Battleships meets Minesweeper.

★★★

A game is played on an 8x8 grid of squares. Ten enemy military buildings each occupying one square and are hidden from the player. At the start of the game a UAV may reveal the location of a building. Either the building itself, or an adjacent square horizontally, vertically or diagonally. A player has 50 missiles (turns) to correctly target the ten installations by entering an x and y coordinate to fire at. The state of the board is shown to the player after each missile is launched as follows:

  • ”-“ an unknown square.

  • “H” a building that has been correctly targeted and hit.

  • “x” a miss.

  • “u” a UAV marker.

Missiles

Make

Write a program to play the game, positioning the buildings randomly in the grid.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the subprogram called get_target that:

  1. Prompts the user to enter an x and y target.
  2. Returns a list of the x and y coordinates as integers.

Complete the subprogram called place_buildings that:

  1. Places ten buildings on the board, each occupying one square.
  2. Ensures that two buildings cannot occupy the same square.

Complete the subprogram called uav that:

  1. Scans the inside 7x7 area of the board (i.e. not the outside squares).
  2. If a building exists on that square a “u” is placed either on the square, or the square above, below, left or right randomly.

Complete the subprogram called hit that:

  1. Takes a paramter that is the list of x, y coordinates entered by the player.
  2. If the target square is a hidden building it sets the square to be a “H” (hit).
  3. If the target square is not a hidden building it sets the square to be a “x” (miss).

Complete the subprogram called draw_board that:

  1. Outputs the board to the player.

Complete the subprogram called play_game that:

  1. Calls place_buildings to place the buildings on the game board.
  2. Calls uav to place the uav markers on the game board.
  3. Plays the game until either the player runs out of missiles or the buildings are all hit.
  4. Calls the subprograms get_target and hit to get the player input and handle the result.

Complete the main program so that:

  1. A random seed is chosen.
  2. The board is initialised to be and 8x8 grid of strings.
  3. The subprogram play_game is called.

Typical inputs and outputs from the program would be:

10 military installations sighted. You have 50 cruise missiles to destroy them!
