Example code and programs

There are many example programs available for download at:
http://ProgramArcadeGames.com/python_examples/en/python_examples.zip

Here is a brief description of what is available:

1.1 Text examples

Example programs that don't involve graphics:

• Program that calculates miles-per-gallon.
  calculate_miles_per_gallon.py
• Calculates the kinetic energy of an object.
  calculate_kinetic_energy.py
• Simple example if statements.
  if_statement_examples.py
• Simple example for loops.
  for_loop_examples.py
• Simple example while loops. (Chapter 4
  while_loop_examples.py
• Simple example for encrypting text.
  simple_encryption.py
• Simple example for decrypting text.
  simple_decryption.py
• Binary and linear searches.
  searching_example.py
• Property check examples.
  property_check_examples.py

1.2 Graphics examples

Programs that show how to use graphics:

• This opens up a blank pygame window. It is a good template to use when starting a new program.
  pygame_base_template.py
• This file demonstrates setting up a window and drawing rectangles, polygons, text, and other basic shapes.
  simple_graphics_demo.py
• See how to rotate text.
  text_rotate.py
• Demos all the commands in the draw module.
  draw_module_example.py
• Animate a bouncing rectangle around the screen.
  bouncing_rectangle.py
• Animate a several bouncing balls.
  bouncing_balls.py
• This shows how to use an array to animate and track multiple objects. In this case, snow flakes.
  animating_snow.py
• This file draws a snowman inside of a function. The program can then call the draw snowman function and draw several snowmen easily.
  functions_and_graphics.py
• Move an object with the mouse.
  move_mouse.py
• Move an object with the keyboard.
  move_keyboard.py
• Move an object with the game controller.
  move_game_controller.py
• Show how to read everything off a gamepad/controller/joystick.
  joystick_calls.py
• Display bitmapped images (png, jpg) to a screen. Make sounds.
  bitmapped_graphics.py
• Display a board based on a two-dimensional grid. Useful when creating games like tic-tac-toe, minesweeper, memory-match, connect-four, etc.
  array_backed_grid.py
• Display one or more pages of instruction before the game starts.
  instruction_screen.py
• Plays background music. When the music is over, an event is triggered and a different song starts. The music is included in the downloadable zip file, or you can follow the links in the comments to download the music.
  background_music.py
• Shows how to display a centered "Game Over" message, and stop game play when a game is over.
  game_over.py
• Display a line sweeping around in a circle like a radar.
  radar_sweep.py
• Count up and count down timers.
  timer.py
• Using recursion to make nested rectangles.
  recursive_rectangles.py
• Using recursion to make fractals.
  fractal.py
• Put a timer on the screen.
  timer.py

1.3 Sprite examples

How to use sprites:

• Move a sprite with the mouse and collect blocks.
  sprite_collect_blocks.py
• Same as collect blocks example, but all the sprites move.
  moving_sprites.py
• Same as collect blocks example, but you can move the sprite by clicking to pick them up.
  pick_up_blocks.py
• Rather than just move down, these sprites bounce.
  moving_sprites_bounce.py
• Prior example too boring? Get the sprites to move in circles.
  sprite_circle_movement.py
• Expands the prior example to show how to manage a game with levels. Level advances when all the blocks are cleared.
  sprite_collect_blocks_levels.py
• Same as sprite_collect_blocks.py but with a black circle instead of a block.
  sprite_collect_circle.py
• Same as sprite_collect_blocks.py but with a graphic instead of a block.
  sprite_collect_graphic.py
• Same as sprite_collect_blocks.py but with a graphic instead of a block.
  sprite_rotating.py
• Same idea as sprite_collect_blocks.py but uses a Game class to organize the code. This is a more advanced way of organizing the code. It helps if you want to “restart” a game once it is over.
  game_class_example.py
• Move a sprite around the screen with the mouse.
  move_sprite_mouse.py
• Move a sprite with the keyboard in discrete “jumps.”
  move_sprite_keyboard_jump.py
• Move a sprite with the keyboard smoothly and continuously while a key is pressed.
  move_sprite_keyboard_smooth.py
• Move a sprite with a game controller or joystick.
  move_sprite_game_controller.py
• Basic Pong game using two game controllers.
  pong.py
• How to manage bullets with sprites.
  bullets.py
• How to aim bullets.
  bullets_aimed.py
• Control a snake as it moves around the screen.
  snake.py

1.4 Platformer examples

Progressively more complex examples for a platformer game:

• Move a sprite around the screen, but not let it move through walls.
  move_with_walls_example.py
• More complex version of prior example, with multi-colored walls, and multiple rooms.
  maze_runner.py
• Get the player to jump off platforms.
  platform_jumper.py
• Like platform jumper, but scroll side to side.
  platform_scroller.py
• Make those platforms move!
  platform_moving.py
• A multi-file example that shows a platformer using sprite sheets.
  Sprite Sheets

Also some longer example programs are included.
