Found this video (may 2024) of me totally realistically playing the piano and I felt a need to share it. Apologies to all actual pianists.

Thank you for your kind message! Your game looks great. You can post this shot (or anything you like) in the Gallery, and I showcase some of them in release notes.

dampf: Old-school Steam skin for Dear ImGui A 2004-era Steam/VGUI2 tracker skin for Dear ImGui

i've been fiddling with an old-school Steam skin for Dear ImGui: seidt.quest/s/dampf/. i open it several times a day to click and drag stuff around therapeutically because it's… grounding? :D imgui gallery thread post with source and references coming.

I noticed a few maintainers e.g. ghostty saying they were flooded by LLM aided reports. I don't think I've got _any_ in the past few months, so I wonder if my github/template setups currently prevents them, or if somehow my audience differs enough to not attract those.

Totally agree with the later. Sometimes I feel sorry when competent programmers spent time making extremely an zealous report although their 1st sentence conveyed enough information to understand/fix an issue.

Whereas less skilled ones are frequently omitting useful info or drowning them in noise.

I haven't been bitten by AI issues/PR yet but if it happens I'll happily reuse that sentence you added to your template.

Thank you Alex! and for being the instrumental nudge in getting this library released, too :)

10 years of Dear ImGui (long post) · Issue #7892 · ocornut/imgui 10 years of Dear ImGui 🎉 On August 11, 2014, I published v1.00 of Dear ImGui on GitHub. I thought I would take the occasion to reflect about it, share some data points and stories, and generally th...

The opposite happened with PixelJunk 4am during its first half of dev: lacking a focused direction, for a few months I went on a tooling procrastination spree which ended up being defacto R&D on evolving the IMGUI impl at Q-Games and growing my interest in it (mentioned @ github.com/ocornut/imgu...)

Making Video Games in 2025 (without an engine) Thoughts, tools, and libraries I use to make games

lovely old article by @noelfb.bsky.social is on the-orange-site www.noelberry.ca/posts/making... love it! one thing that struck me (re)reading it was that your goal makes a HUGE difference: are u making your own game tools *to make a game you have in mind* or *to make your own game tools*

After my school-project "engine" went this way (fantasizing "all the potential for future games!"), for my subsequent project I remember making a conscious decision to not give a name to the next engine in order to not get too attached to it. The folder was called "core/".

His interactive imgui_manual also got improved and rebranded as 'Dear ImGui Explorer' pthom.github.io/imgui_explorer
It's a web build of the Dear ImGui Demo w/ source code displayed for whichever section you are hovering.

Last weekend I refined the scene tree view in Workbench. I used the drag & drop support in dear imgui to implement DAG reordering and reparenting, plus renaming. Custom behavior and drop region draw to show where the node would be inserted, and display where and why it cannot.

I do not! But please post to Gallery and sources would be nice. As with the Win98 and TUI hacks, I'm interested in this sorts of hack because when it comes to redesigning the style system I'll want to stress its features against being able to do the same with code changes.

you should be able to scale dynamically which will facilitate experimenting with it and fix things
