Issue #5197 mentions adding the ability to pause, seek, move back and forth by individual frames and change
the speed of playback when watching replays. To this, Alayan responded "Pause, rewind and speed change are
all things I would like to have as well. This won't be in 1.5 and maybe not in 2.0, but it's definitely on the roadmap."
I have built the engine side of this and in accordance with the "Communicating with the team" section of the contributing code guidelines I am making a forum post about it.
I have implemented this by means of a ReplayControl class that owns the replay clock. It can pause (setPlaying), move
the head of the playback to a desired time (seek) and change the rate of playback (setRate). The ability to move back and
forth by individual frames naturally falls out of this; you would just seek by a frame-sized delta (or move to an adjacent time
via m_all_times, both can work). This functionality is currently enabled via a --replay-control flag and without it it is inert.
This doesn't change the normal race clock: everything outside of watch replay mode remains untouched.
I have deliberately NOT added the UI. I've built the mechanism, however as it stands there is no user interface that allows
the user to control it. This is on purpose and has been done for two main reasons.
1. Building UI blind without knowing if it is wanted or how the structure should be set out puts my time and effort at risk of being wasted.
2. Where the UI lives, how it looks, where the buttons are, etc. are design decisions that are not my call to make.
This feature has a dependency on the fix outlined in pull request #5837 - without it, seeking backwards would cause the ghost
to freeze in place, which is far from ideal.
(Note to reviewer: the three "removed" lines in world_status.cpp are still there, they're just indented one level deeper and so
GitHub shows them as red. None of the original behaviour has been changed or deleted. You can see that exact same code in
lines 479-481.)
To wrap this up, I'd like to ask a few questions:
Is this something you'd want in the main game?
Should I build the UI or is that something you would be doing?
Is driving the world clock the correct approach?
Where should this live? It currently lives in src/replay: does it belong somewhere else?
Whose job should it be to handle frame-stepping - ReplayControl's or the UI's?
Those are the main questions I'd like answers for however if you have any other questions or concerns I'd be happy to answer them.
Hello everyone,
We are excited to announce the 20th edition of the Unofficial SuperTuxKart Soccer Tournament series, which is the September 2026 Soccer Tournament!
You sign up individually, organizers create teams of three or four players and schedule your matches. We’re still playing three games with a 10 minutes time limit on three different arenas. However, this time Red Team chooses the first arena, Blue Team chooses the second arena, and the third arena is chosen randomly among all available arenas. We also require at least ten add-on arenas this time.

There were talks of getting STK onto Steam, but then that fell through. I personally don't do Steam, but I do do GOG (for reasons that are not particularly relevant, though I could elaborate if asked). The one thing both platforms provide is a way to give money to STK using my local currency, without needing an international credit card, which I don't have. I have bought Shattered Pixel Dungeon and Cave Story on GOG, games that I have enjoyed for free, just to support them.
There's also uh... a thing called Xsolla. It's one of the options for buying Kandria, which is a game recommended by Hempuli, who is a famous guy, who made Baba Is You, so it might be trustworthy. I dunno. They do seem to accept multiple currencies, but I have never bought anything through them. Guess I could do the test if there's any real interest. For science. I do find a lot of complaints about them online, though, and they're into "AI".
The first test version of my new jungle track is now available. Of course, there are still a few things that need to be improved, but I’m taking a break from this track and will start working on the next one. If there are things that bother you as well, feel free to let me know anytime. Someday—though it’ll probably happen next year—I’ll be done with it. I’ve been working on this track for over two months. In a few days, if I can manage it, my first SuperTuxKart video will also be up on YouTube.
To play the track, all you have to do is go to the official STK Add-on Store. Of course, the track still needs to be approved first.
Few days ago, I learned that you can make several animation for assets, and game will choose randomly what to play in current race, you need just put markers on timeline "start" and "end" several times to separate animations, like this.
So ... that gives me an idea, what if add this method to the karts as well?
When you repeat same markers of animation, for example "winning animation", and when you will win the race - game will randomly choose one of winning animations, that can be also for "loosing" animation, for "hit", for "jump", etc ...

Well, the Vulkan pipeline is unfinished yet, so I decided to finish this, but I need help, as I'm learning Vulkan yet and studying the graphics engine of the game.
Someone with experience with Vulkan coding can help me (and DON'T DARE TO USE LLM IN THIS, DAMN).
Things to finish:
- Post processing (stk-code/src/graphics/post_processing.xpp)
- Shadows
- Maybe new shaders?
- More things to see in video settings.
Maybe, I will create a repository to make easier the co-working.
Can you explain me one thing - Why are all assets - houses, people, animals, plants, etc. so big on tracks? They are not fit to the sizes of the characters on the karts. When I drive along the tracks i always think - Why everything is so big here? All tracks are so beautifully made, but there is no feeling of awareness that these tracks are created for the characters. Right now it feels as if they are just some strangers who accidentally drove into a places that not belongs to them.
And because everything is so big, I can't enjoy the beauty of the tracks on the fullest because everything is too high, so i have to drive back to get better look at some objects.
I just thought maybe you would consider this question and maybe adjust the sizes?
In any case, i just sharing with you my thoughts I love this game, it's very enjoyable to play
