Car energy readings?

I'm trying to get car energy readings (i.e. the amount of fuel), but I get weird results, namely player.vehicle.energy seems to contain only three possible values depending on the driving direction - when not moving it always contains the value 2666.666, when going forward it's 166.666 and when goin...

Re: Friday Facts #176 - Belts optimization for 0.15

nou_spiro on Reddit pointed this out: Hmm actually 0xFFFF seems invalid accordig to RFC1624 Since there is guaranteed to be at least one non-zero field in the IP header, and the checksum field in the protocol header is the complement of the sum, the checksum field can never contain ~(+0), which is ...

Re: Map download never finishes [14.5] headless windows

If you're generating the checksum based on the entire packet generated just before sending it off, there's no surprise that you'll end up with inconsistencies. If you're generating the checksum from the actual payload data, then packaging and sending it then that should be consistent. If you're sen...

Re: Map download never finishes [14.5] headless windows

My guess is that either your client code or your server code also incorrectly sets the checksum to 0x0000 instead of 0xFFFF. That would be the OS or, at the very least some library they're using - I can't imagine Wube have re-written UDP implementation. And anyway, as it is only outside the NAT tha...

I have marked my code as using MIT license, so yes, you may alter it and post a derived version. Basically you are only required to give credit and include (I believe linking is enough) the original license.

Re: Friday Facts #175 - Programmable Speaker

With the possible simple fix of checking outbound checksums and "fixing" the packet to make this particular one impossible. (Is this possible? I haven't worked with UDP much) This would only work if the problem is in the first NAT (the one in the router of one of the players), as the chec...

Re: Friday Facts #175 - Programmable Speaker

I have posted my guess on the original thread, but I have no real way of further verifying it without the help of someone affected.

TL;DR - possible bug in one or more routers along the way when UDP checksum is 0x0000.

Re: Map download never finishes [14.5] headless windows

Not sure it helps, but I have a guess as to the reason - it may have to do with UDP checksum and tunneling through IPv6. Basically, UDP checksum is optional in IPv4, but not in IPv6, and a wrong or missing (all zeros) UDP checksum will result in a packet being dropped. What I suspect/guess might be ...

Re: [kovarex] [0.14.17] Latency compensation too optimistic on LAN

Is this option only relevant when hosting, or is this client-side?

Also, the config file now has "minimum_latency_in_multiplayer". Can you confirm which is the correct parameter (Or are there two?)

Re: [0.14.13] Multiplayer lag, no latency option

I think I may be facing a similar problem: viewtopic.php?f=49&t=34375

Maybe add an option to limit the minimum latency? Or lower it more gradually, dynamically calculating a "safe" lower bound?

Re: Software Versions: Which comes first 0.3 or 0.12.9?

http://semver.org/

Also, 0.3≠0.30 !!!
0.12.0 is "zero point twelve point zero" (Or replace "zero" with "naught" or "Oh", if you prefer), but definitely not "One point two" or "zero point one point two"

Re: [0.13.4] Overlapping HUD on Some Machines

I don't get an overlap on my 1366x768 laptop monitor, with UI scale set to default... So probably you set the UI scaling too high.

And I seem to remember someone once giving 1024x768 as the minimum resolution, but I'm not sure.

Here's the post : Headless binaries are only 64bit.

If your machine has X libraries, you can use the regular 32bit binares (they ...
