Check which MouseButtons are Pressed

This example checks if the user pressed MouseButton1, MouseButton2, or both mouse buttons on UserInputService/InputBegan|InputBegan.

The example can be extended to behave differently depending on which mouse buttons are pressed.

local UserInputService = game:GetService("UserInputService")

-- InputBegan is a UserInputService event that fires when the player
-- begins interacting via a Human-User input device
UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
-- Returns an array of the pressed MouseButtons
local buttons = UserInputService:GetMouseButtonsPressed()

	local m1Pressed, m2Pressed = false, false
	for _, button in pairs (buttons) do
		-- Check if MouseButton1 is pressed
		if (button.UserInputType.Name == "MouseButton1") then
			print("MouseButton1 is pressed")
			m1Pressed = true
		end

		-- Check if MouseButton2 is pressed
		if (button.UserInputType.Name == "MouseButton2") then
			print("MouseButton2 is pressed")
			m2Pressed = true
		end
		
		-- Check if both MouseButton1 and MouseButton2 are pressed
		if (m1Pressed and m2Pressed) then
			print("Both mouse buttons are pressed")
		end
	end
end)
