Three Simple Ways to Create Your Own Dino Run Game in Python
by Dark SoulzJuly 20th, 2020
Too Long; Didn't Read
The game is a modified form of Google Chrome's Dino game as its colored. It's a modified version of Chrome's version as its colors are different. Now let's go directly on to the tutorial to create a dino run game in python. The class is called 'Dino Run by Tripura Coders' and the game is created using Python's python-PyPyPy game-making tool. The code is based on the original version of the Google Chrome version of this game.Company Mentioned
Hi, Hackernoon peeps! 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 to create a dino run game in python.
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/
- Secondly, copy the following codes provided along with resources that you can get in the download button below.
- pip install pygame
- pip install random2
- Lastly, run the python code with python main.py command.[Here, main.py is the file name]. That's it!
