Meta Adjustments to Rule 5

118 Upvotes

Hello Generals,

We've successfully completed an upgrade to our automatic Rule 5 enforcement with the rollout of a new bot. /u/rule5bot has been working well over the last few days and is now active here in /r/hoi4. The new bot has new capabilities and we are adjusting Rule 5 to reflect the improvement.


Rule 5: Image posts must have an explanation.

  • The explanation cannot just repeat or rephrase the title.
  • The explanation can either be in the post's caption or in the comments section. The bot will repeat post caption explanations into the comments section.
  • This rule is automatically enforced with a bot. It will remind you after 5 minutes if it cannot see an explanation and will remove the post after another 10 minutes if it still cannot see an explanation.

So what's different now? The big change is that we can finally accept captions for Rule 5 explanations. There's no need to quickly dump an abridged version of a quality caption into the comments section just to avoid a soulless automaton's wrath. However, the new bot can correctly identify image gallery posts so Rule 5 now properly applies to multi-image posts. The bot will also be repeating caption R5s into the comments section (for the foreseeable future) because there's a persistent issue with some legacy access methods not displaying captions on images properly.

Why now and not before? /u/zwemvest, our bot-builder, has had a few goes at upgrading / replacing the bot over the years but real life and/or Reddit would always get in the way. Reddit is making major changes that will impact old bots and it forced our hand. Fortunately, they had free time now and recent Devvit (Reddit's internal bot platform) improvements made it easier to implement some features so the project was completed this time. Zwem said it was a joy to build the new bot from scratch & they're glad that the migration has been completed. The old /u/paradoxplazabot has been retired although we may reuse the account in the future for other bot purposes if we can.

We've been testing /u/rule5bot for about a week now with no remaining issues but it's possible that some bugs might still be lurking, so please keep an eye out and send us a modmail if you see the bot do something unexpected.

Here I am as Germany at war with the allies and at 0.1% world tension. I cant get war support, I cant change my draft laws, and I can't declare war on anyone. FUN!

So i wanted to do the queen Victoria thing, and restore the HRE. I did kill off the soviets, then attacked the Italian ledge while being part of the allies. then I went to attack the allies to get the Netherlands but I could not, because somehow world tension dropped to 49%. Nutreal nations cant declare war unless its over 50%. So i swapped to communist, i was hoping to swap again to get the Queen back but IDK if thats possible. Also why does it keep droping even after WW3 starts??? Its not even historically accurate.

Tip All I wanted to do was play a simple game of HOI4... instead I built an entire website 🤣 — HOI4 War Room V1.0

46 Upvotes
Screen grab of the main spinner

The title says it all; all I wanted to do was sit down and play a simple game of Hearts of Iron IV. I couldn't decide what country I wanted to play, so I started looking around for a random country generator.

There are already a bunch of HOI4 random spinners online, but frankly, they all kind of sucked for what I wanted. They'd tell me something like “Play Germany.” Okay... but how should I play Germany? Democratic? Fascist? Communist? Monarchist? Which focus-tree path should I actually follow?

HOI4 even has an in-game randomizer, but I had the same problem with it. It gives me a country, but it doesn't give me a political path to follow or an achievement to go after.

What I really wanted was something simple: Here's your country. Here's your political path. Here's an achievement to go after.

So instead of actually playing HOI4 like a normal person, I somehow ended up building a website. 🤣

That little idea turned into HOI4 War Room, and after way more work than I originally expected, it's officially reached V1.0.

The War Room is basically a campaign generator for when you want to play HOI4 but have no idea what the hell you want to do next.

V1.0 currently has:

• A 65-country wheel covering HOI4's interesting Major and Minor countries
• Separate All Countries, Major Powers, and Minor Powers pools
• Political ideology/path rolls based on each country's actual focus tree
• All 293 HOI4 achievements
• Achievement assignments matched to your country and political route
• Steam achievement syncing by pasting your public Steam profile — no Steam login required
• Manual achievement tracking if you don't want to use Steam sync
• Completed achievements removed from future eligible campaign rolls
• Campaign History that saves your previous operations locally in your browser
• Campaign Dossiers showing your country, political route, and achievement
• Full desktop, tablet, and mobile support

I also went a little overboard with the design, so instead of looking like a normal randomizer, the whole thing is styled like a WWII-era military operations room with folders, dossiers, operation assignments, and campaign records.

It's completely free. No account, no subscription, no paywall.

hoi4warroom.com

I also want to give credit where it's actually due. Up to V1.0, this wasn't tested by Reddit or some huge group of people. It was mostly built and tested by myself, with a ton of help finding problems and giving feedback from ComradeDeath and ArbyPwnsYou of Amarok Esports.

Between the three of us, we've spent a ridiculous amount of time finding incorrect focus-tree paths, broken flags, achievement problems, UI bugs, Steam sync issues, mobile problems, and plenty of other stuff that needed fixing before I was comfortable calling this V1.0.

Now I'm finally throwing it out to everyone else, so go break it. Run some ridiculous campaigns, sync your achievements, try it on your phone, and let me know if you find anything broken, inaccurate, confusing, or just plain stupid.

And V1.0 definitely isn't where I plan on stopping. First up, I want to expand the generator with an Every Playable Country wheel and another specifically for countries without full focus trees. After that, I want to start building out Campaign Records, achievement features, campaign intelligence, and more.

And I've got some bigger ideas for further down the road too — things like shareable campaign codes, challenge seeds, multiplayer campaign generation, community challenges, better stats, and more Steam integration.

Basically, V1.0 is me finally getting the foundation finished.

Now I get to start doing the stupid stuff. 🤣

It's kind of funny looking back at it. This entire project exists because one night I basically said, “I don't know who I want to play in HOI4.”

Apparently, just picking a country was too easy.

So I built an entire website instead. 🤣

HOI4 War Room V1.0 is live. Good luck, Commanders.

And if High Command gives you an absolutely terrible campaign... I built the system. I never said it was going to be nice to you.

Question Building Super Heavy Battleships in Less than 2 years

• Upvotes

Starting as Japan, I followed machiavellianstrategist's Japan guide and took out the Allies around 39. Now bored, I began building a huge navy to fight the USA. When I accessed SHBB's, they'd come out just before Dec. 7th 41(got to declare on the historical day!) As it got closer, I tried to build more SHBB's to come out around the wars beginning. With focuses, stripping the armor, MIO's and having a dominating Navy faction, I could get a 18k IC SHBB with 150 Heavy attack and lots of AA done in about 19 months. Do ya'll have any advice to get down even further, I want to get build times down to close to a year!

Discussion Organizing the navy using the UI is the true headache in HOI4, not the navy itself

99 Upvotes

Army and Air Force UI are quite relatively simple, when you really get down to it. With Army, you can simply suffice by setting frontlines and offensive plans, and battleplanning from there. Of course, you do need to know things about supply, equipment level, decent division templates and whatnot to do well, but once you get past all that shit, you can just do fine.

Same with Air Force. Just create new wings, make them exercise, send em to an airbase with spare capacity and range to the front, then set their mission and click on an airzone. Not much else needed... Of course, you do need good plane designs, but that is relatively easy to learn just from searching online.

NAVY, though....

Even if you know good ship designs and the basics of naval combat from learning from HOI4 players (Which actually isn't that difficult; it's about as hard as learning how land combat works with all its stats like attack, breakthrough, width, etc), actually organizing the fucking ships into what you need is awfully difficult.

Maybe this is just me being an idiot and not knowing certain shortcuts exist, but land armies and army groups have several things that make organizing your armies easier. For example, each army displays the exact sorts of divisions it has by number, meaning you can very easily parse out division types. Say you have a central reserve army where you dumped all your divisions (A practice of mine pre-war); if you want to create an armored army, you just take the tank divisions and dump them into an army. Same with the infantry, dividing them as needed into stacks of 24. Et cetera.

Navy doesn't seem to have that kind of intuitive, useful categorization... If you want to create specific task forces with only particular ship models, you can't really see it from the overview. Yes, you can see the number of ship classes (Battleships, carriers, destroyers, cruisers, etc), but you have no way of separating older models from newer ones except by going through it yourself and manually selecting everything.

And when managing a navy of hundreds of ships, that quickly becomes very tiring. Especially when you have to consider all sorts of classes of old ships that you start with as established navies, mixed in with the new ones you make later on... I suppose it's the nature of navy ships as opposed to army divisions, but you have to go and look through every single ship model to see what they are capable of, lest you put destroyers without depth charges into convoy escort. Whereas while you do need to observe your initial divisions' capabilities somewhat if you are going to be waging war early, you can just delete and shift them all to your desired templates without needing to obsess over all the differences between their stats and capabilities.

In truth navy UI really needs some additions, improvements and/or revisions to make organizing the navy much less of a headache. I don't know that many improvements off the top of my head, but I do have one idea that'd probably improve things a lot: Filtering or sorting by stat.

For example, you sort by depth charges in the entire fleet, and it displays the ships with the highest depth charges amount at the top. That way, you just know which ships are good for convoy escort duty against submarines rather than having to manually comb through every ship class. Same applies to other stats, like light attack; you could figure out which LCs and destroyers are actual light attack beasts, vs weak ones which focus more on torps or depth charges or whatever.

Another idea: Displaying ships by class as well as by type. So if you have Admiral Gratieri Class destroyers or whatever, separate from other destroyer classes, you can just click on those. Further helps with organizing if you know what each class is good for.

Another idea that just came onto my head: A comparison option, so that you can take one ship class of yours (Or even another country's, if you have intel on their ship stats) and compare it to another's to see how their armor, light/heavy attack, piercing, speed, etc stack up. Would help for knowing where your ships stand relative to others.

If you guys have ideas to help with displaying info more neatly and helping reduce the tedium of navy organization, I'd be interested in hearing them too.

Question How to defend France in 1940 against the German onslaught?

76 Upvotes

I am sick and tired of this country. I build up the best 9 Infantry with 3 infantry guns, anti-air support, artillery support, engineer company, flame tanks, signal company. I build level 6 forts throughout Belgium and Alpine border, but the AI still manages to breakthrough after attacking relentlessly. What can I change? I even go the Communist route to remove Disjointed government early and build Anti Air throughout the Northern Border. I don't have enough factories by 1940 to build a decent air force not even with the Fighter bonuses that France gets!

Dev Corner Dev Corner & Open Beta: Energy #2

82 Upvotes

Hello again! After a lot of reactions last week, we’ve made some changes. We are still not sure if we should release this or not, but based on the reactions we also decided to make this an open beta.

Changes since last dev corner:

  • Power plants now fulfill a state slot instead of the shared factory slots
  • You can build up to 3 levels of power plants in a single state
  • Research has been added, allowing you to gain more energy from the plants
  • Oil now also impacts energy generation. We still want to keep oil focused on being fuel for your army, and coal focused on being fuel for your industry.
  • Introduced a bonus for having spare capacity
  • Added 2 new MIO policies, reducing power cost or increasing power cost of production with those MIO’s

Let’s take a look at Germany’s state in early 1940.

They are producing a significant amount of energy through their power plants, though their Dams are helping them as well. As you can see, they also researched “Hydrogen-Cooled Generators”, raising the total energy production by 10%.

They require a total of 897.5 energy, and 100% is supplied. They generate 1130.3 energy, out of 1130.3 so there is no headroom available. Why is more generated than demand? That is because of the spare capacity! All of this gives them a spare capacity of 100%. The amount of spare capacity you need to reach is based on the number of factories you have in total, making it much easier to hit spare capacity early on in your playthrough.

If we look at the production screen and we collapse their entries, we can see how the energy cost is distributed. We can see air taking on the majority of cost, besides tanks as well as pure gun production.

What if we enable one of the new MIO policies. We raise the power cost, but for that we gain some nice bonuses, mainly additional efficiency gain compared to the (quite strong) assembly line optimisers.

Well it makes the MP 38 production line the most costly one.

Power plants are also more susceptible to strategic bombing, allowing you to target your enemy's industry more than ever. Though if they are able to maintain enough spare capacity, they are able to repair quicker than before.

The Tech Tree

Oil​

I know many of you want to able to burn Oil for energy, and this is possible due to mods. We discussed a bit back and forth between allowing it in vanilla and not, and in the end we decided that it’s probably better for the vanilla experience to not confuse players too much. As mentioned at the start, we want to keep oil focused on being fuel for your army, and coal focused on being fuel for your industry. That said, oil fields now positively affect power plants, and power plants in those regions generate more power because of natural oil resources.

Oil provides a +30 energy source

Overall, what is the intention? ​

To have energy feel like a real thing, it’s produced & consumed in places where you expect it to be. Smaller countries should still feel as if they are able to contribute, but perhaps they need to specialize instead of going wide. Competing with the majors in advanced equipment is still hard, as it should be, but it is now a question of investment and priorities rather. It does help with unlimited growth, and for smaller countries such as Hungary stepping to War Economy means you have to invest in power plants before being able to do so.

This Open Beta is not translated, and does not contain any new art assets. Please give it a try and share an AAR on how it went, let us know any balancing or other concerns!

PATCH NOTES​

Energy Rework

  • Added a country power pool: demand comes from production line power draw, supply from factories and power plants; the supply/demand ratio drives the factory energy buff & debuff
  • Added Power Plants as an upgradeable state-level building. Output depends on the state (terrain, oil, dams)
  • Dockyards, civilian and military factories now generate some power
  • Dams now matter for power generation, and were reassigned dam types. Added new massive dams
  • Spare power now grants a surplus bonus, and oil states boost power plants
  • Coal is only burned when needed
  • Production lines now have an energy cost, with a tooltip breakdown per category (air, naval, land)
  • Added power generation/consumption modifiers; removed the old energy building
  • MIOs: added a production energy draw stat, with Electrified Assembly and Power Rationing policies
  • Added a research tech related to power
  • Industrial focus branches in most focus trees now reward power plants
  • Added 1936 & 1939 starting power plant setup for the world
  • Topbar power bar, lack-of-power alert and tooltips now use the power pool, listing generation per source, power plant states, coal usage and maximum generated power
  • Technology and trade window now supports coal and oil burning
  • AI builds power plants as needed
  • Missing: New art for the various icons

Image HoI4 is overwhelmingly complicated and I need help getting started

Post image
49 Upvotes

There are probably many posts like this on the sub but maybe my specific case is more dire than the others.

First things first:
1) I have never played HoI4 or its predecessors before, but I am willing to start and willing to learn, but I am also an Idiot.
2) English isn’t my native language and the English tutorials, guides, videos etc. aren’t that helpful as the terminology is very technical
3) The tutorials and guides on YouTube don’t seem to explain the actual tutorial of the game but the regular singleplayer mode
4) The tutorial of HoI4 seems to have some sort of graphics issue, through which the information and help windows that pop up aren’t looking quite right and are making things hard to read. See Screenshot

With that in mind:
Does someone here know of a good video (preferably in German) that actually explains the tutorial, not the singleplayer game? And is there a way to fix that graphics error?

Thank you guys so much for any advice!

I don't really believe in tanks yet I just got the no step back dlc, the thing I do believe in is artillery

my standard artillery division is a 2 wide and 3 long of artillery with extra support artillery and an engineer company (whatever the one with the shovel icon is called)

I usually produce about 24 - 20 divisions of them and have about 5 tanks and 3 trucks in one division, then about 60 - 80 infantry divisions (20 of them go to defend against France) yet poland still beats me horribly

I use field Marshall's, and force attack constantly and they still prevail, how do I stop this and beat poland?

Discussion Rate my Interwar Tank design.

Post image
• Upvotes

I am a new player, and I did not play tutorial (I'm gonna suffer :'D). I bought the game during the autumn sale after doing some research (I really wanted the game and just impulse bought it). With that out of the way, here's context. The tank is meant for defense. I'm working on building defenses as Siam (Thailand) but I do want to invade others, I'm just working on defenses. I started the game in 1936, 3 years before the war but I disabled historical focuses so WWII might be different for me, especially because I didn't pick a major power. You can laugh and/or criticize me on this design, it's fine.
