how to detect if player hand facing palm down

[wintry hazel]

Never done hand stuff, but you could get the up vector or forward vector and see if its greater or less than y = -1 via vector create, i say either or bc its a negative, so not sure. And im aware that like, both hand up and forward probaly dont exist as chips, so you find it with some math, ive seen some around in posts, so maybe look up "hand", "hand up vector", or "hand forward". Try the more straightforward searches and then move on to the broader one like "hand"

[naive tinsel]

This system wont work because the up vectors are different on both hands @willow tinsel @wintry hazel

[wintry hazel]

on both? What type of pivot setting is rr doing xD

[naive tinsel]

Instead

Rotate (1,0,0) by the left hand rotation, and dot that with (0,-1,0)
Rotate (-1,0,0) by right hand rotation and dot that with (0,-1,0)

[wintry hazel]

honestly tho, just look at cv1 pivots, official inventions and theyre trash 💀

[naive tinsel]

Forward = Finger Direction
Upward = Thumb Direction
Right = you suck (probably RR's words)

[wintry hazel]

ohhh xD i forgot about that, i thought they would just make hand constants and then u could use get position, get forward and everything like normal

[naive tinsel]

hand constants are stupid

they piss me off when I see them

I dont want "Finger and thumb" directions, I want forward, upward, and right

They are the same thing, just stupid names

[wintry hazel]

Right could be cross tho? RIGHT? xD pun

[wintry hazel]

yee

[naive tinsel]

Try using quaternion dot

it was a joke

[wintry hazel]

wait, if thumb is up, than cant you cross the finger and thumb to get palm?

[naive tinsel]

On your left hand yes, but cross method sucks because more CPU

[wintry hazel]

4D rotation to represent 3D rotation go brrrr

[naive tinsel]

|Quaternion Dot((Hand Rotation * Rotational Offset) * (Quaternion Normalize(Quaternion Create(0.Local Camera Rotation.Y,0,Local Camera Rotation.W))), Desired Rotation)|

How I check what direction your hands are facing in my magic game

[wintry hazel]

ah, so than scale the cross for the right hand by -1 (if using cross) Which i mean, how much more cpu we talking tho? just math, can't be too much

[naive tinsel]

no, ffs just rotate (-1,0,0) and (1,0,0), its cheaper and better

you could do that, just, dont

[wintry hazel]

ffs?

[naive tinsel]

for fuck sake

[wintry hazel]

ah mk xD

[naive tinsel]

except I feel "ffs" is a little more friendly, despite being same words in an acronym

[wintry hazel]

what about iirc? i see that alot too

[naive tinsel]

If I recall correctly

AFAIK = As far as I know

[wintry hazel]

ah mk xD

[wintry hazel]

i haven't had a phone all my life till almost a month ago xD

[naive tinsel]

damn

[wintry hazel]

so, almost 2 decades xD

[naive tinsel]

does that mean your 18~ or 22~?

[wintry hazel]

19

20 dec 16th

[naive tinsel]

damn

I had a computer when I was 3

and yet my parents didnt trust me with a phone till grade 6

[wintry hazel]

that explains it xD

[naive tinsel]

im 15 now

[wintry hazel]

o, bruh

ye thats cool

[wintry hazel]

be glad you got the privledge of the information your able to obtain today, and the privilege to be able to learn what its worth befor u completely neglected it like i did, thats y im so trash at math, all that came to mind was "this is only usfull if i wanna be a construction worker" so threw all my text books out n crap, hold on, and make sure u write everything down, never kniw when your going to need it

[naive tinsel]

People going "When am I ever going to use A^2 + B^2 = C^2?"

game devs:

[wintry hazel]

literally xD

i wanna go back and recreate all the math i was tought so i can visualize and undertand it better, teachers seriously underestimating how good coding can be, not only to understand things, but to get students interested in it bc then u can make games n such. I emailed my math teacher that HSV to RGB and he even had no idea how to read it

[naive tinsel]

"HEY YOU CANT USE A CALCULATOR!!!"
"this calculator is helping my visualize the math? i dont give a shit about the answer, im trying to find out how this equation works"

which is why I send people visual demonstrations in desmos when I can

[wintry hazel]

yee 😄

[wintry hazel]

The schooling system is decades old, you'd think they'd get a clue that not everything is perfect, and how change is a good thing, yet they just wanna put a buncha stress on kids with homework and blindly tell them about equations once maybe 3 times. And then they wonder y every kid (at least when i was in school) says they memorize it all instead of understanding it

[naive tinsel]

"maybe 3 times"

my school says "we are learning about absolute value" and then prints a 300 page worksheet we need to fill by next week of "|1 + -4|" type of math

grade 9 btw

grade 9 and its single digit addition

[wintry hazel]

oh xD well, thats still like, memorization, doing it untill its exercised enough in there. But yeah, very unecessary, if only they had u actually learn it

then they would be saying u have to do that crap, 300 pages long xD thats literally crazy. I dont get the school system at all

[naive tinsel]

"cmon the math isnt that hard, just do it"
"You think im struggling because its hard?"

• me after sitting down for an hour doing the most repetitive math equations in existence, only on page 3
