灾难修改

本页面讲述的内容长期有效。
（重定向自Disaster modding）

灾难是EU4在1.9版本引入的全新系统，用于取代之前用于模拟国家灾难的MTTH事件。

灾难文件

首先要在 /Europa Universalis IV/common/disasters下创建一个新文件。这里以发生在新世界的瘟疫举例：

第一行写上灾难名称： 

influenza_epidemic = {
}

其他内容都在这个大括号内进行描述。

接下来是对其潜在条件的描述。注意，这只是决定它是否会显示在玩家的“稳定与扩张”界面中（图标仍然是灰色），而非令其进度增加的条件。这里的编写同决议与事件基本一致。 

potential = {
        NOT = {
                has_country_flag = had_influenza_epidemic
        }
        OR = {
                technology_group = north_american
                technology_group = mesoamerican
                technology_group = andean
                technology_group = south_american
        }
        any_country = {
                technology_group = western
                has_discovered = ROOT
        }
}

本例中，灾难的潜在条件即是：本国未发生过此灾难、新世界科技组、有西方科技组的国家发现本国。

接下来定义在满足潜在条件后，什么条件可以开启本灾难。满足本条件，并且进度实际增长时，就会在用户界面中弹出红色的警告旗帜。 

can_start = {
        has_any_disaster = no
        is_year = 1500
}

1.10后，你可以定义什么时候本灾难的进程会中止。本例中，如果本国爆发另一个灾难时，本灾难的进度就会停止。 

can_stop = {
        has_any_disaster = yes
}

接下来定义让灾难进度月度增加的条件： 

progress = {
        modifier = {
                factor = 1
                any_country = {
                        technology_group = western
                        has_discovered = ROOT
                }
        }
        modifier = {
                factor = 2
                any_neighbor_country = {
                        technology_group = western
                }
        }
        modifier = {
                factor = 1
                any_neighbor_country = {
                        OR = {
                                has_country_flag = had_influenza_epidemic
                                has_disaster = influenza_epidemic
                        }
                }
        }
}

这里，如果有西方科技组的国家发现本国，那么它的进度每月+1，如果它与本国相邻，额外+2，如果本国与发生过瘟疫，或者正在发生瘟疫的国家接壤，也会额外+1。

接下来定义让已经爆发的灾难结束的条件： 

can_end = {
        had_country_flag = { flag = flu_epidemic days = 3650 }
        stability = 2
}

本例中，这个国家必须要拥有某个事件flag10年，且稳定度为+2，灾难才可能结束。

这里定义灾难为国家提供的修正： 

modifier = {
        global_unrest = 3
        stability_cost_modifier = 0.5
}

然后定义灾难开启时的事件（一般有一个直接的负面效果，以及一个flag的设定，用于判断何时结束），和结束时的事件（一般给一个正面效果，同时如果不希望它再度发生的话，也要给一个flag用作标记）。 

on_start = epidemic.1
on_end = epidemic.2

这里，epidimic.1中给的flag就是flu_epidemic，epidimic.2中的是had_influenza_epidemic。

1.26后，你可以定义灾难开启时的效果。在本例中，附加了一段文本custom_tooltip。 

on_start_effect = {
     custom_tooltip = epidemic_tooltip
}

最后决定月度事件的发生： 

on_monthly = {
        events = {
        }
        random_events = { 
                1000 = 0
                100 = epidemic.3
                100 = epidemic.4	
        }
}

"events" 中的事件会在每月周期中都会触发，而"random_events"中的随机事件何时触发，取决于列表中给每个事件的权重：这里，有5/6的概率不发生事件，发生两个事件的概率各为1/12。 0

本地化

你需要对灾难的名称和描述本地化，也不要忘记相关事件。 

influenza_epidemic: "瘟疫爆发"
desc_influenza_epidemic: "本国正在遭受白皮恶魔从海洋另一边带来的可怕瘟疫。"

图标


灾难图标的位置在/Europa Universalis IV/gfx/interface/disasters。一个图标文件内要做三个版本的图标：进度增长时的彩色标志、爆发后，带有火光的标志，以及潜在灾难的灰色标志。

最后在/Europa Universalis IV/interface/countrystabilityview.gfx添加如下文字（使用np++打开），以让你的图标出现在稳定与扩张界面中。 

spriteType = {
 name = "GFX_disaster_influenza_epidemic"
 texturefile = "gfx//interface//disasters//influenza_epidemic.dds"
 noOfFrames = 3
 loadType = "INGAME"
}

现在，你已经完成了灾难的制作。
