Blockcopy incoming websocket data to shared byte array in a WebGL JS Plugin

Hi all!

I have managed to implement a shared byte array between a javascript plugin and C# in a Unity WebGL build.

We also implement a websocket for communication with a server which is firing binary data (20 byte blobs) of a known format at us. I have implemented the onMessage callback to receive the binary data as follows:

Code (JavaScript):

1.  
2. window.wsclient.onmessage = function(evt) {
3.             if (evt.data instanceof ArrayBuffer) {
4.                 for (var i = 0; i < SharedByteArray.length; i++) {
5.                     SharedByteArray[i] = evt.data[i];
6.                 }
7.             }
8.             SendMessage('SceneManager', 'RecvString', "1");
9. };
10.  

I believe this method will work for transferring the incoming data into the shared byte array, however I am wondering if there is a more efficient "BlockCopy" equivalent rather than having to copy each byte at a time? We are expected potentially quite a lot of data.

Any help is appreciated,

Cheers!

Hi @palex-nx

Thanks for the reference. This is good, except how would I copy that into the already initialized shared array? I initialize it in the plugin at runtime based on a byte array passed in from Unity so I cannot simply reassign it to 'buffer.slice(0)'. Is there a way in JS to do something like this:

Code (JavaScript):

1. MySharedByteArray[0] = incomingBuffer.slice(0);

I want to copy it straight into that memory.

Thanks for your help!
