决议修改

决议路径

决议位于/Hearts of Iron IV/common/decisions，决议组路径位于 /Hearts of Iron IV/common/decisions/categories。

创建决议组

所有的决议都需要进入可以容纳多个决议的决议组中，并且决议组可以拥有自己的图片和描述。一个基本的决议组如下所示。在这一页中，我们会使用寻找资源的决议组创建作为例子。想要创建决议组，你首先需要在decisions/categories文件夹下创建一个文件，可以是 00_decision_categories.txt或是其他文件。 决议组条目如下所示：

find_resources = {
     icon = generic_prospect_for_resources
}

这是最简单的一种决议组，并且无论何种情况下都会出现。 You can also add conditions such as allowed, available, and visible like in normal decisions if you want the category to appear under specific circumstances. 例如：

find_resources = {
     icon = generic_prospect_for_resources
     available = { 
          num_of_civilian_factories > 3
     }
}

这将使得决议组仅在你拥有多于三个民用工厂时才会出现，与决议组中的决议是否满足条件无关。

创建决议

决议需要位于决议组中——让我们拿上之前的寻找资源决议组，并加入一个给国家增加乡村基础设施的决议。

find_resources = {
     develop_infrastructure = {
     
     }
}

决议效果

决议效果的代码是complete_effect。这条语句位于决议中，决定了当决议被选中时会发生的事情。让我们添加一个在选中时以500人力的代价增加基础设施的效果：

find_resources = {
     develop_infrastructure = {
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }
      }
}

如果想更进一步了解random_owned_state，请查阅作用域，如果想了解关于add_building_construction和add_manpower的更多信息，请查阅指令。

随机效果(random_list effects)

默认情况下，决议启用时每次都是用相同的随机种子。这意味着，如果random_list用在决议中，它每次产生的结果都是相同的。 为了避免这种情况发生，你可以在决议代码中添加fixed_random_seed = no。 例如：

decision_category = {
	give_pp_or_experience_decision = {
		icon = generic_research
		available = {
			has_war = yes
		}
		fixed_random_seed = no
		complete_effect = {
			random_list = {
				33 = {
					add_political_power = 10
				}
				33 = {
					army_experience = 10
				}
				33 = {
					air_experience = 10
				}
			}
		}
		ai_will_do = {
			factor = 0
		}
	}
}

决议可用性

你可能想让某些决议在只满足某些条件的情况下才可用。例如，我们的发展基础设施的决议应当只能在国家有多于500人力的时候才可用。这可以用available语句实现，例子如下：

find_resources = {
     develop_infrastructure = {
          available = {
               has_manpower > 500
          }
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }
     }
}

如果想要进一步了解has_manpower和其他条件，参见条件。

决议花费

你可能也想让你的决议需要花政治点数启用。让我们给这个决议增加50政治点数的花费：

find_resources = {
     develop_infrastructure = {
          cost = 50
          available = {
               has_manpower > 500
          }
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }
     }
}

决议是否可见

决议可能不总是要在决议栏中出现，否则会有些杂乱。为了做到这一点，我们只想让玩家拥有多于0的人力的时候才能看到这个决议，如下所示：

find_resources = {
     develop_infrastructure = {
          visible = {
               has_manpower > 0
          }
          cost = 50
          available = {
               has_manpower > 500
          }
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }
     }
}

等一会再消失，或者过一会再回来

你可能想让决议在完成后等一会再消失，或者你想让决议在完成后过一会再度出现，又或者你可能只想让这个决议使用一次，这些可以通过如下方式实现：

days_remove = 5 # 完成后维持5天再移除

days_re_enable = 5 # 将在5天后显示于界面中，可以再次选择

fire_only_once = yes #在移除后将不会重新出现

导致战争的决议

如果你的决议会导致一个国家对另一个国家宣战，下列语句都会告知将被宣战的国家一场战争即将到来，同时警告AI把部队移动到边界上：

war_with_on_remove = TAG # War is declared on the nation in the TAG when the decision is removed

war_with_on_complete = TAG # War is declared on the nation in the TAG when the decision is completed

war_with_on_timeout = TAG # War is declared on the nation in the TAG when the decision times out

war_with_target_on_remove = yes # War is declared when the targeted decision is removed

war_with_target_on_complete = yes # War is declared when the targeted decision is completed

war_with_target_on_timeout = yes # War is declared when the targeted decision times out

移除时的效果

在一个决议执行完毕后（即你设置的决议的天数），你可能希望发生一个效果。以我们的基础设施决议为例，我们想在10天后归还人力：

find_resources = {
     develop_infrastructure = {
          visible = {
               has_manpower > 0
          }
          cost = 50
          available = {
               has_manpower > 500
          }
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }  
          days_remove = 10
          remove_effect = {
               add_manpower = 500
          }
     }
}

决议修正

使用决议，你可以让一个修正只在一定时间内发挥作用。使用修正，只要决议处于激活状态（使用day_remove语句设置），就可以做到这一点。我们现在的决议已经有点忙了，所以这里建立一个新的决议，在激活后的200天内增加10%的战略资源获取率，代价是花费100政治点数。该决议只能使用一次：

find_resources = {
     resource_spree = {
          cost = 100
          fire_only_once = yes
          modifier = {
               local_resources_factor = 0.1
          }
          days_remove = 200
     }
}

关于local_resources_factor的更多信息，参见修正

目标决议

有时你希望一个决议针对多个TAG - 与其多次编写相同的决议来针对每个国家，不如使用一个有针对性的决议。在有针对性的决议中，FROM指的是（令人困惑的）决议的目标，而不是使用者。这里有一个新的决议，给予一个国家在随机状态下对德国、美国和日本其中之一增加基础设施的能力，代价是FROM（所得国）要付出50的政治点数和500的人力。

find_resources = {
     help_others = {
          target_trigger = {
               FROM = {
                    OR = {
                         tag = GER
                         tag = USA
                         tag = JAP
                    }
               }
          }
          cost = 50
          fire_only_once = yes
          complete_effect = {
               FROM = {
                    random_owned_state = {
                         add_building_construction = { type = infrastructure level = 2 instant_build = yes }
                    }
                }
                add_manpower = -500
          }
     }
}

State targeted decisions

The following section is duplicated from a blogpost by Yard1.

State targeted decisions are very similar to country targeted decisions. In order to define a decision as a state targeted decision, you need to put:

   state_target = yes

Then FROM will be a state scope, with target_trigger and target_root_trigger working like with country targeted decisions.

Just like with country targeted decisions, you can define targets (State IDs or variables) and /Hearts of Iron IV/target_array. Useful target arrays include:

   core_states
   controlled_states
   owned_states

Each array can be prefixed with another scope (so eg. EQS.core_states will scope to EQS’s core states, even if ROOT is something else), and you can use your own arrays too.

One extra key state targeted decisions have is on_map_mode. It has two possible values:

   on_map_mode = map_only - will not show the decisions in the decision tab, and instead only put icons over the states in the 3d map
   on_map_mode = map_and_decisions_view - will show the decisions both on map and in the decision tab

Another key is highlight_color_while_active = 1 - seems to highlight the state as long as the decision is active, even after exiting the decision tab. Only used for missions in vanilla.

Activating targeted decisions

Since target_trigger is checked for every country it can have quite a heavy effect on performance. If you simply want to add a targeted decision against a specific country from a focus you can do it by using an effect.

activate_targeted_decision = { target = TAG decision = decision_to_activate }

Note: FROM can be used here in place of a tag

Notes on testing

Target triggers may not be evaluated immediately. When testing triggers, give the game some time to reprocess / evaluate it, rather than erroneously assuming a coding error right away. This explicitly includes after unlocking the visible/available triggers through another action (decision made, national focus completed, etc.).

任务

任务遵循与决议相同的基本原则。这些任务也位于一个类别中 - 对于任务，我们将建立一个新的决议组和一个新的任务，这次是关于波兰征服柏林的。下面是我们在一个决议组中的完整任务 - 如果你不明白，也不用担心，我们会把它逐个分解以讲解：

polish_conquest = {                               # 这是我们的决议组
     conquer_berlin = {                           # 这是我们的任务id
          allowed = { tag = POL }                 # 这项任务只允许在波兰进行。其他国家将无法看到它或激活它
          available = {                           # 这里的Available和goal中的一样，因为:
               controls_state = 64                      # 只有控制了64号省份（柏林），我们才能完成这个任务
          }
          activation = {                          # 在这种情况下，任务被激活并开始倒计时：
               has_war_with = GER                       # 与德国交战
          }
          is_good = yes                           # 这个任务的颜色编码是有益事情（非危机）
          selectable_mission = yes                # 这个任务将在玩家点选任务时完成，而非自动完成
          days_mission_timeout = 100              # 距离任务失败前有多少天？
          timeout_effect = {                      # 当任务失败时会发生什么？
               add_political_power = -50               # 失去50点政治点数
          }
          complete_effect = {                    # 当我们激活任务时，即任务成功时会发生什么？
               add_political_power = 50                # 获得50点政治点数
          }
     }
}

决议组、决议及任务的本地化

主条目：Localisation

决议组和决议都是以类似于国策树的方式进行本地化。为了使我们的决议组和决议本地化，我们将有一个这样的本地化文件：

find_resources:0 "Find Resources"
find_resources_desc:0 "To increase the military might of our nation, we must find more natural resources within our borders to exploit"

develop_infrastructure:0 "Develop Infrastructure"
develop_infrastructure_desc:0 "In order to access our natural resources more effectively, we must develop rural infrastructure!"

resource_spree:0 "Resource Spree"
resource_spree_desc:0 "We should go on a resource spree to increase production for a short time"

警告：决议组的描述是强制存在的；在本地化文件中缺少"_desc "条目将导致所有其他决议组完全不显示。

Localising targeted decisions

We can use From to localise for our targeted country in targeted decisions, for example:

help_others:0 "Help [From.GetName] with their infrastructure"
help_others_desc:0 "We should send some help to [From.GetName] for their rural infrastructure"

完整例子

下面是本wiki页面中所有决议和任务的最终版本，归入一个决议组：

find_resources = {
     develop_infrastructure = {
          visible = {
               has_manpower > 0
          }
          cost = 50
          available = {
               has_manpower > 500
          }
          complete_effect = {
               random_owned_state = {
                    add_building_construction = { type = infrastructure level = 2 instant_build = yes }
               }
               add_manpower = -500
          }
          days_remove = 10
          remove_effect = {
               add_manpower = 500
          }
     } 

     resource_spree = {
          cost = 100
          fire_only_once = yes
          modifier = {
               local_resources_factor = 0.1
          }
          days_remove = 200
     }

     help_others = {
          target_trigger = {
               OR = {
                    tag = GER
                    tag = USA
                    tag = JAP
               }
          }
          cost = 50
          fire_only_once = yes
          complete_effect = {
               FROM = {
                    random_owned_state = {
                         add_building_construction = { type = infrastructure level = 2 instant_build = yes }
                    }
                    add_manpower = -500
                }
          }
     }
}
