Hi there!
I am working on a game that uses pipes to transmit some data from one process to another, and it all works perfectly when I use blocking operations (e.g. NamedPipeServerStream.Connect) but when I use their asynchronous variants (NamedPipeServerStream.BeginWaitForConnection) the pipe gets disconnected and throws an "operation completed" exception
I have tested my code in my other application which runs on .NET 4.5 and it works fine there.
Code:
NamedPipeServerStream _pipeServer;
NamedPipeClientStream _pipeClient;
void WaitForConnectionCallback(IAsyncResult result)
{
try
{
_pipeServer.EndWaitForConnection(result);
Debug.Log("Connected");
}
catch (Exception ex)
{
Debug.Log("WaitForConnectionCallback Exception: " + ex);
}
}
void StartServer()
{
try
{
Debug.Log("Creating pipe server");
_pipeServer = new NamedPipeServerStream(@"\\.\pipe\localPipe", PipeDirection.Out, 1, PipeTransmissionMode.Byte, PipeOptions.Asynchronous);
Debug.Log("Waiting for connections");
_pipeServer.BeginWaitForConnection(WaitForConnectionCallback, null);
Debug.Log("Creating pipe client");
_pipeClient = new NamedPipeClientStream(".", @"\\.\pipe\localPipe", PipeDirection.In, PipeOptions.Asynchronous);
Debug.Log("Connecting pipe client");
_pipeClient.Connect(100);
Thread.Sleep(1000);
Debug.Log("Cleaning up server");
if (_pipeServer.IsConnected)
_pipeServer.Disconnect();
_pipeServer.Close();
_pipeServer.Dispose();
Debug.Log("Cleaning up client");
_pipeClient.Close();
_pipeClient.Dispose();
}
catch (Exception ex)
{
Debug.Log("StartServer Exception: " + ex);
}
}
Anyone know a fix? Thanks in advance!

Pipe problem for interconnection between unity 5.1 and third app
Hi
I am trying to use named pipes in Unity to pass data to and from another application.
I made test Pipe Server in VS2012
static void Main(string[] args)
{
CreatingPipeServerLoop();
}
const byte sentServerValue = 1;
const byte sentClientValue = 2;
static public void CreatingPipeServerLoop()
{
while (true)
{
Thread.Sleep(500);
using (NamedPipeServerStream pipeServer =
new NamedPipeServerStream("pipetest", PipeDirection.InOut))
{
pipeServer.WaitForConnection();
Console.WriteLine("Client connected.");
try
{
byte answer = (byte)pipeServer.ReadByte();
pipeServer.WriteByte(sentServerValue);
pipeServer.Flush();
}
catch (Exception e)
{
Console.WriteLine("ERROR: {0}", e.Message);
}
}
}
}
And I made Pipe Client in Unity3d 5.1.2f1 :
void Start () {
System.Threading.Thread pipeThread = new System.Threading.Thread(delegate() { CreatingPipeClientLoop(); });
pipeThread.Start();
}
// Update is called once per frame
void Update () {
}
const byte sentServerValue = 1;
const byte sentClientValue = 2;
public void CreatingPipeClientLoop()
{
for (int i = 0; i < 100000; i++)
{
//byte respByte = 0;// MainBaseErrorExcess;
using (NamedPipeClientStream pipeClient =
new NamedPipeClientStream("pipetest"))
{
try
{
pipeClient.Connect();
//Console.WriteLine("Server connected.");
pipeClient.WriteByte(sentClientValue);
pipeClient.Flush();
byte respByte = (byte)pipeClient.ReadByte();
}
catch (System.Exception e)
{
//Console.WriteLine("ERROR: {0}", e.Message);
}
}
}
}
I started Server and then Client in Unity3d 5.1.2f1. Server connected 1-2 times then Unity crashed. Some times pipeClient threw exception "The operation completed successfully".
I launched this test project on 5 PC with Windows 7 (64 bit) every time Unity crashed. It worked only on PC with Windows 7 (32 bit) and Windows 7 on Mac. Also it worked in Unity 4.5, befor I updated Unity I did not know about the problem. How to implement exchange between Unity and another application?

Type or namespace name Pipes does not exist in the namespace System.IO.
I am trying to use the class `System.IO.Pipes.NamedPipeClientStream`but Unity cannot find it.
The build of the project works in Monodevelop but when I go over to Unity it says the following `Assets/PipeClient.cs(5,17): error CS0234: The type or namespace name 'Pipes' does not exist in the namespace 'System.IO'. Are you missing an assembly reference?`
I have changed the API compatbility Level in Unity to .NET 2.0 but to no avail. Do named pipes actually work in Unity?

3D max spline animation to Unity
I have achieved creating a basic animation of a simple coil wire moving from being wrapped around the left side of an iron core to the bottom of an iron core. (see sequence of 3 images):
![alt text][1]
![alt text][2]
[1]: /storage/temp/68035-1.jpg
[2]: /storage/temp/68038-3.jpg
I did this by animating a spline's verticies in 3D Max, and then just choosing to render the spline as a radial round shape to look like a fat wire. I can also achieve the radial wire shape by lofting a circle shape along the spline.
The problem is that Unity does not recognize the spline, so my animation does not translate into Unity. If I make the rendered round spline into an editable poly in 3D max, the shape is imported into Unity, but I lose the animation.
Does anyone know a way to bring an animated spline into Unity from 3D Max? I've tried workarounds like baking the animation, and it does not work.
Thanks!

ReadLine from Named Pipe freezes Unity
Hi everyone.
I've got a problem which is that ReadLine method (StreamReader) freezes Unity when trying to read from a named pipe and that happens just after I start the game or to be more precise when I start to read.
I need to receive as well as send messages using the pipe to another process and ideally I would like to be able to listen to the pipe constantly and send a message at any time.
Here's my code:
using UnityEngine;
using System.Collections;
using System.IO.Pipes;
using System.IO;
public class WEB_HANDLER : MonoBehaviour
{
private string pipeName
{
get
{
return "PIPE";
}
}
private NamedPipeClientStream stream;
private StreamWriter sw;
private StreamReader sr;
void Start()
{
//Starting the pipe
Debug.LogFormat("[IPC] Creating new ClientStream. Pipe name: {0}", pipeName);
stream = new NamedPipeClientStream(".", pipeName, PipeDirection.InOut);
//Connecting to the pipe
Debug.Log("[IPC] Connecting...");
stream.Connect(120);
Debug.Log("[IPC] Connected");
//Initialising Readers/Writers
Debug.Log("[IPC] Starting StreamReader");
sr = new StreamReader(stream);
Debug.Log("[IPC] Starting StreamWriter");
sw = new StreamWriter(stream);
//AutoFlush
Debug.Log("[IPC] AutoFlush = true");
sw.AutoFlush = true;
Debug.Log("[IPC] Starting listening coroutine");
StartCoroutine(Listen());
}
void Update()
{
//Sending messages to the pipe
if (Input.GetKeyDown(KeyCode.Space))
{
Debug.Log("[IPC] Sending message to server");
sw.WriteLine("Test message");
Debug.Log("[IPC] Success");
}
}
IEnumerator Listen()
{
while (true)
{
string message = sr.ReadLine();
if (message.Length > 0) //If message is not empty then print it
{
Debug.Log(message);
}
yield return new WaitForEndOfFrame();
}
}
My guess is that I'm reading an empty string and there is no escape sequence in it so it keeps on reading nothing. If I'm right, how can I solve the problem?

Unhandled exception crashes the game : A heap has been corrupted
Hello,
I make a Windows game that uses **named pipes** to communicate with the outside. I can successfully receive data, but **the game keeps crashing when I send ~5 messages** (yes, 4 is fine but the fifth one makes everything crash, even if messages are identical.. I don't know why).
What happens is a small delay of a second and then the game just closes itself, with no information.
**I tried :**
- Running a "development build" standalone, but the error is not catched into the output log.
- Different ways of sending my message (ASync, normal, by disposing NamedPipeClientStream ...) unsuccessfull.
- Running from the Editor. In this case I can use Visual Studio to debug and I get the error
> "Unhandled exception at ......> (ntdll.dll) in Unity.exe: .....: A> heap has been corrupted (parameters:> ....)."
I have no idea what is happening here. My hypothesis is that unity's System.IO.Pipes is broken.
I would like to find a workaround or if possible to ignore this error. I am already using try-catch when sending messages and it seems like it does nothing. When running from the editor and debugging with VS, I was able to ignore the error and continue the execution. Maybe I can do that to automatically ?
Here is the send method I use now :
public void send(PipeMessage message)
{
try {
pipeClient = new NamedPipeClientStream(".", sendPipeName, PipeDirection.Out, PipeOptions.Asynchronous);
pipeClient.Connect(timeOut);
pipeClient.BeginWrite(message.bytes, 0, message.bytes.Length, aSyncSend, pipeClient);
}
catch (Exception e) {
}
}
private void aSyncSend(IAsyncResult iar)
{
try
{
NamedPipeClientStream sApipeClient = (NamedPipeClientStream)iar.AsyncState;
sApipeClient.EndWrite(iar);
sApipeClient.Flush();
}
catch (Exception e) {

simple namedpipe code not working as expected
Hi, I'm trying to get familiar with named pipes in Unity. To get started I ave a simple test program where the server sends '1' to the client, and the client sends '2' to the server. I got the program running for two console application. Now I want Unity to communicate with my console application. I have the following code.
The console application:
using System;
using System.Text;
using System.IO.Pipes;
namespace PipeSample
{
class Program
{
static void Main(string[] args)
{
using (NamedPipeServerStream namedPipeServer = new NamedPipeServerStream("test_pipe",PipeDirection.InOut))
{
Console.WriteLine("Waiting for connection on named pipe");
namedPipeServer.WaitForConnection();
namedPipeServer.WriteByte(1);
int byteFromClient = namedPipeServer.ReadByte();
Console.WriteLine(byteFromClient);
}
Console.ReadLine();
}
}
}
Unity Code:
using UnityEngine;
using System.Collections;
using System.IO.Pipes;
public class PipeWork : MonoBehaviour
{
void ReceiveByteAndRespond()
{
using (NamedPipeClientStream clientStream = new NamedPipeClientStream("test_pipe"))
{
clientStream.Connect();
Debug.Log(clientStream.ReadByte());
clientStream.WriteByte(2);
}
}
void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
ReceiveByteAndRespond();
}
}
}
So when I run the code and press space, in the Unity console I see '1' as expected.
Unfortunately in the console application I see '1' too after some delay.
Can somebody explain to me why this happens?

Infinite loop with named pipes
Hello everyone,
I'm currently trying to implement a threaded IPC service with named pipes in PipeTransmissionMode.Message. When reading received messages from the server stream, the thread gets stuck in an infinite loop because IsMessageComplete never evaluates to true.
The problem occurs in Unity 5.6.1f1 as well as 2007.1, but not in a .NET 4.5.2 console application using the identical code.
Having spent a whole day on trying to figure this out I'd very much appreciate if someone could point me in the right direction. I'm not sure if I'm doing something wrong or this is a bug in Unity.
Here is a minimal working example:
using UnityEngine;
using System.IO.Pipes;
using System.Threading;
using System.Text;
using System.IO;
public class MinimalPipeExample : MonoBehaviour {
public string pipe = "MinimalPipeExamplePipe";
void Start() {
new Thread(runServer).Start();
Thread.Sleep(1000); // wait until the server is running
using (NamedPipeClientStream cs = new NamedPipeClientStream(".", pipe, PipeDirection.Out)) {
cs.Connect();
byte[] message = Encoding.UTF8.GetBytes("Hello World");
cs.Write(message, 0, message.Length);
cs.Flush();
Debug.Log("C Message sent");
}
}
void runServer() {
using (NamedPipeServerStream ss = new NamedPipeServerStream(pipe, PipeDirection.In, 1, PipeTransmissionMode.Message)) {
ss.WaitForConnection();
MemoryStream ms = new MemoryStream();
byte[] buffer = new byte[32];
do {
int bytesReceived = ss.Read(buffer, 0, buffer.Length);
ms.Write(buffer, 0, bytesReceived);
Debug.Log("S Some bytes read; message complete: " + ss.IsMessageComplete);
// infinite loop here because IsMessageComplete is never true
} while (!ss.IsMessageComplete);
Debug.Log("S Message received: " + Encoding.UTF8.GetString(ms.ToArray()));

UTF8 string acquired through NAMEDPIPES unrecognized by Unityengine
Hi,
the problem is quite simple yet I can't find a solution. I have a string value "sam" that I send through named pipes to my unity application. I receive the string and can print it in the log without issues, but if I use that string to compare with another string of same value created in unity itself (using IF or SWITCH functions), unity finds they don't match.
My code, server side (Winform app):
dataWriter("sam");
void dataWriter(string dataToSend)
{
byte[] _buffer = Encoding.UTF8.GetBytes(dataToSend);
pipeServer.BeginWrite(_buffer, 0, _buffer.Length, new AsyncCallback(asyncWriter), pipeServer);
}
private void asyncWriter(IAsyncResult result)
{
pipeServer = (NamedPipeServerStream)result.AsyncState;
pipeServer.EndWrite(result);
pipeServer.WaitForPipeDrain();
pipeServer.Flush();
}
On the client side (unity app) :
if (pipeStream.IsConnected)
{
Debug.Log("Start Reading");
pipeStream.BeginRead(buffer, 0, buffer.Length, new AsyncCallback(readCallBack), pipeStream);
}
private void readCallBack(IAsyncResult result)
{
pipeStream.EndRead(result);
string stringData = Encoding.UTF8.GetString(buffer, 0, buffer.Length);
Debug.Log("Data received : " + stringData); /// Will successfully print "Data received : sam" in unity logs
if (stringData == "sam") //// Will be FALSE
{
Debug.Log("Data received = sam");
}
else
{
Debug.Log("Data received does not equal SAM "); // Will print this, because it finds stringData is not equal to "sam"
}
}
I tried alot of things: change the encoding format, tried to transform the IF variable from string to byte to string using UTF8 encoding in hopes of having the same string as the data received, tried to trim the BOM from the string if there was any but apparently there is none already, etc.
Please save me from hell on earth!!

How best to make long pipes/cables in unity?
Hi,
I am working on an educational game that allows museum visitors to explore various undersea environments. One of these environments is the undersea portion of an oil rig.
I have or can create models representing the various undersea well heads and components, and these are easy to place into a unity terrain, but I need to connect them to long pipelines that eventually lead up to the surface. I am trying to figure out the best way to do this. These are big heavy pipes, so they don't really need any physics to them. Colliders would be nice, but not absolutely necessary.
From my searches it seems like the best way to do this, may be a line or tube renderer:http://www.unifycommunity.com/wiki/index.php?title=TubeRenderer
Unfortunately, both of these require very large arrays of vector3s which I can't find an easy way to create. I would like to be able to draw a smooth vector spline into 3d space, and render it either as a shaded, or preferably a dimensional tube, and be able to tweak positioning in unity.
The other way, I guess would be to make the pipes all in a 3d program and import them in as meshes. This might be better, but it would be hard to precisely connect them to the other models in unity, and have them lie along the bottom of the unity terrain.
Any suggestions?
Thanks,
-Matt

Using Pipes/Streams Freezes Unity

How do I get named pipes to work in Unity?
Hello,
I've been trying to used named pipes in order to send data from one application to Unity, and I was thinking that named pipes would be a good idea. However, whenever I try creating the Server, I get a win32exception error so that apparently the server is never created. I can create the client, I believe, because I get a NamedPipeClientStream object with no errors, and then when I try using pipe.Connect() I get the same excact win32 error. This is probably because there is no established server to connect to.
My confusion is why I can create the client, but not the server? The syntax for both seems to be the same in its documentation. Here are both the examples I ran, and the reason I am using so many namespaces is because this is part of a larger chunk of code, but maybe the other namespaces are interfering with the pipe declaration.
PipeServerTest.cs:
using UnityEngine;
using System.Collections;
using System;
using System.IO;
using System.IO.Pipes;
using System.Text;
using System.Threading;
using System.ComponentModel;
public class PipeServerTest : MonoBehaviour {
// Use this for initialization
void Start () {
try{
NamedPipeServerStream pipeServer = new NamedPipeServerStream("testpipe"){
print (pipeServer);
}
catch(Win32Exception w){
print(w.Message);
print(w.ErrorCode.ToString());
print(w.NativeErrorCode.ToString());
print(w.StackTrace);
print(w.Source);
Exception e=w.GetBaseException();
print(e.Message);
}
}
}
PipeClientTest.cs:
using UnityEngine;
using System.Collections;
using System;
using System.IO;
using System.IO.Pipes;
using System.Text;
using System.Security.Principal;
using System.Diagnostics;
using System.Threading;
using System.ComponentModel;
public class PipeClientTest : MonoBehaviour {
// Use this for initialization
void Start(){
NamedPipeClientStream pipeClient = new NamedPipeClientStream(".", "testpipe", PipeDirection.InOut);
print (pipeClient);
try{
pipeClient.Connect();
}
catch(Win32Exception w){
print(w.Message);
print(w.ErrorCode.ToString());
print(w.NativeErrorCode.ToString());
print(w.StackTrace);
print(w.Source);
Exception e=w.GetBaseException();
print(e.Message);
}
}
}
I'd also like to note that I'm not sure if this should go in a Start() function. When I use Main() I get no outputs... or maybe that's intended.

changing material color through C# script
Hi,
The question is pretty clear. I thought it was just
`renderer.material.color`
But somehow the color doesn't change. Here is what I've got:
I started with a puzzle, which contains several pieces (or in this case pipes).
The start function of this puzzle is:
// Use this for initialization
void Start()
{
blocks = new GameObject[Size, Size, Size];
for (int x = -Size / 2; x < Size / 2; ++x)
{
for (int y = -Size / 2; y < Size / 2; ++y)
{
for (int z = -Size / 2; z < Size / 2; ++z)
{
GameObject o = (GameObject)Instantiate(Block, new Vector3(x, y, z), Quaternion.identity);
Pipe p = (Pipe)o.GetComponent(typeof(Pipe));
p.PipeModel = PipeTypes[Random.Range(0, PipeTypes.Count)];
p.pipeColor = PipeColors[Random.Range(0, PipeColors.Count)];
o.transform.parent = this.gameObject.transform;
blocks[x + (Size/2), y + (Size/2), z + (Size/2)] = o;
}
}
}
}
The pipe class looks like this:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Pipe : MonoBehaviour {
private PipeState state;
private GameObject instance;
private Color pipeColorHighlighted;
public PipeState State
{
get { return state; }
set
{
state = value;
setStyle();
}
}
private GameObject _pipeModel;
public GameObject PipeModel
{
get { return _pipeModel; }
set {
_pipeModel = value;
instance = (GameObject)Instantiate(_pipeModel);
instance.transform.parent = this.transform.parent;
instance.transform.position = this.transform.position;
}
}
public Color blockColor = new Color(0.2F, 0.3F, 0.4F, 0.0F);
public Color pipeColor;
// Use this for initialization
void Start () {
pipeColorHighlighted = Color.red; // default test color
State = PipeState.Default;
}
// Update is called once per frame
void Update () {
// respond to clicking etc...
}
private void setStyle()
{
if (state == PipeState.Highlighted)
{
print(pipeColorHighlighted);
instance.renderer.material.color = pipeColorHighlighted;
}
else
{
instance.renderer.material.color = pipeColor;
}
//instance.renderer.material.color = (state == PipeState.Highlighted) ? pipeColorHighlighted : pipeColor;
}
}
public enum PipeState
{
Default,
Highlighted,
Hovered,
Selected
}
So far everything looks right. The pipes all get their correct color.
But than, when I want several pipes to be hightlighted, I use this function:
private void setHighlighted()
{
for (int i = 0; i < puzzle.Size; ++i)
for (int j = 0; j < puzzle.Size; ++j)
for (int k = 0; k < puzzle.Size; ++k)
puzzle.getBlock(i, j, index).State = k == index ? PipeState.Highlighted : PipeState.Default;
}
But somehow this doesn't change anything. The colors just stay the same. I gues the problem is somewhere in the instantiation of the pipe objects. But I can't really find it.
Thanks for the help

Creating piping model at runtime
Hello, guys! I'm rather new to Unity and I'm completely new to 3d-modeling, since I have web programming background. So I would be glad to get some advice from more experienced developers.
As a programmer I'm creating an application now (С#+Unity3D) for modeling piping for transporting gas between the cities. The piping must be created and visualized at runtime. The route is calculated at runtime depending on the user's input. I wish to achieve the smooth look of my piping, taking into accout the terrain is not flat (based on real geospatioal data) and the piping length and some other parameters (diameter) are chosen by the user.
I'm not sure my approach is going to work, but that's the only thing I have come up with by now. So, as I think, I have to create a prefab - a piping section - and instantiate it at runtime as many times as I need and then place these copies along the route and position them right.
I haven't succeeded in my approach however. I just feel the lack of tools (or knowledge) that would help me with uniting the sections and positioning them at runtime smoothly. I tried creating a flexible section in Blender and export it into Unity (see https://www.youtube.com/watch?v=IrXAPC-PLLA) but can't export it so that I can bend it by using the key points(anyway, this is another issue).
So my questions are:
- is there any way to achieve the smooth look of the sections connections (so that it looks like a whole, seamless)?
- Is there a conceptually better approach to solve my problem? Maybe I'm not aware of some Unity's features that make the solution easier/faster/better in terms of performance
Thank you a lot for answering! I would be glad to hear any ideas you have on this topic
