Cosmetic tag[edit]

Creating cosmetic tags is much easier than creating a complete country.

Whereas a complete country requires the chosen tag to be declared in the vanilla file in /Hearts of Iron IV/common/country_tags, a cosmetic tag is completely dynamic in this sense and scripting the tag is not required. The tag is also not required to be of 3 characters, but spaces should not be used in the tag as the game will not recognize it as one tag (the tag is not what you see in-game though once you add in localisation).

Flag[edit]

Flags are added in for cosmetic countries the same way as one would for regular countries:

Three flags need to be added:

  • A large one (82x52 pixel) in /Hearts of Iron IV/gfx/flags
  • A medium one (41x26 pixel) in /Hearts of Iron IV/gfx/flags/medium
  • A small one (10x7 pixel) in /Hearts of Iron IV/gfx/flags/small

All three should be in TGA-file format and named as follows:

<your dynamic tag>_<ideology>.tga

So for instance:

GCA_democratic.tga

It is recommended that add in flags for all 4 ideologies (_neutrality, _communism, _democratic and _fascism) are added in, as it is not possible to use only your cosmetic tag as a fallback; the flag would not change. It is possible however to use the same flags for different ideologies, as long as all 4 flags are there.

Map color[edit]

The color of a cosmetic tag can be changed by adding an entry to the game's common\countries\cosmetic.txt file:

<your cosmetic tag> = {
 color = rgb { 201 56 93 }
 color_ui = rgb { 255 73 121 }
}

Localisation[edit]

In order to change the name of your country when your scripted cosmetic tag becomes in use, one should add in localisation. To do so, go to /Hearts of Iron IV/localisation/. It is recommended to use a hex-editor such as Notepad++

By using vanilla files[edit]

If one uses the vanilla file /Hearts of Iron IV/localisation/countries_cosmetic_l_<language>.yml, the process is fairly straightforward; one should simply add their localisation the same way the others are set up:

<your cosmetic tag>_<ideology>:0 "<your desired name>"
<your cosmetic tag>_<ideology>_ADJ:0 "<your desired name's adjective>"
<your cosmetic tag>_<ideology>_DEF:0 "<your desired name as used in events>" #'the United States of America' instead of 'United States of America'

For instance:

GCA_democratic:0 "Gran Colombia"
GCA_democratic_ADJ:0 "Gran Colombian"
GCA_democratic_DEF:0 "Gran Colombia" #Gran Colombia doesn't need 'the'

By using your own file[edit]

For compatibility-purposes, it may be wise to add in your own file. It does not matter what name for your localisation file is chosen, but it has to end in '_l_<language>.yml', with <language> being the language your localisation is in. It is important to have at least english as the game will then default to that instead of the keys used by the game data when an unsupported language is used.

Once inside the file, it should be set up as follows:

l_<language>: #Should be the same as your file name's l_<language>
 <your dynamic tag>_<ideology>:0 "<your desired name>"

From here on one can follow the vanilla file guide.

Adding the cosmetic tag into the game[edit]

Adding a cosmetic tag to the game is done via Commands (aka Effects)

Effects are mostly used in:

- National Focuses
- Event Options/Immediate
- On Actions
- Decisions
- History/Countries Files

Implementing the tag[edit]

The cosmetic tag is enabled through the following command:

set_cosmetic_tag = < Your Cosmetic Tag >

You can also target the effect to another country by targeting the TAG as shown below:

TAG = { set_cosmetic_tag = < Your Cosmetic Tag > }

Using set_cosmetic_tag in a history/countries file is practically the same except the ability to have cosmetic tags be assigned after dates by doing the way shown below:

1939.1.1 = { set_cosmetic_tag = < Your Cosmetic Tag > }

This code will give the country the cosmetic tag if the starting date is January 1st 1939 or any time after
