Button presses in demo

[Dokujisan]

So from what is IN the demo, you can't infer which keys were actually pressed. And adding that to demos would not be possible without making a new demo format.

Would it need to be completely different? Or just have additional packets added to the stream for the button information? If a dem player did not recognize the extra packets (like an older version of Nexuiz), it would just ignore them.

It seems like it would be an option during the record process, so if someone were making a demo and did not want the buttons to be displayed, they would have that option. So ai's point would not be an issue.

IMO the whole idea is kinda of stupid.

I'm not sure why you think that. On another thread, you were suggesting the idea of a demo tutorial for learning Nexuiz tricks. This would go perfectly with that idea, wouldn't it?

No, Quake family protocols do not work like that. If any unsupported command is part of a packet, this is a fatal error and causes a disconnect (or in case of a demo, stop of playback). It can't be done in a better way without adding a length word to each command, which would cause quite some more traffic (about 10% to 30% more).

Is this even possible in theory??? Not all have the same bindings. Some might not even use mouse. And what if I have bound several keys to +forward etc???
But I must confess I have thought about this idea before (months ago)... but never shared it to anyone

Actually, I never thought about recording the actual KEYS, but just the functions (like "strafe left", "secondary fire", "jump").

Yeah, that seems more sane to me. And display arrows on screen for the movement. I think I saw this in Quake3 or CPMA.

I would conclude that this is not worth the time. Sorry.

Well such a thing was useful in quake3 / cpma as it had quite complicated movement and that feature could show beginners what buttons to press and WHEN. With the current more simple movement in Nexuiz i fail to see this as a useful feature.
If you just want it to CREATE a demo you could use aliases:
alias +myforward "echo pressed FORWARD; +forward"
alias -myforward "echo released FORWARD; -forward"
and similar ones.
