Model not being moved and tweening not working

Help and Feedback Scripting Support

  1. What do you want to achieve? I am making a tower defense game and currently doing the enemy system

  2. What is the issue? Script 1: It doesnt move the enemy. Script 2: Tweening doesnt move it on all the positions only on the first one.

Script 1

function spawnEnemy(enemyType)
	if game:GetService('ReplicatedStorage'):FindFirstChild('Enemies'):FindFirstChild(enemyType) then
		local enemy = game:GetService('ReplicatedStorage'):FindFirstChild('Enemies'):FindFirstChild(enemyType):Clone()
		enemy.Parent = workspace.Map.Enemies
		enemy:SetPrimaryPartCFrame(workspace.Map.Markers.start.CFrame)
	end
end

function run(code)
	for line in code:gmatch("([^\n]*)\n?") do
		local args = split(line)

		if args[1] == 'wait' then
			wait(args[2])
		elseif args[1] == 'spawn' then	
			spawnEnemy(args[2])
		end
	end
end

function split(line)
	local args = {}
	for word in string.gmatch(line,[[([^(),]+)]]) do
		table.insert(args,#args+1,word)
	end

	return args
end

function getSpawnOrder(wave)
	wave = tostring(wave)
	
	local orderscriptUrl = 'http://raw.githubusercontent.com/PatriikPlays/scpTowerDefence/main/spawnOrder/waves/'..wave..'/order.oscript'
	local orderscriptFile = game:GetService('HttpService'):GetAsync(orderscriptUrl)
	return orderscriptFile
end

run(getSpawnOrder(1))

Script 2

local tweenService = game:GetService('TweenService')
local cf = nil
local ammountOfPositions = 0

for i,v in ipairs(workspace.Map.Markers.Positions:GetChildren()) do
	if v:IsA('BasePart') then
		ammountOfPositions = ammountOfPositions + 1
	end
end

local info = TweenInfo.new(
	10/script.Parent.Speed.Value,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.In,
	0,
	false,
	0
)

function tweenModel(model,CF)
	local CFrameValue = Instance.new("CFrameValue")
	CFrameValue.Value = model:GetPrimaryPartCFrame()

	CFrameValue:GetPropertyChangedSignal("Value"):connect(function()
		model:SetPrimaryPartCFrame(CFrameValue.Value)
	end)

	local tween = tweenService:Create(CFrameValue, info, {Value = CF})
	tween:Play()

	tween.Completed:connect(function()
		CFrameValue:Destroy()
	end)
end
cf = script.Parent:GetPrimaryPartCFrame() + Vector3.new(0,100,0)

print(ammountOfPositions)
for i=1,ammountOfPositions do
	tweenModel(script.Parent,workspace.Map.Markers.Positions:FindFirstChild('position'..i).CFrame)
end
