Python 3 PyGame Google Chrome Dinosaur (T-Rex) Dino Runner Game GUI Script Desktop App Full Project For Beginners

Python 3 PyGame Google Chrome Dinosaur (T-Rex) Dino Runner Game GUI Script Desktop App Full Project For Beginners

 

 

Welcome folks today in this blog post we will be building a chrome dinosaur game in python using pygame library. All the full source code of the application is given below.

 

 

Get Started

 

 

In order to get started you need to install the following libraries using the pip command as shown below

 

pip install pygame

 

After installing this library you need to make an main.py file and copy paste the following code

 

main.py

 

import pygame
import os
import random
pygame.init()

# Global Constants
SCREEN_HEIGHT = 600
SCREEN_WIDTH = 1100
SCREEN = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

           pygame.image.load(os.path.join("Assets/Dino", "DinoRun2.png"))]
JUMPING = pygame.image.load(os.path.join("Assets/Dino", "DinoJump.png"))

           pygame.image.load(os.path.join("Assets/Dino", "DinoDuck2.png"))]

                pygame.image.load(os.path.join("Assets/Cactus", "SmallCactus2.png")),
                pygame.image.load(os.path.join("Assets/Cactus", "SmallCactus3.png"))]

                pygame.image.load(os.path.join("Assets/Cactus", "LargeCactus2.png")),
                pygame.image.load(os.path.join("Assets/Cactus", "LargeCactus3.png"))]
