HOI4 Dev Diary - Naval Updates

HOI4 Dev Diary - Naval Updates

  • Crusader Kings III Available Now!

    The realm rejoices as Paradox Interactive announces the launch of Crusader Kings III, the latest entry in the publisher’s grand strategy role-playing game franchise. Advisors may now jockey for positions of influence and adversaries should save their schemes for another day, because on this day Crusader Kings III can be purchased on Steam, the Paradox Store, and other major online retailers.


    Real Strategy Requires Cunning

This thread is more than 5 months old.

It is very likely that it does not need any further discussion and thus bumping it serves no purpose. If you feel it is necessary to make a new reply, you can still do so though.

While Waking the Tiger and Cornflakes were not supposed to focus on the naval part of the game, we actually ended up doing a few things anyways :D So today’s diary is going to be about that!

First up: We got a new screen in the Navy Overview Screen that gives you a breakdown of losses and kills. These can be filtered by nations and faction.
Screenshot_2.jpg


You can for example see that France has lost 42 destroyers and sunk 67 Italian destroyers during the last year. The interface also lists convoys, so it’s much easier to keep track on how much of the enemies shipping you have taken out and to see how its changed between current and last month. If you click on an entry here it will give you a detailed breakdown of the ships:
upload_2018-2-7_16-25-18.png


Speaking of convoys: we have changed how raiding works and how losses in convoy efficiency is handled. Convoy sinkings is now tracked by strategic area rather than route, meaning that if several routes go through an area that is being raided, they will all be affected rather than single routes randomly being hit. This makes things much more predictable and you can’t get around efficiency hits by suddenly stopping a trade or a change in supply situation. The actual effect of a sunken convoy depends on how many are active (so if there are two convoys shipping stuff and one gets sunk thats a big impact, but if it’s 50 then it is pretty minor). The efficiency itself reacts slowly a bit per day to avoid jumps and weirdness. This solution means that it’s possible to keep convoy efficiency for the enemy low as long as you raid enough.

Screenshot_3.jpg


To help illustrate this to the owner of the convoys, we color routes that end up with lower efficiency due to raiding orange. Any area that is hit badly enough gets a special texture and is colored red. You can then focus your anti-raiding efforts on these areas.

We have also been tweaking the detection logic of submarines and how fleets engage. Fleets usually had a really easy time to find submarines due to some strange code thats now been keelhauled (a destroyer could more easily find a submarine that could find itself very easily...it was very philosophical), so we hope that part of naval warfare is going to feel better. Naval combat is an area that has been a bit neglected since launch, so we will be giving it some higher priority in future development.

Development wise the team is now in full polish and bugfixing mode, which means pet peeves like this one get addressed. I bet everyone who has played China or Japan has noticed this at least once:
Screenshot_5.jpg


Ships no longer go across land in the Yellow sea (and other tricky places) :)


We have also changed how transports interception is handled. Before it was possible to send a sacrificial transport first, and have it get caught by the enemy fleet as the rest of your transport fleet sailed past to invade the enemy. Now ships in combat are still able to detect transports for this case and “suck” them into the same combat. This should fix multiple exploits :) The way it looks on map (as the later transports may get caught in a different location) is that we show a special combat indicator over them and clicking on that sends you to the main combat in the zone.

Next week we will be taking a look at achievements and nation forming, and some neat new UI changes.

Don’t forget to tune into World War Wednesday at 16:00 CET. Today we are going to start a new session (because Daniel was losing so badly vs Japan >:-D) as historical Germany, to show how it plays differently now.

On the topic of convoy raiding, could we get an alert similar to the naval combat one when our convoys get raided? this is especially bad for nations like Japan that have an expansive island empire where divisions sometimes just get the idea to go on a swim without the player necessarily noticing, thus losing a good amount of divisions

If convoys are easier to intercept then the Allied AI needs to be smarter about not sailing everything through the med (and the Axis through the English channel) on an endless booze cruise.

That sounds like a very nice batch of changes. I'm very interested in how the fix to sub visibility plays out.

Is this naval update included in base game or only DLC?

Looks good, but can you please fix the Air Production continuous focus (right now 20% is way overpowered), let us see allied planes in airzones (right now its blank) and allow allied fighters to escort allied CAS (so one player can control fighters and another CAS for example).
