【VA新手向】坏男子教你简单粗暴地改脚本第一弹

坏男子

首先，新人报道下下，我叫坏男子。
大家都知道有一个LOGO脚本，如下就是[pre lang="ruby" line="01"]#--------------------------------------------------------------------------
# ● 显示图片
#-------------------------------------------------------------------------
filename = "Graphics/Pictures/Logo" # 图片文件名
time0 = 60 # 渐显所需时间（单位：帧）
time1 = 120 # 渐显完毕后等待时间（单位：帧）
time2 = 60 # 渐隐所需时间（单位：帧）
time3 = 60 # 渐隐完毕后等待时间（单位：帧）
@show_logo = Sprite.new
@show_logo.opacity = 0
@show_logo.bitmap = Bitmap.new(filename)
v0 = 255 / time0
v2 = 255 / time2
for i in 1..time0 #渐显
@show_logo.opacity = i * v0
Graphics.update
end
@show_logo.opacity = 255
Graphics.wait time1 # 等待
for i in 1..time2 #渐隐
@show_logo.opacity = 255 - i * v2
Graphics.update
end
@show_logo.dispose
Graphics.wait time3 #[/pre]来一个标题界面的脚本。[pre lang="ruby" line="01"]#encoding:utf-8
#==============================================================================
# ■ Scene_Title
#------------------------------------------------------------------------------
# 　标题画面
#==============================================================================

class Scene_Title < Scene_Base
  #--------------------------------------------------------------------------
  # ● 开始处理
  #--------------------------------------------------------------------------
  def start
    super
    SceneManager.clear
    Graphics.freeze
    create_background
    create_foreground
    create_command_window
    play_title_music
  end
  #--------------------------------------------------------------------------
  # ● 获取渐变速度
  #--------------------------------------------------------------------------
  def transition_speed
    return 20
  end
  #--------------------------------------------------------------------------
  # ● 结束处理
  #--------------------------------------------------------------------------
  def terminate
    super
    SceneManager.snapshot_for_background
    dispose_background
    dispose_foreground
  end
  #--------------------------------------------------------------------------
  # ● 生成背景
  #--------------------------------------------------------------------------
  def create_background
    @sprite1 = Sprite.new
    @sprite1.bitmap = Cache.title1($data_system.title1_name)
    @sprite2 = Sprite.new
    @sprite2.bitmap = Cache.title2($data_system.title2_name)
    center_sprite(@sprite1)
    center_sprite(@sprite2)
  end
  #--------------------------------------------------------------------------
  # ● 生成前景
  #--------------------------------------------------------------------------
  def create_foreground
    @foreground_sprite = Sprite.new
    @foreground_sprite.bitmap = Bitmap.new(Graphics.width, Graphics.height)
    @foreground_sprite.z = 100
    draw_game_title if $data_system.opt_draw_title
  end
  #--------------------------------------------------------------------------
  # ● 绘制游戏标题
  #--------------------------------------------------------------------------
  def draw_game_title
    @foreground_sprite.bitmap.font.size = 48
    rect = Rect.new(0, 0, Graphics.width, Graphics.height / 2)
    @foreground_sprite.bitmap.draw_text(rect, $data_system.game_title, 1)
  end
  #--------------------------------------------------------------------------
  # ● 释放背景
  #--------------------------------------------------------------------------
  def dispose_background
    @sprite1.bitmap.dispose
    @sprite1.dispose
    @sprite2.bitmap.dispose
    @sprite2.dispose
  end
  #--------------------------------------------------------------------------
  # ● 释放前景
  #--------------------------------------------------------------------------
  def dispose_foreground
    @foreground_sprite.bitmap.dispose
    @foreground_sprite.dispose
  end
  #--------------------------------------------------------------------------
  # ● 执行精灵居中
  #--------------------------------------------------------------------------
  def center_sprite(sprite)
    sprite.ox = sprite.bitmap.width / 2
    sprite.oy = sprite.bitmap.height / 2
    sprite.x = Graphics.width / 2
    sprite.y = Graphics.height / 2
  end
  #--------------------------------------------------------------------------
  # ● 生成指令窗口
  #--------------------------------------------------------------------------
  def create_command_window
    @command_window = Window_TitleCommand.new
    @command_window.set_handler(:new_game, method(:command_new_game))
    @command_window.set_handler(:continue, method(:command_continue))
    @command_window.set_handler(:shutdown, method(:command_shutdown))
  end
  #--------------------------------------------------------------------------
  # ● 关闭指令窗口
  #--------------------------------------------------------------------------
  def close_command_window
    @command_window.close
    update until @command_window.close?
  end
  #--------------------------------------------------------------------------
  # ● 指令“开始游戏”
  #--------------------------------------------------------------------------
  def command_new_game
    DataManager.setup_new_game
    close_command_window
    fadeout_all
    $game_map.autoplay
    SceneManager.goto(Scene_Map)
  end
  #--------------------------------------------------------------------------
  # ● 指令“继续游戏”
  #--------------------------------------------------------------------------
  def command_continue
    close_command_window
    SceneManager.call(Scene_Load)
  end
  #--------------------------------------------------------------------------
  # ● 指令“退出游戏”
  #--------------------------------------------------------------------------
  def command_shutdown
    close_command_window
    fadeout_all
    SceneManager.exit
  end
  #--------------------------------------------------------------------------
  # ● 播放标题画面音乐
  #--------------------------------------------------------------------------
  def play_title_music
    $data_system.title_bgm.play
    RPG::BGS.stop
    RPG::ME.stop
  end
end[/pre]那么问题来了，能不能使用LOGO脚本把标题改为LOGO的效果呢？我们直接把LOGO脚本放在标题界面的脚本的start函数的end的前面，如下[pre lang="ruby" line="01"]#encoding:utf-8
#==============================================================================
# ■ Scene_Title
#------------------------------------------------------------------------------
# 　标题画面
#==============================================================================

    SceneManager.clear
    Graphics.freeze
    create_background
    create_foreground
    create_command_window
    play_title_music
    filename = "Graphics/Pictures/Logo" # 图片文件名
    time0 = 60 # 渐显所需时间（单位：帧）
    time1 = 120 # 渐显完毕后等待时间（单位：帧）
    time2 = 60 # 渐隐所需时间（单位：帧）
    time3 = 60 # 渐隐完毕后等待时间（单位：帧）
    @show_logo = Sprite.new
    @show_logo.opacity = 0
    @show_logo.bitmap = Bitmap.new(filename)
    v0 = 255 / time0
    v2 = 255 / time2
    for i in 1..time0 #渐显
       @show_logo.opacity = i * v0
       Graphics.update
    end
    @show_logo.opacity = 255
    Graphics.wait time1 # 等待
    for i in 1..time2 #渐隐
       @show_logo.opacity = 255 - i * v2
       Graphics.update
    end
    @show_logo.dispose
    Graphics.wait time3
  end
  #--------------------------------------------------------------------------
  # ● 获取渐变速度

  def transition_speed

  end
  #--------------------------------------------------------------------------

end[/pre]结果出现了好多BUG，这下怎么办了呢？尚请期待第二弹。

logo脚本本身不就是在标题显示的么…………为什么还要多次一举再扔进标题界面里……

扔就扔吧……但是正常来说不都是扔到方法最开始的么……扔到最后不出bug反而不科学…………

最后吐槽这个logo脚本的缩进，以及 @show_logo.bitmap 没有释放

1. def m51552logo
   
2.   sprite = Sprite.new
   
3.   sprite.opacity = 0
   
4.   sprite.bitmap = Cache.picture("logo")
   
5.   while sprite.opacity != 255
   
6.     sprite.opacity += 8
   
7.     Graphics.update
   
8.   end
   
9.   loop do
   
10.     Input.update
    
11.     break if Input.trigger?(:C)
    
12.   end
    
13.   while sprite.opacity != 0
    
14.     sprite.opacity-=8
    
15.     Graphics.update
    
16.   end
    
17.   sprite.bitmap.dispose
    
18.   sprite.dispose
    
19. end
    
20. m51552logo

在37行，精灵的透明度是255-i乘以v2，i乘以v2达到255的时候，精灵的透明度为0了

……这和只释放sprite没释放bitmap有什么关系么

gonglinyuan

想你这样写脚本，游戏玩了一两个小时就爆内存了吧。。

虽然看起来效果是正确的，但是bitmap还占用了内存空间没有被释放啊。

学脚本是绝对不能“简单粗暴”的，尤其是应用广泛的外挂脚本，每个功能的实现都要精准细致才好

不然BUG的累积是十分恐怖的

不知道第二弹会怎么样。。要一直这样下去不知有多少新手会被误导。。
