Hi, aspiring coders! Today I will show you guys, how to build one of the most popular games that almost everyone plays while they are offline. If your guessing which game then I am talking about Google Chrome’s Dino game. But, Our Dino game is a modified form of Chrome’s version as its colored. Now let’s go directly on to the tutorial of building it.

Requirements:

  • A PC with any OS installed in it.
  • The latest version of Python which can be easily downloaded from https://www.python.org/downloads/[For installing you can check this blog]
  • A good Code IDE [ Prefer using VS Code or Atom]
  • Your focus

Tutorial:

  • Firstly, open your cmd[Command Prompt] and type the following command after installing python from https://pypi.org/project/pygame/
  1. pip install pygame
  2. pip install random2
  • Secondly, copy the following codes provided along with resources that you can get in the download button below.
  • Lastly, run the python code with python main.py command.[Here, main.py is the file name]. That’s it!
