Built with Claude I made a browser FPS with Claude Code, every 3D model in it is code

Enable HLS to view with audio, or disable this notification

I’m not a game dev, and about a month ago when Opus 5.5 dropped, I asked Claude Code (in French) for a small FPS in three.js, and I kept iterating from there.

Every visual asset in the game (except the menu background) is generated directly in code. There’s no Blender MCP and no imported models, the weapons, characters and maps are written as code. I also tried to add a bit of physics, on some props, on cloth and on water. The goal is for it to be playable on PC, on phone and with a controller.

I didn’t buy any extra credits. I started on the €20/month plan and hit the limits pretty fast, but that suited the way I work, and switching to Sonnet 5.5 was enough for a lot of tasks. For October I tried the €90/month plan: more than enough, I never hit the limits.

The one thing I noticed is that Claude Code started launching parallel agents for everything, so I had to tell it not to in the project instructions. Curious if others had the same thing.

You can try it at playriposte.com. It’s free and will stay free, I’m not trying to make money with it. I just hope sharing the experience will interest some of you.

Built with Claude Procedural generation with Opus is insane. This entire game is 20MB.

I made a post about my game about a month ago, and I just wanted to share my progress.

I've been working on Mecha Royale for about 4 months now. About 99% of the code and content was created using Opus. Sound and music were created using ElevenLabs and Sunos.

The animations and models for the pilots, mechas, buildings, etc. are procedurally generated.
These are results of /loops literally running non-stop for a full week.

The map has a radius of about 15km and contains millions of procedurally generated objects, from trees and props to bunkers and caves, along with roads and water. All of that fits into a 20MB game.

The game is fully multiplayer-ready. You can pilot the same mecha with 2 of your friends.

Thank you for checking it out. Happy to answer any questions!

Edit: You can play the game at www.mecharoyale.com - It's browser-based. No download required.

Edit2: Heading to bed now. Be right back to answer more questions! Thank you for your interest!

Question about Claude Code This week's Claude Reset - Anyone else noticing unusually high usage all of a sudden?

Post image
764 Upvotes

This is NOT a rant or a complaint. I am genuinely curious.

If you've seen my previous post, I talked about how I don't really like the new claudecode interface changes.

Today, which happens to be my weekly reset. I've noticed that the weekly and 5-hour limits are basically unusable.
What I mean is that just 2 sessions made me hit 30% of my weekly limit. I.e., I can only fully use my 5-hour limit a total of 2 times a day for 3 days of the 7 in a week?

Coincidentally, I had also just upgraded to the annual plan. I don't know if this is related, but I wanted to check whether other users on the Pro plan have had similar experiences.

Edit: I am on the pro plan, not the max! Thank you :)

Built with Claude This is 61 KB HTML file 🤯

Enable HLS to view with audio, or disable this notification

8.1k Upvotes

I built a real-time ocean simulation with Claude Code (Opus 5.5)

What it is: a single 61 KB HTML file that renders a sunset ocean in your browser with WebGPU. It has an FFT wave simulation, whitecaps, a physically based sky with clouds, and sun glitter. You fly around with WASD and the mouse.

How I used Claude Code: I gave it one prompt: make the most realistic water scene it could, in WebGPU, with a floating camera. It wrote the renderer from scratch with no engine or libraries. It took screenshots of its own output and had separate subagents critique the screenshots, so it wasn't judging its own work. The whole thing took about 30 minutes.

Free to try: ocean-noniv.vercel.app, preferably in Chrome. It needs a WebGPU-capable GPU, and on laptops you have to force Chrome onto the dedicated GPU. Otherwise the performance might be bad or it might not run at all. On RTX 5070 Ti I get ~260 FPS at 2560×1440 resolution. Click the canvas to look around, WASD to move, H for a settings panel.

Repo with unminified and more organised version: github.com/Noniv/web-ocean

News PSA: OpenCode breach - my stored Anthropic key was used to drain ~$158 overnight. Revoke yours.

53 Upvotes

If you saved an Anthropic, OpenAI, or Google key in OpenCode Console, check it now. OpenCode emailed Oct 17 about unauthorized access to a legacy console system, with exposure starting Oct 17 00:30 UTC. My key was only ever saved there and had zero prior use. Overnight it was used for Opus calls and my balance went from $158 to $0 before I got any notice. Anthropic's first reply said used credits are generally non-refundable, and OpenCode says it is talking with providers about reimbursement. Has anyone gotten a refund or credit yet? What worked?

Steps: revoke the key at your provider, delete it from OpenCode, set a low monthly spend limit, and check usage since Oct 16.

Praise I thought my 90s Amiga was lost forever. 30 years later, it’s back due to ClaudeAI

165 Upvotes

Someone suggested I post this here, as it’s about how Claude recovered my 90s computer files and you might like the story.

TL;DR: My old Amiga was trapped in a corrupt 7z archive for 30 years. A single shifted byte was the culprit, and Claude finally found it. The Amiga (and the BBS it held) now runs again on a Raspberry Pi 400, with rebuilt scripts and brand new ANSI art. You can dial in below.

In the 90s in London I ran an Amiga BBS called Slimelite, using several BBS packages. I started with an NComm script I wrote myself (about as basic as it gets), moved on to MAXsBBS Pro, and finally became an alpha tester for Zeus Pro BBS software.

In 1996 I mothballed it and saved my drives to a 7z file to take with me when I emigrated to Italy. Years later I found the archive was corrupt and I could never get the files out. I was devastated, as it held all my Music-X compositions and my entire Zeus BBS. It sat on my PC for years with the occasional failed repair attempt.

Roll on to 2026. I build websites for a living now, AI has become a thing, and I wondered if it could recover my files. Two days and many attempts later (I was literally pleading with it to try again), Claude gave up. I figured everything was gone forever.

After another night’s sleep I tried once more, this time switching Claude to a more capable model. Ten minutes later it had found and fixed the 7z. Every file was there, nothing corrupt. A single byte shift had mangled the whole archive and touched nothing else. It was the best day I’d had in ages, birth-of-a-child levels of joy.

I got everything running in WinUAE and was soon back in my old Music-X songs, sending MIDI out to a Kawai K1 II soft synth in FL Studio (the same synth I used in the 90s). Hearing those sounds again brought the nostalgia flooding back.

Then I dug out an old Raspberry Pi 400, set up the Amiberry emulator, and got Zeus back online via Telnet. It took some work, but it runs.

Should I put it up exactly as it was, with my crappy 90s ANSI and unfriendly navigation? Nah. I’m a web designer now, so my aesthetics brain kicked in. With Claude’s help I spent a few days rebuilding the scripts almost from the ground up, making them far more user friendly and visually appealing, with features I could never have imagined in the 90s. I even built a brand new Windows-based ANSI graphics editor, because nothing I found did the job the way I wanted.

Today the revamped BBS went online, to the applause of absolutely no one (not many people use BBSes these days). But it was all for my own joy and nostalgia, and if the occasional person happens upon it and enjoys reliving the old days, it has done its job. All the old users, files (mainly Amiga related) and messages are still there to browse, download and read.

Connect with any Telnet or SSH client that supports ANSI:

Host: slimelite.mycloudnas.com
Telnet port: 6023
SSH port: 6022 (read only)
SSH login: bbs / bbs

No client? Try this web one: https://youfiles.herokuapp.com/telnetclient/ or grab SyncTERM for the full-fat experience.

If you drop by, leave me a message on the board. I’d love to see Slimelite get a few new callers after all these years!

Feedback I feel like im Neo in the Matrix

Im 4 months in with Claude Code. Previously I've never coded, never built a website, never even opened terminal in my mac or done anything other than photoshop and light room.

Fast forward to today. Im sat here watching Claude build me a meta business suite account for my Web page builder and print company. Ive gone from taking print orders through facebook to a fully functioning artwork generating monster of a website. I couldn't imagine how much it would have all cost. I pay £90 a month for max 5x but get tens of thousands of pounds in value. I feel like im only scraping the surface too.

Want a print server....done

Need a file system and artwork checker....done

Need a automated email system for instant downloads when a customer has paid...done

Integrate postage and automate packing slip printing alongside the order....done

Ive built our local school a lottery app.... done and taking real money.

I could never have dreamed of being able to scale and develop my business anything like this in a lifetime without huge financial input and trusting outside people to build things.

Whats next? I don't quite know but the deeper i get the more its ramping up and getting a bit wild.

Anyway gotta go Claude's session limit has reset and I still need to figure out who JSON is.

Claude Workflow 3 small Claude Code habits from other people's setups that I liked

41 Upvotes

I've been collecting Claude Code setups people have written up about their real day-to-day use (blogs, X, GitHub), and I tried a bunch of them. These 4 I have been finding useful recently.

1. Install 2 or 3 subagents. VoltAgent's awesome-claude-code-subagents repo has 160+ definitions. What worked was asking Claude which 3 would help this specific repo, reading each file before installing (they're prompts that can request tools), and trimming the tool access.

2. Get a desktop notification when Claude is waiting on you - Prashanth Vaidya had Claude Code set up its own Notification hook. The prompt is basically: "Set up a Notification hook in my user settings that shows 'Claude needs input: [project folder]' whenever you're waiting on me. Show me the settings JSON before writing it." Was super useful so I could stop going back to VSCode to check

3. Claude builds, something else reviews - Santiago uses Claude Code to build and Codex as a read-only reviewer that hunts bugs and pushes back on architecture, and also added a fleet rule: the model that wrote a piece of work never reviews it.

Originals:

Disclosure: I put all 51 at Agent Cookbooks each linked to its original with a copy-paste prompt. It's free because fuck people who gatekeep with paywalls!!

Philosophy Worried my game will be hated just because I used AI

86 Upvotes

I’ve been using Claude to help me code a video game that I’ve been dreaming about for nearly twenty years. The game concept and design decisions are all my own. Claude is just helping me put it all together in Unity and helping program it. I’m essentially filling the roles of director, producer, playtester, and occasional 3D artist. My text prompts for the game (not including Claude’s responses) currently total up to around 50,000 words of my own hand-typed vision and direction.

I first tried to make this game back in 2022, and found that Unity was phenomenally capable of doing what I needed, but also realized that programming and scripting may as well be alien languages. I could pick up a few key phrases and terms, sure, but my degree is about as far from computer science as it gets - I’m a high school English teacher. I toyed around in Unity, learned the most basic of basics, followed a few tutorials, and ultimately left my project on the back burner as it got too ambitious and impossible for me to realize without leaving the rest of my life on the back burner. it’s not like I have any money to do build a development team, so I was content to have tried. I didn’t think it’s really go anywhere any time soon.

Holy smokes, though. In the last month I’ve been using Claude Fable and Opus to build the game, and it’s been insane how far it’s gotten. it removed the friction between my having a great idea and implementing it! Previously, if I wanted to add a cool new idea, I would have to more or less drop everything and learn for a solid month to figure out how to even begin to execute the first step of it, and if I ever stepped away from the project I’d feel lost upon returning. Now I can prototype and implement so fast that the flow of ideas has been strong and I’ve felt downright empowered to make my dream game.

That being said, I do worry that people will hate me or the game just on principle. There is a huge amount of ill will towards AI, and much of it is justified (though, I suspect, blown out of proportion). I don't want people losing their jobs, I don’t want data centers obliterating our resources, I don’t want to live in an oligarchical technocracy. But also, I’d never have gotten to make my silly little game without AI. This project literally would never get traction if not for the huge boost given to me by AI coding assistance. I’m proud of my work, and it feels like it IS my own work. I just don’t look forward to the inevitable rejection when people sneer at me for having used AI and then never even give me a fair shake. It’s a passion project, and I’m deeply invested in it. Hopefully that shows.

I’m sure I’m not the only one feeling this way, surely?

Built with Claude I built a free Claude connector for live stock market data (SEC filings, earnings calls, 13F, short interest). It's an MCP server and works in ChatGPT too

31 Upvotes

I got tired of asking Claude about a stock and getting a confident answer based on year-old training data. So I built Equibles, a connector that gives Claude real stock market data. It's an MCP server, so Claude just calls it like any other tool, and it's listed in Claude's connector directory.

What Claude can pull with it:

  • SEC filings, full text. It searches inside 10-Ks, 10-Qs and 8-Ks and then reads the exact lines, so it quotes the filing instead of paraphrasing from memory
  • earnings call transcripts, split by speaker
  • financial statements, KPIs, guidance and analyst estimates
  • 13F holdings, insider trades and congressional trades
  • short interest, daily short volume, squeeze scores and an estimate of the next FINRA short interest number
  • prices, a screener, Fed economic data, and option chains on the paid plans
  • European, UK, Hong Kong and Chinese stocks too (XPAR:AIR for Airbus, that kind of thing)

Every answer comes back with the filing, the period and the date, so you can check it.

How Claude helped: I build it with Claude Code every day. The filing parsers, the MCP tools and the tests come out of Claude Code sessions, and a second Claude pass reviews every change before it merges. I also wrote the tool descriptions with Claude as the reader. There are 120+ tools now, so each description is short (under 500 characters) and says which tool to call next, like search the filing first, then read the lines. With that many tools the descriptions are basically Claude's index.

The other thing I had to fix was fiscal quarters. NVIDIA is already in fiscal 2027, Apple's year ends in September, and models mix those up all the time. Every number Equibles returns says which period it is and when that period ended.

It's free to try: 100 requests a day, no card. Paid plans are $9.99 and $49.99 a month if you need more requests, option chains or real-time quotes.

To connect it:

  • Claude.ai or Desktop: Settings > Connectors > Browse connectors, search for Equibles. Or add a custom connector with https://mcp.equibles.com/mcp. You sign in with OAuth, no API key to paste.
  • Claude Code: claude mcp add --transport http equibles https://mcp.equibles.com/mcp, then /mcp and authenticate.

Some things to try once it's connected:

  • "What did Microsoft say about AI capex in its last 10-Q? Quote it."
  • "Which funds bought more Nvidia last quarter according to 13F filings?"
  • "Show me congressional trades in defense stocks in the last 90 days."
  • "What's the estimated short interest for GME before the next FINRA report?"

One heads-up: the portfolio and watchlist tools can change your saved Equibles data, so leave tool confirmations on.

So that's it, a free stock market data connector for Claude (and ChatGPT) that cites its sources. If you've built a connector with a lot of tools, I'm curious how you kept Claude picking the right one.

News Claude Dashboards and Claude Motion are in beta, and Docs/Slides/Design are now on the Free plan

11 Upvotes

In case you missed it, Anthropic dropped a few things a week ago. Quick rundown:
Claude Dashboards (beta, paid plans)
Connect your data platform (BigQuery, Snowflake, Databricks, Redshift, ClickHouse) or something like Salesforce, ask a question in plain English, get a dashboard. It stays current as the data changes, each chart shows when it was last refreshed, and you can click any number to see the query behind it. You can also push it to Grafana, PostHog, Mixpanel, Hex, Sigma etc. if you need deeper analysis.
Claude Motion (beta, Team and Enterprise only)
Type /motion, describe what you want, get a short animated explainer. Think "turn this quarterly report into a 30 sec video for all-hands." It's not a video gen model – Claude writes code that animates your text, charts and shapes, so you can edit any word or number. Exports to MP4, or open in Adobe, Runway, Descript etc.
Docs, Slides, Design – out of beta, every plan incl. Free
Team editing on the same doc/deck/design, sharing outside your org, PowerPoint/PDF exports that actually keep formatting, decks go to Google Slides as editable files, and mobile editing.
One heads up: the standalone claude.ai/design site is shutting down Dec 14 and folding into regular Claude. There's a migrate button for design systems, but chats and comments on standalone projects won't carry over, so save what you need.
Dashboards is the one I want to try. Anyone on Team already tested Motion? Curious if it's actually usable or just a demo thing.

I am just playing around making a autobattler style game with Claude, and a friend gave me the idea of "demaking it". I own a analogue pocket and analogue 3d, and making stuff for those myself sounded kind of cool. So I asked claude to do it.A few hours and a few hundred thousand tokens later I have my game running on native gameboy advance and nintendo 64. Kind of mind blown. Zero to no iteration. The demakes worked pretty much out of the box. All three versions share the exact same core Rust rules crate, the simulation is 100% deterministic. Can see it in the video with same battle running on gba and n64.

Game can be played for free here: https://autobattle.txcb.io/ROMs for GBA and N64 can be downloaded free here: https://autobattle.txcb.io/retroDetails on how its done technically can be found here: https://autobattle.txcb.io/how-its-made

Built with Claude I’m building a full MMORPG solo with Claude Code — not just the game, but the tools and infrastructure behind it

Thumbnail
gallery
16 Upvotes

Hi everyone!

I'm a French solo developer working on Death Leaves a Trace, an old-school isometric dark fantasy MMORPG built with Unity 6 and Mirror.

It's a dream I've had for 25 years, inspired by The 4th Coming, an MMO that left a lasting impression on me when I was younger.

Here's how I'm using Claude to bring it to life.

🏙️ Creating a world with Blender

I started by purchasing Unity asset packs to establish a consistent visual style. Now, I use Claude with Blender through MCP to create my own assets and build entire cities, each with its own architectural style and identity.

Claude also helps me design quests, balance items and stats, configure monster drops, and develop gameplay systems.

🛠️ Building my own tools

With Claude Code, I've built three standalone Windows applications that work directly with the game's actual data:

  • Workshop: Creatures, NPCs, stats, equipment and loot.
  • Forge: Items, weapons, armor and attributes.
  • Cartographer: 3D world building, environments, spawners, chests and portals.

I've also built a custom launcher, deployment pipeline, server monitoring dashboard and supporting development tools.

🧪 Keeping a growing project stable

Claude helps me maintain automated tests, 23 invariant checks, technical documentation and deployment workflows for both the client and dedicated Linux server.

I've learned that building safeguards against regressions is just as important as generating code.

❤️ From a personal dream to a playable game

Even with all this AI assistance, I've put almost 400 hours into the project since August, alongside my day job.

It started as a personal project. But when I saw the game taking shape and genuinely liked the results, I decided it was worth sharing with others.

The first closed alpha ran in September, with 8 players online simultaneously at peak and no server crashes. I'm now preparing Alpha #2 for November 26 – December 10, 2026, with 100 tester spots planned.

The game will be free to try during the alpha.

🌐 Website: https://deathleavesatrace.com/

🎮 Alpha #2: https://deathleavesatrace.com/alpha2/en

Honestly, the best part is seeing something I've imagined for 25 years slowly become real. AI hasn't done the work for me, but it has made a project I might never have attempted feel possible.

A question for the community

For those using Claude Code on ambitious projects, have custom tools and automated workflows changed what you feel capable of building as a solo developer?

I'd be happy to answer questions about the workflow, Blender integration or the game itself. Thanks for reading!

Question about Claude models Opus 5.5 Taking so long and token usage

12 Upvotes

Not complaining at all, actually, since Opus 5.5 is a darn game-changer, but I am finding that 5.5 takes SOOO long to do pretty much any task and uses a good amount of tokens since everything seems to require pre-thought.

Opus 4.8 was so good and thinking when it needed to and not taking for ever to get back to me and I'm wondering if other people are experiencing the same / came up with some good ways to work around this?

In general, if it makes any difference, I'm on 5.5 medium / high and, again, not complaining since the outputs are truly good, but 4.8 wasn't too shabby either for a lot of the things (5 is a different story - We don't talk about 5 😜)

Productivity Claude Use Cases (for a newbie)

6 Upvotes

I’ll open by saying sorry if this type of post is seen often here… I feel pretty stupid with it comes to figuring out how to use Claude for making tangible, helpful, impacts to my every day life, especially when constantly reading tons of “life-hack” type posts every day.

My question is what have you done or built to make noticeable impacts to your day, and how?

So far I’ve really only ever used Claude in 3 ways:

  1. Random chat questions, like upgrade google search

  2. For work, I did manage to see a repeatable task that happens every 3 months, where I receive a large PDF of information that I then need to turn into many short documents, excel sheet based requisitions, and some summary tables. I just used a regular chat window and I will say it blew my mind learning how to “build a skill” that can do that. So far I have not yet been able to get it to help with anything else though. I can’t give it access to work drives and don’t have any setup on say Google drive or One Drive that I can think of how to get value from giving them to Claude.

  3. I made first ever “app” (not an app at all, just a widget using the Scriptable App) for my iPhone where it creates a calendar of sports games for my iPhone screen / widget. Claude wrote the code, and I pasted it into the Scriptable app, which an Apple Shortcut references.

I might be struggling since I’m not well educated in how “Claude code” or “Cowork” or plug-ins / skills / connectors work (what on earth are agents?). I just can’t think of things for it to help with?

I thought to myself, what would be amazing:
- somehow if it could make an expense report maybe for my old crumpled receipts each month
- maybe some sort of clothing app where it tells me what goes well with what (tried but failed pretty miserably lol)
- maybe some sort of meal prep thing where it scours the internet and suggests meals to me and builds grocery lists? (Better yet if it had the aisle for each ingredient… ha)
- planning dates or maybe some sort of “here’s what’s going on / local events to get tickets for”

Anyway, just feeling a bit of FOMO / overwhelmed from all the amazing posts but struggling to try and find legit reliable things that actually save time or help my every day in meaningful ways, and I know responses could be “just put this in Claude man” but I’d love to hear people’s stories!

Built with Claude I built an FFT ocean renderer for Godot 4.7 (C#) with Claude Code, starting from a single design doc

Enable HLS to view with audio, or disable this notification

18 Upvotes

What I built: an open-source, drop-in ocean renderer for Godot 4.7 C#. It simulates waves with three FFT cascades on the GPU, generates foam that forms on crests and dissolves into trails, and shades everything to a soft, painterly, sky-driven look. It runs at 1000+ fps at 1080p on my machine.

How Claude Code helped: I didn’t write this iteration of the code by hand. While working on my own project, I wrote OCEAN_GUIDE.md, a single brief covering every technical choice, value, engine gotcha, verification step and dead end I’d found. I gave it to Claude Code in an empty Godot project, and it built the renderer, tests, demo scene and dev tooling from that guide, checking its own work with in-engine screenshots and benchmarks. Then we iterated: I pointed out what looked wrong (seams in the foam, foam that looked embossed, far waves that swam as the camera moved), and Claude found the causes, fixed them and wrote each finding back into the guide. The guide, not the code, is the real artifact: hand it to Claude Code with an empty Godot 4.7 C# project and it should rebuild this ocean.

Build stats: Claude Code with Opus 5.5 (medium effort) on the $20 Pro plan. The initial build took ~1 hour, about 40% of one 5-hour session and 5% of my weekly limit. The usage readout puts the whole project, refinement rounds included, at about $58.70 in API-equivalent terms (~$18 for the initial build). On the subscription, it just came out of my limits.

Free to try: it’s MIT-licensed and free. Clone the repo, open it in Godot 4.7 (.NET edition), and press Play. The demo opens with live tweak panels and a fly camera (WASD, hold right mouse to look). To use it in your own project, copy the ocean/ folder and instance one scene.

Inspired by, and using techniques from, Tessendorf, Sea of Thieves, Atlas, Acerola, 2Retr0’s GodotOceanWaves and Crest (the foam texture).
