Air Improvements



Hi everyone, time for this weeks Death or Dishonor and Oak Update dev diary. Today will be all about the improvements to the air warfare coming in the update. Some of you who were at PDXCON this weekend might have had a sneakpeek, but here are the details :) Speaking of PDXCON, I had a lot of fun meeting fans (but yikes my feet after 3 days), and look forward to next years!

Issues with the old system
When we started looking at the air warfare part of the game we felt that there was two main flaws: Transparency and Control. The system only really showed you information over very long time with graphs so it was very hard to understand what was going on and what you could do to improve things. Control wise it was a lot of work to select, organize and move wings around, not to mention having to open lots of airbase windows everywhere.

So what did we do? Check out this screenshot, it shows most stuff we have at once:



First of all we decided to go with something we knew would work well, making airwings behave more like divisions. They are now on the map and you can move them between bases and assign missions in a similar way to divisions and it’s easy to give orders to many things at once. Secondly we made a new air combat interface that should be a lot more helpful and informative. Keep reading to check out all the details...

Air Wing Interface

The air wing interface has been overhauled. The air base window is now gone. Instead, when clicking on an air base, the air wings will be listed on the left, like army divisions would if you selected ground units. We also added the ability to drag a selection box over several air bases to be able to give orders to all of them at the same time.

The list of air wings shows relevant information about the air wing, such as its strength, type and missions it’s currently flying.


Relocating wings to a new airbase is easily done by just selecting them and right-clicking on a new airbase. We’ve added arrows to show that an air wing is relocating and its progress.

Assign Air missions
Above the list of air wings is the mission panel. To give an air wing a mission in the new system, click on the missions icons in the panel, and right click on the target air region on the map.


As before, wings will only fly missions that are suitable to them. This means that it’s possible to select both air superiority and bombing missions with a mix of air wings. The fighter wings will perform air superiority missions and the bomber wings will, unsurprisingly, provide bombing. This change should make it a lot easier to manage orders for several air wings at the same time and reduce the need to micromanage the air units.

Another thing you might have spotted in the first screenshot is that we now have special combat icons in air mapmode. These show by base color how it's going (sorry Germany) but also which side is getting air support, so a green plane with a + means they are getting help from the boys in the air.



Air Combat Window
As you may have noticed, selecting air wings does not automatically bring up the air region window. This is because we have changed this window into becoming the new air combat window.



The new combat window provides information on air combats in the past day, or from the last sortie. The top of the window shows the familiar information from the old air region window, but the bottom shows the new air combat overview.

The overview is divided into air superiority missions, where fighters battle against enemy fighters, at the top and in the bottom half we show you bombing missions and intercepts. This information can be filtered by mission type, and toggled between our missions and enemy missions.

In the top part you might recognize two new icons. Those are for Air Detection. It's such an important value that we felt it best to move from tooltips and show that instead of radar (which is just one of the factors affecting detection). We’ve been rebalancing a bunch of that stuff too, but don't look too closely on numbers as its in progress.

You may also notice that we’ve added some other useful information. A very important stat is the disruption. This refers to air missions that have been forced to divert back to base, for example due to taking damage from intercepting fighters.

Radar
You might have spotted a little green circle in the first screenie also. We've added more visible radar overlays that you can bring up either through a toggle or by hovering over one


Oh yeah, for those who want to see all the new on-map air counter icons here you go:


As is normal in game development you only end up having enough time to do half of the things you planned from the start, so see this as the first step on air improvements as well. More things are sure to follow in the future, but we are pretty happy with this progress :)

Next week we’ll be taking a look at Yugoslavia. See you then!

“Hearts of Iron 4 wields complexity like a swift armor division during the blitzkrieg, allowing it to serve the idea of layered, cerebral, strategic warfare instead of letting it needlessly bog down the experience.”
9/10 – IGN

“It captivates me because—imperfectly, impressionistically, and perhaps a little amorally—it lets me orchestrate the most titanic armed struggles in history, from the fussy economic details to the cut-and-thrust of mechanized warfare. There are other great strategic-level wargames out there. But I have never played anything like Hearts of Iron 4”
8.8/10 – PC Gamer

“For now, after many dozens of hours, I'm taking a break from Hearts of Iron 4. Not because I'm sick of it; quite the contrary, in fact. What I need to do is some serious reading, some careful planning on what my vision for the United States should be in 1936. And when I've done that planning — when I've formulated my character sheet, as it were — I have the utmost confidence that Hearts of Iron 4 will be ready for me to play a role in world affairs.”
8/10 – Polygon
