#  INTRODUCTION:

#

#  This script allows one  to make the HP and SP scores of enemies variable.

#  That is to say,  any enemy defined within the hash arrays provided,  will

#  have randomly generated hit and/or skill points rather than those defined

#  in the database.

#

#  There are two methods which may be employed to generate these scores, the

#  basic 'Ranged Score' approach and the 'Dice-Rolling' method. Both methods

#  involve randomly generated values, but there are certain differences.

#

#  The random value generated by the Ranged method is a single numeric score

#  that has as much an equal shot across the board.  For an example,  assume

#  that an enemy's HP  would be based on a range of 1 to 50.   The chance of

#  the enemy having  an HP of 1 is just as likely  as the enemy having 50 as

#  its HP score.

#

#  As to the random value  generated by the Dice-Rolling method,  it assumes

#  that multiple random values  of equal range are being generated and added

#  together to form  a final value.  This creates a basic range  between the

#  lowest possible result of all values generated (or rolled) to the highest

#  number possible.   However, it also supports the notion of a mean average

#  score with the 'rolled' values.  A classic example of this is familiar to

#  those whom play  "Dungeons & Dragons"  when rolling three six-sided dice.

#  The range of the score would hover between 3 to 18.  But the mean average

#  for the dice hovers between 8 to 12,  a general bell-curve created by the

#  possible random rolls.  Ergo,  the Dice-Rolling method may deliver a more

#  controlled output.

#

#  In both cases,  a fixed value may be added to the score under the assump-

#  tion that the HP and/or SP cannot below a certain value.

#

#------------------------------------------------------------------------------

#

#  NOTE:

#

#  The bulk of this was done last night. Do note that as a system, it may be

#  adapted to include a separate MP (or like) category for systems that have

#  such enemy stats.  But I cannot guide  how to introduce other than recom-

#  mending that one study this script.

#

#------------------------------------------------------------------------------

#

#  COMPATABILITY:

#

#  Designed for the RPGMaker XP environment. No methods were overwritten, so

#  it should work with most any system  that does not adversely alter either

#  methods enemies generate their hp or sp scores.
