"physi.js" causes the error: "Script cannot be accessed from origin 'null'"

Question

I was trying to play with physi.js library (). I followed all the steps given:

https://github.com/chandlerprall/Physijs/wiki/Basic-Setup

However, I got the error:

Uncaught SecurityError: Failed to construct 'Worker': Script at 'file://172.16.159.200/js/physijs_worker.js' cannot be accessed from origin 'null'.

I tried to go deeper, and saw that the problem with the line:

this._worker = new Worker( Physijs.scripts.worker || 'physijs_worker.js' );

What did cause that issue? The browser is Google Chrome. I checked, the file "physijs_worker.js" appears in the right location.

Answer 1

Browsers don't allow creating workers from local files because that would be a security issue.

Answer 2

Just add the chrome extension https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb?hl=en

and use the extension to launch your index.html. As now it will be running in localhost, there will be no error

Answer 3

Deploy your website on a web server. Without the web server I get the same error.
