Hello, after searching information i dont know what i should do to package project with this plugin. I add plugin to project build.cs and set in uplugin file “installed- true” I always have error with UE4-SIOJson.lib no mater what i do package project in unreal 4.17.1, or try compile in VS2017 . Just for example this log from unreal:If anyone know right action to decide this i would glad to learn it. [SPOILER] UATHelper: Packaging (Windows (32-bit)): Running AutomationTool…

Is it related to https://github.com//socketio-…ue4/issues/62 ? try altering your .uplugin to Default to SIOJson.

106

Hi Everybody!
Has anyone tried to use the socket.io UE4 plugin on Unreal Engine 4.18?

Is it compatible at the moment?

107

The git master repo is now UE 4.18 compatible (since 0.6.5). If you don’t mind compiling the plugin yourself you can grab it at https://github.com//socketio-client-ue4. I’m however still looking to fix an outstanding issue or two before releasing a 4.18 binary.

108

I am trying to integrate the plugin in my own editor plugin module using the non-actor-component approach. Added the entry “SocketIOClient” in publicdependencymodule list as well as private and public include paths in PublicIncludePaths and PrivateIncludePaths. No error when I include the “SocketIONative.h” in my PCH and declare a TSharedPtr<FSocketIONative> it compiles but when I create the object through Makesharable then I get the “error LNK2019: unresolved external symbol “public: __cdecl FSocketIONative::FSocketIONative(void)”” error. Using 4.16.

109

Some sanity checks: Does the SIOClientComponent method work?

I’m assuming you’re following the guide https://github.com//socketio-client-ue4#setup which should work, but I haven’t tested making FSocketioNative across module boundaries. You can try adding SOCKETIOCLIENT_API infront of https://github.com//socketio-client-ue4/blob/master/Source/SocketIOClient/Public/SocketIONative.h#L15, let me know if that works.

110

Adding SOCKETIOCLIENT_API did the trick.
Thanks

**Plugin Update to 0.7.0

Changes**

This is a big update. Lot’s of potential crashes should now be fixed with the new architecture, there’s a new plugin scoped connection type, a new callback for connection problems, a few productivity enhancements when using blueprints, and misc utility stuff.

Kindly test it and let me know if new bugs creep up!

Grab it at the usual https://github.com//socketio-client-ue4/releases

Hi! I have a question, is there any way to transform the chat widget to a UMG 2D component? I’d like to “attach” it to a player’s screen/camera lika a common chatbox, and rendering it like a 3D asset it’s quite tricky for my needs x)

Thanks!

113

You probably want to read up on how to add widgets to game UI, see Creating Widgets in Unreal Engine | Unreal Engine 5.3 Documentation. I’m assuming you’re using the example project, https://github.com//socketio-client-ue4-example, in that case you want to attach the *sioclient/Content/ExampleContent/ChatBoxWidget.uasset *to your game UI.

114

Thanks for the answer! I know how to create widgets and put them into the viewport, but I’m having trouble migrating the logic from the ChatWindowActor (to open the input text and send messages etc.) to my character (casting problems in a different places, such as in the function SetupWidgetLinks). What procedure should I follow to achieve it? I’m kinda lost :frowning:

Edit: okay, I think I managed to get it working. I had to make my character inherit from the ChatEmitter interface, and that was almost it. I also have got a reference of my chatboxwidget (just added to the viewport) to link it with the messages.

Thanks!

Hi !
First of all, congrats on your awesome plugin work, you are awesome!
I wanted to ask you something about Linux cross-compiling, as I’m trying to compile a Linux Server with your plugin but it fails in this line:

PrivateClient->connect(StdAddressString, QueryMap, HeadersMap);

With this message:

SocketIONative.cpp:51: undefined reference to sio::client::connect(std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > const&, std::__1::map<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator >, std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator >, std::__1::less<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > >, std::__1::allocator<std::__1::pair<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > const, std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > > > > const&, std::__1::map<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator >, std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator >, std::__1::less<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > >, std::__1::allocator<std::__1::pair<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > const, std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > > > > const&)'`

What is your Linux compiling setup? I’m using the basic config for cross-compile that is shown in the Unreal Engine wiki.

thank you!

Hi !

I’ve encountered a problem when switching to reliable (with acknowledge) messages from server to client.
I’ve saw your implementation of Emit with Callback that allows the server to reply affirmative if it successfully received a message from the client, but now I need to implement the other acknowledgment direction (get a callback from client after a server emit).

To accomplish this, I think that I need to call a server defined function from the client, but the OnEvent (SocketIOClient) event only have two arguments instead of the required three (the actual implementation have Event and Message JSON but in order to accomplish this it should have Event, Message JSON and Server Ack Function)

Is it possible to extend the behaviour of the OnEvent implementation and enable it to reply a server acknoledgement request by function?

On the below link you can find some references:
https://socket.io/docs/server-api/#socketemiteventname-args-ack

And here you find the important code snippet:
io.on(‘connection’, (socket) => { socket.emit(‘an event’, { some: ‘data’ }); socket.emit(‘ferret’, ‘tobi’, (data) => { console.log(data); // data will be ‘woot’ }); // the client code // client.on(‘ferret’, (name, fn) => { // fn(‘woot’); // }); }); Thanks in advance!

118

Meanwhile, I’ve used another emit instead of callback and implemented a proprietary message id dequeue system (for reliability).
Anyway, I think this could be an interesting feature for future releases :slight_smile:

119

Agreed. This would need a little think on how to create a callback reference in blueprint so I’ve added it to issues as an enhancement here: https://github.com//socketio-client-ue4/issues/79

120

Thanks a lot you are so awesome!
Can’t wait to try it :slight_smile:

Hey,

running a bit of a headache here, i’d appreciate any help with this great plugin.
i’m using a button to connect and disconnect ( not using the auto-connect ).

my problem is, if you connect - disconnect - connect, the connection will fail, if you try to connect again while connection is failing, this crash happens :

kindly post issue to https://github.com//socketio-client-ue4/issues with plugin version and steps to reproduce.
Cheers for bug catching!

it deosn’t work with me and i don’t know whats is wrong ! i did everything like the tutorial and it just didnt work , any help ?

124

I want to execute a basic url call with static void CallURL() function. Where do i have to connect the delegate pointer in blueprint which is called by reference?
