Season's chat - R4K / Re: 2026 - Guest Tracks - R4K

Last post by Spoonboy - Today at 11:09:38 PM

Hi, @Victor Narl reached out to see if I could supply a track for October. At first I thought I'd struggle, as things are busy for me here. But I've decided to try, and have made a start. I'm working on a couple of layouts as long-term projects, but these may be more suitable for CCC one day, as I like to compare different cars on the same track.

So this will be a clean sheet. It may not end up as a classic, but I'll try to make it entertaining

Stunts Reverse Engineering / Re: Working native port of Stu...

Collision: It works simply by walking every remote car in the update function. Iterate over the cars in the race, put it in the "opponent slot" (the original game also has something like this, for its AI opponent). We effectively end up reusing the old code simply by iterating over the opponent cars we have, there is already collision checking code, and code for the actual collision (the broken glass, explosion that we all love), we just ensure that we check multiple cars this way.

The important thing to understand is that there's no shared collision resolver at all, and the design still supports e.g. multiple collisions happening simultaneously because every client is fully authoritative over its own car. So yes, a simple way to cheat with this system is to just run a malicious client that ignores crashes.

But it is a starting point.

Another recent finding about sound and music modification on GPC:

Can this somehow be related to any previous post messages?

The author has promised a post about that mod, I guess it will appear on their blog. Maybe they will also say whether they were inspired by the recent developments.

After further testing, I discovered something interesting: the start/finish line behaves normally only if at least some portion of the track has been driven in the correct direction (merely driving forward from the starting line until reaching the next tile is sufficient to prevent any weird behaviour). If you initially leave the start/finish tile in the wrong direction, and subsequently never drive any part of the track in the correct direction, the start/finish line either will not work at all, or will instantly end the race when the start/finish tile is entered without actually crossing the line.

Judging from your screenshots, it looks like you triggered the latter behaviour, as the Audi appears to be on the boundary of the start/finish tile rather than the start/finish line itself.

Yes, that sounds consistent with what I can see in both the original DOS game and the port.

Thanks for confirming.

Hello my friends,

It's true that I 'm not that interested.

Have a nice day!

Yours, Alain il Professore.

Hey @Victor Narl! How are you going to get experience, if you give up on creating a track? Please reconsider, we'd like to see your track on the list!

Also, Alain appears to have delegated the whole thing to ChatGPT, which makes me feel like he's not that interested. If you really want to give up your slot, we can also ask around.

The idea of motivating riders to join teams is good, but counting all riders would favor larger teams. Since teams can currently have 2–4 riders, I think keeping the top two scores would make the competition more balanced.

Hello my friends,

Thank you very much for the trust! 🙂

I gladly accept the invitation to design ZCT305, the December 2026 ZakStunts track.

You are absolutely right: last December I would have liked to take part in the track selection, but I simply missed the opportunity. So I'm especially happy to get the chance this time.

I'll do my best to create a track that fits the ZakStunts spirit: interesting to discover, fun to race, and hopefully with enough depth to keep pipsqueaks searching for those last ticks until the end of the month. And let's not forget honoring the song name tradition.

So, officially: I accept ZCT305! 😎🏁

Thanks again!

Given all experience creating interesting tracks within the ZakStunts concept, I would like to delegate my rights to create the track ZCT305 to @Alain il professore. I'm sure he wanted to participate in the track's creation, but simply didn't have time to take a place on this forum in time due to his lack of time last December. I ask @Alain il professore to confirm here his consent to accept the December track ZCT305.
