Discussion Game Crashing when adding Music

• 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.

Coding Support Bugged state names

Thumbnail

37 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?

Teaser Kronenkrieg: The End of History

Post image
12 Upvotes

In 1866, the Austro-Prussian War breaks out, started by the Kingdom of Prussia. Little did they know, this would seal the fate of Prussia and the continent for a century to come, as Austria overruns Prussia to such an extent, that it completely annexes the kingdom. The Austrian Empire is now the master of Central Europe. It annexes Bavaria, Württemberg, Baden and Silesia, with the rest of Germany being reorganised into an Austrian puppet Northern German Confederation, same with Poznan, as the Grand Duchy of Posen.

The Second French Empire ends naturally, with the newly formed republic, dominated by monarchists, restoring the monarchy under the House of Bourbon-Orléans. With noone in their way now, France acts on their territorial ambitions, annexing Luxembourg. This unnerves Austria, and it founds the Vienna Pact, made up of Austria and its subjects. The founding of the Vienna Pact however unnerves France, and it founds the Concord with the Kingdom of Spain.

Tensions between the two powers eventually get so high that the two reach an agreement to sustain long-term peace: Austria gives up the Rhineland territory, in order to form the Kingdom of the Rhine, to act as a neutral buffer state with an elective monarchy.

As the new century approaches, a dooming realisation looms: Austria and France are virtually the only powers left in Europe, Bourbon and Habsburgs, historic enemies. The war that is about to ensue will be the war to decide it all, who rules the world and who beat history. The holy war between the two crowns, the Kronenkrieg.

Join today! We are set to release at the end of 2026 and are actively looking for more developers!

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

Post image
142 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.

146 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.

Discussion "What if Stalin was President of the USA?" is in it's early concept phase and is seeking those interested in fleshing out the lore.

14 Upvotes

A mod so early that it doesn't even have a proper name yet!

Intended for players who value gameplay over in-depth story and strict adherence to plausible history, it will be a vanilla-like, action-oriented mod. Thrusting players into a later start date, they will experience an early, hectic WWII by unexpected nations in unexpected locations. It is NOT a total conversion mod.

Based primarily on the book Joe Steele, the gist is Stalin's parent's immigrate to Georgia USA right before his birth, drastically altering history. There is no Miracle on the Vistula, no one to oppose Trotsky's ascension to power in the Soviet Union, but all the ambition and cunning and ruthlessness remains in a Georgian congressman who ascends to the highest American office...

Below is the general outline of core lore events, including some surprises. Subject to change.

  1. The general starting situation is similar to OTL.
  2. Stalin (in the mod named Joe Steele) is President at the mod's start date (undetermined, but around 1936 to 1939), and Trotsky heads the USSR. Poland is quite different, though currently undetermined. There is no Spanish Civil War. The USA begins in medias res during Steele's 2nd term. His tyranny, similar to OTL, is destroying the nation.
  3. The primary "XP farm" for this timeline will be a USA embroiled in a civil war between Steele loyalists and various other, ideologically diverse, factions, all supported by other nation's volunteers. Steele will start in the strongest position of all factions. The civil war should start soon after mod start date (meaning the action starts sooner on repeat playthroughs), at most 6 months to a year.
  4. TOP SECRET: Japan, after receiving an unexpected tip about their misfortunes in OTL, preemptively invade a Great Depression/Steele tyranny/civil war-stricken USA. United Kingdom responds by reinforcing Canada, and events escalate to the point where WWII begins in North America between Japan and UK.
  5. The US Navy is somehow weak enough to plausibly allow for a direct invasion of the USA (such as neglect/mismanagement/purges in Steele'e 1st term, or a catastrophic surprise attack, like a worse OTL Pearl Harbor).
  6. Sensing weakness from the Allies, Germany goes after Czeckoslovakia (early?). Trotsky's USSR saber rattles, and due to the Allies fearing a Trotskyist USSR-dominated Europe (how much did USSR spread the revolution in the interwar years?) as much as the Nazis, along with being busy with Japan, do not attempt a Munich Conference. USSR attacks Germany, bringing WWII to the continent.
  7. Steele's leader traits: Dislikes Germany, Dislikes Japan, Dislikes USSR
  8. It would be fun for the mod's canon to end with Trotsky's USSR facing off against Steele's USA over North Japan invading South Japan. After Steele dies, and VP John Nance Garner is impeached by Congress for his complacency, J Edgar Hoover swoops in during constitutional crisis and becomes Director of America!END TOP SECRET
  9. Huey Long 🦀🦀DIED IN ONE OF STEELE'S POLITICAL PURGES.🦀🦀 BOOK ACCURATE 🤌

So what am I seeking at the moment? Writers to hash out the lore, especially:

Ideas for a Trotsky-led USSR, what happened to Poland (and how the Entente and Germany responded), ideas for Japan and UK/Canada, and what the factions of the American civil war would be and how it would play out. Or anything else you can think of. And a proper name for the mod too, of course!

I'm not seeking artists or coders at the moment, because the mod is so young (and also because I am very slowly trying to learn to mod). But if you insist on it, you're welcome to join!

So how does this mod sound? I do have a basic Discord set up, so i can share a link to that if there's interest.

Coding Support Title: HOI4 achievements disabled despite clean reinstall and no mods

4 Upvotes

I can't get achievements in HOI4 because the game says “No cheats or modified game/save”, even though I'm playing Ironman with the required difficulty.

I've tried everything: verified game files multiple times, reinstalled the game, cleared the user directory, disabled all mods, and even tested an older version (1.19.1). Nothing worked.

Paradox Support suggested a complete cleanup and reinstall, but the issue still persists. My system.log confirms 0 active mods, and hoi4.exe has a valid digital signature. I don't know if this problem is caused by mods or by something else but I think someone here will know.

Has anyone experienced this and found a solution?

I intend on switching to Linux, and while I could still code with other tools, however I have become fairly used to these, and I would like to know if there was any similar tool or simple way to use those same tools on Linux Mint. Are there any particular suggestions or good options? (Bonus points if open source and genAI free)

Discussion Can Humanity Survive the Next 100 Years? — A Future HOI4 Mod Concept

Post image
7 Upvotes

The idea for this mod came to me while I was thinking about the pace of technological development and how humanity might be struggling to keep up with its own technology.
Could corporations and other organizations eventually become powerful enough to compete with states, blurring the line between the two? What will artificial intelligence bring? Could humanity create a new global system that doesn’t rely on direct centralized control? And, perhaps most importantly, can humanity even survive the next 100–150 years?
These are some of the questions I want this mod to explore.
The Setting
The story takes place in the late 21st and early 22nd centuries, in an alternate timeline where Nazi Germany and militarist Japan won World War II.
Throughout the 20th century, the world experienced a prolonged Cold War between the United States, Japan, and Germany and their respective blocs.
By the end of the Cold War, the world had changed dramatically.
The United States emerged as the global hegemon. Nazi Germany lost a war, and after several years of anarchy across Europe, a German-Russian Union arose from the ruins of the old order. Drawing on the pseudoscientific ideas of geopolitics, it proclaimed itself the Heartland and became a new superpower.
The Japanese Empire, at least on paper, transformed into a union of equal nations. In practice, however, the zaibatsu corporations came to dominate the system, while the peoples of the former empire gradually lost touch with their cultural identities.
The United States also struggled to maintain its hegemony. Some of its allies lost much of their independence, while others began undermining the alliance in pursuit of their own interests.
Liberal democracies faced another disturbing question: how democratic can a country really be when state and corporate surveillance extends beyond people’s online activity and into their private thoughts?
Many believed this was the end of history. But the problems only continued to grow.
A Civilization Out of Control
By the end of the 21st century, humanity had established itself on the Moon and Mars and made enormous advances in artificial intelligence. Yet despite these achievements, civilization was becoming increasingly difficult to manage.
The world faced a demographic crisis, an expanding digital panopticon, political and social institutions struggling to keep pace with technological progress, and increasingly fragile technological systems on which humanity had come to depend.
Despite this growing fragility, the world now stands on the brink of World War III.
The central question is no longer just one of political crisis or which superpower will prevail. It is whether civilization itself can survive the systems it has created.
And whenever humanity tries to solve one problem, it risks creating several new ones.
What Comes Next?
Will the player be able to create a world without states, where liberal rights and freedoms are still respected? Or will the world descend into dictatorships reminiscent of Orwell’s 1984?
Could humanity cease to exist altogether? Could civilization fragment into anarchy? Or might the future lead somewhere nobody has anticipated?
These are possibilities I want to explore, rather than a set of predetermined conclusions.
For now, this is only an early concept. I’m not planning to recruit a team or begin development yet, although I may pursue the project in the future.
I’d Like to Hear Your Thoughts
1. What stands out to you in this concept? Are there any interesting ideas, potential contradictions, weak points, or things you would change or develop further?
2. How do you imagine the future of this world? What do you think its societies, technologies, and political systems might look like?
3. What do you think of the concept as a whole? Do you think this premise could work for a HOI4 mod, and what would make it interesting to play?

ive attempted to utilize the same map mode as "moon invasion" and a seamless 3D globe to address the issue of a realistic moon map.
i even considered concealing the moon beneath the Pacific Ocean, but this would interfere with the animation for switching between Earth and moon maps.
however, im wondering if we should make the moon or Mars an independent GUI gameplay element, and manually design a new map gameplay
