==深入介绍==
正如其他p社游戏一样，Vic3也有ROOT,PREV,THIS,FROM这些定义域。

For specific scope, it starts with certain letter, such as var,p,s,c,law_type. Using them with <code>:</code> followed by ceratain name can call the scope, e.g, <code>s:STATE_MINNESOTA</code> call a state_region scope names STATE_MINNESOTA.

Scope can be linked by [[Event targets]], they are series of function to linked to output scopes from input scopes.

<code>s</code> is an [[Event targets]], also it requires data, therefore it must followed by <code>:</code> than the ceratain name to call the scope. Due to <code>s</code> is global link [[Event targets]], It can be used independentlly. 
<code>region_state</code> is not global link so it sould follow by <code>.</code> after a state_region scope.

By <code>.</code> can quickly link scopes. The most common example is <code>s:STATE_MINNESOTA.region_state:USA</code>, firstly is state_region scope than by <code>.</code> link to state. Further, add one more <code>.</code> is possible, just like <code>s:STATE_MINNESOTA.region_state:USA.var:usa_state_flag_block</code>

However, some of scope can not be quickly switch, due to the parent scope is uncertain. diplomatic_play usually is uncertain scope, and then [[Event targets]] should be considered

<syntaxhighlight lang=perl>
random_diplomatic_play = { 
    # random,every are to used in really effect, any is to used in trigger
    # random,every and any is all uncertain, can not use . to link next scope
    limit = {
        is_war = yes
    }
    initiator = { change_infamy = 5 } # initiator is event target of diplomatic_play, it outputs a country
}
</syntaxhighlight>

这是详尽的例子:
<syntaxhighlight lang=perl>
example_event.1 = {
	type = country_event # 定义了ROOT为发生的国家，而不是发生的人物或者地区
    random_diplomatic_play = {
        limit = {
            is_war = yes
            any_scope_play_involved = {
                THIS = ROOT # THIS 就是当前的定义域。 在这里 THIS就是any_scope_play_involved
            }
            NOR = { # not or 
                initiator = ROOT # initiator 和 target 是diplomatic_play的事件目标
                target = ROOT
            }
        }
        initiator = { #  initiator 仅能使用在 diplomatic scope 这一定义域
            save_scope_as = initiator_scope # 因此，为了让其他定义域调用，需要保存定义域
        }
        target = {
            save_scope_as =  target_scope
        }
        if = { limit = { ROOT = { is_diplomatic_play_enemy_of = scope:initiator_scope } } # 转移定义域到ROOT
            if = { limit = { scope:initiator_scope = { infamy >= infamy_threshold:infamous } } # 在ROOT定义域里使用initiator的scope
                ROOT = { change_infamy = 5 }
            }
            ROOT = {
                set_owes_obligation_to = {
                    country = scope:target_scope
                    setting = yes
                }
            }
            remove_target_backers = { ROOT } # 移除外交博弈目标支持者，只能显示，没有效果，令人沮丧
        }
    }
 }
</syntaxhighlight>

==地区定义域==
First of all, let me clear up the difference between a  and a mere .
首先，有必要甄别"state region"和"state"的区别

用{{Flag|西班牙}}为例, 其拥有一个名为 "STATE_GRANADA"的"state region". "STATE_GRANADA"被{{Flag|西班牙}}和{{Flag|大不列颠}}同时拥有, "STATE_GRANADA" 也因此裂成了两个 "split state". {{Flag|大不列颠}}有一个 "British STATE_GRANADA" 而 {{Flag|西班牙}}也有一个 "Spianish STATE_GRANADA". 整一块"state region" STATE_GRANADA 就变成了两个叫做 "British STATE_GRANADA" 和 "Spianish STATE_GRANADA"的”states“. “state”的名称由占有地块相对数量决定，比如说{{Flag|西班牙}}有 STATE_GRANADA的绝大多数地块，因此"Spianish STATE_GRANADA"直接就叫做"STATE_GRANADA"

这是模组制作中一个很重要的概念，一言以蔽之：
# 地理性质的，一整块的称为"state region"
# 国家对"state region"占有的部分称为 "state"，无论这个国家拥有全部还是部分。

举例子来说:
<syntaxhighlight lang=perl>
 s:STATE_AMAZONAS = { # 这是地理意义上的state region
     add_homeland = brazilian 
 }
 s:STATE_AMAZONAS.region_state:BRZ = { # 这是这是巴西占有的state
     set_state_type = incorporated
 }
 
</syntaxhighlight>

A list of all the vanilla state regions is available [[List_of_state_regions|here]], and is useful to easily find the tag you need.

To learn how to change state traits you may wanna check out the workshop mod "More State Modifiers".

== 建筑定义域 ==
Although technically there is a building scope, in practice, game logic that involves buildings is done indirectly through the state scope.
Here's an example I use in one of my mods. Check if a specific country, in a specific state region it owns, has a specific building in level 2.
<syntaxhighlight lang=perl>
 c:SIA = {
 	any_scope_state = {
 		state_region = s:STATE_NORTH_BORNEO
 		any_scope_building = {
 			is_building_type = building_sulfur_mine
 			level >= 2					
 		}
 	}
 }
</syntaxhighlight>

The letter to scope buildings is "'''b'''". However it's uses are very limited and is mostly used for basic world building.
<syntaxhighlight lang=perl>
 if = {
 	limit = {
 		exists = state.b:building_sulfur_mine
 	}
 	add = state.b:building_sulfur_mine.level
 }
</syntaxhighlight>

==其他定义域==
其他的定义域大同小异，都是特定符号加上:

===国家定义域===
Scoping to a country you use the letter "'''c'''", for example:
<syntaxhighlight lang=perl>
 c:SIA = {
     add_treasury = 100 # example of game logic
 }
</syntaxhighlight>

A list of all the vanilla countries is available [[Countries#List|here]], and is useful to easily find the tag you need.

=== 文化定义域 ===
Culture scope seems to work in a similar fashion to buildings scope, indirectly referenced. However has more use cases.

Scoping to a culture you use the letters "'''cu'''", for example:
<syntaxhighlight lang=perl>
 state_region = {
 	is_homeland = cu:greek
 }
</syntaxhighlight>


===利益集团定义域===
Scoping to an interest group you use the letters "'''ig'''", for example:
<syntaxhighlight lang=perl>
ig:ig_landowners = {
	remove_ideology = ideology_paternalistic # example of game logic
	add_ideology = ideology_republican_paternalistic
}
</syntaxhighlight>
 

The different interest groups tags are:
{| class="wikitable"
! Pretty name !! Tag name
|-
| Armed Forces || ig_armed_forces
|-
| Devout || ig_devout
|-
| Industrialists || ig_industrialists
|-
| Intelligentsia || ig_intelligentsia
|-
| Landowners || ig_landowners
|-
| Petite bourgeoisie || ig_petty_bourgeoisie
|-
| Rural Folk || ig_rural_folk
|-
| Trade unions || ig_trade_unions
|}

===市场商品定义域===
Scoping to a market good you use the letters "'''mg'''", for example:
<syntaxhighlight lang=perl>
 mg:tools = { 
     save_scope_as = cool_tools # game logics
 }
</syntaxhighlight>
