#★　RGSS3 技能树（设定）　Verα2.00(角色设定型)  by ヒール
#-------------------------------------------------------------------------------
# 一个技能树系统，可以链式学习新技能。
# 通过消耗SP来学习新技能。
#-------------------------------------------------------------------------------
#以下为有关角色SP的脚本：
#$game_variables[x] = $game_actors[角色ID].skill_point (设定x号变量用于存储某
#                                                    角色的SP值)
#$game_actors[角色ID].skill_point += 10（增加某角色10点SP）
#
#你也可以根据队伍id改变角色的SP值：
#
#$game_party.members[队伍id].skill_point
#※队伍id=0 则为队长角色，id=1为队长后第一位角色，2为队长后第二位角色
#
# SceneManager.call(Scene_Skilltree)
# 显示技能树画面
#-------------------------------------------------------------------------------
#Ver1.01 同角色の別技能树の技能の習得が他の技能树の技能の習得を
#可能にしていた不具合を修正しました。
#-------------------------------------------------------------------------------
#Ver2.00　大幅に改修し、自在な形の技能树の作成が可能になりました。
#ただし、以前の设定は流用できません。
#また、習得条件にレベルの设定が出来るようになりました。

设定了10号角色没有技能树

然后进游戏加入10号角色后打开技能树会显示

求助这是因为什么问题……

KB.Driver · 发表于 2019-1-9 23:49:55

脚本正常运行的话，技能树会是数组，数组是有size方法的。
但是你把他的技能树设置成了nil,nil没有size这个方法，就报错了。

你可以试试把nil改成[0]

谢谢帮助，改成[]就不会报错了。

当然，还有一个邪道方法，就是在NilClass中定义size方法

[pre lang="ruby"]class NilClass;def size;0;end;end[/pre]

在这个脚本中这样修改后也能运行，但是毕竟有潜在的隐患。
可以输出一段文字到控制台提醒编程者。
[pre lang="ruby"]
class NilClass
def size
puts "调用了NilClass#size -> 0,此方法存在隐患。如果其他脚本功能异常请检查此处。"
0
end
end
[/pre]
