summer walrus how do u send it like that

add 3 ` before start and after end of code like this

#

and add do it like 3 `lua
next line code

#

to add code stuff

summer walrus Jan 22, 2024, 3:37 PM

''' aa ''

does this work btw

#

i didnt look at entire code but it might fix

summer walrus Jan 22, 2024, 3:38 PM

#

the loop's purpose was to make a smooth turn on the body velocity

#

depending on the players look direction

#

it does it one time

#

but then gives me a error that body velocity doesnt exist

cedar dock Jan 22, 2024, 3:38 PM

#

OH

#

the issue is

#

you are using a infinite loop

summer walrus Jan 22, 2024, 3:39 PM

#

cedar dock you are using a infinite loop

o

cedar dock Jan 22, 2024, 3:39 PM

#

and then doing code after that

#

debounce wont ever be false

#

as the code in the while loop runs forever

summer walrus Jan 22, 2024, 3:39 PM

#

ohhh

#

waitt that makes sense

cedar dock Jan 22, 2024, 3:39 PM

#

  while true do
            wait()
            bv.MaxForce = Vector3.new(math.huge,0,math.huge)
            bv.P = 50000
            bv.Velocity = knockback
            bv.Parent = humRP
            game.Debris:AddItem(bv,0.8)
        end```

#

this runs forever

#

never stops

#

thats why

#

nothing after it ever runs

summer walrus Jan 22, 2024, 3:40 PM

#

so i gotta break it when char:FindFirstChild("bv") is false

#

dwag that makes sense

#

let me try

cedar dock Jan 22, 2024, 3:40 PM

#

you can do it like

#

that

#

break it when its false

#

while char:FindFirstChild("bv") do
..........
end

cedar dock Jan 22, 2024, 3:41 PM

#

cedar dock while char:FindFirstChild("bv") do .......... end

i think this might work aswel

summer walrus Jan 22, 2024, 3:41 PM

#

lemme try

#

loading rn

#

if it works ima be happy af

summer walrus Jan 22, 2024, 3:44 PM

#

cedar dock while char:FindFirstChild("bv") do .......... end

this prob wont work cz when i create the bc instance its not in the char yet

#

ill try while bv do

cedar dock Jan 22, 2024, 3:44 PM

#

summer walrus this prob wont work cz when i create the bc instance its not in the char yet

i mean

#

i thought it is

summer walrus Jan 22, 2024, 3:44 PM

#

the bv gets into char in the loop

cedar dock Jan 22, 2024, 3:44 PM

#

summer walrus so i gotta break it when char:FindFirstChild("bv") is false

as you said this

summer walrus Jan 22, 2024, 3:44 PM

#

yea lmao

#

i forgor

#

same thing as with the while tru

misty gardenBOT Jan 22, 2024, 3:45 PM

#

studio ** You are now Level 2! ** studio

summer walrus Jan 22, 2024, 3:45 PM

#

true

cedar dock Jan 22, 2024, 3:45 PM

#

cedar dock ```lua while true do wait() bv.MaxForce = Vector3.new(...

it gets into hrp not char right

#

then wont it be

#

hrp:FindFirstChild("bv")

#

not char

#

i mean

#

it can just go deeper

#

to hrp

#

but hrp might be better for performance

summer walrus Jan 22, 2024, 3:45 PM

#

yea i use hrp

#

same thing as with the while true loop bruu

cedar dock Jan 22, 2024, 3:46 PM

#

try tho

cedar dock Jan 22, 2024, 3:46 PM

#

summer walrus same thing as with the while true loop bruu

send the while loop code rq

summer walrus Jan 22, 2024, 3:46 PM

#

wait

#

does game.Debris:Additem delete

#

the bv?

cedar dock Jan 22, 2024, 3:46 PM

#

whats bv anyway

summer walrus Jan 22, 2024, 3:46 PM

#

body velocity

#

its a dash script which turns with the players camera

cedar dock Jan 22, 2024, 3:46 PM

#

whats the error

cedar dock Jan 22, 2024, 3:47 PM

#

summer walrus the bv?

oh

#

that might be the problem

#

it deletes bv

#

then you try to reparent it

#

if you delete something then try to reparent it

summer walrus Jan 22, 2024, 3:47 PM

#

OH

cedar dock Jan 22, 2024, 3:47 PM

#

it sends that error

#

i forgot that lol

#

i read that somewhere in dev forum

#

😅

summer walrus Jan 22, 2024, 3:48 PM

#

WAIT RIGHT

#

DUDE UR SMART AF

#

1 SEC

#

ILL BREAK IT WHEN BV FALSE

cedar dock Jan 22, 2024, 3:48 PM

#

do that before reparenting

#

else

#

its gonna

#

send that error

summer walrus Jan 22, 2024, 3:49 PM

#

do i use findfirstchild?

cedar dock Jan 22, 2024, 3:49 PM

#

for what

summer walrus Jan 22, 2024, 3:49 PM

#

cz if i use it before the parent its not gonna be in the player

#

to break it

cedar dock Jan 22, 2024, 3:49 PM

#

oh also

#

dont just use wait()

#

add a value

#

else its gonna be different

summer walrus Jan 22, 2024, 3:49 PM

#

o

cedar dock Jan 22, 2024, 3:49 PM

#

like very low difference

#

but its gonna be difference

#

for some machines

summer walrus Jan 22, 2024, 3:50 PM

#

ill make it 0.001 then

cedar dock Jan 22, 2024, 3:50 PM

#

its gonna be like of 0.01 or sum

#

but yeah

#

difference

summer walrus Jan 22, 2024, 3:50 PM

#

0.01 also works

#

wait

#

how do i check if the bv exists

#

i do if bv then?

cedar dock Jan 22, 2024, 3:50 PM

#

wdym

summer walrus Jan 22, 2024, 3:50 PM

#

like how to check if its destroyed

cedar dock Jan 22, 2024, 3:51 PM

#

i never did that so idk if if bv will work

#

you can make a variable tho

#

like

#

outside while loop make

local bvdestroyed = false```

#

turn it on after the adddebris

#

and check

#

that is it on

#

or off

summer walrus Jan 22, 2024, 3:52 PM

#

debris doesn't make it wait

#

its gonna trigger it after 0.01

#

seconds

cedar dock Jan 22, 2024, 3:53 PM

#

0.8 is like a very small number anyway

#

idk tho

summer walrus Jan 22, 2024, 3:53 PM

#

lemme try sum

cedar dock Jan 22, 2024, 3:53 PM

#

@summer walrus wait

#

you can instead of making varibale do like

summer walrus Jan 22, 2024, 3:54 PM

#

WAIT

cedar dock Jan 22, 2024, 3:54 PM

#

if bv.Parent == nil

summer walrus Jan 22, 2024, 3:54 PM

#

o

cedar dock Jan 22, 2024, 3:54 PM

#

cedar dock if bv.Parent == nil

that checks

#

if its

#

parent is nil

#

and if thats nil

#

you either didnt assign a parent

#

or its destroyed

summer walrus Jan 22, 2024, 3:54 PM

#

heres the error btw

cedar dock Jan 22, 2024, 3:54 PM

#

wait no you declare its parent in the loop anyway

summer walrus Jan 22, 2024, 3:54 PM

#

cedar dock Jan 22, 2024, 3:54 PM

#

summer walrus

yep

#

def

#

its because

#

its deleted

#

cuz its parent is null

summer walrus Jan 22, 2024, 3:55 PM

#

oh

cedar dock Jan 22, 2024, 3:55 PM

#

aka bv is destroyed so you cant

#

reparent it

#

cuz it doesnt exist

#

:/

summer walrus Jan 22, 2024, 3:56 PM

#

is destroyed/deleted, It will always return nil. So just check if it is nil within an if statement.

#

checked on forum

cedar dock Jan 22, 2024, 3:56 PM

#

yeah didnt i say that

#

:/

summer walrus Jan 22, 2024, 3:56 PM

#

so if i do "if bv = nil" then break?

cedar dock Jan 22, 2024, 3:56 PM

#

Now i have become forum , Crator of worlds

summer walrus Jan 22, 2024, 3:56 PM

#

itll work?

cedar dock Jan 22, 2024, 3:56 PM

#

no

#

if bv.parent = nil

#

wait

#

will bv be nil

#

or parent be nil

#

actually bv will be nil

summer walrus Jan 22, 2024, 3:56 PM

#

bv

cedar dock Jan 22, 2024, 3:56 PM

#

i think

#

you can try

#

that will work

#

cuz bv will be nil too

#

cant you just do

while bv ~= nil do
            wait()
            bv.MaxForce = Vector3.new(math.huge,0,math.huge)
            bv.P = 50000
            bv.Velocity = knockback
            bv.Parent = humRP
            game.Debris:AddItem(bv,0.8)
        end```

summer walrus Jan 22, 2024, 3:57 PM

#

o

cedar dock Jan 22, 2024, 3:57 PM

#

that looks better

summer walrus Jan 22, 2024, 3:57 PM

#

yea

cedar dock Jan 22, 2024, 3:57 PM

#

and does the same thing

#

@summer walrus does it work

summer walrus Jan 22, 2024, 3:59 PM

#

i was rewriting

#

how do u do this script thing i still dont get it

#

''' . '''

cedar dock Jan 22, 2024, 4:00 PM

summer walrus it gives the same error

send error

summer walrus Jan 22, 2024, 4:02 PM

#

ohhh

#

it only sets parts to nil

#

for instances its different

cedar dock Jan 22, 2024, 4:02 PM

try doing it and removing game.Debris:AddItem(bv,0.8) once

cedar dock Jan 22, 2024, 4:02 PM

#

summer walrus for instances its different

😭

#

try

#

bv.parent

#

actually no

#

its nil at start too

#

isnt it

summer walrus Jan 22, 2024, 4:03 PM

#

Currently, the only way to absolutely check if a part is destroyed is by trying to access one of these locked-down properties in a pcall and see what the error is. This is not sufficient

#

i dont get it

#

lmao

cedar dock Jan 22, 2024, 4:04 PM

#

summer walrus Currently, the only way to absolutely check if a part is destroyed is by trying ...

do print(bv.parent, "1") before the while

#

and print(bv.parent, "2") after the while

#

tell me what it prints on both

summer walrus Jan 22, 2024, 4:05 PM

#

k

#

#

@cedar dock

#

cant i

#

parent it befoer

#

wit

#

wait

#

what if i parent it before the while tru

#

and add the debris before aswell

#

OK GOOD THE ERROR IS GONE

#

NOW WHEN ITS FINISHED ITS PARENT IS NIL

#

it says in the print

#

now i can do ```lua
if bv.Parent == nil then
break
end

#

IT WORKS
