This game was made by a 13 year old boy as part of his computer programming class. It is a 2d scroller game with walking animation of the player. The main assignment is to slice up a 30 cell animation sprite sheet using the pygame library blit. The individual cells of the animation are stored in a list of 30 elements.
Run the game on your desktop with:
$ python main.py
If you want to run the game on your android phone, get the Android apk package from the android/ sub-directory
Install it on your phone in many different ways. For example, use a USB cable to transfer the file and then touch it to install.
You can also use send the file to your gmail account.
On your phone, you need to allow installation from "Unknown sources."
- Parallax scrolling- The back layer runs slower than the front layer, giving the illusion of depth.
- Main background is "one giant image." The background is a photograph that was run through a design filter on Gimp. The game does not use a tile map loader.
- Begin learning the basics of the pygame.sprite.Sprite class.
This is the key section of the lesson:
for y in range(0, sheet_height, player_height):
for x in range(0, sheet_width, player_width):
player = pygame.Surface((player_width, player_height))
player.blit(player_sheet, (0, 0), (x, y, player_width, player_height))
color_key = player.get_at((0, 0))
player.set_colorkey(color_key)
small_player = pygame.transform.scale(player, (int(player_width / 2.5), int(player_height / 2.5)))
player_list.append(small_player)
player_position = 0Someone asked me how to use the player in the main game loop. Here's the bit of code for that.
## blit the player
if player_position < len(player_list):
player_position = player_position + 1
else:
player_position = 0
windowSurface.blit(player_list[player_position - 1], player_rect)Most of the code is in one large block. My son is learning to put code into classes and organize the classes into modules.
