请问：@encounter_count的值为什么是0？

kvkv97

主角移动中，在类Scene_Map中 P $game_player.encounter_count的值和在Game_Player类中P @encounter_count = rand(n) + rand(n) + 1的值，后者的值永远不等于0，为什么$game_player.encounter_count的值可以等于0？

我为鱼肉

@encounter_count是Game_Player类定义的变量，用途是记录遇敌步数
默认脚本75~80行定义了

#--------------------------------------------------------------------------
  # * Get Encounter Count
  #--------------------------------------------------------------------------
  def encounter_count
    return @encounter_count
  end

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


  # * Get Encounter Count


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


  def encounter_count


    return @encounter_count


  end

也就是可以通过$game_player.encounter_count来访问这个数值。
默认脚本81~90行定义了@encounter_count的赋值方法

RUBY 代码复制

#--------------------------------------------------------------------------
  # * Make Encounter Count
  #--------------------------------------------------------------------------
  def make_encounter_count
    # Image of two dice rolling
    if $game_map.map_id != 0
      n = $game_map.encounter_step
      @encounter_count = rand(n) + rand(n) + 1
    end
  end

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


  # * Make Encounter Count


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


  def make_encounter_count


    # Image of two dice rolling


    if $game_map.map_id != 0


      n = $game_map.encounter_step


      @encounter_count = rand(n) + rand(n) + 1


    end


  end

也就是@encounter_count = @encounter_count = rand(n) + rand(n) + 1  哪怕不算rand随机数，只看 + 1 就可知这个数值绝对不可能在“初始化时赋值为0”

默认脚本update方法定义了@encounter_count的改变。265行左右
也就是每次玩家移动步数减去1，直到减少到0遇敌战斗

# If not moving
    unless moving?
      # If player was moving last time
      if last_moving
        # Event determinant is via touch of same position event
        result = check_event_trigger_here([1,2])
        # If event which started does not exist
        if result == false
          # Disregard if debug mode is ON and ctrl key was pressed
          unless $DEBUG and Input.press?(Input::CTRL)
            # Encounter countdown
            if @encounter_count > 0
              @encounter_count -= 1
            end
          end
        end
      end

# If not moving


    unless moving?


      # If player was moving last time


      if last_moving


        # Event determinant is via touch of same position event


        result = check_event_trigger_here([1,2])


        # If event which started does not exist


        if result == false


          # Disregard if debug mode is ON and ctrl key was pressed


          unless $DEBUG and Input.press?(Input::CTRL)


            # Encounter countdown


            if @encounter_count > 0


              @encounter_count -= 1


            end


          end


        end


      end

Scene_Map update方法定义了遇敌

RUBY 代码复制

# If encounter list isn't empty, and encounter count is 0
    if $game_player.encounter_count == 0 and $game_map.encounter_list != []
      # If event is running or encounter is not forbidden
      unless $game_system.map_interpreter.running? or
             $game_system.encounter_disabled
        # Confirm troop
        n = rand($game_map.encounter_list.size)
        troop_id = $game_map.encounter_list[n]
        # If troop is valid
        if $data_troops[troop_id] != nil
          # Set battle calling flag
          $game_temp.battle_calling = true
          $game_temp.battle_troop_id = troop_id
          $game_temp.battle_can_escape = true
          $game_temp.battle_can_lose = false
          $game_temp.battle_proc = nil
        end
      end
    end

# If encounter list isn't empty, and encounter count is 0


    if $game_player.encounter_count == 0 and $game_map.encounter_list != []


      # If event is running or encounter is not forbidden


      unless $game_system.map_interpreter.running? or


             $game_system.encounter_disabled


        # Confirm troop


        n = rand($game_map.encounter_list.size)


        troop_id = $game_map.encounter_list[n]


        # If troop is valid


        if $data_troops[troop_id] != nil


          # Set battle calling flag


          $game_temp.battle_calling = true


          $game_temp.battle_troop_id = troop_id


          $game_temp.battle_can_escape = true


          $game_temp.battle_can_lose = false


          $game_temp.battle_proc = nil


        end


      end


    end

也就是当这个数值为0，并且设置了敌群，那么就随机一个敌群战斗。

另外，每次地图改变，进入战斗都会重新刷新步数

视频教程那么多，建议好好看看视频教学。很快就学会这些简单的了

不明白你想问什么
@encounter_count = rand(n) + rand(n) + 1
生成遇敌计数，n是地图遇敌步数，默认是30，所以这个值肯定不可能是0
角色每次移动这个值减少，直到等于0遇敌战斗（如果设置了敌队）
$game_player.encounter_count和你说的@encounter_count是一回事。
它是0就战斗，凭什么不让人家等于0。。

有高手指点一下在下的疑惑吗？

$game_player的encounter_count有被减少的地方，调用@encounter_count = rand(n) + rand(n) + 1这段的方法好像是每次进入地图的时候被调用一次，所以并不是永远不等于0的
