Barrier Skills

[Fomar0153]

With these you can create a barrier which protects you from physical attacks or a barrier that protects enemies from physical attacks.

First the script:

class Game_Battler
  
  attr_accessor :barrier
  
  alias barrier_initialize initialize
  def initialize
    barrier_initialize
    @barrier = 0
  end
  
  alias skill_effects skill_effect
  def skill_effect(user, skill)
    if skill.id == 1
      self.barrier = self.int
      return true
    end
    
    return skill_effects(user, skill)
  end
  
end


class Scene_Battle
  
  alias barrier_start_phase5 start_phase5
  def start_phase5
    for actor in $game_party.actors
      actor.barrier = 0
    end
    
    
    barrier_start_phase5
  end
  
end

And if you have a default attack_effect:

class Game_Battler
  
    def attack_effect(attacker)
    # Clear critical flag
    self.critical = false
    # First hit detection
    hit_result = (rand(100) < attacker.hit)
    # If hit occurs
    if hit_result == true
      # Calculate basic damage
      atk = [attacker.atk - self.pdef / 2, 0].max
      self.damage = atk * (20 + attacker.str) / 20
      # Element correction
      self.damage *= elements_correct(attacker.element_set)
      self.damage /= 100
      # If damage value is strictly positive
      if self.damage > 0
        # Critical correction
        if rand(100) < 4 * attacker.dex / self.agi
          self.damage *= 2
          self.critical = true
        end
        # Guard correction
        if self.guarding?
          self.damage /= 2
        end
      end
      # Dispersion
      if self.damage.abs > 0
        amp = [self.damage.abs * 15 / 100, 1].max
        self.damage += rand(amp+1) + rand(amp+1) - amp
      end
      # Second hit detection
      eva = 8 * self.agi / attacker.dex + self.eva
      hit = self.damage < 0 ? 100 : 100 - eva
      hit = self.cant_evade? ? 100 : hit
      hit_result = (rand(100) < hit)
    end
    # If hit occurs
    if hit_result == true
      # State Removed by Shock
      remove_states_shock
      
      
      # MODIFIED
      # was originally
      # Substract damage from HP
      #self.hp -= self.damage
      
      if self.barrier == 0
        self.hp -= self.damage
      else
        self.barrier -= self.damage
        if self.barrier < 0
          self.barrier = 0
          self.damage *= 3
          self.hp -= self.damage
        else
          self.damage = '[' + self.damage.to_s + ']'
        end
      end
      
      #END OF MODIFIED
      
      # State change
      @state_changed = false
      states_plus(attacker.plus_state_set)
      states_minus(attacker.minus_state_set)
    # When missing
    else
      # Set damage to "Miss"
      self.damage = "Miss"
      # Clear critical flag
      self.critical = false
    end
    # End Method
    return true
  end
  
end

Otherwise merge it.

In the example:

  def skill_effect(user, skill)
    if skill.id == 1
      self.barrier = self.int
      return true
    end
    
    return skill_effects(user, skill)
  end

When using heal instead of regaining hit points it will now create a barrier with the character's int as it's strength and physical attacks will damage the barrier rather than the character, however to prevent people avoiding any damage, when the barrier breaks if there is any extra damage the character will feel the full attack x3.
If you need any help with coming up with differant barrier strength algorithms then ask.
eg: Twice the user's int
self.barrier = user.int * 2
