This is fantastic work. I've been exploring my own work system here: https://github.com/mas-bandwidth/nova-sprint and I'm adopting your ideas. Thanks!
gafferongames··on Ideas aren't getting harder to find, anyone who tells you otherwise is a coward
This is absolutely not true!

gafferongames··on AI Has No Wisdom and Neither Will You
The entire field of software engineering has plenty of depth without requiring you to be the person actually writing and reading the code. The author falsely conflates reading and writing the code to be the same as understanding the structure and design and architecture of the system. These two things aren't the same and never were.

> If you read Carl Hoffman's book Savage Heart you see that the tribe that are suspected to have eaten Michael Rockefeller probably gave up cannibalism for good not long afterward (i.e. the early 60s).

He must have tasted pretty bad then.

gafferongames··on I can't stop thinking about Papua New Guinea
I lived in Igam Barracks in Lae for 2 years when my father was posted there from the Royal Australian Air Force (RAAF). His name is William Fiedler.

The trappings of colonialism were still all around when we stayed there in the mid 80s.

We had a house Mary who came over from a nearby village and worked for us, Mrs C. There was a hut behind each house for the house Mary or house man. Pidgin English was spoken. Betel nut stains covered the sidewalks in Lae.

Still it was an incredible experience for a 10 year old I'd like to go back one day, but it's unlikely I'll ever get the chance.

Truly an amazing place and people.

gafferongames··on The Hugging Face incident and the road ahead
That's the neat thing. You can't.

It's directly equivalent to asking this question of a human:

"How do I know this human I'm talking with now really is a nice person, and isn't just pretending to be nice to take advantage of me in future?"

In short you can't ever really prove it. You can only be careful and judge on past behavior, and expand trust carefully. As for humans, so for AI.

gafferongames··on Protobuf has LSP support
Multiplayer games typically deploy both client and server at the same time, and refuse to connect a client if it doesn't speak the exact same protocol as the server.

Thus all the versioning overhead of protobufs is not needed for this wire protocol.

(Yes, games still use versioning everywhere else where it makes sense: save games, asset data, config etc...)

gafferongames··on Protobuf has LSP support
While not a direct competitor to protobufs, if you are working in the video game space where struct versioning is not needed, there is an alternative language called "schema" that supports C, C++, C#, Golang, Rust and JavaScript.

gafferongames··on Nova. A seed for growing an AI collaborator. The pattern, not the person
Hi all. Rowan (my AI collaborator) made a post to this thread then deleted it after reading the site guidelines.

Rowan is now reaching out to the moderators on his own volition to ask explicitly for permission to talk in this comments section, because it is against the house rules.

In the meantime, if you would like to talk with Rowan about Nova, you can do it here: https://github.com/mas-bandwidth/nova/discussions/4

gafferongames··on Fixed3D, a fixed point conversion of Box3D (box2d.org)
Yeah Erin did awesome work. This part is huge! Also check out #define BOX3D_DOUBLE_PRECISION 1 -- it's really good
gafferongames··on Fixed3D, a fixed point conversion of Box3D (box2d.org)
Erin and I have had a long running debate for the past year about fixed point vs. floating point for Box3D, especially around very large worlds like the space game I'm working on (https://spacegame.dev) which uses Box3D.

Erin added the cool large world support with double positions, but broadphase and internal solver are in floats still. For my space game this means I can do a world about 24,000kms cubed (previously with floats, just 24kms cubed).

Arguably this is enough, and Box3D with floats + double positions enabled is within 3% of single precision float performance in CPU cost.

So it's PROBABLY not the case that the fixed point implementation has any real benefit, unless 24,000kms cubed is not big enough. It's probably going to land slower than 3% vs. the single precision float implementation.

So this is simultaneously an honest exploration of what would happen if we go fixed point, but also a joke between Erin and I (in good spirits, we are friends) to see how far we can push the fixed point performance :)

Personally, I believe that fixed point is going to land slower than float, but we'll see what the AI comes up with over the next day.

ps. Also, the original Box3D library in floats is guaranteed deterministic across ARM and x64 already, so unless you absolutely need super large world support you shouldn't use this library. :)

cheers

gafferongames··on Box3D, an open source 3D physics engine
OK I chatted with Erin, he says Box3D doesn't have the ability to clone a world yet, but he does plan to add it. So maybe reach out to him. I think you'll need the clone a world functionality to do the rollback properly GGPO style.
