PyGame : ovoid with a random pattern.

Here's how to create an ovoid with a random pattern. Run the script several times to see the differences:

import pygame
import random
pygame.init()

# Set up the display window
screen_size = (400, 400)
screen = pygame.display.set_mode(screen_size)
# Set window title
pygame.display.set_caption("Ovoid with Random Pattern")
# Define the ovoid
ovoid_pos = (150, 100)
ovoid_size = (100, 200)

# Create the ovoid surface
ovoid_surface = pygame.Surface(ovoid_size, pygame.SRCALPHA)

# Define the pattern
pattern_size = (random.randint(1, 9), random.randint(1, 9))
pattern_surface = pygame.Surface(pattern_size)
pattern_surface.fill((255, 255, 255))
pygame.draw.line(pattern_surface, (0, 0, 0), (0, 0), pattern_size)

# Create the mask surface
mask_surface = pygame.Surface(ovoid_size, pygame.SRCALPHA)
pygame.draw.ellipse(mask_surface, (255, 255, 255), mask_surface.get_rect(), 0)

# Apply the pattern to the ovoid surface
for x in range(0, ovoid_size[0], pattern_size[0]):
    for y in range(0, ovoid_size[1], pattern_size[1]):
        ovoid_surface.blit(pattern_surface, (x, y))

# Apply the mask to the ovoid surface
ovoid_surface.blit(mask_surface, (0, 0), special_flags=pygame.BLEND_RGBA_MULT)

# Draw the ovoid to the screen
screen.blit(ovoid_surface, ovoid_pos)

# Update the display
pygame.display.flip()

# Wait for the user to close the window
done = False
while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

# Quit pygame properly
pygame.quit()

PyGame : simple web camera !

In this simple tutorial, I'll show you how to use pygame to use it with a webcam.

Let's install the pygame with the pip tool:

C:\PythonProjects\pygamecamera001>pip install pygame --user
Collecting pygame
  Downloading pygame-2.2.0-cp311-cp311-win_amd64.whl (10.4 MB)
     ---------------------------------------- 10.4/10.4 MB 9.0 MB/s eta 0:00:00
Installing collected packages: pygame
Successfully installed pygame-2.2.0

This is the source code for web camera:

import pygame.camera
import pygame.image
import sys

pygame.camera.init()

cameras = pygame.camera.list_cameras()

webcam = pygame.camera.Camera(cameras[0])

webcam.start()

img = webcam.get_image()

WIDTH = img.get_width()
HEIGHT = img.get_height()

screen = pygame.display.set_mode( ( WIDTH, HEIGHT ) )
pygame.display.set_caption("pyGame webcam")

while True :
    for e in pygame.event.get() :
        if e.type == pygame.QUIT :
            sys.exit()
    screen.blit(img, (0,0))
    pygame.display.flip()
    img = webcam.get_image()

PyGame : simple digital clock.

This is the source code I used and is very simple.

import pygame
import time

# init the Pygame
pygame.init()

# this set the window size
window_size = (640, 100)

# this create the window
screen = pygame.display.set_mode(window_size)

# this set the title of the window
pygame.display.set_caption("Digital Clock")

# this fill the background color to white
screen.fill((255, 255, 255))

# settings for the font and size
font = pygame.font.Font(None, 36)

# the game loop area
running = True
while running:
# use an event to quit
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # get the current time
    current_time = time.strftime("%H:%M:%S")

    # render the time as text
    text = font.render(current_time, True, (0, 0, 0))

    # clear the screen
    screen.fill((255, 255, 255))

    # draw the text on the screen
    screen.blit(text, (10, 10))

    # update the screen
    pygame.display.flip()

# quit Pygame application
pygame.quit()

The result of the running source code is this:

News : pygame-menu version 4.3.2.

This python package let you to use a menu for pygame.

You can find it on this webpage and documentation on this webpage.

This is simple to use it:

You can install easy like any python package using the pip3 python tool:

pip3 install pygame-menu==4.3.2 --user

I created a python file named pygame-menu_001.py and I add this simple example to test it:

import pygame
import pygame_menu
from pygame_menu import Theme
pygame.init()
surface = pygame.display.set_mode((640, 480))

def set_difficulty(value, difficulty):
    # Do the job here !
    pass

def start_the_game():
    # Do the job here !
    pass

mytheme = pygame_menu.themes.THEME_BLUE.copy()
mytheme.title_background_color=(0, 19, 76)
mytheme = Theme(widget_font=pygame_menu.font.FONT_FRANCHISE)

menu = pygame_menu.Menu('Main menu', 400, 300,
                       theme=mytheme)

menu.add.text_input('User :', default='catafest')
menu.add.selector('Difficulty :', [('Hard', 1), ('Easy', 2)], onchange=set_difficulty)
menu.add.button('Play', start_the_game)
menu.add.button('Quit', pygame_menu.events.EXIT)

menu.mainloop(surface)

This is the result of the running script:

PyGame : Testing Pygame GUI - part 03.

In this article tutorial I show you how can create a progressbar and set it with value 76.

This example looks like this:

The source code is not very complicated and is very readable for any developer with minimal knowledge in the programming area.

import pygame
import pygame_gui

pygame.init()

pygame.display.set_caption('Quick Start')
window_surface = pygame.display.set_mode((640, 480))

background = pygame.Surface((640, 480))
background.fill(pygame.Color('#0076AB'))

manager = pygame_gui.UIManager((640, 480))

print(dir(pygame_gui.elements.UIProgressBar))
myProgressBar = pygame_gui.elements.UIProgressBar(relative_rect=pygame.Rect((50, 100), (300, 40)),
	visible= 1,
        manager=manager)
myProgressBar.set_current_progress(76)
clock = pygame.time.Clock()
is_running = True

while is_running:
    time_delta = clock.tick(60)/1000.0
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            is_running = False

        if event.type == pygame_gui.UI_BUTTON_PRESSED:
            if event.ui_element == hello_button:
                print('Hello World!')

        manager.process_events(event)

    manager.update(time_delta)

    window_surface.blit(background, (0, 0))
    manager.draw_ui(window_surface)

    pygame.display.update()

PyGame : Testing Pygame GUI - part 02.

I repeat, Pygame GUI is a module to help you make graphical user interfaces for games written in pygame.

In this short tutorial I will show you a source code that creates a HealthBar.

This example looks like this:

The source code is not very complicated and is very readable.

import pygame
import pygame_gui

pygame.init()

pygame.display.set_caption('Quick Start')
window_surface = pygame.display.set_mode((640, 480))

background = pygame.Surface((640, 480))
background.fill(pygame.Color('#0076AB'))

manager = pygame_gui.UIManager((640, 480))

HealthBar = pygame_gui.elements.UIScreenSpaceHealthBar(relative_rect=pygame.Rect((50, 100), (300, 40)),
	visible= 1,
        manager=manager)
clock = pygame.time.Clock()
is_running = True

while is_running:
    time_delta = clock.tick(60)/1000.0
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            is_running = False

        if event.type == pygame_gui.UI_BUTTON_PRESSED:
            if event.ui_element == hello_button:
                print('Hello World!')

        manager.process_events(event)

    manager.update(time_delta)

    window_surface.blit(background, (0, 0))
    manager.draw_ui(window_surface)

    pygame.display.update()

PyGame : Testing Pygame GUI - part 01.

Pygame GUI is a module to help you make graphical user interfaces for games written in pygame.

The module is firmly forward-looking and is designed to work on Pygame 2 and Python 3.

You can read more about these features for this python package on the official website.

This is a simple interface with python and python pygame and pygame_gui python packages.

You can see a simple example on my GitHub account.
