In this tutorial we will create a Simple SpriteSheet Animation. Pygame is a cross-platform set of Python modules designed for creating games. It includes computer graphics and sound libraries designed to be used with the Python programming language. This is a good opportunity for beginners to learn Pygame first when it comes in developing some games. So let's now do the coding...

Getting Started

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

After Python IDLE's is installed, open the command prompt then type "python -m pip install pygame", and hit enter.

Importing Modules

After setting up the installation, run the IDLE and click file and then new file. After that a new window will appear containing a black file this will be the text editor for the python.

Then copy code that I provided below and paste it inside the IDLE text editor

1. import
   
   pygame,
   
   sys
   
   ,
   
   os
   
2. from
   
   pygame.locals
   
   import
   
   *
   

Writing The Variables

We will assign the a certain variables that we will need to declare later in the main loop. To do that just kindly write this code inside your text editor.

1. #Game Initialization
   
2. pygame.init
   
   (
   
   )
   
3. 
   
4. #Center the Game Application
   
5. os
   
   .environ
   
   [
   
   'SDL_VIDEO_CENTERED'
   
   ]
   
   =
   
   '1'
   
6. 
   
7. # Game Resolution
   
8. screen_width=
   
   800
   
9. screen_height=
   
   600
   
10. screen=
    
    pygame.display
    
    .set_mode
    
    (
    
    (
    
    screen_width,
    
    screen_height)
    
    )
    
11. 
    
12. # Color
    
13. black=
    
    (
    
    0
    
    ,
    
    0
    
    ,
    
    0
    
    )
    
14. white=
    
    (
    
    255
    
    ,
    
    255
    
    ,
    
    255
    
    )
    
15. 
    
16. # Fonts
    
17. font=
    
    "fonts/Gamer.ttf"
    
18. 
    
19. # Framerate
    
20. clock=
    
    pygame.time
    
    .Clock
    
    (
    
    )
    
21. fps=

24. # Image Files
    
25. image=
    
    pygame.image
    
    .load
    
    (
    
    "images/sprite.png"
    
    )
    
26. imageSize=
    
    image.get_size
    
    (
    
    )
    
27. horiz_cell=
    
    6
    
28. vert_cell=
    
    1
    
29. cell_width=
    
    imageSize[
    
    0
    
    ]
    
    /horiz_cell
    
30. cell_height=
    
    imageSize[
    
    1
    
    ]
    
    /vert_cell
    
31. 
    
32. cell_list=
    
    [
    
    ]
    
33. 
    
34. cell_position=
    
    0
    
35. 
    
36. # Slicing The Sprite Sheet
    
37. for
    
    y in
    
    range
    
    (
    
    0
    
    ,
    
    imageSize[
    
    1
    
    ]
    
    ,
    
    int
    
    (
    
    cell_height)
    
    )
    
    :
    
38. for
    
    x in
    
    range
    
    (
    
    0
    
    ,
    
    imageSize[

    ]
    
    ,
    
    int
    
    (
    
    cell_width)
    
    )
    
    :
    
39. surface =
    
    pygame.Surface
    
    (
    
    (

    y,
    
    cell_width,
    
    cell_height)
    
    )
    
42. cell_list.append
    
    (
    
    surface)
    

Declaring Methods

We will now declare some methods to make it easier to call it in the main functions. This contains several function that can be use all through.

1. # Methods
   
2. def
   
   text_format(
   
   text,
   
   textFont,
   
   textSize,
   
   textColor)
   
   :
   
3. font=
   
   pygame.font
   
   .Font
   
   (
   
   textFont,
   
   textSize)
   
4. newText=
   
   font.render
   
   (
   
   text,
   
   0
   
   ,
   
   textColor)
   
5. return
   
   newText
   

Main Function

This is the Main Code for the Pygame application. The code contains a several function that will allow to render the application. To do that just write this code inside the IDLE text editor.

1. # Main Loop
   
2. while
   
   True
   
   :
   
3. for
   
   event in
   
   pygame.event
   
   .get
   
   (
   
   )
   
   :
   
4. if
   
   event.type
   
   ==
   
   pygame.QUIT
   
   :
   
5. pygame.quit
   
   (
   
   )
   
6. sys
   
   .exit
   
   (
   
   )
   
7. 
   
8. if
   
   cell_position <
   
   len
   
   (
   
   cell_list)
   
   -1
   
   :
   
9. cell_position+=
   
   1
   
10. else
    
    :
    
11. cell_position=
    
    0
    
12. title=
    
    text_format(
    
    "Python - Pygame Simple SpriteSheet Animation"
    
    ,
    
    font,
    
    40
    
    ,
    
    white)
    
13. titleRect=
    
    title.get_rect
    
    (
    
    )
    
14. screen.blit
    
    (
    
    title,
    
    (
    
    screen_width/2
    
    - (
    
    titleRect[
    
    2
    
    ]
    
    /2
    
    )
    
    ,
    
    50
    
    )
    
    )
    
15. screen.blit
    
    (
    
    cell_list[
    
    cell_position]
    
    ,
    
    (
    
    300
    
    ,
    
    200
    
    )
    
    )
    
16. pygame.display
    
    .update
    
    (
    
    )
    
17. pygame.display
    
    .set_caption
    
    (
    
    "Python - Pygame Simple SpriteSheet Animation"
    
    )
    
18. clock.tick
    
    (
    
    fps)
    

There you have it we successfully created a Simple SpriteSheet Animation using Pygame. I hope that this simple tutorial help you to what you are looking for and enhance your programming capabilities. For more updates and tutorials just kindly visit this site. Enjoy Coding!!
