Short range scan error in Trk21

An odd Using key … appears every time a short-range scan is performed:

Using key: [8, 4]

  STARDATE:  3600        CONDITION: YELLOW
  QUADRANT: 4 - 8           SECTOR: 2 - 8
    ENERGY:  3000  PHOTON TORPEDOS: 10
  KLINGONS:    23

Logged as issue #2.

This is a simple fix, a debugging statement left at line 38 in Galaxy.groovy needed to be removed.

  final int getAt( final Coords2d keyCoords) {
    assert size()
    assert keyCoords != null && board != null && keyCoords.isValid()
    final ArrayList key = [ keyCoords.first(), keyCoords.last() ]
    // println board.keySet()
    println "Using key: $key"
    board.get key
  }

Weapons fire

It's not much of a war game if you can't shoot the enemy.

Enhancement: Phaser fire

Logged as enhancement issue #3.

Firing a phaser should:

1. Reduce the target's available energy by the hit amount.
2. Remove the target from the game if it's energy <= 0.
3. Inform the user of the weapon's effectiveness.
4. Tell the user they've won the game when the last target is destroyed.

Note: Some of these items may be deferred until torpedo firing is implemented, or moved into their own enhancement.

Enhancement: Torpedo fire

Logged as enhancement issue #4.

Firing a torpedo should:

1. Display a track until either:
   • it hits the target, or
   • it leaves the sector.
2. Remove the target from the game if the torpedo hits it, where a target can be any game object, i.e.
   • An enemy ship.
   • A star base.
   • A star.
3. Tell the user they've won the game when the last target is destroyed.

Note: Some of these items may be implemented as part of issue #3.
