Space Race

Multiplayer racing game powered by PubNub.

Multiplayer Gaming Revenue 2016

Playing a game alone is not nearly as fun as playing with your friends and that's one reason why massively multiplayer online games (MMOs) are a huge revenue stream that continues to grow rapidly every year. In June 2018 consumers spent an estimated $9.1 billion digitally across all platforms [on MMOs], compared to $7.9 billion last June.

The design of online games can range from simple text-based environments to incredibly complex virtual worlds. A few other examples of popular online multiplayer games types include first-person shooters (FPS), real-time strategy games (RTS), and multiplayer online battle arena games (MOBA).

This project is intended to show how PubNub can be used to create a real-time multiplayer game. PubNub is perfect for powering multiplayer games because it makes it easier to build a fast and scalable multiplayer game. In this game PubNub is used to manage the players in the game lobby and to transmit game data. The game is built in Go using the PubNub Go SDK and is cross platform. You can learn more about how this game was built from the blog post.

How To Play

  1. The first player to enter a lobby becomes the host. The second player to enter becomes the guest.

  2. Both players need to enter the same lobby name.

  3. When both players have joined a lobby the game will start after a 3 second delay (get your fingers ready).

  4. After the game starts, alternate pressing SPACE and the RIGHT ARROW KEY to advance your progress bar.

  5. The first player to 100% wins the game.

  6. You can leave the game while playing by pressing ESC. If you leave the game then the other player wins automatically.

Limitations

  • If the terminal window is too small, or if the font is too big, the progress bars won't render correctly. Make the window bigger and then press command+k to refresh.

  • The lobby is kept simple by design so it can be used as a seed project. The lobby may not always be able to start a game in some edge cases. If you have problems starting a game try restarting the game for both players and use a new lobby name.
