The sending device now has enough information to send the packet to the receiving device.Р”Р„RP request packets are sent to the broadcast addresses (FF:FF:FF:FF:FF:FF for the Ethernet broadcasts and 255.255.255.255 for the IP broadcast).

All devices on a local network segment see the message, but only the device that has that IP address responds with the ARP reply message containing its MAC address.

The device sends an ARP request message containing the IP address of the receiving device. The sending device uses ARP to translate IP addresses to MAC addresses. It is used when a device wants to communicate with some other device on a local network (for example on an Ethernet network that requires physical addresses to be known before sending packets). This then ends the while loop, as is_running is now False and the script moves on to the final line: pygame.ARP (Address Resolution Protocol) is a network protocol used to find out the hardware (MAC) address of a device from an IP address. This will make it so that when the user presses the exit button in the top corner, the event with the type pygame.QUIT occurs. These are the next 2 lines: if event.type = pygame.QUIT: Which basically goes through a list of events, our event queue.

We can get these events from the event queue with this for loop: for event in (): Pygame handles these events through an event queue. In it's most basic form, pygame has 'events' which takes user input, for example a button press or mouse click. Which will be running throughout the whole game. So that we can start off our while loop: while is_running: To start this off we make a variable and make it True: is_running = True The next few lines are what's called a 'game loop'. Without this line, the user wouldn't see anything on their pygame screen. This basically makes everything we have drawn on the screen Surface become visible and updates the contents of the entire display. This is a function which fills the Surface object, our screen, with the colour red. We then give this command: SCREEN.fill(RED)

The a parameter sets the alpha value of the colour. Where the r parameter sets the red value of the colour, the g parameter sets the green value of the colour and the b parameter sets the blue value of the colour. The pygame.Color class normally goes by this format: COLOUR = (r, g, b, a) When defining colours we put in 3 values that range between 0 and 255. We then use this function to change the name of the window to My Game: _caption('My Game')Р”Р„fterwards we define 6 colours that can be used in our window: WHITE = (255, 255, 255) Note how the parameters for this function are the WIDTH and HEIGHT constants defined earlier. The function used in SCREEN, _mode((WIDTH, HEIGHT)), will set the mode of the display and return a Surface object. The WIDTH and HEIGHT constants are used to create a window, which would have a width of 300 pixels and a height of 200 pixels. We then define some constants here: WIDTH = 300 This is used to initialise all of the pygame modules. We then initialise all the imported pygame modules: pygame.init() SCREEN = _mode((WIDTH, HEIGHT))Р”Р„s we do with any module in python we need to import pygame: import pygame
