How do I make a filled block circle?

[RDJpower]

This is an example of what I want to achieve:

How do I make a function that would automatically generate that, and have it centered at a given position?

[LegendPX_Taken (Math)]

are they made of frame?This text will be blurred

[RDJpower]

they are made of parts. not frames.

For the square grid of parts where the circle is, check the distance from center of the part to the center of the circle. If it’s less than the radius, make it “filled”.

-- Define variables
local model = script.Parent -- The model this script is placed in
local radius = 2 -- Replace with your desired radius
local offsetFromCenter = Vector3.new(0, 0, 0) -- Replace with the offset relative to the model's center

-- Calculate the center of the model
local function getModelCenter(model)
	local totalPos = Vector3.new(0, 0, 0)
	local count = 0

	for _, part in pairs(model:GetChildren()) do
		if part:IsA("BasePart") then
			totalPos = totalPos + part.Position
			count = count + 1
		end
	end

	if count > 0 then
		return totalPos / count
	else
		return model.PrimaryPart and model.PrimaryPart.Position or Vector3.new(0, 0, 0)
	end
end

-- Function to light up parts within radius
local function lightUpPartsWithinRadius()
	local center = getModelCenter(model)
	local targetPosition = center + offsetFromCenter

	for _, part in pairs(model:GetChildren()) do
		if part:IsA("BasePart") then
			local distance = (part.Position - targetPosition).magnitude
			if distance <= radius then
				-- Change part properties to make it appear lit up
				part.BrickColor = BrickColor.new("Bright red") -- Example: Change color to red
				part.Material = Enum.Material.Neon -- Example: Change material to neon
			else
				-- Optionally, reset properties for parts outside the radius
				part.BrickColor = BrickColor.new("Bright blue") -- Example: Change color back
				part.Material = Enum.Material.SmoothPlastic -- Example: Change material back
			end
		end
	end
end

-- Call the function to light up parts
lightUpPartsWithinRadius()

That’s not what I want to make. I want to make block parts that create a circle, that center at a given position, with x size.

[LegendPX_Taken (Math)]

-- Settings
local center = Vector3.new(10, 20, 0) -- Center of the circle
local radius = 15 -- Radius of the circle
local partSize = Vector3.new(4, 1, 4) -- Size of each part

-- Create a function to make a part
local function createPart(position)
	local part = Instance.new("Part")
	part.Size = partSize
	part.Position = position
	part.Anchored = true
	part.Parent = workspace
end

-- Determine the number of parts per row
local numPartsPerRow = math.ceil(2 * radius / partSize.X)

-- Create parts in a filled circle
for x = -numPartsPerRow, numPartsPerRow do
	for z = -numPartsPerRow, numPartsPerRow do
		-- Calculate the actual position
		local posX = center.X + x * partSize.X
		local posZ = center.Z + z * partSize.Z

		-- Check if the position is within the circle
		local distance = math.sqrt((posX - center.X)^2 + (posZ - center.Z)^2)
		if distance <= radius then
			local position = Vector3.new(posX, center.Y, posZ)
			createPart(position)
		end
	end
end
