请问如何限定装备某类武器才能使用特定技能？ - Project1

#===============================================================================
# ■ 武器限制技能脚本
#-------------------------------------------------------------------------------
# 使用方法：
# 1. 插入Game_Actor之后，Main之前的任意位置。
# 1. 在下面设置需要被视为武器种类的属性名称。
# 2. 在属性列表内增加相对应的属性
# 3. 利用武器属性来设置种类，每个武器只能归类到一个种类。
# 4. 利用技能属性来设置发动技能需要的武器种类，可以设置多个，但只需满足其中
# 一个便可发动。
# 5. 没有设定条件的技能在任何武器或没有武器的情况下皆可发动。

module WLS
#-----------------------------------------------------------------------------
# 名称列在此的属性会被视为武器种类处理。
# 被视为武器种类的属性将不会对伤害造成任何影响。
