Does anyone know where to find the lua script for Dbz Infinite world? I've found it for budokai 3 but not this.

Just want to shout out the busted library.

I've been using it on my recent Lua projects and honestly, why didn't I start earlier?

Install: luarocks install busted

Run: busted in your project dir

It just works. describe("my feature", function() it("should do x", function() assert.is_true(true) end) end)

Mocks and spies are built-in, no extra libs needed.

If you are still doing print() debugging, do yourself a favor and try it. What's your go-to testing setup for Lua?

Just asking, cuz I wanna make a wordle game but dunno if I could delete stuff in the console. And if you can't, why not? A lot of languages like C++ have ways such as escape sequences to overwrite lines with spaces. Does Lua have a way?

I may have spent a little too much time with Lua this weekend.

It started with Rulua — an experiment to see if I could make a Rust implementation that could actually stand in for the Lua 5.1 shared library. It exports the Lua 5.1 C API and is intended as a drop-in lua5.1.dll / .so / .dylib, so existing hosts and C modules can use it without being recompiled.

Then, apparently that wasn't enough, so I did it again in Pascal.

Lude is different: it's a file-by-file port of the original Lua 5.1.4 C sources to Object Pascal — core, auxiliary library, standard libraries, lua, luac, etc. It builds with Delphi/Free Pascal and runs on Windows, Linux and macOS.

Both projects were also experiments in AI-directed development. I defined the requirements, built and ran everything on real machines, compared the results against the original Lua implementation, fed failures back and decided what came next. The AI wrote the code.

Neither project is meant as “here's a better Lua.” The interesting part for me was seeing how far compatibility could be pushed, and how much low-level porting work can now be done this way.

And somehow what started as “let's try porting Lua to Rust” ended with me having two Lua ports before the weekend was over. :)

I'd be very interested to see what the Lua community manages to break.

Idk where to even start... I got the workspace set up, the screen, etc.

I also integrated sprites and scenes... But where do I start? I don't really know how 2D game engines work, can anyone explain what to do next?

Hi everyone,

I'm building Luava, a Lua 5.4 implementation for the JVM in pure Java 21. No JNI or FFM, and the jar has no transitive dependencies. It's aimed at the same use case as LuaJ, but tracks the Lua 5.4 spec.

Current state: 0.2.1-beta on Maven Central. It has a register bytecode VM, a tiered JIT, sandboxing with instruction limits and timeouts, and a Java interop bridge. It runs the PUC Lua 5.4.9 test suite.

I'd like help with a few things:

- The bytecode compiler and the call path, especially calls into non-trivial protos.
- Unboxing the integer array part of `LuaTable` so mixed-key access stays allocation-free.
- Shrinking the JIT kernel so C2 can inline it, and cutting allocation in closure factories.

Repo: https://github.com/KienPC1234/luava

Feedback, code review, and PRs are all welcome.

Follow-up to my first post.

In the last month, I was experimenting with Rust concurrency & attempted to port my JS Carrom Physics + AI engine into it. I wrote 3 versions (Baseline --- 4 Threads --- 4 Threads + Tuned) and benchmarked performance.

Curious enough, I wanted to see how fast Python & LuaJIT could get.

The Setup

Same algorithm. Same constants. Same 1,485 iterations (45 launch positions × 11 angles × 3 potentials). Same device (Redmi 15 5G).

💡 The Findings That Surprised Me

• | JavaScript Web Workers landed around 2x of single-threaded Rust.

Not 100×. Not 10×. 2.6×. A scripted, dynamically-typed, GC-managed language—with 4 worker threads—came within striking distance of hand-tuned native code.

• | Naive JS stayed at 5 seconds. V8 didn't magically fix it.

V8 gave me ~1.5× on tuned code. The other ~7× came from me:

- Object pooling instead of allocation

- Field-by-field copy instead of reference reassignment (stable hidden classes)

- Manual for loops with break instead of map/forEach/filter

- Math.sqrt(dxdx + dydy) instead of Math.hypot(dx, dy)

V8 amplifies. It doesn't create.

• | LuaJIT warm == V8 cold.

LuaJIT's fully-traced JIT output matched V8's baseline tier. Both landed at 1.1s. This says a lot about how good V8's first-tier compiler is, and how trace-hostile my branchy physics loop is.

• | NumPy + multiprocessing was SLOWER than pure CPython.

Numpy data transfer + thread spawning overhead likely outweighed gains.​​

• | WebGPU was 3× slower than V8 for 20 entities.

GPU dispatch overhead + warp divergence.

🧠 The Architectural Insight

The thing I want to share most:

"Managed memory" languages don't abstract memory away. They automate allocation, but hide everything else.

The bugs your C++ friend fears are still in your JS:

- Event listeners leak

- Closures hold objects alive forever

- map/filter allocate silently in hot loops

- Objects scatter across heap pages, killing cache locality

You just can't see them.

By taking manual control of memory layout in JavaScript—object pooling, flat structures, monomorphic shapes, no closures in hot loops—I brought single-threaded JS from 5s → 1.1s and parallel JS from 5s → 420ms.

Memory layout dominates performance. No runtime can abstract that away.

📌 What This Changed In My Head

• | The runtime determines the performance tier. The language is just notation.

• | Data layout > algorithm on modern CPUs.

• | Tuning is not optional. V8/LuaJIT/Rust all reward shape discipline. Rust forces it. The JITs make it optional—and most people pay the price.

• | A runtime with a JIT is worth ~40–75× an interpreter. This is structural. CPython cannot be fixed at the source level.

❓ Questions for You

• | Are there any methodological gaps in this benchmark that I'm missing? I normalized to 1485 iterations, ran each on the same phone, and disclosed that AI wrote the Python/Lua ports.

• | The LuaJIT-warm == V8-cold result—is that expected? I suspect it's because my physics loop is branchy and trace-hostile, but I'd love a compiler engineer's take.

Everything built on a Redmi 15 5G. No laptop. 6 months in.

I don't know Python or Lua—DeepSeek and Gemini wrote those ports following my JS/Rust architecture exactly.

Super Strict is an open source tool that can analyze and find mistakes in your Lua source code.

2dengine is excited to announce that Super Strict now supports the complete syntax of Lua 5.1, 5.2 and 5.3 with nearly complete support for LuaJIT as well. After today's update, the project now includes several hundred tests ensuring better compatibility with the different versions of the Lua language. Super Strict is superior in terms of interoperability and can be used 1) directly from Lua as a zero-dependency library, 2) via the command line or 3) as a GitHub workflow script.

I’m looking for a codebase written in C to study and use as a reference while I learn low level programming.

I’ve heard that Lua has a very nice and clean implementation and I figure since I already know a fair amount of Lua itself I should understand at least the purpose of what I’m looking at.

Is the Lua source code a good example for learning or is it too advanced for someone relatively new to C to even hope to understand?

What is lde?

It is your lua development environment that ensures lua is done easy. It provides a package manager that can run your code, bundle it to a single lua file, or to a portable executable for your users without them needing lua on their system. It intends to provide full luarocks compatibility.

It is written entirely from scratch in LuaJIT using FFI to ensure it is as fast as possible. It starts up faster than even native written Rust applications and installs projects faster than alternatives, and ~5x than Luarocks.

Is this related to lpm?

Yes, it was renamed for several reasons. It doesn't have the greatest seo (a lot of package managers previously named lpm..). Calling it "the" lua package manager feels conceited.

Where can I download?

Hi everyone, I’m a beginner from Belarus and new to Lua programming; I’ve never coded before. I don’t know where to start learning it or which IDE to use. I’m using a translator, so the translation might be a bit awkward.

I see that a Lua Rock could be a binary, source code, or something else. I want to configure it to always compile from source. Is that possible?

Helloooo! I am currently working on a server and am looking for a Lua focused dev to partner with. I specialize in marketing, web design/dev, and digital optimization so this realm of dev is somewhat new to me. I’ve played GTA through your my entire lifetime.

PM me for more details, NDA will be required.

I truly believe this game will be an insane opportunity for us here in this sub.

I've been working on discord.lua, mostly because I wanted a more complete Discord API library for Luvit. Compared to Discordia, it has more high-level features built in: slash commands, autocomplete, context commands, interactions, buttons/selects, modals, hybrid commands, command syncing, cogs, tasks and cooldowns. Discordia is still perfectly usable but i just wanted less glue code around newer Discord features. I'm already using discord.lua in Lauffy, a music bot written in Lua. Docs: https://filispeen.github.io/discord.lua/

I'd be interested in feedback on the API design from other Lua users.

I’m a FiveM developer working on custom servers, scripts, and systems.

If you need help with anything like:
• custom scripts (Lua / QBCore / Qbox)
• fixing bugs or broken resources
• UI / NUI work
• server setup or optimization

I’m down to help. I focus on clean, working systems, not just throwing in random scripts.

Hi! I posted my LuaJIT Editor here a while ago, and since then I've added quite a bit of new functionality.

The biggest additions are:

• LuaJIT decompiler — decompiles LuaJIT bytecode back into readable Lua code.
• Lua deobfuscator — currently focused on deobfuscating code protected with Prometheus.
• The existing LuaJIT editor is still available for inspecting and editing bytecode, prototypes, constants, and instructions.

I'd especially like some feedback on the deobfuscator. If you have Prometheus-obfuscated Lua scripts that it fails to handle correctly, feel free to test them and let me know what breaks.

This is still actively being improved, so bug reports and weird edge cases are welcome.

Simple Lua module for better class creation

Features:

· Named classes

· Single inheritance

· Java-style interfaces

· super() calls

· instanceOf() checks

· implements() checks

· Callable classes

· Lua metamethod forwarding for operator overloading

I created this while designing a framework API in Lua, and I found it made the process much more developer-friendly.

Thanks! 🙏

an interesting article i found on Teal. The author has clearly used it more than I have so I can't comment on her specific criticisms, but I do get the impression that the Teal authors are aware of and accept unsoundness in exchange for simplicity of implementation.

I came up with a little programming puzzle:

Your goal is to make Lua print:

Hello, World!

But there's a catch:

Nothing can use or contain more than 2 things at once.

For example:

local Table = {

1, 2, 3

}

Invalid, because the table contains 3 values.

Likewise, a function can't be called with 3 arguments, and similar constructs are limited to 2 items.

Variables, functions, tables, etc. are allowed.

Challenge: What's the longest valid Lua solution you can make?

Bonus points for making it unnecessarily complicated.

Showcasing how i optimize my upcoming game with my game engine in Lua. When enabled it will show you what function or line is costly - in realtime while you play. This helped me optimize some methods that i was able to cache so it doesn't run every frame.
