本帖最后由 limaolinghu 于 2012-7-9 11:29 编辑实现一个经典的勇者斗恶龙里面，角色队伍都显示在地图上，并且跟随主角移动。我用创建事件和控制事件实现了一个，不知道有没有什么问题，或者有没有更好的方式， ...

我跟你说有脚本哦

   @events[event_index] = Game_Event.new(@map_id, @map.events[event_index])
end

# 在Game_Map的setup_events里面创建5个跟随者，图片这里是随便写的，可以替换为真正的主角行走图

for i in 1...$data_common_events.size
   @common_events = Game_CommonEvent.new(i)
end
  end

在Game_Player里面：
  #--------------------------------------------------------------------------
  # ● 方向键移动处理
  #--------------------------------------------------------------------------
  def move_by_input
return unless movable?
return if $game_map.interpreter.running?

#loop当前地图所有事件，如果存在跟随者，则记录该跟随者的先驱对象
#其中，第一个跟随者的先驱是主角，其他跟随者则跟随前一个跟随者
for i in $game_map.events.keys.sort
   if $game_map.events.event.name == "fellow1"
      @before_move_locations["fellow1"] = self.clone
      fellow1_index = i
   elsif $game_map.events.event.name == "fellow2"
      @before_move_locations["fellow2"] = $game_map.events[fellow1_index].clone
      fellow2_index = i
   elsif $game_map.events.event.name == "fellow3"
      @before_move_locations["fellow3"] = $game_map.events[fellow2_index].clone
      fellow3_index = i
   elsif $game_map.events.event.name == "fellow4"
      @before_move_locations["fellow4"] = $game_map.events[fellow3_index].clone
      fellow4_index = i
   elsif $game_map.events.event.name == "fellow5"
      @before_move_locations["fellow5"] = $game_map.events[fellow4_index].clone
      fellow5_index = i
   end
end

#记录一个是否真正移动过得变量
moved = true
case Input.dir4
when 2;  move_down
when 4;  move_left
when 6;  move_right
when 8;  move_up
else
   moved = false
end

#如果地图事件中有跟随者，并且主角确实移动过，则让跟随者朝着先驱的方向移动
fellows = ["fellow1", "fellow2", "fellow3", "fellow4", "fellow5"]
for event in $game_map.events.values
   if fellows.include?(event.event.name) and moved
      event.follow_preemptor
   end
end
  end

Game_Event里面添加一个简单的函数，来跟随先驱：
  #--------------------------------------------------------------------------
  # ● 跟随前者
  #--------------------------------------------------------------------------
  def follow_preemptor
if @x < $game_player.before_move_locations[@event.name].x
   move_right
elsif @x > $game_player.before_move_locations[@event.name].x
   move_left
elsif @y > $game_player.before_move_locations[@event.name].y
   move_up
elsif @y < $game_player.before_move_locations[@event.name].y
   move_down
end
  end
