Got any context/ blueprints that cause that?

168

When im testing the game i have two users connected. Then they start to connect and disconnect every time by no reason.
Then i close PIE, and when i try to play again and the connection hangs and the editor crashes

Thanks for the context, seems related to: https://github.com//socketio-client-ue4/issues/126 Iā€™m still chasing down the root cause of it.

Try an earlier release e.g.: https://github.com//socketio-client-ue4/releases/tag/0.10.0 which doesnā€™t have the issue and let me know if it works. Iā€™ve added a 4.22 version, but keep in mind that v0.10 only works on windows/linux

170

Im working with mobile in mind, so i am going to wait for the fix . By the way have you considered using socket as singleton instead//additionally to component?

171

If you want to use something not inheriting a uobject or wish to control itā€™s life cycle, consider using the c++ base class FSocketIONative https://github.com//socketio-client-ue4#c-fsocketionative, Itā€™s still uses ue4 native types so the mental leap shouldnā€™t be that hard. The USocketIOClientComponent uses this class under the hood and you can look into that class for example implementation.

That said Iā€™ve seen some pings for people wanting to spawn a UObject type in blueprints, maybe expose a singleton to create a component without attachment? Iā€™d be wary to complicate the UX too much though. Iā€™d generally recommend dropping an actor into the world with the component and forwarding your reference to the component elsewhere. Or if youā€™re loading levels, use level streaming with a top level that is permanently loaded.

172

Thanks for your plugin.
I connect to my own server using ip address like:http://0.0.0.0:0
And it worked in windows.
In the case of IOS platform,though I check the ā€œAllow web connection to non-https websitesā€,it doesnt work.Could you please give me some advise to solve the problem.Thanks.

173

thank you im going to try it

174

Due to popular demand Iā€™ve now added a way to statically construct a component correctly which should work largely anywhere, documentation for the new feature can be found here: https://github.com//socketio-ā€¦ient-component

The early release for this is available here: https://github.com//socketio-client-ue4/releases/tag/v1.1.0e(1.0.11)

It will also land in a stable release with other bugfixes later as 1.1.0.

175

This is amazing.Handle it from the Gameinstance was exactly what i was looking for! great job

Dear Folks,
unknowing if there is any information about it already (I found none), I post here in desperation for help :smiley:

Right now I have a setup working with the plugin between two unreal projects to transmit data (pictures as binary, text and number information as jsonā€¦). But it wont emit data that seems bigger than only a bit of text. And also it does not work if I repeatedly emit smaller things.

This is my setup to transmit images I collect. The image itself works great with the same setup without a loop.
But when I try this, I can see in the server console that it sends 2 or 3 times and then disconnects the client.

After that I have a ghost client that connects and disconnects. With other data I had the problem, that the ghost client kept reconnecting, even if I closed Unreal (it somehow kept a process running in the background with 20% CPU usage, and multiplied itselfā€¦)

At this Point I just have no idea where to start since I have no Idea what and where the Error comes from. Do I need to make another setting in the plugin? I use the node server that came with the chat server example, is that wrong?

I really appreciate any help or wink in the right direction!!

best
Luk

About the ghost client. do you have the connect options as automatic?
you use gamemode Begin and End? also looks like scooped connections has some issues.

I suspect it has to do with the standalone asio having some bug in the earlier v1.11 that is used in plugin v1.0. An early test inside https://github.com//socketio-client-ue4/tree/issue-126 which upgraded asio (to v1.13) seems to work with large data again (Iā€™ve been testing it with raw audio binaries interwoven). If you want to try the unstable build, pull from issue-126 branch and compile. Iā€™ll be merging the potential fix into a stable build when I finally address issue-126 (reconnection cycle problem).

179

I made a change. When i stop the PIE while is emiting on update the editor crashes

added this line
if (!NativeClient.IsValid())return;

Hello!

I canā€™t connect to server. Event ConnectionProblem is happened, but event Connect (or Disconnect) isnā€™t. Actor with SocketIOClient Component place at level, server is ok too, I suppose. How can I to find out reason of this problem? What can I do?

Thanks for help.

181

Nice! Likely only possible with statically allocated components, but this is a good catch. Open a pull request on https://github.com//socketio-client-ue4 with the change and Iā€™ll merge it in :slight_smile:

182

Uhm i donā€™t know how to do that :confused:

183

If youā€™re willing to try something new, check out Creating a pull request - GitHub Docs to learn how to make a pull request.

The basics:

  • Fork the repository so you get a local copy.
  • Make the code change and commit to your local fork
  • Open a pull request with the change to the main repository and Iā€™ll merge it in :slight_smile:
184

Open an issue on https://github.com//socketio-client-ue4/issues with detailed description on how to reproduce your bug and Iā€™ll take a look

I think i didi it
