【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

RUBY 代码复制

#--------------------------------------------------------------------------
# ● 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 #

来一个标题界面的脚本。

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

结果出现了好多BUG，这下怎么办了呢？尚请期待第二弹。

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。。

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

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 ...

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
