Question by cloudy_day · Oct 24, 2019 at 10:17 AM · javascriptwebglpluginbrowser communication

Unity WebGL calling a function from a jslib file in JavaScript(Vue)

Hey everyone, I have a VueJs Project right now, where I'm building a web page. In order to show 3D Content and let the User work with it. I wanted to embed a Unity Project as WebGL. I´m not a professional programmer, my knowledge is more selfe-taught from what I can find at the Internet.

First of all I created a plugin, as it is explained here. My .jslib file looks like that:

var UnityJavascipt = {

 $JustAWebGLObject:
  {
  },
  SendToJavscript: function ()
  {
              console.log("worked!")
  }     

}; autoAddDeps(UnityJavascipt , '$JustAWebGLObject'); mergeInto(LibraryManager.library, UnityJavascipt );

I can also call "SendToJavaScript" from my C# Script. But now it starts to get unclear for me, since I want to be able to call my "SendToJavaScript" Function (or any other one that will be added later) from a outside JavaScript. In the manual they refer to the emscripten pagefor more detailed information. But for me that all is just very confusing. I already tried to call my function like that in VueJs:

_SendToJavaScript()

But I always get a ReferenceError: _SendToJavaScript is not defined I also read in the forum here, that it would be possible to call the function like that:

UnityInstance.Module.asmLibraryArg._SendToJavaScript()

UnityInstance is the Variable from my index.html file, where UnityLoader get's instantiated. But again I'm getting a Reference Error.

It would be very helpful if someone could explain what I'm doing wrong... Communication between WebGL and Vue are essential for my project but I´m stuck here for days. So thanks in advance!!
