Game_CharacterBase的类方法是怎么引用的?

b200077

我写了一个让事件移到主角旁边的类方法，可是@mode好像不会+1

脚本

class Game_CharacterBase
attr_reader   :mode                      # ID
alias new_init_public_members init_public_members
def init_public_members
  new_init_public_members
@mode = 0
end
  #--------------------------------------------------------------------------
  # * Move to Designated Position
  #--------------------------------------------------------------------------
#模式1 上下左右
  def mode_cross_out(distance)
  @mode += 1
    @x = $game_player.x
    @y = $game_player.y
  @x += distance if @mode = 3
  @x -= distance   if @mode = 2
@y += distance if @mode = 1
@y -= distance  if @mode = 4
@mode = 0 if @mode = 4
    @real_x = @x
    @real_y = @y
    set_direction(2* @mode)
    @prelock_direction = 0
    straighten
    update_bush_depth
  end
end

= 是赋值，== 是比较相等

1. if @mode == 3
