Another update just went out for this, with a build of the client now running as a web client (so no download or installation required, just run it directly in the browser). You can run this at: https://locksteparcade.com/Client

Quote from: Simon on January 18, 2026, 01:29:28 AMInteresting idea to reuse the networking engine for multiplayer clone of Gravity Force or of Asteroids. It needs both the precise local steering and the eventual synching of attacks. I guess that missiles become deadly only ~1 second after firing, similar to how builder staircases become solid for opponents only after ~1 second.

So yeah, a similar 'delay frames' thing is going on with those missiles, as you guessed.

The standard delay frames setting of 15 seems to work quite well, generally (maybe just needing to be bumped a bit when playing with a friend who lives in China). And then, at 60fps this works out as a quarter of a second delay between local inputs and visibility of the effects of network inputs.

But those ships can move quite far in a quarter of a second!

So the missiles do a kind of transition between different synch time 'frames of reference', over a short period after firing, when, as you say, they are not deadly (do not yet have collision enabled).

They actually perform exactly the same set of updates, on both sides of the network, so as to guarantee determinism, but these updates are either accelerated or slowed down over the transition period to achieve the synchronisation..

So I posted about this previously, but I now have a game title, website, and so on. I'm actually working on a collection of (lockstep multiplayer) games, but the first game in the collection is a remake of Lemmings.

Anyone who is interested in testing this, please give me a shout!

Lots of great feedback there, thank you! (and plenty for me to get on with)

The releases *are* posted in a (theoretically) public place, since the discord channel I post these on is set to be publicly accessible, but I will consider moving these to a web page, instead.

For managing lag, I use input delay, but with a tricksy setup where each player sees other player's lemmings in old positions. For this to work out, I then implemented a thing where there is also a delay (of the same number of frames) before each player's world changes affect the other players.

You can see this graphically, if you look carefully. As your lemmings build bridges, for example, the newest bridge bits are semitransparent to indicate they only affect you, and, as your lemmings dig, the bits they just dug out are semitransparent to indicate that other player lemmings won't fall through this yet.

More feedback on the weekend.

Nice one. Thanks!

Thomas

Thanks for the report. Great to hear that it runs in wine.

Sorry! I posted a new release on discord but forgot to send this to you, as well.
(Sent, again, by PM)

(I sent you some things by PM, also.)

Quote from: Simon on October 06, 2025, 09:35:09 PMYou haven't shared the background of your project yet, thus: What's your vision? Simply make this kind of game more convenient to play (rather than via networking emulator)? Or do you have new design goals for gameplay/physics/rules/...?

So I played the original lemmings in 2 player mode, way back in the day, and really loved this.
I remember loving the whole chaos of this, and the feeling of there being many possibilities in terms of actions and strategy where streams of lemmings meet, and the feeling that it should be possible to get very good at this.

I woke up in the night recently with the idea of making a 3 player version of this, not having played any of the lemmings clones I see here.

I am now really enjoying working on the project, and feeling really productive. Not sure about final goals, with various possibilities there, but for now I really want to get to the point where it is something that is enjoyable and people want to play.

Quote from: Simon on October 06, 2025, 09:35:09 PMI run Linux. I'm happy to build from source myself. Or I run your binaries (Linux binaries directly, or Windows binaries through Wine).

So I would say try running the Windows binaries through Wine, as it would be great to know if this works, and then I will also look into making a native Linux build. (For this, please let me know what distribution and distribution version you are using.)

Quote from: Simon on October 06, 2025, 09:35:09 PMgeoo and I are experienced Lix players. I'm the author of Lix, and both of us have given extensive feedback for the Clones developers. I'm happy to write some longer posts here for you about the design background of Lix and Clones. Let me know what interests you!

So yeah, there is lots of material I should look at here, but maybe it should be up to me to do my research a bit better, with regards to lessons learned by other lemmings clones. Don't hesitate to point me to stuff, for this!

Quote from: geoo on October 06, 2025, 04:55:30 PMI'm curious to see what you've developed. Back in 2008 we tried to play Amiga Lemmings over network through emulators (and it was laggy and the gameplay wasn't great either, still good fun for the first time trying). Since then I've played a lot of networked multiplayer through Lix (and in the early days also Clones), and I think both engine and level design has come a long way since then!

Simon, the dev of Lix, might also be interested.

I'll probably be free the next two weekends. Only got Linux.

Ok, great stuff!
I've sent you some things by PM.

I'll look into making a Linux build, hopefully before the weekend, but for this please just let me know what distribution (and release version of that distribution) you are using..

I've built a competitive multiplayer version of Lemmings (2-4 players, ~3 minute matches) and need playtesters.
What it is:

Real-time competitive Lemmings gameplay
2 or 4 players per match
Short sessions (3 min per game)
Dedicated server with shared lobby

What I need:

People willing to test over the next couple of weeks
Feedback on gameplay, balance, and bugs
Ideally bring a friend (easier to get matches going)

Time commitment:

~30-45 minutes total
Can be split across multiple sessions
I'll coordinate specific playtesting windows when I'm online

How it works:

I'll send you a credential file for lobby access
Limited to 4 simultaneous games, so starting with a small group
Simple feedback form to fill out afterward

Requirements:

Current release is for Windows, but the game builds on Linux also (so let me know if you are interested in testing there)
Stable internet connection
Discord for coordination
