I am trying to follow the Colyseus real-time multiplayer tutorial to try to create a simple multiplayer FPS game. I can’t even connect to the server. It looks like the client can’t get the Colyseus JS file from the external source I added.
This is not an error, but a warning. It says it cannot find source maps for the colyseus js file (which indicate that the actual js is loaded, but simply can’t find maps, which you most probably don’t need). Source maps are only useful for viewing source code of the JS file in the developer tools.
