I am trying to that It will only harm the player If they touch a part that Isn't In a humanoid (?)

Hello Developers!

I made this script, this script will force the user to do a drop kick, the problem Is that I want to add a system where If they kick a wall they will get harmed, the problem Is that It will harm the player If they touch a humanoid (Like a NPC or Player) due to the humanoid having parts

Script:

local NPC = script.Parent

if script.Enabled == true then
	local PlayerInventory = game:GetService("Players"):GetPlayerFromCharacter(NPC)
	if PlayerInventory then
		local Tools = PlayerInventory.Backpack:GetChildren()
		for _, Tool in ipairs(Tools) do
			if Tool:IsA("Tool") then
				Tool.Parent = game:GetService("ReplicatedStorage").FolderThatContainsWeapons
			end
		end
		NPC:WaitForChild("Drop Kick").Parent = game:GetService("ReplicatedStorage").FolderThatContainsWeapons
	end
	script.Swoosh:Play()
	local DropKick = NPC.Humanoid:WaitForChild("Animator"):LoadAnimation(script.Kick)
	DropKick:Play()
	NPC.HumanoidRootPart.Anchored = true
	local TweenPropteries = {
		CFrame = NPC.HumanoidRootPart.CFrame + (NPC.HumanoidRootPart.CFrame.LookVector*35)
	}
	local Tweeninfo = TweenInfo.new(
		1,
		Enum.EasingStyle.Cubic,
		Enum.EasingDirection.InOut,
		0,
		false,
		0
	)
	local Tween = game:GetService("TweenService"):Create(NPC.HumanoidRootPart,Tweeninfo,TweenPropteries)
	Tween:Play()
	local Hits = {}
	NPC["Left Leg"].Touched:Connect(function(hit)
		local Character = hit:FindFirstAncestorWhichIsA("Model")
		local Humanoid = Character and Character:FindFirstChildWhichIsA("Humanoid")
		local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if Player then
			local player1 = game.Players:GetPlayerFromCharacter(hit.Parent)
			local player2 = game.Players:GetPlayerFromCharacter(NPC)

			if (player1 ~= nil) and (player2 ~= nil) then
				local humanoid = (player1.Character or player1.CharacterAdded:Wait()):FindFirstChildWhichIsA("Humanoid")

				if (player1.TeamColor ~= player2.TeamColor) then
					if (humanoid ~= nil) and (humanoid.Health >= 0) and not Hits[Character] then
						Hits[Character] = true
						script.Contact:Play()
						Humanoid:TakeDamage(30)
						local RagdollScript = script.Ragdoll:Clone()
						game:GetService("Debris"):AddItem(RagdollScript,2)
						RagdollScript.Parent = humanoid.Parent
						RagdollScript.Enabled = true
						local VectorForce = Instance.new("VectorForce",humanoid.Parent.Torso)
						local Attachment = Instance.new("Attachment",humanoid.Parent.Torso)
						VectorForce.Attachment0 = Attachment
						VectorForce.Force = Vector3.new(0,300,6000)
						VectorForce.ApplyAtCenterOfMass = true
						game:GetService("Debris"):AddItem(VectorForce,0.5)
						game:GetService("Debris"):AddItem(Attachment,0.5)
						wait(1)
						Hits[Character] = false
					end
					if not player1.Team and (humanoid ~= nil) and (humanoid.Health >= 0) and not Hits[Character] then
						Hits[Character] = true
						local RagdollScript = script.Ragdoll:Clone()
						game:GetService("Debris"):AddItem(RagdollScript,2)
						RagdollScript.Parent = humanoid.Parent
						RagdollScript.Enabled = true
						script.Contact:Play()
						Humanoid:TakeDamage(30)
						local VectorForce = Instance.new("VectorForce",humanoid.Parent.Torso)
						local Attachment = Instance.new("Attachment",humanoid.Parent.Torso)
						VectorForce.Attachment0 = Attachment
						VectorForce.Force = Vector3.new(0,300,6000)
