How To Create a Flappy Bird Game Using Python ? Easy Step by Step 👍

FLAPPY  BIRD  GAME :

 bash

pip install pygame

Step 1: Import Libraries

Start by importing the necessary libraries:

python
import pygame
import random
import sys
from pygame.locals import *

Step 2: Initialize Game Variables

Set up the screen, clock, and colors:

python
# Initialize pygame
pygame.init()

# Set up the screen
SCREEN_WIDTH = 400
SCREEN_HEIGHT = 600
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
clock = pygame.time.Clock()

# Set up colors
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)

Step 3: Load Game Assets

Load images and set up the game’s assets like bird, background, and pipes:

python
# Load images
bird_image = pygame.image.load('bird.png')
background_image = pygame.image.load('background.png')
pipe_image = pygame.image.load('pipe.png')

# Scale images
bird = pygame.transform.scale(bird_image, (34, 24))
background = pygame.transform.scale(background_image, (SCREEN_WIDTH, SCREEN_HEIGHT))
pipe = pygame.transform.scale(pipe_image, (52, 320))

Step 4: Create Game Functions

Create functions to handle game logic:

1. Drawing the game elements:

python
def draw_objects(bird_y, pipe_x, pipe_y):
    screen.blit(background, (0, 0))
    screen.blit(bird, (50, bird_y))
    screen.blit(pipe, (pipe_x, pipe_y))
    screen.blit(pipe, (pipe_x, pipe_y + 420))

2. Collision detection:

python
def check_collision(bird_y, pipe_x, pipe_y):
    if bird_y > SCREEN_HEIGHT - 40 or bird_y < 0:
        return True
    if pipe_x < 84 and (bird_y < pipe_y + 320 or bird_y > pipe_y + 420):
        return True
    return False

3. Main game loop:

python
def main_game():
    bird_y = SCREEN_HEIGHT // 2
    bird_movement = 0
    gravity = 0.25

    pipe_x = SCREEN_WIDTH
    pipe_y = random.randint(-100, 100)
    pipe_velocity = -4

    score = 0

    while True:
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            if event.type == KEYDOWN:
                if event.key == K_SPACE:
                    bird_movement = -6

        bird_movement += gravity
        bird_y += bird_movement

        pipe_x += pipe_velocity

        if pipe_x < -50:
            pipe_x = SCREEN_WIDTH
            pipe_y = random.randint(-100, 100)
            score += 1

        if check_collision(bird_y, pipe_x, pipe_y):
            main_game()

        draw_objects(bird_y, pipe_x, pipe_y)

        pygame.display.update()
        clock.tick(30)

Step 5: Run the Game

Finally, start the game loop:

python
if __name__ == "__main__":
    main_game()

Step 6: Add Bird and Pipe Images

Make sure you have the following image files in the same directory as your script:

• bird.png
• background.png
• pipe.png

These images can be any suitable representation of the bird, background, and pipes.

Step 7: Run the Game

Run your Python script, and you should see the Flappy Bird game running!
