Game Summary

• The magic mushrooms have been stolen! Get as many
  back as possible. But be careful, get at least
  25, because youre working for the mafia.
• Play the game by moving your car up and down with
  the i and k keys, while the track and the
  mushrooms move right to left.
• Failing to recover at least 25 of the mushrooms
  on the screen, or crashing into the black walls
  at the top and bottom, results in a loss.
• Recovering one fourth or more of the mushrooms in
  a level makes the level increase. Finish all
  three levels to win the game.

Process of Making the Game

• Make the game extend GameLoop, making it part of
  Jam Jenkins gaming package, and create a help
  screen to be filled in later.
• Create a sprite (a red rectangle) that appears on
  the screen for the players car.
• In the advanceFrame method, which changes whats
  on the screen over time, allow the player to
  press keys (i and k) to move the car up and
  down.
• Make rectangle sprites for the three edges of the
  road, the two on the top and bottom rotated so
  that they angle toward each other towards the
  right side of the screen (the third is a vertical
  line connecting the right ends of the other two).
• 5. Add a tracker to the edges so that they move
  right to left.

Process (continued)

• Make StringSprites that say Game Over and You
  Win.
• Make a method to detect collisions between the
  car and the edges.
• Make the game kill all sprites when a collision
  is detected call the methods for the Game Over
  screen when the collision is with the edges on
  the top and bottom, and the You Win screen for
  the vertical line.
• Make a two-dimensional array of Ellipse2D sprites
  (the mushrooms) that fits within the three
  edges, conforming to the shape of the space.
• Add a tracker to each mushroom that makes them
  all move at the same speed and directions as the
  edges of the road.

Process (continued)

• In the collisions method, make the mushrooms
  disappear when they collide with the car.
• Make, and display, a score that increases by one
  for each mushroom collected.
• Make the game over screen appear when 25 of the
  mushrooms have not been collected.
• Make the mushrooms appear at random spots within
  the array, filling about one third of the spaces.
• Make a variable for what level the player is on.

Process (continued)

• 16. Create an introduction screen with text
  flying in.
• 17. Make the level increase when the level,
  which starts at zero, is less than two when the
  finish line is reached, and dont display the you
  win screen until level two is completed.
• 18. Make the number of mushrooms and speed of
  the game increase when the level increases.
• Add sounds for starting, winning, losing, and
  level completed.
• Update the help files to tell people how to play
  the game.
• Export the game to the website.

Bugs Encountered and Fixed

• The edges of the road were gravitating down when
  trackers were added. The tracker was taken from
  another game (Pong Deathmatch) we took gravity
  out of the tracker.
• The starting sound was playing before the game
  was started. There was a bug in the gaming
  package Jam fixed it on our computer.
• The mushroom array wasnt taking the shape of the
  road. We added complicated equations calculated
  by the instructor, which made sense to us, but
  would have been difficult to create ourselves
• Mushrooms that did not appear on the screen
  because of the random number generator were still
  being collected. We had been making the sprites
  invisible instead of killing them.
• The game was starting before the sprites were
  appearing on the canvas. We tried many things to
  make the game more efficient, but the problem
  remained. We fixed it by moving the road further
  to the right to compensate for the invisible
  movement.
