The code is below.

This function instantiates a block that should expand in one direction. It is welded to a ball. The ball works perfectly by the way. It's just welded to the player.

When this part extends, basically the player goes into a frenzy and flings around a bunch. How do I stop this?

local AttackLine = Instance.new("Part", Character)
			AttackLine.CanCollide = false
			AttackLine.Transparency = 0.5
			AttackLine.BrickColor = BrickColor.new("Teal")
			AttackLine.Name = "AttackLine"
			
			AttackLine.Size = Vector3.new(0.2,10,0.2)
			
			
			local weld = Instance.new("Weld", AttackLine)
			weld.Part0 = AttackLine
			AttackLine.CFrame = Character["RightHand"].CFrame
			weld.Part1 = Character["RightHand"]
			weld.C0 = AttackLine.CFrame:inverse()
			weld.C1 = Character["RightHand"].CFrame:inverse()
			
			local originalFrame = AttackLine.CFrame
			
			for i = 0, length, length/10 do
				AttackLine:Resize(Enum.NormalId.Bottom,i*500)--AttackLine.Size:lerp(Vector3.new(0.2,50,0.2), i)
				AttackLine.CanCollide = false
				local weld2 = Instance.new("Weld", AttackLine)
				weld2.Part0 = AttackLine
				AttackLine.CFrame = Character["Chargeball"].CFrame
				weld2.Part1 = Character["Chargeball"]
				weld2.C0 = AttackLine.CFrame:inverse()
				weld2.C1 = Character["Chargeball"].CFrame:inverse()
				wait(0.1)
			end
