Wednesday - Friday (9/28/11 - 9/30/11)

Agenda:

• Begin work on your Basic Frogger Game
  1. Give your game a simple background
  2. You will need several sprites.
  3. 1 player sprite will be the player and it will cross the screen by using the keyboard.
  4. 3-5 enemy sprites will be used to move back and forth vertically across the screen (the number depends on how big you make them)
  5. When you play your game, you want to cross the entire screen without hitting the enemy sprites.
  6. Start the player off with 3 lives (HINT: use a variable)
  7. If you hit any of the enemy sprites:
     1. Subtract one life away
     2. Say "Ouch!"
     3. Move the player back to its starting location
  8. If lives hits 0, then say "Game Over" and end the game
  9. If the player reaches the other side of the screen, then say "You win!"
     • Hint: You can use all sorts of different ways to detect how you hit the other side of the screen
     • Create a long sprite that you detect hitting OR...
     • Check the y-coordinate of the sprite and if it is greater than the upper bound of the screen
