Snake Battle

Play Snake with two players

THIS GAME IS ALSO PLAYABLE ON A RASPBERRY PI USING GPIO INPUTS!

Python and Requirements Installation

Windows

• Download the latest Python 2 release from here
• Run the installer (make sure to include pip)
• Open cmd.exe as administrator and install the required packages by running pip2 install <package> or python2 -m pip install <package>

Linux

• Install Python 2 using your package manager
• Open a terminal and install the required packages by running sudo pip2 install <package>

Required Python Packages

• pygame
• RPi.GPIO (only when used on a Raspberry Pi)

Setup Font

Before starting the game go to line 68 and 69 and change None to the path of a font file. If you don't specify a font Pygame will choose a default one.

I recommend using VT323 by Peter Hull

Example

FONT_DB = pygame.font.Font("VT232.ttf", 20) # debug font
FONT_SC = pygame.font.Font("VT232.ttf", TILE_SIZE * 5) # score

Note: You should use an absolute path if you do not run the game from inside the directory

Start Game

Open a terminal / cmd.exe and navigate to this folder then run

python2 snakebattle.py

The game is tested with Python v2.7, feel free to use any other compatible version

Play Game

• Player 1:
  • Turn left: A
  • Turn right: D
• Player 2:
  • Turn left: LEFT ARROW
  • Turn right: RIGHT ARROW
• Collect food to grow
• You will lose if you touch your opponent or the window borders
• If both players "lose" at once the longer snake will win

optional arguments:
  -h, --help            show this help message and exit
  -r, --raspi           run snake battle on a raspberry pi
  -s PX, --tilesize PX  the size of a tile
  -t X Y, --tiles X Y   the number of tiles
  -d, --debug           show debug information on the screen
  -f TPS, --fps TPS     framerate in ticks per second
  -b MS, --delay MS     button delay (raspi mode)

Raspberry Pi Mode (--raspi)

Connect buttons to the following GPIO pins (BCM numbering)

• Player 1 Left: 25
• Player 1 Right: 24
• Player 2 Left: 23
• Player 2 Right: 18

Alternatively, you can use other pins and change the pin numbers on lines 23 - 26.
