扩展存档数脚本向上翻页时出错

风舞千秋 · 发表于 2011-12-4 21:51:34

我用了扩展存档数的脚本，在存档画面第一页的时候如果按上或左却会报错，这是报错内容

脚本 ‘scene-save’的71行发生NomethodErrer
Undefined method ‘visible’ for nil：NilClass

求教各位高人应该怎么改？搜到以前有人问，却没有解决方式啊……

将60-63行换成
@help_window.dispose
for i in 0..20
   if @savefile_windows[i] != nil
   @savefile_windows[i].dispose
   end
end
就行了不知道现在对你有用不，我刚试出来的

　　关键是你还使用了哪些脚本，是否有冲突？实在不行可以用我这个，可以自定义个数，且与其他脚本冲突较少。第１２行改个数
