脚本中出现nil值问题

浮云桑 · 发表于 2012-7-5 19:42:44

最近修改一个模板中发现没办法把转移到目标工程里面
常常出现以下的问题

members.size
members.level
这些为空（nil）

此外还有就是无法取得
@total_sec的值

我试着将
@total_sec = header[:playtime] #header[:playtime]=$game_system.playtime
改为
@total_sec = $game_system.playtime

模板是外站的。（我用一个空的工程也无法复制- -蛋疼了，求指教了）

补充- -我直接将代码原封不动复制过去都是没用。难道是dll文件的问题？

队伍中没有人物。。

为什么说修改了很久~因为单独那个语句通过修改变量是没有问题的。
我就纳闷了，为什么前面明明声明了，后面无法引用。
最奇怪的还是@total_sec压根就无法得到 playtime的数据
不过我将dll换了一下就能用了~
