How would I spawn parts on a part?

Ok just give me 1 hour to do it

This should work!

local yCoordinate = 5 --from where it spawns
while true do
	-- sphere equation: x^2 + y^2 + z^2 = r^2
	local radius = script.Parent.Size.X/2   -- radius is half of any size coordinate...you can do Y or Z if you wish
	local part = Instance.new("Part",workspace)
	--setting x^2 + z^2 to equal this
	local circleRadiusSquared = math.pow(radius,2) - math.pow(yCoordinate,2)
	local longSide
	local xCoordinate, zCoordinate
	if(part.Size.X>=part.Size.Z) then
		local distanceFromSphere = part.Size.X/2
		local xMax = math.sqrt(circleRadiusSquared)
		local x = math.random(-1*xMax+distanceFromSphere,xMax-distanceFromSphere)
		--now we do z
		local parabola = math.pow(radius,2)-math.pow(yCoordinate,2)-math.pow(x,2)
		distanceFromSphere = part.Size.Z/2
		local zMax = math.sqrt(parabola)
		local z = math.random(-1*zMax+distanceFromSphere,zMax-distanceFromSphere)
		xCoordinate = x
		zCoordinate = z
	else
		local distanceFromSphere = part.Size.Z/2
		local zMax = math.sqrt(circleRadiusSquared)
		local z = math.random(-1*zMax+distanceFromSphere,zMax-distanceFromSphere)
		local parabola = math.pow(radius,2)-math.pow(yCoordinate,2)-math.pow(z,2)
		--now we do x
		distanceFromSphere = part.Size.X/2
		local xMax = math.sqrt(parabola)
		local x = math.random(-1*xMax+distanceFromSphere,xMax-distanceFromSphere)
		xCoordinate = x
		zCoordinate = z
	end
	part.Position = Vector3.new(xCoordinate,yCoordinate,zCoordinate)
	task.wait(3)
end

Don’t know if I did this right but it doesn’t do anything when it put it in a sphere.

#24

This assumes that the sphere is positioned at (0,0,0)
Is your sphere positioned at that? Otherwise, just simply do

part.Position = Vector3.new(xCoordinate,yCoordinate,zCoordinate) + sphere.Position
#25

yup it works. even on cylinders. thanks
