我又遇到问题了……跪求各位大神，请问为啥一在技能界面按A就会弹出错误undefined method 'manual_lvup?' for nil:NilClass 跪谢！

遇到这类的问题，至少应当将你的范例工程上传上来，否则我们是没法分析的。
至于出现这个错误，应该是对一个本应该成为一个新class的变量赋值了null，在调用manual_lvup?方法时发生错误。
你可以尝试把技能界面的脚本复制到记事本里，搜索引号里面的内容：“.manual_lvup?”然后自己解决。
也可以找Input.trigger?(:X) 或Input.press?(:X)，找到调用A键的部分，然后解决。
由于我看不到你的工程，只能帮你到这里了
