Unity WebGL call a .exe file on a server and get back data

Question

I'm currently working on a project that will be buildt in webgl. It uses an asset that runs an .exe (cmd window) file to convert data that I need. But this does not work in webgl as it can't call the .exe file.

So now I'm searching for solutions. I tried to change paths and everything but nothing worked. Now my thought would be to make a second unity project that runs on a server and waits for a request. When the request gets sent out of the unity webgl project, the unity project on the server hears that request and runs the asset, after it finishes, it will send back the gameobject created. But I haven't tested it yet.

Would there be any other possible way?

Answer 1

Why do you want to download an *.exe file to get assets from a server?

Your issue sounds like you want to implement a normal gameclient with an unity gameserver that provides you with assets.

The good news is Unity implemented this one for you! :)

You can create an assetBundle and get it via network communication: https://docs.unity3d.com/ScriptReference/AssetBundle.html

Steps would be:

1. set up a public reachable webserver ( for local testing you could use XAMPP )
2. place your package there (htdocs)
3. follow the instructions from link above.
