How to make a script that gives you money if you click someone of the criminals team?

I'm developing a game and I need a script that goes inside a tool and if you click someone from the criminal team with it you receive 10k money for example.

You can use the UserInputService.InputBegan event to collect user input, and process it like so:

local Services = {
	UserInput = game:GetService("UserInputService")
}

local function OnUserInputBegan(InputObject, GameProcessedEvent)
	if GameProcessedEvent then
		return
	end

	if InputObject.UserInputType ~= Enum.UserInputType.MouseButton1 then
		return
	end

	-- Code here!
end

Services.UserInput.InputBegan:Connect(OnUserInputBegan)

Next, you'd want to get the player that the user is clicking on. You can accomplish this by using the old and outdated PlayerMouse API via Player:GetMouse(), and accessing PlayerMouse.Target, or, alternatively, casting a ray from the Camera's 3D point in the direction of the mouse (you can access positional mouse information via InputObject in our example.
