I wanna make the axe go from left to right for an obby, but either my script makes only the primary part moving or its not making anything move. Help

#

i even asked gpt

#

but cant make it work

red belfry Jul 15, 2025, 1:10 PM

#

did you weld the parts to the primarypart

You should probably use aligne position and weld all your model to a handler point

#

or you can use a hinge as a servo

If you realy want to tween your model you will need to use some tricks like Using a Vector3Value and tween it and then with a loop apply the vector3 to your model with :PivoteTo

frank prawn Jul 15, 2025, 2:00 PM

#

umbral mica You should probably use aligne position and weld all your model to a handler poi...

i welded all the parts toegether

#

by making unions

#

and using weld contraints after

#

#

the primary part of the model is "black"

#

and its all the black parts

#

so what youre saying it that i should add a part, weld it to the model

#

handler part

umbral mica Jul 15, 2025, 2:04 PM

#

lika a part to the rotation point

frank prawn Jul 15, 2025, 2:04 PM

#

ok

#

yea

#

and then ?

umbral mica Jul 15, 2025, 2:04 PM

#

then set it to primary part and try to use PivoteTo

frank prawn Jul 15, 2025, 2:04 PM

#

imma try that rn

umbral mica Jul 15, 2025, 2:04 PM

#

or if you want to do something better you use a hinge constraint

frank prawn Jul 15, 2025, 2:04 PM

#

hinge constraint ?

#

dont know what that is

umbral mica Jul 15, 2025, 2:04 PM

#

ye

frank prawn Jul 15, 2025, 2:04 PM

#

sry

umbral mica Jul 15, 2025, 2:04 PM

#

its a instance

frank prawn Jul 15, 2025, 2:04 PM

#

only been scripting for 3 weeks

umbral mica Jul 15, 2025, 2:04 PM

#

like physic instance from roblox

#

its not related with script

frank prawn Jul 15, 2025, 2:05 PM

#

ill make research then

umbral mica Jul 15, 2025, 2:05 PM

#

its just rbx physic system

frank prawn Jul 15, 2025, 2:05 PM

thx

#

this my code and it doesnt work

#

someone help

clever socket Jul 15, 2025, 2:22 PM

#

I dont wanna read allat

#

can you explain your problem again

frank prawn Jul 15, 2025, 2:23 PM

#

look at the video

#

its an axe

#

i want to make it swing from left to right

#

continuelsy

frank prawn Jul 15, 2025, 2:24 PM

#

frank prawn

but instead of that its doing that

clever socket Jul 15, 2025, 2:34 PM

#

like this

#

wrong video

#

like this

#

@frank prawn

frank prawn Jul 15, 2025, 2:37 PM

#

YES

#

exactly

frank prawn Jul 15, 2025, 2:37 PM

#

clever socket like this

gimme

#

pls

#

someone told me to animate it

#

is it the right way of doing it ??

frank prawn Jul 15, 2025, 2:38 PM

#

clever socket like this

idc actually just give me this pls

clever socket Jul 15, 2025, 2:38 PM

#

no

frank prawn Jul 15, 2025, 2:38 PM

#

WHY

clever socket Jul 15, 2025, 2:38 PM

#

your trying todo it right

#

but kinda failing it

clever socket Jul 15, 2025, 2:38 PM

#

frank prawn is it the right way of doing it ??

i was saying no to this

frank prawn Jul 15, 2025, 2:38 PM

Ive been for 2 hours

clever socket Jul 15, 2025, 2:39 PM

local TweenService = game:GetService("TweenService")

local goalCFrame = CFrame.new(currentPosition) * CFrame.Angles(0, 0, math.rad(-50))
local tween = TweenService:Create(proxy, tweenInfo, {Value = goalCFrame})

proxy:GetPropertyChangedSignal("Value"):Connect(function()
    model:SetPrimaryPartCFrame(proxy.Value)
end)

tween:Play()

#

this is my script

#

do you understand it?

frank prawn Jul 15, 2025, 2:39 PM

#

lemme see

#

kinda

#

yea

#

i think

clever socket Jul 15, 2025, 2:40 PM

#

try it out and tell me if it works

#

wait

#

this wont work

frank prawn Jul 15, 2025, 2:41 PM

#

it does work

#

but weird

clever socket Jul 15, 2025, 2:41 PM

local TweenService = game:GetService("TweenService")

#

you can replace this with your original script

frank prawn Jul 15, 2025, 2:41 PM

#

frank prawn Jul 15, 2025, 2:42 PM

#

clever socket you can replace this with your original script

lemme try

clever socket Jul 15, 2025, 2:42 PM

#

oh yea

#

I turned my axe 50 degrees

frank prawn Jul 15, 2025, 2:42 PM

#

so like

#

with that script

#

do i need to weld all the parts toegether

#

or have a "handler part" to make the rotation point ??

#

or do i only need to have the model

clever socket Jul 15, 2025, 2:44 PM

#

local TweenService = game:GetService("TweenService")

local Folder = workspace.SpecialObbies.NoNameObby["Hell (Made by NoName!)(Also please write your obby's name)"]

for i, model in Folder:GetChildren() do
    local currentPosition = model.PrimaryPart.Position
    
    local proxy = Instance.new("CFrameValue")
    proxy.Value = CFrame.new(currentPosition) * CFrame.Angles(0, 0, math.rad(50))

    local tweenInfo = TweenInfo.new(2, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut, -1, true)

    local goalCFrame = CFrame.new(currentPosition) * CFrame.Angles(0, 0, math.rad(-50))
    local tween = TweenService:Create(proxy, tweenInfo, {Value = goalCFrame})

    proxy:GetPropertyChangedSignal("Value"):Connect(function()
        model:SetPrimaryPartCFrame(proxy.Value)
    end)

    tween:Play()
end

#

top is the PrimaryPart and is located at the very top of the axe (turning point)

#

doesnt need to be named top

frank prawn Jul 15, 2025, 2:45 PM

#

okok thx

clever socket Jul 15, 2025, 2:45 PM

#

try this script and tell me if it works

frank prawn Jul 15, 2025, 2:46 PM

#

clever socket try this script and tell me if it works

i love you

#

works

#

perfectly

clever socket Jul 15, 2025, 2:47 PM

#

nice

frank prawn Jul 15, 2025, 2:47 PM

#

just needed to change couple lines

#

add 2 if statements

#

and all good

clever socket Jul 15, 2025, 2:47 PM

#

nice

#

just dont nest the if statements too much alr

frank prawn Jul 15, 2025, 2:47 PM

#

frank prawn add 2 if statements

cause there are a lot of things insside my folder

frank prawn Jul 15, 2025, 2:48 PM

#

clever socket just dont nest the if statements too much alr

why not ?

#

its the best thing in the world

clever socket Jul 15, 2025, 2:48 PM

#

cause it makes it harder for people to read

frank prawn Jul 15, 2025, 2:48 PM

#

oh

#

yea

clever socket Jul 15, 2025, 2:48 PM

#

if true then
     --code
end

if not true then return end
--code

#

you see

#

it does the same thing but is much more readable and you dont nest

frank prawn Jul 15, 2025, 2:49 PM

#

wow

#

crazy

#

a door opened in my head

#

made me learn smtg

clever socket Jul 15, 2025, 2:50 PM

frank prawn Jul 15, 2025, 2:50 PM

frank prawn Jul 15, 2025, 3:13 PM

#

clever socket ```lua if true then --code end if not true then return end --code ```

so like

#

cause i already need to add things to you code

#

i have a question before making the changes

#

i could replace that :

#

#

with that :

#

#

@clever socket

#

????

#

its the if statement that changes

#

btw

clever socket Jul 15, 2025, 3:16 PM

#

model.Name ~= "axe"

frank prawn Jul 15, 2025, 3:17 PM

#

oh

#

yea

woven ventureBOT Jul 15, 2025, 3:17 PM

#

studio ** You are now Level 7! ** studio

frank prawn Jul 15, 2025, 3:17 PM

#

oh

#

but now its not working

clever socket Jul 15, 2025, 3:18 PM

#

you need to continue not return

#

if model.Name ~= "axe" then continue end

frank prawn Jul 15, 2025, 3:19 PM

#

clever socket ```lua if model.Name ~= "axe" then continue end ```

crazy

#

works again

#

th

clever socket Jul 15, 2025, 3:20 PM

#

yk what continue does?

frank prawn Jul 15, 2025, 3:22 PM

#

yea

#

it continues

frank prawn Jul 15, 2025, 3:22 PM

#

clever socket yk what continue does?

continue the code

clever socket Jul 15, 2025, 3:22 PM

#

not really

#

continue is like return but it continues the loop for the rest of the objects in the array

frank prawn Jul 15, 2025, 3:23 PM

#

mmh

#

so

#

ill send the code at then end

clever socket Jul 15, 2025, 3:26 PM

#

alr

frank prawn Jul 15, 2025, 4:03 PM

#

clever socket alr

in the end

#

i havent used ur thing

#

doesnt work

#

too lazy to understand why

#

#

here's my code tho

#

oh wait not finished

#

nvm the pause part is not working

clever socket Jul 15, 2025, 4:14 PM

#

is it working?
