodeplay.fillRect(0, 0, canvas.width, canvas.height);
    makecodeplay.fill();
    makecodeplay.closePath();

    makecodeplay.beginPath();
    makecodeplay.strokeStyle = "rgba(" + r + "," + g + "," + …

我正在尝试使用 unity 创建一个小测试应用程序。我正在构建应用程序的一个实例并将其设置为主机，然后在统一编辑器中作为客户端运行另一个实例。在当前的迭代中，我有一个按钮，应该在按下时截取屏幕截图，然后将该屏幕截图发送给所有客户端。但似乎没有任何效果。我遇到的最初问题是 ReadPixels 错误：

ReadPixels was called to read pixels from system frame buffer, while not inside drawing frame. UnityEngine.Texture2D:ReadPixels(Rect, Int32, Int32) UNETChat:OnPostRender() (at Assets/Scripts/UNETChat.cs:50) <TakeSnapshot>c__Iterator0:MoveNext() (at Assets/Scripts/UNETChat.cs:42) UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr).

Beyond that, once solved I'm sure that there is a lot of additional work in here that's off the mark. But I'm just starting here. Thanks for the help!

我在python脚本中遇到了这种语法,并看到它被称为切片赋值.你如何在C#中编写这种语法？

self.nav[:] = []

用于构建文件列表的等效代码是什么？我正在创建这样的数组.

arctopithecusImages = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg");

我试着用它来构建我的List,但是它没有用.这样做的正确方法是什么？

List<FilePath> arctopithecusImageList = new List<FilePath>();
arctopithecusImageList.Add(Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg"));

从switch语句返回GameObject的正确方法是什么？当我尝试返回头像时,我得到错误'使用未分配的局部变量'头像''.关于如何使用switch语句返回工作,我有点混淆了.谢谢您的帮助!

private GameObject GetAnimalAvatar(string animal)
{
    GameObject avatar;

    switch (animal)
    {
        case "bear":
            avatar = ForestGameManager.fgm.bearAvatar;
            break;

        case "boar":
            avatar = ForestGameManager.fgm.boarAvatar;
            break;

        case "doe":
            avatar = ForestGameManager.fgm.doeAvatar;
            break;

        default:
            break;
    }

    return avatar;
}
