Theme Development

• The theme of the game has stayed the same. The
  UFO try to catch sheep while avoiding shepherds
  and UFO Shooters.
• The shepherds are now represented by German
  Shepherds because it is easier to find an image
  of a German Shepherd that is still discernable at
  a small size.
• Levels have not yet been implemented.

Classes and Documentation

• SheepLoop and GameLoop written
• SheepLoop extends GameLoop
• Sprites created
• Walls
• UFO, Sheep, Shepherds (Tracker)
• Shadow (Tracker)
• Cloud, CloudFlipped (for continuity of screen)
• Road

Walls

• The walls were divided mathematically to take up
  a third of the screen so that there would be the
  illusion of 3D in 2D.
• The sheep can only travel within the one third of
  the screen and the UFO can only travel in the
  rest of the two thirds. The walls were
  deliberately made thick enough so that the sheep
  and shepherds, which move in discrete units,
  couldnt jump over the fence.
• The shadow of the UFO can travel down to the
  sheeps dimensions.

6
Randomization

• The Sheep and Shepherds start off from the center
  of the Sheeps rectangle.
• They disperse randomly and their subsequent
  locations are random.
• The next step would be to make each of their
  velocities random with respect to each other so
  that the movements appear even more dispersed.

7
Collision Handler

• Collision handler installed
• Whenever the shadow of the UFO hits one or more
  objects, all objects within the shadow are
  counted in the collision.
• Therefore, if you hit both a sheep and a
  shepherd, you would simultaneously gain 20 points
  and lose 20 points.
• Ideally, this makes the game more difficult.

8
Shadows and Shading

• I made the UFO shadow transparent by changing the
  RGB levels so that the sheep will be colored by
  the shadow instead of colored over by the shadow.
  (Thank you Jam).
• I then made the images of the sheep and
  shepherds and UFO distinct by taking out the
  background coloring (Thank you Chris for using
  Photoshop to crop my photos).

9
Backgrounds

• I created distinct backgrounds for the sheep
  rectangle and the rest of the game.
• The sheep rectangle was colored in with grass.
  This was done by cropping and rotating Jams Game
  Engine Scroller Sample.
• The scrolling Cloud background for the sky was
  made by taking the Cloud.JPG and implementing
  Jams SimpleScroller.

10
AdvanceFrame

• There is no time limit yet for the game. I need
  to implement this.
• When the UFO Shadow is over a sheep or shepherd,
  the player clicks on the sheep and/or shepherd
  with the mouse to capture it/them.
• /- 20 points for each click.

11
Sounds and Images

• I have implemented a Baa for whenever a sheep
  is captured.
• I need to implement the following
• Background music
• German shepherd bark
• UFO Shooters
• UFO Shooters shooting sounds.

Timeline

• So far, I feel that I am on track.
• Before the end of the November, I hope to have a
  fully functional game with 3 Levels.
• I have thought of new enhancements
• Artificial intelligence make the sheep move
  radially from the shadow at a slower rate than
  the space ship can move (Jam Jenkins).
• Network the game into a multi-player sensory
  experience!
