how do i detect what direction a player is swiping relative to them? | Rec Room | Page 1

#

how would i?

fading dirge Jan 31, 2026, 5:42 PM

#

sullen acorn how would i?

define "swiping"

sullen acorn Jan 31, 2026, 5:42 PM

#

like hand velocity

#

like swiping a sword right

fading dirge Jan 31, 2026, 5:42 PM

#

do you need the detect direction of the swipe?

sullen acorn Jan 31, 2026, 5:43 PM

#

yeah

fading dirge Jan 31, 2026, 5:43 PM

#

mb, didnt read post properly

sullen acorn Jan 31, 2026, 5:43 PM

#

im trying to make the cursed technique "ratio" from jjk

#

if you know what that does

fading dirge Jan 31, 2026, 5:43 PM

#

the one wher u hit at 3/7 of something, right?

sullen acorn Jan 31, 2026, 5:44 PM

#

yeah

#

so the direction is kinda needed cuz your hitting across a imaginary line

fading dirge Jan 31, 2026, 5:44 PM

#

not sure you even need to detect direction of swipe for that, just detect if the hit is near the part of length

sullen acorn Jan 31, 2026, 5:44 PM

#

i want the line to be diffrent each time

fading dirge Jan 31, 2026, 5:45 PM

#

it should be easy to just check the length of object for that

sullen acorn Jan 31, 2026, 5:45 PM

#

its for a player and idk how to do that ):

fading dirge Jan 31, 2026, 5:46 PM

#

sullen acorn its for a player and idk how to do that ):

if the line is always vertical you just do {player head} - {the y level player is on, you can use "player get is grounded" chip for that}

#

that'll give you players height

#

then you just check if hit was at a specific distance relative to that height (so like the y level of collision should be (3*heigt)/7 if i remember the ability correctly)

sullen acorn Jan 31, 2026, 5:48 PM

#

yeah...

#

would you be ever so kind and try make a image of what that would like

#

sorry if its too much trouble ):

fading dirge Jan 31, 2026, 5:54 PM

#

sullen acorn would you be ever so kind and try make a image of what that would like

when you spawn a player (make sure to run only for local player) > float variable (name it "player height)

to that variable you connect:
player get head position > vector3 split (use y output for next steps) > subtract (1st input)
local player > get position (will get position at players feet) > vector3 split (use y output for next step) > subtract (the earlier one, 2nd input)
connect the output of subtract to the variable

#

that'll give you the players height

#

you can use that for other stuff

sullen acorn Jan 31, 2026, 5:56 PM

#

#

i have this

fading dirge Jan 31, 2026, 5:57 PM

#

yep

#

now you just connect that variable to whatever you use to spawn player into the game

#

or you can connect it to "event receiver" (set event to Update30Hz)

#

that will check the height a lot of times per second keeping the height always somewhat accurate

sullen acorn Jan 31, 2026, 5:58 PM

#

how to i now get the 3 / 7 part

fading dirge Jan 31, 2026, 5:58 PM

#

sullen acorn how to i now get the 3 / 7 part

to get y level of 3/7 you just multiply that height by 3 and divide result by 7

sullen acorn Jan 31, 2026, 5:59 PM

#

epic

fading dirge Jan 31, 2026, 5:59 PM

#

or just multiply by 0,4285714285714 (aprox. 3/7th)

sullen acorn Jan 31, 2026, 5:59 PM

#

crazy maths

fading dirge Jan 31, 2026, 5:59 PM

#

calc

sullen acorn Jan 31, 2026, 6:00 PM

#

ah

#

so thats epic i can detect if someone hits you in the 3 / 7 of your height

fading dirge Jan 31, 2026, 6:00 PM

#

well you just have the y level of that 3/7th of height

sullen acorn Jan 31, 2026, 6:01 PM

#

oh

fading dirge Jan 31, 2026, 6:01 PM

#

to detect a hit, you just check if hit positions y level is close to that

sullen acorn Jan 31, 2026, 6:01 PM

#

yeah

fading dirge Jan 31, 2026, 6:01 PM

#

make sure to give some wiggle room for that cause its basically impossible to hit precisely at 3/7s even with hints

sullen acorn Jan 31, 2026, 6:02 PM

#

in the show nanami's ratio isnt just from head to toe

#

it can be diagonal like this also

fading dirge Jan 31, 2026, 6:03 PM

#

well, you could make it work on enemy's limbs but thats more difficult to implement (the hit part at least)

sullen acorn Jan 31, 2026, 6:03 PM

#

yeah i dont really want to do that.

fading dirge Jan 31, 2026, 6:04 PM

#

well, if you get players height only once, you could use that value for any rotation of player

#

but only situations when players are rotated diagonaly are when they're seated (f.e. when grabbed by other abilities)

sullen acorn Jan 31, 2026, 6:04 PM

#

hmm

#

is there a way to randomize where the 3 / 7 ratio is?

fading dirge Jan 31, 2026, 6:05 PM

#

if you're adding monsters, you just get the values once manually and clamp the ratio to stuff you want it to work

fading dirge Jan 31, 2026, 6:05 PM

#

sullen acorn is there a way to randomize where the 3 / 7 ratio is?

wdym by randomize

sullen acorn Jan 31, 2026, 6:05 PM

#

like its more near the top or more near the bottom

#

idk how to explain stuff

fading dirge Jan 31, 2026, 6:06 PM

#

well, you could just subtract 3/7 from the height to get 4/7 (aka 3/7 from top)

#

and you can do method i walked about earlier (multiply and divide) for bottom 3/7

sullen acorn Jan 31, 2026, 6:07 PM

#

hmm

#

thats worth a shot

fading dirge Jan 31, 2026, 6:07 PM

#

to randomize, you take two values, plug it into if value and then you just randomize the bool of that if value

sullen acorn Jan 31, 2026, 6:08 PM

#

and what would that look like...

fading dirge Jan 31, 2026, 6:09 PM

#

to randomize bool you just use random int (1st input is 0, 1nd input is 1) and check if that int is equal to 1

#

sullen acorn Jan 31, 2026, 6:10 PM

#

cool

#

what values do i put into the if value

fading dirge Jan 31, 2026, 6:10 PM

#

sullen acorn what values do i put into the if value

the 3/7 into top and height-3/7 into bottom

#

and connect red from "equals" to the red intput of if value

sullen acorn Jan 31, 2026, 6:12 PM

#

#

i have this

#

#

here is closer

fading dirge Jan 31, 2026, 6:12 PM

#

#

then to get y level of the required height, you take that value and add it to y level of local player

#

#

this

#

then, when you hit someone, check from that someones perspective (aka they have to be the local player in your calculations, basically same as when you check damage stuff in almost all pvp systems) you just check if collision hit positions y level is same as that

this is making my brain hurt

would you be oh so epic and amazing to build this in my room for me before i explode.

nope

would it possible for you to build this in your room and send a pic so i can see where ive gone wrong because im kinda stuck.

#

are you fine with that?

also, you probably dont have any deadline so dont stress it too much

its just this i havent done much

#

but oh well ill go over the guide

fading dirge Jan 31, 2026, 6:27 PM

#

tbh, it is just math and some small tricks

fading dirge Jan 31, 2026, 6:27 PM

#

sullen acorn but oh well ill go over the guide

it goes over very basic stuff

#

cv2 is just programming so you can use tricks from regular programming

sorry

#

wasnt trying to

sullen acorn Jan 31, 2026, 6:35 PM

#

its ok

#

final question

#

how would i turn the 3 / 7 into a vector3 position

fading dirge Feb 1, 2026, 12:04 PM

#

sullen acorn how would i turn the 3 / 7 into a vector3 position

u dont really need to check exact position, u just gotta compare that 3/7 to y level oof hit position
