There are 4 scopes that you can store variables
有四个作用域能使用变量
* Country
* Country
* State
* State
第9行： 第9行：
* Global
* Global


Every country, state and unit leader has its own variable list. Global scope is unique and should be used for storing variables that makes sense in a global sense, not something specific to a country.
每个国家、省份和将领都有自己的变量列表。全局作用域是唯一的，应该用于存储在全局范围内真正有意义的变量，而不是特定于某个国家的变量。


== Accessing Variables ==
== 访问变量 ==
{{SVersion|1.9}}
{{SVersion|1.9}}
In various effects/triggers, you will access a variable by giving it a name. Variable names are not case sensitive and other than a few special characters, you can use anything character you want. Although for consistency and future proof, avoid using numbers and special characters other than '_'
在各种效果/ 触发器中，可以通过给变量一个名称来访问它。变量名不区分大小写，除了一些特殊字符外，您可以使用任何您想要的字符。尽管为了一致性和未来的维护，避免使用数字和特殊字符（除了下划线"_"）


By default, you will access the variables in current scope. If you want to access a variable on a specific scope or a different you can use the following:
默认情况下，您将访问当前范围中的变量。如果要访问特定范围或其他范围上的变量，可以使用以下命令：


<pre>
<pre>
第28行： 第28行：
</pre>
</pre>


* You can use a country's tag to access a variable in that country. First example access a variable on England.
* 使用国家Tag以访问存储在国家作用域内的变量。在第一个例子里能够访问英格兰的特定变量
* You can use a state's id to access a variable in that state. Second example for example will access to Moselland which has an id of 42
* 使用省份ID以访问存储在省份作用域内的变量。第二个例子能够访问摩泽兰的特定变量
* You can access global variables by using global (3rd example)
* 使用Global以访问存储在全局作用域内的变量。
* You can access a variable on different scope by using tokens like ROOT, PREV or FROM (4th) and you can chain them together (5th)
* 使用像ROOT,PREV 或者FROM这些代码来切换到不同的作用域（第四个例子），也可以把他们连接起来（第五个例子）。
* You can access a variable on an event target by adding event_target:event_target_name before the variable (6th) or you can do * same for a global_event_target (7th)
* You can access a variable on an event target by adding event_target:event_target_name before the variable (6th) or you can do * same for a global_event_target (7th)


Variables are set to 0 by default. When you access a variable that does not exist, you will get 0 instead. You can use following to make it default to some other value
默认情况下变量的值为0。当你访问一个不存在的变量时，其值默认为0。你可以通过下列的命令来让其默认值为别的数字。
 
<pre>var_name?123</pre>
<pre>var_name?123</pre>


When you access a variable like that, it will give you value '123' if var_name does not exist.
当你访问一个像这样的变量时，如果这个变量不存在的话其默认值就会为“123”


In the rest of the tutorials, I will use var_name to access an example variable named 'var_name' in current scope but you can use all other ways mentioned here to access variables in different scopes as well
在剩下的教程中，我将使用var_name访问当前范围中名为“var_name”的示例变量，但您也可以使用这里提到的所有其他方法访问不同范围中的变量


== Variable Effects ==
== 变量效果 ==
{{SVersion|1.9}}
{{SVersion|1.9}}


Here is a list of effects that you can use to alter value of a variable.
下面是一个可以用来改变变量值的效果列表。


=== set_variable ===
=== 设置变量值 ===
{{SVersion|1.9}}
{{SVersion|1.9}}
<pre>
<pre>
第60行： 第59行：
</pre>
</pre>


or short hand
或简写成：


<pre>set_variable = { var_name = var_name_2 }</pre>
<pre>set_variable = { var_name = var_name_2 }</pre>


set_variable is used for setting value of a variable to a number or another variable. First example sets var_name to 123, second one sets it to value of var_name_2. 3rd example is equivalent to 2nd one but it is shorter to write.
set_variable 用于将一个变量的值设置为一个数字或另一个变量。第一个示例将var_name设置为123，第二个示例将其设置为var_name_2的值。第三个例子相当于第二个例子，但写起来要简短一些。


Every example that accepts var & value pair can be shortened.
每个能用到变量的地方都能写的这么简短。


One special thing about variables is you can use a value instead of a variable. This is how the first example works. In that example, 123 is actually a variable but its value is always 123 no matter what. This makes it possible to use a constant number in places that actually expects a variable.
变量的一个特殊之处是可以使用值而不是变量。这是第一个例子的工作原理。在这个例子中，123实际上是一个变量，但是它的值总是123，不管怎样。这使得在实际需要变量的地方使用常量成为可能。


But of course if you try something like:
但当然如果你写成像下面这样的话：


<pre>
<pre>
第76行： 第75行：
</pre>
</pre>


It will fail and give an error since assigning something to a value makes no sense.
它会立刻报错因为这样的赋值没有意义。


=== clear_variable ===
=== 清空变量 ===
{{SVersion|1.9}}
{{SVersion|1.9}}


第84行： 第83行：
clear_variable = var_name
clear_variable = var_name
</pre>
</pre>
This clears a variable completely. After clearing a variable, it will not exist to anymore and when you access it you will get 0 (unless it is overridden by ?)
这将完全清除变量。清除一个变量后，它将不再存在，当您访问它时，您将得到0（除非它被？）覆盖）


=== add_to_variable ===
=== 添加到变量 ===
{{SVersion|1.9}}
{{SVersion|1.9}}
Includes '''subtract_from_variable''', '''multiply_variable''', '''divide_variable''', '''modulo_variable'''.
包括“从变量中减去”、“乘以变量”、“从变量中除去”和"取余数”


These are all similar and works exactly like set_variable.
这些和设置变量的机制差不多


<pre>
<pre>
第101行： 第100行：
    value = var_name_2
    value = var_name_2
}
}
or short hand
或简写成：
 
add_to_variable = { var_name = var_name_2 } 
add_to_variable = { var_name = var_name_2 } 
</pre>
</pre>


Instead of setting var_name, these examples will add the value to it instead. You can replace add_to_variable token with other effects to use those operations instead.
这些示例将为其添加值，而不是仅仅设置变量的值，您也可以用其他效果替换add_to_variable代码以使用这些操作。


=== clamp_variable ===
=== 设置变量的上下限 ===
{{SVersion|1.9}}
{{SVersion|1.9}}


第118行： 第118行：
</pre>
</pre>


clamp_variable can be used to clamp a variable between other two variables (or values). In this example if var_name < var_name_2 it will be set to var_name 2. If it is > var_name_3 it will be set to var_name_3. Otherwise its value will remain same.
clamp_variable 能用来设置变量的上下限 ( 通过变量或者值) 。在这个例子，如果var_name < var_name_2 ，它就会被设为var_name 2 。如果它大于var_name_3，它就会被设为var_name_3。否则，它的值就会保持不变。


=== round_variable ===
=== round_variable ===

变量[1]是我们在1.5.0中添加的一个功能强大的系统。它使内容设计者能够在不同的地方存储数字（“值”），并在效果/触发器中使用它们。

有四个作用域能使用变量

  • Country
  • State
  • Unit Leader
  • Global

每个国家、省份和将领都有自己的变量列表。全局作用域是唯一的，应该用于存储在全局范围内真正有意义的变量，而不是特定于某个国家的变量。

访问变量

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

在各种效果/触发器中，可以通过给变量一个名称来访问它。变量名不区分大小写，除了一些特殊字符外，您可以使用任何您想要的字符。尽管为了一致性和未来的维护，避免使用数字和特殊字符（除了下划线"_"）

默认情况下，您将访问当前范围中的变量。如果要访问特定范围或其他范围上的变量，可以使用以下命令： 

ENG.var_name
42.var_name
global.var_name
ROOT.var_name
FROM.FROM.var_name
event_target:event_target_name.var_name
global_event_target:event_target_name.var_name
another_var_name:var_name
  • 使用国家Tag以访问存储在国家作用域内的变量。在第一个例子里能够访问英格兰的特定变量
  • 使用省份ID以访问存储在省份作用域内的变量。第二个例子能够访问摩泽兰的特定变量
  • 使用Global以访问存储在全局作用域内的变量。
  • 使用像ROOT,PREV或者FROM这些代码来切换到不同的作用域（第四个例子），也可以把他们连接起来（第五个例子）。
  • You can access a variable on an event target by adding event_target:event_target_name before the variable (6th) or you can do * same for a global_event_target (7th)

默认情况下变量的值为0。当你访问一个不存在的变量时，其值默认为0。你可以通过下列的命令来让其默认值为别的数字。 

var_name?123

当你访问一个像这样的变量时，如果这个变量不存在的话其默认值就会为“123”

在剩下的教程中，我将使用var_name访问当前范围中名为“var_name”的示例变量，但您也可以使用这里提到的所有其他方法访问不同范围中的变量

变量效果

set_variable = {
    var = var_name
    value = 123
}
set_variable = {
    var = var_name
    value = var_name_2
}

或简写成： 

set_variable = { var_name = var_name_2 }

set_variable用于将一个变量的值设置为一个数字或另一个变量。第一个示例将var_name设置为123，第二个示例将其设置为var_name_2的值。第三个例子相当于第二个例子，但写起来要简短一些。

每个能用到变量的地方都能写的这么简短。

但当然如果你写成像下面这样的话： 

set_variable = { 1 = 2 }

它会立刻报错因为这样的赋值没有意义。

清空变量

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。
 
clear_variable = var_name

这将完全清除变量。清除一个变量后，它将不再存在，当您访问它时，您将得到0（除非它被？）覆盖）

添加到变量

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

包括“从变量中减去”、“乘以变量”、“从变量中除去”和"取余数”

这些和设置变量的机制差不多 

add_to_variable = {
    var = var_name
    value = 123
}
add_to_variable = {
    var = var_name
    value = var_name_2
}
或简写成：

add_to_variable = { var_name = var_name_2 }

设置变量的上下限

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。
 
clamp_variable = {
    var = var_name
    min = var_name_2
    max = var_name_3
}

clamp_variable 能用来设置变量的上下限 (通过变量或者值)。在这个例子，如果var_name < var_name_2，它就会被设为var_name 2。如果它大于var_name_3，它就会被设为var_name_3。否则，它的值就会保持不变。

round_variable

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。
 
round_variable = var_name

This will round a variable to nearest integer.

Variable Triggers

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

There are only two triggers related to variables.

check_variable

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

check_variable will compare two variables/values with each other with a specified operator and uses it as a trigger. 

check_variable = {
    var = var_name
    value = var_name_2
    compare = less_than
}

This example compares var_name to var_name_2 and returns true of var_name is less than var_name_2.

Available compare tokens:

  • less_than
  • less_than_or_equals
  • greater_than
  • greater_than_or_equals
  • equals
  • not_equals

You can omit compare token if you want, in this case it will default to greater_than_or_equals

Short syntax can be used: 

check_variable = { var_name = var_name_2 }
check_variable = { var_name < var_name_2 }
check_variable = { var_name > var_name_2 }

First one will compare for equals, second one is for less_than and third one is for greater_than. There is no way to use other comparison methods in this way (ie >= won't work)

has_variable

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。
 
has_variable = var_name

This will check if a variable exist for a scope. clear_variable effect will erase a variable completely so has_variable will return false after that.

Targeted Variables

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

You can define a variable that is targeted at some other scope. Here is an example usage 

ENG = {
  TUR = {
    set_variable = { var_name@PREV = 5 }
  }
}

Here first we set scope to ENG and then to TUR. When we call set_variable, it will set a variable named var_name on TUR targeted towards PREV scope (which is ENG).

You can chain scopes (var_name@PREV.PREV) or use country tags/state IDs as well (var_name@ENG for example would behave same in previous example, an example for states would be var_name@42).

You can only target states or countries (no unit leaders).

Using variables like event targets

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

Variables can replace event targets up to a point. Instead of storing a value, you can store a country TAG or state id in variables and use them later in a similar way. Example: 

set_variable = { var_name = POL.id }
var:var_name = {
    set_variable = { var_name_2 = 125 }
}

This example will create a var_name variable in current scope and set it to id of POL (a unique number represents POL). After that you can switch scope to POL using this variable like we did in the example. The example here will set a variable named var_name_2 to 125 in Poland scope.

You can set a variable to a country TAG like we did in example. You can also use scopes like PREV/FROM/ROOT or chain them together. To set something to current scope, use THIS instead. If you want to set a variable to a specific state scope, you can use set_variable = { var_name = 42.id} (which is basically id on 42 scope)

You can only set a variable to a country or a state scope (no unit leader scope, they are like a bastard child of this system)

Variables and Scripted Localization

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

You can access a variable in scripted using the following in the string: 

[?var_name]

Will print the value of var_name in scope of scripted localization.

Temporary Variables

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

Temporary variables is a 'feature' (read hack) that lets you store variables that will be stored temporarily and will be deleted after the script ends. You can use those to make a calculations without , lets say you want to calculate following equation: 

c = a * 2 - b / 3

Here is how you can do it without creating additional variables anywhere: 

set_temp_variable = { temp1 = a }
multiply_temp_variable = { temp1 = 2 }

set_temp_variable = { temp2 = b }
divide_temp_variable = { temp2 = 3 }

subtract_from_temp_variable = { temp1 = temp2 }

set_variable = { c = temp1 }

These are the effects relating to temporary variables:

  • set_temp_variable
  • add_to_temp_variable
  • subtract_from_temp_variable
  • multiply_temp_variable
  • divide_temp_variable
  • modulo_temp_variable
  • round_temp_variable
  • clamp_temp_variable

In previous example, the last line sets c to temp1. If you already had an actual variable named temp1 in current scope, it will be shadowed by temp variable. So try to use unique names for your temp variables or otherwise it will be weird.

One cool about temp variables is that you can use them in triggers. Since their effects are only temporary and does not affect game play, they should be safe to use. For example in previous example we could calculate a * 2 - b / 3 same way and check if it is greater than 0 using using check_variable trigger.

Also in a couple part of the programs, temporary variables are not cleared between triggers and effects. For example temporary variables stays same for is_valid trigger of an event and their effects. So you can calculate something in trigger, then use it on effect. This is kinda weird but it has uses.

Random Variables

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

You can use a variable named 'random' to get a random variable: 

set_variable = { var_name = random }

Will set var_name to a value between 0 and 1. You can use it on triggers as well but it will give you same variable.

There are also a couple more types of randomization distributions: uniform, binomial and poisson distribution. The first type is almost identical to the default distribution, except that when using it, you can select the minimum and maximum values of the variable. Example: 

randomize_temp_variable = {
  var = num_dogs
  distribution = uniform
  min = 0
  max = 1
}

The second type can take the minimum and maximum values as the previous one, but in contrast to the previous one is more likely to take an average value, note: N=2. Example: 

randomize_temp_variable = {
  var = num_dogs
  distribution = binomial
  min = 0  # optional
  max = 10 # required if min is specified
}

The last distribution uses the lambda value to randomize the variable. When using this type of distribution, the difference between the maximum and average values of the variable decreases as the lambda value increases. Unlike the previous ones, it can only set the minimum value of a variable. Example: 

randomize_temp_variable = {
  var = num_dogs
  distribution = poisson
  lambda = 10  # required
  min = 10     # optional
}

For AI triggers (like ai_will_do modifiers), use ai_random instead.

Game Variables

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.9。

Game variables are a special read only variables. You can read them like regular variables but they are actually calculated dynamically. For example in countries you can access political power of a country and use it as a variable: 

set_variable = { var_name = political_power }

Here political_power is actually a game variable and it gives you political power that a country has. You can not edit them though, you have to use effects for those.

Some of them are automatically converted from triggers (basically any triggers that accepts country/state/unit leader/global scope and works like max_manpower = 10 can be used as game variable) but some of them are unique to modifier system.

Do not use name of game variables in your variables.

hoi4 scripting language supports storing tokens as a variable. For example you can do the following: 

set_temp_variable = { t = token:infantry_equipment }

add_equipment_to_stockpile = {
	type = var:t
	amount = 100
}

Here you are storing token infantry_equipment in a temporary variable named t and later we are using this stored token in add_equipment_to_stockpile effect.

At the moment following objects can be stored in variables and all effects/triggers should be able to accept such variables. 

ideology/ideology groups
equipment types
operation

Here is a list of game variables for each type of scope:

Global

Debugging

File:Ambox outdated info.png
这部分内容可能已不适合当前版本，最后更新于1.8。

There are various console commands to debug variables.

All this console command uses selection as a scope. If you select a state (left click a state) it will scope to that. If you select a country (right click a state) it will scope to that country. If you select an army with a leader assigned it will scope to the leader. If nothing is selected, it will scope to player country. 

set_var var_name 1
get_var var_name
list_vars
list_vars TUR

First one sets a variable to a value, second one gets result of a variable. 3rd and 4th one lists variables in the scope

There is also print_variables effect/trigger that lets you print every variable (temp or regular) to a file 

print_variables = {
    file = log_file
    text = header_text
    append = yes
    print_global = yes
    var_list = { a b c } #optional
}
