Using Hashes?

[MasterMind]

Yes it's me again. I'm trying to use hashes to apply certain numbers to certain enemies. For example, let's say I have a variable called points. I would like this variable to increase by 3 for every ghost defeated, but 10 for every goblin, and 15 for every daemon. And if an enemy isn't defined with a certain value, how would I go about setting a default?

Would it be like this?

POINTS = {enemy.id => amount, enemy.id => amount}

The hash syntax is correct.  To ensure a default value in case a value doesn't exist in the hash, you would use code like:

point = POINTS[enemyID] || 0

where the value would be 0 if "enemyID" isn't defined in the hash.

Ok. So how would I go about implementing this? I have my code below:

#==============================================================================
# ** Scene_Battle (part 2)
#------------------------------------------------------------------------------
#  This class performs battle screen processing.
#==============================================================================

class Scene_Battle
  #--------------------------------------------------------------------------
  # * Alias Listings
  #--------------------------------------------------------------------------  
  alias mvment_start_phase5 start_phase5
  #--------------------------------------------------------------------------
  # * Start After Battle Phase
  #--------------------------------------------------------------------------  
  def start_phase5
    $movement_points += 1
    mvment_start_phase5
  end
end

EDIT: Crap, hit the post button instead of preview. Anyways, I want to change it so it checks to see if the enemy.id is defined, and if not, then the default is used.

You can do like this:

class Scene_Battle
  alias mvment_start_phase5 start_phase5
  def start_phase5
    $movement_points += 1
    for enemy in $game_troop.enemies
      if !enemy.hidden
        if POINTS.has_key?(enemy.id)
          your_variable += POINTS[enemy.id]
        end
      end
    end
    mvment_start_phase5
  end
end

I don't know which variable you want to increase, so replace "your_variable" with yours.

In case it is the "$movement_points" variable you showed there, just do:

class Scene_Battle
  alias mvment_start_phase5 start_phase5
  def start_phase5
    for enemy in $game_troop.enemies
      if !enemy.hidden
        if POINTS.has_key?(enemy.id)
          $movement_points += POINTS[enemy.id]
        end
      end
    end
    mvment_start_phase5
  end
end

The code just includes a loop for every enemy in the battle, it excludes the hidden ones, and if the enemy.id is defined in your POINTS hash, it is added to your variable.

PD: I haven't tested it, but it should work.

Works like a charm. Thanks guys.

Alternatively you can specify a default value if you don't want to include a check.

POINTS.default = 0

In that case any key that isn't found in the Hash will retrieve the value 0.
