Show HN: A mecha game where you and your friends pilot the SAME giant robot

https://www.mecharoyale.com

2 months and 3,000 prompts later, we have Mecha Royale (mecharoyale.com)It’s a browser-based battle royale with 100 mechas fighting across one massive map. But the part I’ve been having the most fun with is squad mode where you and your friends climb into the same mecha.One person can pilot it while your teammates control different weapons. So you’re basically yelling at your friends while...

so the entire map including biome are deterministically, procedurally generated from seed, and yes, they're progressively generated as the player travels to reduce the loading speed.

I built a procedurally generated pirate MMORPG using Fable.

The entire game is pretty much built using Claude Code. The procedural world generation, gameplay systems, multiplayer features, and much of the supporting game logic. One thing I found especially interesting was how compact the final output became.

The entire game is only 5MB, with no image, 3D model, or sound assets. Everything is generated through code.

The game supports up to 250 players and includes a large world with different landscapes, vegetation, thousands of items, cosmetics, animals, monsters, and ships.

Players can chat, trade, form parties, play poker and blackjack, visit shops and taverns, hunt, forage, fight monsters, participate in world events, sail, upgrade ships, install cannons, and recruit crewmates.

It is free to try in the browser at play.arrr.fun

ARRR.fun is a procedurally generated MMORPG built primarily with Fable. Not a single image, 3D model, or sound asset was used.

It features a massive world with diverse landscapes and vegetation, thousands of unique items, cosmetics, animals, monsters, and ships, with full multiplayer support for up to 250 players.

Players can chat, trade, play poker and blackjack, visit shops and taverns, hunt, forage, fight monsters, and participate in world events. They can also sail across the world, upgrade their ships, install cannons, and recruit crewmates.

We launched six days ago, and thousands of players have already played.

Thanks for checking it out!

Hello all, I made a crypto trading bot using ChatGPT + Python and I wanted to share it with you. I don’t know quant or Python, but it took me 1 day to build it thanks to ChatGPT.

It's a fun little side project and it's definitely not stable nor reliable.

Thanks!
Re:I'm open-sourcing my game engine on Thursday December 21, 2023 @11:24PM (#38730916)
Thanks for the question. We consciously decided to make our engine more opinionated compared to other modular alternatives, because we want to be extremely fast at developing 2D multiplayer games. For example, I made a simple MMORPG in 2 hours (https://www.youtube.com/watch?v=GZVsxkALR5U).

I believe that there's an inverse correlation between ease-of-use and level-of-customization. We chose the former to address the gap between casual game devs and multiplayer games which are known to be difficult to build.

I wouldn't recommend you modify the JSON directly, as it's quite illegible and bloated. There are actions in modd.io that allow you to modify the map directly. One creator in our community is dynamically generating the map using ChatGPT. He's building a hide & seek sends a prompt to generate 2D map JSON then loads it in the map every time the new game round begins. I'd share the game, but he hasn't published it yet.

Also, there is a community member who's building an interpreter for our game JSON such as https://pypi.org/project/pymodd/

We have an active community who are creating between 150 to 300 new games every day. Having a low-barrier of entry for both game devs & players def helps. (No download/signup required)
Re:I'm open-sourcing my game engine on Thursday December 21, 2023 @10:39PM (#38730696)
Oh, I've already done this! Happy to help. Feel free to DM me here on Discord. (I should probably make a YouTube tutorial for this)
Re:I'm open-sourcing my game engine on Thursday December 21, 2023 @09:09PM (#38730085)
sounds exciting! let us know if you have any questions. we have a Discord link on our homepage as well.
Re:I'm open-sourcing my game engine on Thursday December 21, 2023 @08:58PM (#38729998)
This is pretty much spot on. Having a low barrier of entry (no download/signup/paywall) + being easy to use certainly helps.

Thank you for checking it out!

Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev.

We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games.

I hope some of you guys will find this useful. Would love to hear feedback also. Thank you.

Thanks!

The games are hosted on our bare-metal servers, but you do have the option to self-host games as well. Our engine is open source (https://github.com/moddio/moddio2)
Re:Moddio: The multiplayer first game engine on Friday November 10, 2023 @12:16PM (#38221501)
It should be very easy. For example, here's a video of myself making a random number generator: https://youtu.be/8az4jRItXok?t=9147
Re:Moddio: The multiplayer first game engine on Friday November 10, 2023 @12:09PM (#38221414)
Good question. We are active. Currently, the site gets about 10k DAU and there are lots of creator discussions happening on Discord + Forum.

Co-founder here. Additionally, you are able to set different stream mode for each entities and script actions which allows you to customize your players’ multiplayer experience. For example, doing a lag compensation by syncing player unit positions (between server and client) but not rotation nor bullet positions
Re:Unity to lay off 8% of its workforce on Thursday May 04, 2023 @06:36AM (#35813414)
I think Roblox’s business model is similar to that of sweatshops’ in a sense that they’re enabling minors to earn money when there are no better alternatives. Is that truly a bad thing? From westerner’s perspective, a sweatshop might be an exploitation but for the workers’ perspective it’s the best opportunity available to them.
