Object of the Game

Game Scene Set-Up

Some rooms have one door, some do two. There is a corridor between some rooms, but some rooms are adjacent to each other by a wall, sometimes with a door. In each room, there is a target. In this game, a target is represented by yoda (yoda.d). All targets face a door and located in the middle of the room.

The shooter can wonder around freely as long as he doesn't collide with any game objects. These include rooms, walls, and targets.

(Unfortunately, Geocities does not allow an executable to be downloaded. Please email me to obtain the executable.)

Implementation Methods

Enhencement

• New Classes
  Create class representing rooms, walls, and wall sections. (A wall consists of three wall sections. This is to make it simple to handle a door.)
• OOP
  All game objects are instances of GeomObject class and its derived classes. Common functionalities are implemented in the super clas, GeomObject.


• Representation of the shooter
  Shooter is represented by the gun hole which he is holding. (gun_hole_small.d)
• Representation of the bullet
  Bullet is represented by a ball (better_ball.d)


• When a target (yoda) is shot
  The target turn red, shrinks in half, fall back, and fall down.
• When all targets are down
  All targets will resurrect in the half size so that it would be more difficult to shot.


• View Opition
  User can choose between normal view and far views. There are six far views available: front, back, top, bottom, right, left. The size of the shooter (i.e., the gun hole) is enlarged for the better view. In a far view, all outer walls are removed.
  (At some location, it is not clear where the shooter is located, especially, when the shooter is collided and is not able to move farther. Use the top view to locate the shooter, and try various movement to free the shooter.)
