如图，脚本小白，请问大大们如何解决 undefined method"xxx" for nil:Nilclass 这样的问题？遇到过好多次了{:2_270:}

请贴上脚本并用代码功能包含。
undefined method可能是脚本本身的bug也可能是脚本冲突引起的。前者没办法弄（除非……知道脚本思路+RGSS2），后者则可删除一些脚本来解决问题

原帖里提供的范例下来运行正常，但是拷了他的系统图和脚本后到自己的作品后一开始游戏就弹出那个提示，不知缺漏了什么步骤T_T

直接粘贴？

怪蜀黍 · 发表于 2012-11-16 19:01:43

运行无错，估计是和你的脚本不兼容。看来需要你上工程了。

汗，看来是脚本冲突，换成Beside大大那个好了= =
