TELL ME AGAIN HOW GREAT BRITAIN WOULD BE IF IT WAS RULED BY THE MERCILESS JACKBOOT OF PRINCE CHARLES

coriolis acceleration should only take a moment to implement, if you're interested: taking the x axis to be pointing east and the y axis to be pointing north, you want a point with velocity (u,v) to experience an acceleration

4*Pi*R*sin(L)/T (v, -u)

where

R is the radius of the planet
T is the length of its day
L is the latitude of the point

this might produce some weird behaviour because the geometry you've got in that vid is of a cylinder rather than a sphere, but try it and see :)

if u calculate the rossby number for your flow you might get away with the geostrophic approx and save some calculating at the poles

rule #1 of fluid dynamics is to ignore as many terms as you can

how do u make youtube not turn your pixel-perfect simulation output into a lovely blurry mess

the red is supposed to be little vectors showing wind direction but instead they are blobs and streaks

for example here is what one of the frames is supposed to look like:

would you say you are pretty navier-stoked right now?

If you want something done, do it yourself!
i changed the colour of the vectors in hopes that something else would compress better than red (gently caress red forever) and rendered a 1080p version which looks a bit better

https://www.youtube.com/watch?v=mUJQnR1_oNU

i'm still playing around with the acceleration thing

eventually i'll stop using a cylinder and use something actually shaped like a planet

tases are designed to be repeatable on real platforms and great care is taken to ensure it to the point that people have modified n64 controllers to precisely play back the control inputs used in the emulator stage to a real n64 and then record that whole thing for verification

it mostly only matters when new glitches are discovered to verify that they are game glitches and not emulator glitches

yes, at least systems for which tasing happens. basically anything n64 and older.

i also hooked up buttbot to twitter and it hasn't been reported/blocked/whatever for nearly 3 years now :shrug:

my program just runs every 5 minutes or so, grabs stuff from the stream sample api until it succeeds (usually the first tweet is fine, but it'll keep streaming until it is able to process one), then reposts it, then quits and cron starts it up again later

i used to stream 24/7 but it was total overkill for something as low-volume as that

i also used to follow back anyone who followed it and use that to get tweets (using the api equivalent of the home screen), unfortunately it resulted in following like a thousand spam bots, poo poo source material, and me hitting the upper limit of how many accounts you can be following at a time (it's around 1800)

I guess twitter changed the rules since then. with what you said in mind these days I tried manually following people who followed the account and it got suspended again but this time it's not coming back anymore :(

put an entrance anywhere

since all rooms are accessible, any entrance into the building is a valid entrance

no, i spent today on it

the original engine did a shitload more, including a quad-tree rendering graph, scene graph, tetris-style inventory and minimap guis, a* pathfinding, npc state-machine ai, procedurally generated quests, paperdoll-style animation overlays for npcs, etc etc

but i coded myself into a corner so now i'm starting from scratch
