Part not damaging humanoid/touching humanoid?

Help and Feedback Scripting Support

#1

I’ve run into a problem where when a part is created it doesn’t damage any players, it doesn’t detect if it is touching them.
It is a script inside a tool. The part moves and all, but it just doesn’t damage or touch.

local tool = script.Parent
local Player = tool.Parent.Parent
local damage = 25
local SpellPower = 10
local Debounce = false
tool.Activated:Connect(function()
    if SpellPower > 1 and Debounce == false then
        local Beam = Instance.new("Part", game.Workspace)
        Beam.CFrame = Player.Character.RightHand.CFrame + Vector3.new(2,2,2)
        Beam.Shape = Enum.PartType.Cylinder
        Beam.TopSurface = Enum.SurfaceType.Smooth
        Beam.BottomSurface = Enum.SurfaceType.Smooth
        Beam.Transparency = 0.2
        Beam.BrickColor = BrickColor.new("Plum")
        local velocity = Instance.new("BodyVelocity")
        velocity.Parent = Beam
        velocity.Velocity = script.Parent.Parent.Head.CFrame.lookVector * 120
	   Beam.Orientation = Vector3.new(0,0,0)
	   wait()
        Beam.Parent = workspace
        Beam:SetNetworkOwner(nil)
        wait()
        Beam.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
			print('Humanoid is taking damage!')	
			local humanoid = hit.Parent:FindFirstChild('Humanoid')	
               humanoid.Health = humanoid.Health - damage
               Beam:Destroy()
			end
		SpellPower = SpellPower - 1
		Debounce = true
		wait(3)
		Debounce = false
		end)
    end
end)

Ok, so sometimes this works now i am seeing, but it also just randomly stops making parts

I meant that it randomly stops making parts, not bc of the cooldown.

local SpellPower = 10

it stops before this reaches 0
