how enemy targeting works?

I tried to look it up in the script editor but I don't understand it, lol, so I need some explaining on these topics... - how enemy choose its target? - how random target skills work? - how is tgr related to all of it?

This is the piece of code that determine the random target from Game_Unit

Code:

  def random_target
    tgr_rand = rand * tgr_sum
    alive_members.each do |member|
      tgr_rand -= member.tgr
      return member if tgr_rand < 0
    end
    alive_members[0]
  end

The target selection will be something like roulette wheel selection, where the highest tgr value battler will have a chance to be targeted more. Here are the breakdowns:

rand = will generate a number between 0 to 1. The generated number will be something like 0.234, 0.563, 0.876, etc
tgr_sum = sum of tgr of all battle members
tgr_rand = rand * tgr_sum means, it's like selecting a random selection point. Where the value will be ranged from 0 to tgr_sum
next: the code will iterate all "alive_battlers" one by one. Each iteration will reduce tgr_rand value by current iterated battler's tgr value. If the value reached 0, the current iterated battler will be the one is targeted. Otherwise, it will be the battler in index 0
