These blocks are so you can connect to the internet, and play with other people that are playing the same project you are right now! -------------------- This would be great because: Mulitplayer can be hard to script, and with this, you wouldn't have to script anything but tell it to connect. If you don't have any siblings that wanna play your game, you can play it with someone else! If someone is in another state or something, you could comment saying to play your game, then they'll have fun and what-not. :D
