I made it so I can save chalk drawings at runtime back to the editor, meaning I can author chalk drawing assets for the game world from within the game world.

update on my Slime game💚

The dungeon's popularity is plummeting! Only the Slime can make it fun again. Lots of magic sodas are needed to get the job done.

Freya's notes on 2D quaternions, showing how to rotate a vector using a 2D quaternion, which has one real aka. w-component, and one imaginary component. This is basically a complex number, which you can already use for rotations directly, but with extra steps to ensure you have double-cover (which is generally just a nuisance). So yes this is a shitpost but it's also real functional math/code lol

are you tired of using a simple angle for 2D rotation?

are you missing that sweet double cover from quaternions?

well look no further!! introducing:

🎉 2D quaternions 🎉 😎😎

VR chopsticks! Always wanted to add these to a game, and now I finally can. I might be a bit biased, but they feel great! Effortless to use.

VR Vet Simulator? 👀
This was a fun setup to test my finger posing system on dynamic physics-based objects for Hand Physics Lab 🙌

Half-Life 2: 20th Anniversary Documentary

Amazing documentary released by Valve on the development of Half-Life 2, definitely worth watching!

a color coded image by Freya, comparing the summation and capital pi notation in math, to their equivalent in code using for-loops. The summation notation sums a set of elements, while the product notation multiplies a set of elements. 

Note that Freya is keenly aware that neither the math notation nor for-loops are fully explained by this image, and that this is only a subset of the use cases, so luckily you don't have to explain that to her, in case you were considering doing that!

btw these large scary math symbols are just for-loops

Half-Life 2's 20th anniversary update is out, episodes were merged into the main game, and added workshop support.

It is also free to keep if you get it until 18th.

I used the Quest Pro as my main dev headset for almost a year for it’s comfort and ease to put on and off.
Currently using Quest 3 but not really happy with it for development 😅
Desperately waiting for a best alternative for development

Hi Bluesky, I'm making Full Fathom. A horror adventure game, thalassophobia sim, and my passion project for the last 2 years.

If piloting a deteriorating submarine seems like your thing, here's the demo/wishlist link:

Hey all! 👋
I have a deep passion for building XR interactions using physics. 😄
You might now me for being the creator of Hand Physics Lab, Surgineer and Holoception.
Former Neuro/Bioengineer turned into an XR Developer as part of my journey as co-founder and CTO of Holonautic for 6 years now.

Screenshot from my untitled penguin VR project, with the player penguin holding a fishing rod and a Godot plushie. An NPC penguin in the background looks at the player.

Hi BlueSky! I'm a veteran VR dev (Job Sim, Vacation Sim, Rick & Morty VR, etc.) working on my first indie VR game!

Now that I'm quitting Twitter where I posted all my work, here's a thread summarizing the journey so far, for those who aren't familiar. 🐧🥽🧵👇
