need some help with my code

[ornate river]

trying to make the parts (literally called "part") rotate in sync around the "centre part without it disrupting their individual rotation around the centre. Basically making a separate rotation for the part as a whole on top of the parts individual rotation.

[open vault]

This can easily be achieved my manipulating the pivot of the part

[ornate river]

the central part?

[ornate river]

the code creates seperate parts and has them orbit around a centre, they arent under one part

[open vault]

why not just set everyones pivot the the center OR make a model and set this pivot to center

[ornate river]

if i set all the parts pivot to the centre, the radius no longer becomes dynamic but ill try the model one

[open vault]

It would look something like this

Make sure the center part is the PrimaryPart of the model

[ornate river]

when i try to rotate the parts they are put back into their original position because of how their rotation is calculated

[open vault]

yo

Lets forget math and scripting

What do you want to achieve

[ornate river]

basically a second rotation

a global and independant rotation for the parts

[open vault]

Why is the Model one not working

[ornate river]

when you rotate the parts in the model, it moves them but the calculation for rotation wouldnt change so it just puts them back to where they would be

[open vault]

what the hell are you calculating

[ornate river]

local phase = math.random() * 2 * math.pi
-- Animation variables
local angle = 0 -- Current angle in radians
local Time = 0
-- Start animation loop using Heartbeat
local function Destroy()
while part.Transparency < 1 do
part.Transparency += 0.01
task.wait(0.001)
end
part:Destroy()
end

        task.spawn(function()
            while part and part.Parent do
                local dt = RunService.Heartbeat:Wait()
                
                -- Update angle (convert degrees/sec to radians/sec)
                angle += math.rad(rotationSpeed) * dt
                

                
                Time += dt
                -- Calculate new position
                local x = math.cos(angle) * radius
                local z = math.sin(angle) * radius
                local y = origin.Y + math.sin(tick() * bobFrequency + phase) * bobAmplitude + (Time*60)
                
            
                
                
                radius = (math.sin(Time * 0.25 * math.pi * 2 ) * 7) + 7 -- Distance from the center
                
                -- Apply position
                part.Position = Vector3.new(origin.X + x, y, origin.Z + z)
            end
        end)
        
        
        local targetSize = Vector3.new(73.489, 17.936, 73.489) * 1.25
        local SizeTweenInfo = TweenInfo.new(1.25,Enum.EasingStyle.Quad,Enum.EasingDirection.InOut)
        local sizeTween = TweenService:Create(part,SizeTweenInfo,{Size = targetSize})
        sizeTween:Play()

it basically is tracking the co-ordinates around a circle using radians to find where it would be

[open vault]

[ornate river]

am i cooked?

[open vault]

aint no way anyone able to read that

kinda

no ones gonna look through that script cause its so ahh to read

but we can find a diffrent solution which is also more readable and maybe easier for you

I just dont understand what you are trying to do

[ornate river]

i was thinking that if i can change the starting orientation, that it would have the same effect

[hot osprey]

** You are now Level 2! **

[ornate river]

since its all rotating at the same rate rn, if i change the point at which it starts to go out, then it might work

[open vault]

this is how I understood it you want 2 rotation thingies

[ornate river]

sort of ye

[open vault]

but a model would legit do that or not

[ornate river]

na

[open vault]

I dont get it

I would do this with PivotOffset tho

and not with tweening

[ornate river]

the tweening is only for the size

[open vault]

or like tween but

bro

I dont even understand where you would use that

like watafak

are you even doing

[ornate river]

basically a tornado

[open vault]

USE A FUCKING MODEL AND ROTATE THE PRIMARY PARTTTTTTT

why wouldnt that work

[ornate river]

i cant adjust the radius if i use a model

[open vault]

then use pivot there you can

https://create.roblox.com/docs/reference/engine/classes/BasePart#PivotOffset

This is the simpliest way of fixing ur problem

[ornate river]

hang on im onto something

[open vault]

you could do that cause PrimaryPart.Position - OtherPart.Position = Radius

[open vault]

alr

[ornate river]

omg it worked lol

thats so dumb

local x = math.cos(angle+xOffset) * radius
xOffset += 0.05

that was literally all i had to do

[open vault]

fuck math

dont send me that

[ornate river]

ikr

[open vault]

I dont want anything todo with that

[ornate river]

dude i spent 2 hours learning radians to jsut add an offset

im so done

[open vault]

I learnt 3h yesterday about Type Checker

[ornate river]

the hell is a typechecker

[open vault]

--!strict

--[[
======================
==== END USER API ====

export type API = {
    DEBUG: boolean,
    _VERSION: string
}

local _API : API = {
    DEBUG = false,
    _VERSION = "0.1"
}




local API = setmetatable({}, {
    __index = _API,
    __newindex = function(_, input, newvalue)
        
        if input:match("^_") then
            error(`\n{input} is read-only`)
            return 
        end
        
        if typeof(rawget((_API :: any), input)) ~= typeof(newvalue) then 
            error(`\n{input} assigned wrong type: \nexpected: {typeof(rawget((_API :: any), input))}, \ngot: {typeof(newvalue)}`)
            return 
        end

        (_API :: any)[input] = newvalue
    end
})

return API

just to create this

[ornate river]

mate im lost on the first line

[open vault]

--!strict activates the like strict mode for type checker

[ornate river]

is this just to check for like data type values

[open vault]

_API has the type API and DEBUG is supposed to be a boolean so it underlines it orange cause its a number that there is something wrong yk

[ornate river]

oh i get it

so it just stops people putting the wrong type of data like a integer for a boolean value

[open vault]

basicly

also if you use auto completion from a custom module itll show you what type it needs

[ornate river]

might learn that if i have the time

[open vault]

ye its pretty intresting

but not really needed if you have basic stuff

if you dont use --!strict its just not gonna show you that its the wrong type

[ornate river]

i hate it when code does stuff like that

cant it just realise that i want it to show me

[open vault]

Lua has no constants thats why this exists probably

local number : number = 3

number = "x"

its not wrong but if you expect the number to be a number and like make math with it even tho its a string its gonna crash and thats like the main reason to learn it

heres an example of the auto complete btw

[ornate river]

ive done python and is it not the same in lua where you can just go int(variable) and make sure its an integer

[open vault]

you can do tonumber()

but maybe thats just luau idk

[ornate river]

if that works then why cant you just do that instead of learning the type check

[hot osprey]

** You are now Level 3! **

[ornate river]

this bot i swear

[open vault]

that was an example if you expect a ValueBase and you want to change the Value but its not a ValueBase thats gonna also crash

local Bool : ValueBase = 3
Bool.Value = true --error

the strict type checker is gonna tell you "yo thats the wrong type here"

[ornate river]

so it will just do a warning and then move on instead of an outright crash

[open vault]

no itll just show you

[ornate river]

so it will still crash

[open vault]

orange thingy

[ornate river]

oh

[open vault]

yes it will crash

[ornate river]

so you dont even have to run it

[open vault]

yes

[ornate river]

and itll detect

[open vault]

ye

[ornate river]

ok thats cool

[open vault]

if you want a value to be a changeable type you can give it local newVar : any = 3

[ornate river]

so then you can make that into a string later

[open vault]

yes

but that breaks the use of strict

[ornate river]

where could you use this

[open vault]

local API = setmetatable({}, {
    __index = _API,
    __newindex = function(_, input, newvalue)
        
        if input:match("^_") then
            error(`\n{input} is read-only`)
            return 
        end
        
        if typeof(rawget((_API :: any), input)) ~= typeof(newvalue) then 
            error(`\n{input} assigned wrong type: \nexpected: {typeof(rawget((_API :: any), input))}, \ngot: {typeof(newvalue)}`)
            return 
        end

        (_API :: any)[input] = newvalue
    end
})

return API

Here

I know 100% that _API is the right type thats why im forcing it to be any

[ornate river]

but like what is its use in like a game scipt

where can you apply it

[open vault]

wdym

[ornate river]

if i wanted to use a Instance thats to like make a new part so i can spawn new things into the game. so i can use that to make new things. what exactly can you do with checking the data type of something.

surely you should already know what type it is

or am i just being thick

[open vault]

local function resizePart(part : BasePart) --makes sure its a BasePart
    part.Size = Vector3.new(5,5,5)
end

resizePart(game.Workspace.Part)

do you mean something like this

[ornate river]

ye

surely you already know what you are putting into it

[open vault]

o wait

you wanted to know wehn to use any

[ornate river]

no i mean when to you the checking this as a whole

like why would i need to check it if i know what im putting in

[open vault]

Lets say you have 1000 lines of code and you want to call a function but you forgot if it needs a string or a number with type checker youll instantly know what you need cause it gets orange

[ornate river]

so it basically is a quick way to check variable types

[open vault]

yes

it doesnt really have a use case in the game mechanics but for yourself

[ornate river]

thats pretty cool

i wont use it because my code rn is like 200 lines max

but it sounds helpful

[open vault]

ye

I also just started using it after like 5 years with luau

[ornate river]

i got like 4 months on it and i look at the pro scripting channel and it looks like ancient aztec

i swear i saw someone summoning a demon in that code

anyway thanks for the help

and telling me about the type check

[open vault]

FR THO THESE PEOPLE ARE CRAZY
