在地图上建一事件，用脚本：
a=[2,3]
$scene=\
Mercenaries::\
Scene_Mercenaries.new(a)
我在#●●●●@window_mercenaries=Mercenaries::Window_Mercenaries.new(@mercenaries)
里面参数传递了上面的参数，为什么下面的@mercenaries的值是nil?应该如何改？

开始新游戏就会 设置初期角色 ， 但是这里
Mercenaries::Window_Mercenaries.new(@mercenaries) 不但直接进入场景，
而且@mercenaries根本没有赋值，
而地图那个根本读不到... ...
其它地方的调用也没有考虑 $game_party.actors_1 或者  @mercenaries 是 空/nil 的情况，
会频繁报错，改一改吧... ...

因为不同类的变量默认是受保护，无法读写的，
@mercenaries 只在它的相关窗口/场景使用，
所以想用还得 attr_reader 或者 attr_accessor
