I tried this: https://www.scirra.com/tutorials/533/fo ... ing-screen
And it doesn't update the bar width with anything, does this function still work in nw.js? Would it work in Cordova as well?
It doesn't usually show on a PC. Read the documentation. Try running it on your mobile device in a web browser, it will show up.
I'll be using cocoon.io, will it show in that? If not, what other ways of showing a loader bar are there?
Maybe your game loading time is not that long to show the bar. Keep working and try again later with more game content.
It takes, like, 3 seconds to load on mobile and half a second on PC, that should be enough?
Develop games in your browser. Powerful, performant & highly capable.
I think it should be :S . Take a look at this and try: tinyurl.com/zw2x2ve (Works for me at least)
