Need help with a sliding puzzle

[severe merlin]

Hello im making a project and one of the puzzles im making is a sliding puzzle however its having a problem that i dont know how to fix basically when i click play it works and all being able to move the pieces but the main problem is that it spawns in a complete different place from where it shows in studio when i click play, and if i move it manually it breaks and it shows it completed and you cant touch anything. Any help? here is the script

and here is the problem of where it spawns

[severe merlin]

i believe it has to be with the vector but i dont really know anyone can help :c?

[errant crown]

Can you post the code as a code block instead of images?

[fallen viper]

send me a code

[severe merlin]

sorry my timezone is different

thats why i replied late

[errant crown]

I dont have a good luau viewer on my phone, so i asked deepseek to just write it in its app code viewer 🫠, but it tought this

U are missing a function in the txt file 🫠

[severe merlin]

huh oh

weird cause roblox studio doesnt show an error in the script

[errant crown]

Do you ever move the puzle model?

The only thing i can think of is that the model pivot point is in the middle of nowhere

At somepoint you use model:moveTo() or model:PivotTo() and that causes unexpect behavoiur

[severe merlin]

oh you mean this?

oh whoops idk why is it at 4,4,1

[errant crown]

Yeah that, try setting the pivot offset to zero and no primary part

Or just using a folder instead of a model

[severe merlin]

aight done let me try moving it

eh the script makes it spawn somewhere else instead of where i put it in studio

[severe merlin]

well idk whats causing this

atp ill just manually change the position from the script myself

[errant crown]

The positioning is relative to the workspace origin rather than the puzzle model due to how the Position property is set and the coordinate system used. Here's why:

1. Absolute Positioning:

   tile.Position = Vector3.new((x - 85) * tileSize, tile.Position.Y, (y + 57) * tileSize)
   

   • This sets the tile's position in world space (workspace coordinates)
   • The calculation doesn't reference puzzleModel's position, making it absolute rather than relative

2. Coordinate System:

   • Roblox parts use workspace coordinates by default when setting .Position
   • To position relative to the model, you'd need to:
     1. Get the model's CFrame (position + orientation)
     2. Convert local positions to world space using modelCFrame * Vector3.new(x, y, z)

3. Offsets Explained:

   • (x - 85) and (y + 57) are hardcoded offsets
   • These likely place the puzzle grid in a specific location in the workspace
   • For a 5x5 grid (gridSize=5), this centers tiles around:
     • X: (3 - 85)*4 = -328 (since middle tile x=3)
     • Z: (3 + 57)*4 = 240

4. Why it works:

   • The tiles are children of puzzleModel, but their positions are set in world space
   • When the model moves, its children move with it (inheriting transform)
   • The initial positions are calculated relative to world origin, not model origin

To make it relative to the model, you'd need to:

1. Add a reference part in the model (e.g., PuzzleOrigin)
2. Modify setTilePosition:

   local origin = puzzleModel.OriginPart.Position
   tile.Position = origin + Vector3.new((x-3)*tileSize, 0, (y-3)*tileSize)
   

   (Where 3 is half of gridSize=5 for centering)

The current approach is simpler but assumes:

• The model starts at a known position
• No rotation is applied to the model
• Tile Y-positions are preserved from their original placement

ai intensifies

I know, i know what the issue is, but too much text to write myself

[errant crown]

Give my fingees a brake, is not easy to write that much text on a phone screen 😭

[south nexus]

wat is the issue?

[errant crown]

He had the coordinates hardcoded

Instead of being relative to the model

I tought his problem was that it was being placed in the wrong hardcoded position

[south nexus]

there are no hardcoded coordinates, which is the problem, close enough i guess, the ai is close enough too

[severe merlin]

so then

[south nexus]

oh nvm there are hardcoded coords, the image and the code are different

[severe merlin]

i can record myself in any case to show what happens when i click play and when i move it manually

[south nexus]

you can't move it though

the ai explained this

[severe merlin]

yeah i know if i move the model manually once i click play it just breaks

[south nexus]

one of the few occasions where it is correct

[severe merlin]

but if i leave it where it is, it spawns somewhere else

so ill just change the position inside the script

in studio it will show somehwere else but in game it will show where i want

[south nexus]

it doesnt matter where you put it in studio ?

[severe merlin]

it does

if i put it where i want it to be then hit play

[south nexus]

what makes you think it does?

[severe merlin]

the puzzle is shown completed

and you cant move anything

[south nexus]

i mean in its current state

[severe merlin]

i just told u

[south nexus]

this would be a different problem to its position

[south nexus]

which the ai also appears to have picked up on

[severe merlin]

it works perfectly if i dont move it

[south nexus]

server script or localscript?

[severe merlin]

local

[south nexus]

thought so, so yea ai not gonna pick up on that unless you know to ask. the parts dont exist yet on the client when this code runs. workspace instance streaming

[severe merlin]

see

if i change it manually from the script it works

if i move it from studio it breaks

honestly i dont mind if it shows somewhere else in studio

[south nexus]

set the model's streamingmode to atomic

[severe merlin]

what does that do

[south nexus]

magic. just do it

persistent would also work

i prefer atomic personally

[severe merlin]

huh WHAT it worked

like i moved it without the script and its there and it works

wow Tysm

[south nexus]

wait for it...

[errant crown]

I just assumed it was a server script 😔

[severe merlin]

wait for what

[south nexus]

unless you already fixed the other 2 problems

[severe merlin]

i did

thats the only thing annoying me

the position between play and studio

[south nexus]

yea that was 2 fold, one was instance streaming the other was hardcoded positions, and then you have clicks not working

[severe merlin]

anyway thank you a lot both of u

** You are now Level 5! **

[errant crown]

Also what does rankers do?

[south nexus]

i rate scripts for skill ranks #📃︱ranking-tickets

[errant crown]

This server is so weird xd

[south nexus]

it helps with the #💵︱hiring channels so you have some idea what people are capable of

[errant crown]

Makes sense, which is the ratio of slop to good work of the submissions?

[south nexus]

as you would expect

there are far more beginners than there are experts.

[errant crown]

Interesting

[errant crown]

How much would you crucify someone for doing that?

In a scale from 1 to 10

[south nexus]

depends on your code, if you want to config that way it's fine. the only sin i see is Stadistics

[errant crown]

Instead of using tables i use folders with objectValues with more folders, and just clone the folder for each object i want to create 😂, just so i can use typeof(sillyFolder) and so that two modules can use objects created by each other with out entering a require() recursion

[south nexus]

skill issue

[errant crown]

I mean, it cant be that much worse for performance, plus you can see objects structures with out neededing to enter any script 🤔

You also get the .changed event and its already replicated to the client so implementing UIs its easier

[south nexus]

don't worry about performance, it doesn't really matter at your stage. just focus on working code

it's a very common misconception started by people who can't handle other people who want to learn how to make games

[errant crown]

Yeah, but im the only one who does things like this? There must be a hyper awfull drawback to that method, the only thing i can think of is exploting, but if someone wanted to reverse engineer your game this barely hurts them 🤔

[distant lance]

** You are now Level 8! **

[south nexus]

no, everyone thinks like that.

it's sad

[errant crown]

Auch

[south nexus]

like this guy for example, who thinks performance and optimization is the be-all end-all of all programming, and decides to insult and mock me because they don't understand why performance should take a back seat to functional code https://discord.com/channels/448986884497211392/1381039650063253676

ironically if they had just set out to write their game instead of hyper-focusing on performance, they would already know how to do what they asked

that's why premature optimization is so bad, it stops you moving forward and learning new stuff

but y'know, to each their own 🤷

[errant crown]

Interesting, well it was nice talking to u 😊 best of lucks

[severe merlin]

@south nexus@errant crownum might need help once more 😭

my puzzle isnt puzzling

this is the updated puzzle, basically what its supposed to do is that once all tiles are in order it activates the proximity prompt of another part but is not doing that for some reason 💔

here is the full picture and completed, the tiles are in order from 1 to 25, 25 being the blank tile one

[severe merlin]

oh i just found out

but now idk how to like rotate it without breaking it

[south nexus]

look into cframe worldspace / objectspace

[errant crown]

two options, you use cframe:PivotTo(Cframe:LookAt(postion_of_your_puzle, vector_where_you_want_it_to_look_at))

or you create a new cframe with newCframe = cframe:lookAt(same as before) and then loop trough all parts of the puzle and do part.cframe = newCframe:toWorldSpace(part.cframe)

vector_where_you_want_it_to_look_at this vector is the orientation you want the puzle to have

so if you want it to look towards the z direction, use vector3.zAxis
