How to create a memory puzzle game with Python and Pygame (#001)

-

 

In order to create our full game, we first need to set up a window and fill the window with white background color. 

import pygame, sys

from pygame.locals import *



pygame.init()



SCREEN_SIZE = (640,480)



# main screen set up

screen = pygame.display.set_mode(SCREEN_SIZE)

pygame.display.set_caption('Puzzle Game')



# color setup

WHITE = (255,255,255)

screen.fill(WHITE)



# set backgroud color to white

while True:

      for event in pygame.event.get():

            if event.type == QUIT:

                  pygame.quit()

                  sys.exit()

      

      pygame.display.update()

Explanation

import pygame, os

from pygame.locals import *

We need to import all the necessary modules into our source file, which is the same for all pygame applications.

pygame.init()

After importing all the necessary modules, we need to initialize the pygame module.

SCREEN_SIZE = (640,480)

# main screen set up

screen = pygame.display.set_mode(SCREEN_SIZE)

pygame.display.set_caption('Puzzle Game')

Next, we just create the main game screen with a screen size 640*480 and leave other parameters to the pygame moudle to decide. And also we need to set the window caption to whatever name you want.

# color setup

WHITE = (255,255,255)

screen.fill(WHITE)

For now, we just need one white color which is the background color of the main window and set its background color to white.

# set backgroud color to white

while True:

      for event in pygame.event.get():

            if event.type == QUIT:

                  pygame.quit()

                  sys.exit()

Every game should have a game loop, our game loop is the while loop. In oder to quite the game safely, we need to use pygame's event handling mechanism. We iterate through all the events returnted by the pygame.event.get() method, if the event is a quit event, we quit the game by invoking pygame.quit() and sys.exit().

      pygame.display.update()

Finally, we need to update the display screen in order to make the changes visible to our eyes by using pygame.display.update(), otherwise won't see any changes.

And now, press F5 or run the module inside your IDLE. You should see the following screen shot.


Congratulations, we have created our main game dislpay. Now, you can quit the screen by clicking the 'x' on the right corner of the game window.

How to create a memory puzzle game with Python and Pygame (#005)

First look at the following code: import time # create Font object text_font = pygame . font . SysFont( 'arial' , 50 ) # create a list that stores two pos that going to compare to each other pos_to_compare_list = [] # create a list that stores all the pos that matched pos_matched = [] # set backgroud color to white while True : for event in pygame . event . get(): if event . type == QUIT: pygame . quit() sys . exit() elif event . type == MOUSEBUTTONDOWN: (x,y) = pygame . mouse . get_pos() pos = check_click(x,y, square_pos) if pos: text_surface = text_font . render(board[pos[ 0 ]][pos[ 1 ]], True , WHITE) if len (pos_to_compare_list) < 2 : if pos not in pos_to_compare_list: pos_to_compare_list . append(pos) ...

Table of Contents Preparation Introduction Import modules and define contants Create the main game screen Creae the data structure of the board Let's draw the tiles The game logic Define the missing functions Preparation In this tutorial, we are gonna use Python 3.8 and Pygame v1.96.  For the installation of Python and Pygame, please follow the documents found on each webiste. Python: https://www.python.org/ Pygame: https://www.pygame.org/ Introduction As you can see from the picture above, we create a board with 15 green tiles and one white tile which represent a empty slot. Our gaol is to place all the 15 green tiles back into its sorted order, namely: A B C D E F G H I J K L  M N O If we click on the tile "F", the tile will slide down south. And if all the tiles are back into their sorted order, you won the game and quit the game. That's pretty much the gist of the game, later you could add other features to the game. Import modules and define contatnts impor...

Introduction to multitasking with Python #003 gevent (2020 tutorial)

  1 . Review of Iterator In python, we could achieve multitasking through another way by using gevent module. Howerver before introducing gevent, we have to review the concept of iterator. You may have used python for loop millions of times: for i in Iterable:     print(i) We have learned several iterable objects, str, list, tuple, dict and set. Those iterable objects or sequences could be used with the for loop. And we take that for granted. But look at the following example: >>> for i in 100: print(i) Traceback (most recent call last):   File "<pyshell#2>", line 1, in <module>     for i in 100: TypeError: 'int' object is not iterable >>>   Why cannot int type be used with for loop in Python and how could you make an object iterable and be used with for loop? Now, let's make an iterable object that could be used with for loop. We could use isinstance() built-in method to check whether an object is iterable or not. ...
