#==============================================================================
# 物品备注<load N> 则该物品占用 N 点负重
# load也可以写成「负重」或「負重」#注：没有“「」”
# 不写的话默认为 Default_Load
# 更改当前负重可以对 $game_party.current_load 进行加，减，赋值
# 例如：$game_party.current_load += 1 #当前物品总重量加 1
# 默认给物品增加一行说明.说明内容是物品的重量. 但默认帮助窗口一共只能显示2行内容.
# 因此你在设置帮助说明的时候. 如果设置了2行内容. 那么这新增加的第3行将无法显示出来.

  # 当有新队员加入队伍并且也带有负重的装备那么你也需要为当前负重加上对应的重量，
  # 例如：$game_party.current_load += 10 就是加上10的当前负重
