 作者的话：

就是在地图上显示伤害，没什么特别。
事实上有些偷懒，伤害的相关部分完全是从XP拷贝的。

 教学正文：

在事件里输入脚本：
get_character(事件编号).damage = 伤害数值
get_character(事件编号).critical = true
get_character(事件编号).damage_pop = true

事件编号就是地图上的事件编号，0为本事件，-1为角色，其他则为编号。
伤害数值为负数就是恢复的效果，伤害数值也可以为字符，不一定是数字。
如果不需要CRITICAL的伤害，彩色那行脚本不用写。

可能有些人认为XP默认的不好看，想要用图片显示，所以这里也做了准备。
这个是图片版，从伤害显示美化脚本里踢出来的，图片格式也一样，请自行参考。

还有，要是有人能够拿去优化更好，毕竟是偷懒的产物。
