Detect Hit with userinput service

To make it so that clicking on the Stick part of the StarterCharacter model deals damage and increases a Leaderstats value, you can add some code to your onInputBegan function. Here’s an example:

local function onInputBegan(input, _gameProcessed)
	if input.UserInputType == Enum.UserInputType.MouseButton1 and debounce == false then
		debounce = true
		print("The left mouse button has been pressed!")
		
		local Player = game.Players.LocalPlayer
		local Character = Player.Character
		local Humanoid = Character:WaitForChild("Humanoid")
		local Anim = Humanoid:LoadAnimation(Animation)
		
		-- Check if the mouse click hit the Stick part
		local mouseHit = UserInputService:GetMouseLocation()
		local ray = workspace:Raycast(mouseHit.UnitRay.Origin, mouseHit.UnitRay.Direction * 100)
		if ray and ray.Instance == Character.Stick then
			-- Deal damage to the player who clicked
			local clickedPlayer = game.Players:GetPlayerFromCharacter(Character)
			local clickedHumanoid = Character:FindFirstChildOfClass("Humanoid")
			if clickedPlayer and clickedHumanoid then
				clickedHumanoid:TakeDamage(10)
				-- Increase Leaderstats value by 1
				local leaderstats = clickedPlayer:FindFirstChild("leaderstats")
				if leaderstats then
					local clicks = leaderstats:FindFirstChild("Clicks")
					if clicks then
						clicks.Value = clicks.Value + 1
					end
				end
			end
		else
			-- Play animation if the mouse click did not hit the Stick part
			Anim:Play()
			wait(0.8)
		end
		
		debounce = false
	end
end

In this code, we first check if the mouse click hit the Stick part using a Raycast. If it did, we get the player who clicked and their Humanoid, and use the TakeDamage() method to deal damage to the player. We then check if the player has a Leaderstats folder, and if so, find the Clicks value and increase it by 1. If the mouse click did not hit the Stick part, we simply play the animation as before. Note that the animation will still play even if the mouse click hits the Stick part, so you may want to modify the code to prevent this if desired. Hope this helps x
