How do I make a part that goes from a specific place to me?

I'm trying to make a part that starts at a part and end at me the character this is my script for a beam effect but im looking for a cylinder part

	local character = player.Character
	if character.HumanoidRootPart.Position.Y < 100000 then
		local BP = Instance.new("BodyPosition",character.HumanoidRootPart)
		local Attachment1 = Instance.new('Attachment',character.HumanoidRootPart)
		game.Workspace.Construction.OwnersHome.Transmitter.Beam.Attachment1 = Attachment1
		BP.Position = game.Workspace.Construction.OwnersHome.Transmitter.Position+Vector3.new(0,10,0)
		BP.MaxForce = Vector3.new(10000,10000,10000)
		BP.D = 4150
		game.Workspace.Construction.OwnersHome.Platform.CanCollide = false
		game.Workspace.Construction.OwnersHome.Transmitter.CanCollide = false
		game.Workspace.Construction.OwnersHome.Platform.Touched:Connect(function(hit)
			if hit.Name == "RightFoot" or hit.Name == "LeftFoot" then
				BP:Destroy()
				Attachment1:Destroy()
				game.Workspace.Construction.OwnersHome.Platform.CanCollide = true
				game.Workspace.Construction.OwnersHome.Transmitter.CanCollide = true
			end
		end)
	elseif character.HumanoidRootPart.Position.Y >= 100000 and character.HumanoidRootPart.Position.Y <= 100005 then
		local BP = Instance.new("BodyPosition",character.HumanoidRootPart)
		local DP = Instance.new("Part",workspace.Construction)
		local Attachment1 = Instance.new('Attachment',DP)
		character.HumanoidRootPart.Position = game.Workspace.Construction.OwnersHome.Transmitter.Position
		game.Workspace.Construction.OwnersHome.Transmitter.Beam.Attachment1 = Attachment1
		DP.CanCollide = false
		DP.Transparency = 1
		DP.Anchored = true
		DP.Name = "DestinationPart"
		DP.CFrame = Mouse+Vector3.new(0,-100000,0)
		BP.Position = DP.Position
		BP.D = 4175
		BP.MaxForce = Vector3.new(10000,10000,10000)
		game.Workspace.Construction.OwnersHome.Platform.CanCollide = false
		game.Workspace.Construction.OwnersHome.Transmitter.CanCollide = false
		local function feetOntouch(hit)
			if hit.Name == "Terrain" then
				game.Workspace.Construction.OwnersHome.Platform.CanCollide = true
				game.Workspace.Construction.OwnersHome.Transmitter.CanCollide = true
				DP:Destroy()
				BP:Destroy()
			end
		end
		character.LeftFoot.Touched:Connect(feetOntouch)
		character.RightFoot.Touched:Connect(feetOntouch)
	end

try this

local beam = workspace.Cylinder --name the cylinder Cylinder




script.Parent.Touched:Connect(function(hit)
	local character = hit.Parent
	local humanoid = hit.Parent:FindFirstChild ("Humanoid")
	
	
	if humanoid then
		
		beam.CFrame = CFrame.new(hit.Parent.UpperTorso.Position)--if you are using r6 use Torso and not Upper Torso
		-- you can change UpperTorso to whatever body part you want
		
		wait(1)
	end
	
	wait(1)
end)
