You can write your topic however you want, but you need to answer these questions:
What do you want to achieve?
I’m interested in the key functions surrounding this specific dance floor in Mad City I’ve never seen anything like it and one would assume it would be a lag machine, it seems to pause when the player leaves the building and resume when the player returns.
What is the issue?
I have replicated this dance floor somewhat, different changing lights and colours patterns was easy but I am neglecting some features for instance it has a sine wave like effect and or some form of tween it also features a galaxy effect to which I have seen and have access to similar particle effects.
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I have figured out the galaxy and particle effect and have applied different colours to my dance floor, as well as different colour patterns I am now looking to optimise it and add some form of flare I am completely inspired by this dance floor now that I’ve seen it and would love to have some light shed on how it works further or parts I may have missed
I have uploaded two videos show-casing the effect I am attempting to achieve and I am mind boggled at the complexity of this small thing, thank you in regards to any responses in advanced.
I’m also very interested in how they achieved the lights
I am neglecting some features for instance it has a sine wave like effect
For the sine wave, I threw something together to attempt to mimic it, and I think this might help with that part you are missing.

I’ll drop a quick explanation here,
I store all the parts in a 2D array, which is like a grid that tells me where each tile is, and importantly, I can index them using X and Y coordinates.
Then, I loop through each part from top left, to bottom right. For every part, I add a sine wave to its Y position, which makes the wave effect. (I am not very knowledgeable about trigonometry or those functions in general, so if I say something wrong, please correct me.). But, I also have to add something to the sine wave in order to make each part offset from the wave. So, I add the X and Y values of each part together to get the part number of the part. (This is sort of hard for me to articulate, as I am not very good at explaining some things, so I’ll just say that the part number is like the number of the part, ex: part 1, part 2, part 3, etc.) Then, I add this value to the sine wave to offset the part from the wave. which makes it further along the wave than the parts before it. (Again, I apologize if this is unclear, I am not the best explainer.)
[EDIT] Whoops, I realized that the dance floor that I made was slower than the video you provided, So, just change the *2 on line 70 to make it faster or slower. Larger numbers are faster.
local wave = math.sin((tick() * 2) + (y + x)) * 0.5 -- Change the tick() * 2 to whatever you want.
I’m not saying this is how Mad City does it, but it could be a possibility.
Video of it in action:
Hope this helps with that aspect of it!
Good luck with your project!
R,G,B,Y are representative of keys for Red, Green, Blue, Yellow and say we wanted to individually have control over what colours to change or nodes to adapt?
Or to even make it somewhat toggle-able?
I have represented this as a node based system let’s say I would like to have functions representing different colour to the parts and have some form of control over the grid and what patterns appear.
Is there a way I could input to the table directly and change these values?
Sorry for going so in-depth but I believe this post will help other users and it’s important for me myself to learn and write correctly now after years of tutorial hell and learning others mistakes and replicating them.
This has greatly helped me with my dance floor project, it’ll probably come up in other projects also, I couldn’t thank you enough regardless!
Here is an example similar to some more effects I’m attempting to achieve. watch all or 0:40 secs to 1 min. It would seem that he is directly pulsing some form of gradient through them and has direct control over each part as he’s not just tweeting them but he is also dynamically controlling an entire line of colours.
If anyone else is interested, there is a model for this in the comments of the video and I’ll be dissecting it and attempting the advanced dance floor, the journey begins.
I’ll try to explain further on my current limited knowledge of sine functions. (If anyone else reads this and knows more than me, or notices something I said wrong, please correct me.)
When using math.sin(x), to create a wave, you input a value that constantly goes up. So I use tick(), which returns the amount of seconds that has passed since January 1, 1970. Which leaves me with math.sin(tick()). This will now return a value between -1 and 1. It will progress between those two values every time tick() changes to make a wave. Now, If I just applied this to the dance floor as is, I would get something like this:
Not as exciting, right?
So, to make the dance floor more like a wave, I offset the tick value by the tile number. This puts each tile further along the wave than the others.
I made a quick graph to show what I mean:
Yes, I would think that using another 2D array, or even the same one for color maps would probably fit this project best.
Yes! We can modify the script to contain a new table for the ColorMap, then initialize the ColorMap along with the grid in the CreateGrid() function, then add another function to apply the ColorMap to the grid like so:
local FloorTiles = {} -- 2D array containing each tile
local ColorMap = {} -- 2D array containing each tile's color.
-- Note: It is probably best to simulate this on the client and dynamically load and unload it
-- to avoid massive server lag.
-- This is server sided just for testing purposes.
local function ApplyColorMap()
for y = 1, #FloorTiles, 1 do
for x = 1, #FloorTiles[y] do
local part = FloorTiles[y][x]
if ColorMap[y][x] then
part.Color = ColorMap[y][x]
end
end
end
end
local function CreateFloor(position:Vector3, tile_size:Vector3, padding:Vector2, grid_size:Vector2)
FloorTiles = {}
local current_position = position
-- Y column
for y = 1, grid_size.X, 1 do
FloorTiles[y] = {}
ColorMap[y] = {}
-- X column
for x = 1, grid_size.Y, 1 do
local new_tile = Instance.new("Part")
new_tile.Position = current_position
new_tile.Size = tile_size
new_tile.Anchored = true
new_tile.CanCollide = false
new_tile.Parent = DanceFloor
-- Setup position for next tile
current_position += Vector3.new(tile_size.X, 0, 0) + Vector3.new(padding.X, 0, 0)
FloorTiles[y][x] = new_tile
ColorMap[y][x] = Color3.new(1, 1, 1) -- Initialize to white, or whatever color you like.
end
-- Reset position X at the end of each X column
local old_z, old_y = current_position.Z, current_position.Y
current_position = Vector3.new(position.X, old_y, old_z)
-- Shift position over for next X column
current_position += Vector3.new(0, 0, tile_size.Z) + Vector3.new(0, 0, padding.Y)
end
ApplyColorMap()
end
So, I also got the model, and dug into it. It appears that the person in the video is using perlin noise to create the waving gradient effects.
I modified the script a little to include a demo of possible perlin noise effects.
local RunService = game:GetService("RunService")
local DanceFloor = game:GetService("Workspace"):WaitForChild("DanceFloor")
local FloorTiles = {} -- 2D array containing each tile
local ColorMap = {} -- 2D array containing each tile's color.
-- What the table looks like:

[1] = {[1] = Part; [2] = Part; [3] = Part; [4] = Part;};
[2] = {[1] = Part; [2] = Part; [3] = Part; [4] = Part;};
[3] = {[1] = Part; [2] = Part; [3] = Part; [4] = Part;};
[4] = {[1] = Part; [2] = Part; [3] = Part; [4] = Part;};
}

This was made using some code from the person in the video.
Also, a few colors might be a little distorted when applying noise. I believe this is because the colors are like (0.94, 0.32, 0.45) and the noise adds it so it goes over 1 on some values. It can probably be fixed by clamping the individual color values to 1 and 0.
To be clear, I am new to perlin noise, so I recommend reading this if you want more info:
