I benchmarked three ways to do enum-to-string in C++26: the new reflection, enchantum, and a classic X-macro. Can you predict the winner? ⚔️ vittorioromeo.com/index/blog/r... #cpp #gamedev

Patch notes: - Fixed major issue where slider widgets were not affected by gravity. I sincerely apologize for this oversight.

Normal game developer: "I will add ImGui to display useful information and help me debug my game." Me:

C++20 coroutines have lovely syntax, but they're a terrible fit for games. Here's what I built instead: ~200 lines of stackless C++ coroutines that survive a quicksave/quickload.💾 vittorioromeo.com/index/blog/s... #cpp #gamedev

I made a mistake in my original benchmarks: the Docker image I used had internal GCC assertions enabled. I re-measured everything on a proper build, and times are ~50% faster across the board. The article has been updated with the correct data. I apologize for the confusion.

Fast iteration is the key to developer happiness. 🚀 I took a very early look at C++26 Reflection in GCC 16 to see if it would ruin my "fast compile" workflow. Here are my findings! vittorioromeo.com/index/blog/r... #cpp #gamedev #programming

What if... I combined #tetris and #vampiresurvivors? www.youtube.com/watch?v=Tb6d... #gamedev #cpp #sfml

Ever need a profiler but don't want the hassle of a heavy framework? I wrote about a simple, hierarchical #ImGui profiler I created for my projects. It's thread-local, has minimal overhead, and only ~500 lines of C++. Check it out! 👇 vittorioromeo.com/index/blog/s... #cpp #gamedev

I was incredibly fed-up with #powerpoint not supporting proportional text drag-resizing. So after searching hours for workarounds and solutions... I just implemented it myself 😎 #presentation #addin #office #microsoft #slides

If you're curious about how Boost.PFR works, this blog article explains the basics: akrzemi1.wordpress.com/2020/10/01/r... It's clever but not too crazy! I definitely see potential uses for it

I have created a self-contained version of my #cppcon 2025 keynote demo using @raysan5.bsky.social's excellent #raylib. The only requirement is CMake, all dependencies are automatically fetched. ➡️ github.com/vittoriorome... Enjoy! 🚀 #cpp #indiedev #performance #cplusplus #performance

My CppCon 2025 keynote is now available on YouTube -- eager to hear what you think! 🚀 www.youtube.com/watch?v=SzjJ... #cpp #cplusplus #gamedev #performance #sfml

I'm very excited about C++26 reflection. However, people underestimate what you can achieve *today*! Inspired by Barry Revzin's awesome "Practical Reflection" talk at @cppcon.bsky.social I wrote automatic Dear #imgui generation for structs, including labels! (via Boost.PFR) #cpp #gamedev

Reflection in C++26...? Who needs that! With some good old C++17 metaprogramming, you can get type-safe, refactor-proof Struct-of-Arrays transformations today😎 gcc.godbolt.org/z/sd7f4Mjx8 #cpp #gamedev #performance #HPC

🤔 What if writing faster C++ code actually meant writing *simpler* code? I'm incredibly excited to share that I will be giving my first-ever keynote at @cppcon.bsky.social 2025: ➡️ “More Speed & Simplicity: Practical Data-Oriented Design in C++” cppcon.org/2025-keynote... #cpp #gamedev #cplusplus

POV: You combine C++23's "deducing this" and C++17's CTAD to implement a vector iterator that propagates constness with no repetition (DRY). Can you spot the mistake? Every LLM seems to be fine with the code! #cpp #cplusplus #gamedev #coding

Unfortunately it's a #golang article but it's very valid for #cpp as well. KISS! rednafi.com/go/di_framew...

Is it possible to write a simple iteration API that hides implementation details *and* lets users `break` and `continue`? 🤔 Here's a new article about a lightweight solution using a `ControlFlow` enumeration! ➡️ vittorioromeo.com/index/blog/c... ⬅️ #cpp #gamedev #cplusplus

What is the proper way of ensuring non-exclusive borderless fullscreen on Windows + OpenGL? Using windowed + borderless flags in SDL still results in exclusive fullscreen: github.com/libsdl-org/S... How do most games implement this sanely? #cpp #gamedev #sdl #sdl3

globalgamejam.org/news/global-... So happy for my friend @vittorioromeo.bsky.social representing our hometown in the global game jam with his cute, little game store.steampowered.com/app/3499760/... #gamedev #gamejam #globalgamejam

Any #opengl wizard interested in helping me demystifying an incredibly weird bug where an innocuous `glGetIntegerv` call causes an unrelated assertion failure? 🤨 forums.developer.nvidia.com/t/weird-beha... #gamedev #cpp

Exciting news! 📢 I'm now offering bespoke C++ training, mentoring & consulting: romeo.training While current availability is limited (weekends/off-hours), I'm keen to connect with potential clients for future projects as my schedule evolves. RTs appreciated! #cpp

As part of my battle against long #cpp compilation times, I've opened a (work-in-progress) PR for Aras Pranckevičius's excellent ClangBuildAnalyzer to add an approximate origin of expensive template instantiations: github.com/aras-p/Clang...

Released a major update today, adding #speedrun mode to my #indie game BubbleByte! 🫧🐱 store.steampowered.com/news/app/349... Powered by Modern #cpp, #sfml, #sdl, and #imgui. Fully #OpenSource! #clicker #gameart #gamedev #idle #incremental #indiedev #indiegame #screenshotsaturday #towerdefense

Here's short #cpp article on a simple yet suprisingly effective implementation of automatic draw batching in my fork of SFML 🚀 vittorioromeo.com/index/blog/v... #sfml #gamedev #opengl #performance #indiegame #indiedev

The game my girlfriend and I made is going to be played live on stream for the first time -- hope it goes well!🤞 #screenshotsaturday #cpp #gamedev #idle #incremental #indiedev #indiegame #sfml #towerdefense #twitch

Reviews like this remind me why I pour my heart into #gamedev. Every late night was worth it. 🌙 #screenshotsaturday #indiedev #indiegames #indie #Steam #sfml #sdl #cpp

Today I released the first major update for BubbleByte, reworking prestige scaling and adding a new autocast option for the Wizardcat! (Pictured: the Wizardcat stops time 🧙) #screenshotsaturday #cpp #gamedev #idle #incremental #indiedev #indiegame #sfml #towerdefense @sfml.bsky.social

I did a quick test changing `float` to `_Float16`, and unless I screwed up, the results are very promising! 5M particles, multithreading on, rendering off, and repopulation off: - float: ~5.1ms (180FPS) - _Float16: ~2.15ms (380FPS)

Fellow fast #cpp compilation time enjoyers, has anyone figured out a way of defaulting C++20's spaceship operator (`<=>`) without having to include `<compare>`? At the very least, defaulted equality does not require the header...

Just published a short #cpp article that benchmarks the AoS (Array of Structures) layout versus the SoA (Structure of Arrays) layout in a 2D particle simulation. You can try out the benchmark right in your browser! vittorioromeo.com/index/blog/p... #sfml #gamedev #opengl #performance

Today I hosted a #speedrun tournament for my game, BubbleByte, at my local gaming hall! (Redshift Gaming) It was fun to see people play live, and a great source of feedback :) #clicker #cpp #gamedev #idle #incremental #indiedev #indiegame #sfml #towerdefense

Folks, what do you think is the best #Steam capsule art for my upcoming game? The main goal is get people to click, doesn't have to match the game's artstyle :) #cpp #sfml #gamedev #indiegame #indiedev #idle #clicker #incremental #towerdefense #gameart #screenshotsaturday #art

@ocornut.bsky.social's Dear #ImGui is a godsend. I'm debunking the myth that it can't create polished game UIs - my game looks & feels great with it. Today I added background/BGM selectors very easily! #cpp #sfml #gamedev #indiegame #indiedev #idle #clicker #incremental #towerdefense

I have added unlockables to 🫧🐱 BubbleByte! Discovering a unique cat will grant a background and BGM track. UI is also affected! What do you think? Are these small features worth the big effort? #cpp #sfml #gamedev #indiegame #indiedev #idle #clicker #incremental #towerdefense #cat #automation

I am beyond disappointed... I sent this DM in 2020 alongside an email to @nightdivestudios.bsky.social -- both got ignored. Since then I've worked on more successful VR mods (HL2VR Unleashed, Vertigo 2 Unleashed). I would have helped out for free as a passion project, and I'd still do it. 😔
