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:

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()

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.

PyGame : Install pygame 2.0 from GitHub on Linux.
