events not always processed in correct order

Are the players using a single smartphone between them? If that's the case, I can't understand how you'd be able to get a noticeable discrepancy. The code is running on the phone. Maybe you need to upgrade your phone.

If the webpage was hosted on the phone, yes. But not so sure if it's on a remote internet site. Any network latency would certainly explain discrepancies, especially over slower mobile internet.

I opened http://topffl.co.uk/fiona/buzzer.html in my browser, and then switched off my router. When I press the button, I get a "no internet" error. That suggests there's communication taking place with the remote server.

This is great. You should release it on an app and call it Contractor Cash Generator. I just spent an hour playing this and earned 100's of pounds.

I found it a bit complex at first but great fun when I got the hang of it.

Yeah it redirects - I needed to stop it processing further messages - originally I had it on the same page but would sometimes get the first then second message. But the code is dead simple. I think it is better now that I added the 'clicked' check, but still not perfect.

Thanks all - probably gonna be more hassle than it's worth.

NLUK - happy to take 10%

I tried saving the page to my machine, as a "complete webpage", and running it locally, but the page didn't work.

If you could get it to run on the phone/tablet, with the network disabled, then it might solve the problem.

OK, I got it to work locally on my laptop, as follows:

(NB. this was with Opera; other browsers may be different)

1. Created a folder TEMP on the desktop
2. Opened http://topffl.co.uk/fiona/buzzer.html
3. Saved "complete webpage" in TEMP as buzzer (.html)
4. Pressed Player 1
5. Saved "complete webpage" in TEMP as player1 (.html)
6. Pressed Reset
7. Pressed Player 2
8. Saved "complete webpage" in TEMP as player2 (.html)

Now, if I go to TEMP, and double-click buzzer, it runs with the network disconnected.

Yeah this is the scenario I need to address - with the top countdown players most conundrum solves are pretty much instant. Thanks for checking!

To be exact, the scenario you need to address is that the VAR can't ever see the difference. It's always going to be possible for the "wrong" person to get it - even if you need ultra-high speed video cameras to spot it!

My son adds these comments:

A better solution to using the clean would be to use timestamps + IDs, so you know the time when each person buzzed.

Even better: The click function should know nothing of the state of the buzzer. That should be handled by a separate class. The 'clicked' function informs the game of the click and the game handles what to do with it.

woody1 Thanks for the explanation.

woody1 Thanks for the explanation.

Which was my suggestion in post 2 - record the timestamps and use that to display who won.

[mudskipper]

actually I think it's good enough now - back to one page but the 'clicked' variable seems to do the trick to stop it processing the other click - will do some testing. Thanks all!

you're so smart, well done you

Yes. I know. I was just giving complete information.
