Important HOI4 Modding Information + Discord Server

54 Upvotes

Tips

• If you are making your first mod, start small with content for a single country rather than with total overhauls, especially related to the map.

• Use proper indentation in your code and comments when possible, with guidelines and easier ways to do it outlined in https://hoi4.paradoxwikis.com/Modding#Indenting. This will make it easier to read, making it easier to debug for you and others.

• Check base game files for code examples to possibly adapt into the mod regularly.

• As a lead developer, you should be prepared to do the majority of the work for the mod rather than expecting others to do it.

• Use a good text editor, such as Notepad++, Sublime Text, or Visual Studio Code.

• Don't use hoi4modding.com: it has less functionality compared to manual editing and commonly produces broken code.

• Always check articles on the HoI4 Wiki at https://hoi4.paradoxwikis.com/, as they provide a lot of info and can point out some common errors on the topic.

Hearts of Marble - GFX & Tech

Thumbnail

16 Upvotes

New teaser for Hearts of Marble, a mod set in June, 14 AD, two months before Augustus, first emperor of Rome, dies. The mod currently focuses on the main powers at the time; the Roman Empire of course, but there's content for the Arsacid Empire (Parthians), the Xin dynasty and the Xiongnu, in addition to minor content for nations such as the Cherusci or the nomadic tribes of Central Asia.

As my efforts continue, here's a few sneak peak into next update (0.4) rework of some GFX and the adding of new ones for Armenia, Parthia and the Xiongnu! In addition, a small sneak peak into the tech rework (a bit outdated but still)

ive been on and off working on my passion project for the past little bit and im feeling a bit uninspired. so, heres some updates!
if you recall from my last post (I AM PLANNING SOMETHING BIG AND I CANNOT TELL YOU) ive been working on my passion project based off a shitty map i made in r56 back when i didnt mod and got into map painting. heres some actual stuff ive made!

north america is currently barebones. i have the states and borders done, but im still working on stuff like lore, localisation, gfx, etc. all you really need to know is: britain won 1812, and spain retains its empire in north america. its... coming along

without the pensinular war, spain remains a great power, retaining a large empire in the americas, and leading their own sphere of influence with bourbon-burgundy and the two sicilies. joseph bonaparte is instead crowned king of portugal, with the portuguese monarchy fleeing to brazil. spain (being an ally up until napoleons victory) is awarded porto and the algarves, but after a popular uprising in porto city, and subsequent mediation from britain and the other great powers, the former portuguese monarchy is allowed to rule over the city of porto, with spain still receiving the west.

and flags! i love making flags and so ive taken the liberty of making custom flags for each country in my mod. theyre not my best work and bourbon-burgundy is still going through flag designs, but, theyre work ive done so... read em and wheep!!

thats all i have done. or... not all i have done, but thats all the stuff im ready to show off right now. france, italy, and germany are all still in the works, and i wanna push out a toozer hopefully before halloween, if not before american thanksgiving and black friday. so... yah!

edit: god the spain flag looks fucking UGLY in game. so, ill just be using the normal kingdom of spain flag. i could try to work sum up aswell but its alot of work id rather spend on another flag. idk

Resources/guides for creating GFX for a UI?

1 Upvotes

I'm trying to make a UI for the country politics view for a mod before trying to redesign everything else. I already know how to move and adjust the elements; what I'm trying to do is create the GFX for them. Are there any resources or tutorials that would help with this?

If it helps at all, I am trying to design a UI that people from around the year 2000 would imagine what a computer UI used by some secret government organization would look like in 2016. So it'd be primarily using dark colors, but not completely black so the shadows used in ideas and such can be seen.

Discussion Civil War China Post GAW (TFR) in Autumn Begonia

Post image
61 Upvotes

Inspired by the positive response to the last post about post-Catharsis Europe in Magna Europa, this time it was built off Autumn Begonia and the following reference images. There are a few things which are stuffed up but I can't be bothered fixing (Buryatia being the main one). The reference images are below.

Again the size of these map mods allow people to get hyper specific with factional elements so if I have motivation and get some ideas (which people should leave below) I may add them in. NGL the Falun Gong being an entire country cracks me up.

And again if I were to make this into an actual mod this would not be the start as outline in my other posts with the borders being radically different, and factional players being a lot stranger to some degrees (I want AI San Zu taking over Northern China fighting against a gene soldier claiming to be Timurlane in an attempt to finish off his final conquest of China, this is the type of schizo TFR universe is for).

Discussion Post Catharsis Europe in Magna Europa (not a teaser)

Post image
194 Upvotes

A rough aproximation (its certainly not perfect but I can't be bothered to fix some errors right now) of post-catharisis Europe from that famous TFR post in the Magna Europa Map.

If I can pull together the willpower after exams I may try and make something more from this, if you want to suggest some more countries or crazy crap for this or even provide some official TFR material please do. However if I do actually try and manifest this into something serious it will probably be set in the 2060-80s so the map will defintely be radically altered and I imgaine something closer to Crusader King's After the End Europa mod.

I've also envisioned similar scenarios for an America which essentially has been united under the crazy right and eventually implodes into various insane groups, while China after the death of Loji splits into a similar chaos where rival AI personalities and various different groups fight for control of the Mandate of Heaven or something.

If you're got ideas and stuff send me a message and I may post updates if I can be bothered. Also if you're a member of Magna Europa if I seriously decide to work on this I will not be uploading the mod without your permission, if you are a developer of the mod I would like to get into contact with you about using the map as a base. :)

This is not a teaser per rule 8.

Teaser Project Kessilian / Hearts of Durasteel Development Update

Enable HLS to view with audio, or disable this notification

217 Upvotes

It's been about 6 months since my last post, so I thought I'd share some progress on the project.

I've been working on the map quite a bit, and it's now much more developed, I've included a screenshot of the global map and a video showing some of the individual planets.

Unfortunately, I also got a job, so I've been pretty busy IRL and development has slowed down even more.

The last post also brought in a few people who volunteered to help with writing events and working on the focus trees. They're busy with their own lives too, but it's great to have people interested in helping out with the project.

At the moment, the main goals for a 0.1 release are:

  • A fully working map (99% DONE)
  • Ideology leaders for every country with portraits
  • A complete Republic focus tree
  • A complete Separatist focus tree

I'm still looking for people interested in contributing, especially GFX artists. Someone who could help with the interface would be particularly appreciated, as this is one of the areas where I need the most help.

If you're interested in helping with GFX, writing, focus trees, or anything else, feel free to join the Discord or contact me here.

Coding Support Bugged state names

Thumbnail

39 Upvotes

What could the problem be? I was working on a mod, and suddenly the state names became something like STATE_977*. At first glance, I thought this was caused by my mod, but it wasn't. I tested the game without mods and the issue persisted. After that, I verified the integrity of the game files, and I even reinstalled the game completely.*

Nothing changed, I tried to find an asnwer in paradox forum but it was not good for me.

Any idea?

Coding Support Game Crashing when adding Music

1 Upvotes

I try to add custom music to my game for a mod. I follow everything for the file, OGG Vorbis files, 44.1 Khz files, but whenever I try to play the music, which show up in the game, the game froze and then stop responding. I don't know if it the files or if it the code.
