This game works best in 1.8.9.


UPDATE 08/02/2015
Inspired by a few videos of people playing this game, I've spent a little time this weekend making some revisions. Additionally, since so many people have been having problems with .rar files, it's been compressed as a .zip instead.

Placement:
- Ships now have protection against placements that would leave a ship hanging off the edge of the board (ships can still overlap each other if improperly placed)
- Ships now cannot be accidentally placed in the water (ships are supposed to be placed on the lapis blocks).
- The ship orientation detector has been improved. Multiple players may now be present on each side of the board during setup.

Fanfare:
- I've added a simple title message after a shot is made, announcing either a 'hit' or 'miss' (this can be enabled/disabled from the control room).
- TNT now has some additional particle effects to make the players' shots more visible.

Pieces:
- I've lit up the inside of the hollow ships, which should prevent hostile mobs from spawning inside.

Miscellaneous:
- The board reset has been tweaked and now runs much faster.


This game uses rapid redstone clocks, which can sometimes cause problems for multiplayer servers. This map works best when it is used as a single player world opened to LAN.

Battleship!

Who hasn't played the old stand-by board game, Battleship? Each player gets 5 plastic ships to arrange on a 10x10 grid and then take turns trying to sink their opponent's ships by guessing where they are. last man standing, wins!

This game is meant to be played on peaceful, in creative.

Faithfully recreated in Minecraft, each player starts off by using the teleporter to arrive at their side. Here, they'll find three things:
1) A return teleport to travel to the "Neutral Zone", ala the control center
2) A 10x10 control board to launch missiles at their opponent, and
3) A control board to collect their playing tokens at the game's start, and reset the board at the game's end.

The 10x10 control board will allow each player to launch missiles (TNT) at their opponents board, in hopes of hitting one of their ships.

The second control board will give the player 5 spawn eggs, which will create each of the 5 ships on their playing field:
Aircraft Carrier - 5 spaces long
Battleship - 4 spaces long
Submarine - 3 spaces long
Destroyer - 3 spaces long
Patrol Boat - 2 spaces long

The 6th button resets the entire board, erasing player ships, red and white pegs, and repairing any damage the board may have sustained during play.

Ships are oriented based on the direction the player is facing. The player takes the ship (spawn egg) they would like to place and right-clicks on a lapis lazuli block. The back of the ship will be created at this location, extending forward in the direction the player is facing.

NOTE: There is a small technical limitation to this step of the game. Due to the way the redstone/command block circuitry detects players to orient ships, only one player may be present on each half of the board while the ships are being arranged. If more than one player is present on either half, ships may be placed facing the incorrect direction, or may be duplicated.

Once the ships are arranged, multiple players may be present on either or both halves of the game board. The ships are fully configurable, and can be oriented in any direction.

When a shot is fired on a player's turn (using the control board in the 5th image above), a peg will be placed on the player's board to indicate which space was selected; white indicates a miss, and red indicates a hit.

TNT will be dropped on the opponent's side with each shot; if there is no ship present in that square, it will fall harmlessly into the water and will not damage any adjacent ships. If there is a ship present, it will be damaged.

At the center-side of the board, there is a small room with a handful of controls. Players will not need to access this room normally.
