Application.ExternalCall in WebGL

Hi i am having some problems communicating with my browser in webgl by using Application.ExternalCall.my code is this:

Code (CSharp):

1. Application.ExternalCall(func);

.
I have tried 2 different ways to communicate with the browser i have embedded the javascript function in the generated index.html like this

Code (CSharp):

1.     <script type='text/javascript'>
2.      function testScript()
3.     {
4.         alert("test");
5.     }
6.     </script>

i have also tried to link to it by using external javascript. Like this:

Code (CSharp):

1. <script src="Release/scormS.js" type="text/javascript"></script>

Everty time I get the exception error and the webGL program fails to load shown below:

Code (CSharp):

1. ReferenceError: SCOInitialise is not defined version3.js line 1 > eval:1:0
2. "exception thrown: ReferenceError: SCOInitialise is not defined,@file:///C:/Projects/Internal%20Projects/unity5Upgrade/development/test/Unity_Pro%205_Template_v04_webGLTests/Builds/WebGL/version3/Release/version3.js line 1 > eval:1:1

I have seen a few forum posts regarding application.external.call who have similar problems to me. Does this work in webGL, or do I need to do something different, to get it to work?

 

I can't say that I know exactly what's going on in your situation, but I've been using ExternalCall for some things in my WebGL application. I haven't tried embedding the javascript in a tag, but I do have javascript files in my template that are referenced in the index.html file.

I define a method in the javascript file that I call by string name when using ExternalCall (and any parameters that the javascript function accepts).

Is your method SCOInitialise? Perhaps the final 's' is supposed to be a 'z'? Sorry I can't help much more.

 

I made a direct call in unity Application.ExternalCall and it worked. not sure why a direct call to the function worked though

 

We reported this to unity a while back and were told the fix will be in 5.2. Meanwhile you can manually fix it by:

1. Open WebGLSupport/BuildTools/lib/Eval.js in your Unity folder.

2. Replace

eval (str);

with

window.eval (str);
