zombie moves only once and doesn't turn and continue?

i'm making a game kinda like tower defense simulator where zombies follow a winding path
however, the zombie only moves once and doesn't turn and continue
here's the script:

for i, v in pairs(game.Workspace.Path:GetDescendants()) do
	if v:IsA("Part") then
		script.Parent.Torso.AlignPosition.Attachment1 = v.ZPos
		repeat wait() until script.Parent.HumanoidRootPart.Position == v.Position
		script.Parent.Torso.AlignOrientation.Attachment1 = v.ZRot
	end
end

Maybe the position isnt exactly the same. Try checking for if the distance is close but not exact. Try using

Distance = (part1.pos - part2.pos).magnitude 

Hope this helps :3
