如何把存档系统变成肉鸽类游戏的风格？

灯笼菜刀王

存档
a = Scene_Save.new
f = File.open("Save1.rxdata", "wb")
a.write_save_data(f)
f.close

读档
if FileTest.exist?("Save1.rxdata")
a = Scene_Load.new
f = File.open("Save1.rxdata", "rb")
a.read_save_data(f)
f.close
$game_system.bgm_play(
$game_system.playing_bgm)
$game_system.bgs_play(
$game_system.playing_bgs)
$game_map.update
$scene = Scene_Map.new
end
