Command Of The Sea - Naval WW2 Simulation - Development Log

Hi everybody!

After 3 years of work on our game Command Of The Sea (CommandOfTheSea.com) we’re finally ready to release the first screenshots, videos and information to the public.

Game description cliff notes:

  • Historically accurate simulation of naval warfare during World War 2
  • Global Open World (~360 000 000 km²)
  • First Person Gameplay & walkable ships
  • Celestial Navigation possible
  • Under development
  • Crowdfunding

Details:

1.1 Whole Earth Open World
At first, we’d like to create a digital copy of the whole earth (well, only the oceans and the coastal areas) as a gameplay area. We’ve developed a way to achieve that, and if you take a look at our Screenshots you’ll see that we’ve already been able to reproduce locations of the world with an accuracy of a few meters!

1.2 First Person Gameplay
Then we’d like to be able to command our own ship, and as a player we’d like to be able to interact with our ship from a First Person View, we’d like to be able to walk on the deck, we’d like to be able to command the ship from the bridge, to enter the machine room and to take a good read in our cabin. We’ll start with a Battleship of the Bismarck Class, and add more playable ships as our community supports this.
In a distant future, we even want to make the game playable with a VR Headset.

1.3 Dynamic Weather
Further, we’d like to have a realistic dynamic weather system with low hanging clouds, fog, rain and snow. This is especially important for the time before Radar (or FuMO/RDF) became so dominant in naval warfare. Back then visual sight was mandatory for any engagement on the enemy.

1.4 Celestial Navigation
Additionally we’d like to simulate a correct day cycle, moon phases and star movement for any place on the earth, at any given time between 1939 and 1945. This will allow celestial navigation, so if provided with a sextant & a watch the player will be able to determine his position by the stars (or the sun). The technical problems for this milestone are also solved already

2. State of Development (Sep 2018):

We’ve started to work on this game in early 2016. Since then we’ve heavily focused on solving the most obvious technical problems, to determine if it’s even possible to build this game of our dreams.
As you can see we’ve come a long way since then, and about 95% of the most difficult problems are solved. We’ve built a small (~100 000 km²) digital copy of the world, covering Norway & Germany. We’ve created a reproduction of Sun, Moon & Star movements between 1939 and 1945, we’ve created a playable & walkable Ship (Tirpitz), we’ve created primitive, self-navigating AI Ships and a visual sensor for AI Players and we have a primitive weather & ocean system.
Right now we’re working on a realistic armor piercing model & a first primitive AI for land based coastal artillery.
So we’re confident now that this project is doable if we get enough support from you and our community

3. Tech Demo Release:

We’ve already released our first Tech-Demo in August 2018 (link on our website). Now we’re putting in continuous development to add further elements of gameplay, and to release an updated Tech-Demo every few months for our supporters.

4. Further Roadmap:

4.1 Next Milestone
We’re actually working on a armor piercing model, and a primitive AI for Coastal Artillery. For gameplay we plan to reproduce the battle which on April 9th 1940 around Oscarsborg Fortress/Norway, when the german navy tried to break through to occupy Oslo.

4.2 Following Milestone:
Once land based AI works properly we’ll work on our first real AI Battleship, to allow some PvE Battleship vs. Battleship gameplay.

4.3 Further Milestones:
For further releases we’d like to complete our map for the north & south Atlantic, with elements of the german Kriegsmarine and the British Royal Navy. Then we’d like to expand into the Pacific Theater, with the US Navy Pacific Fleet and the Japanese Imperial Navy. That will also include Aircraft Carriers.
We’d also like to create playable submarines, especially for the German side of the game, commercial surface Raiders (like Atlantis & Thor) a VR game mode, and multiplayer options.
We consider this game as an ongoing project, and hopefully we’re able to create a large enough community to support & fund for the years to come!

Thanks for your Support!

Congratulations, very nice project indeed !

I am also working on a project involving large terrains (helicopter sim/game), I am currently working on flight model and systems and will undertake the terrains soon,

are you going to share more on how you solved those problems ?

I am also studying Houdini for automatic terrain population I thought you might be interested in this very recent development called PDG for populating large worlds.

Anyway I know how difficult and time consuming all you did so far, keep on the good work !

Bye

Fred

Thanks, we’re using a inhouse solution for the terrain generation. Do you want to use a copy of the earth as we do (that’s complicated :slight_smile: ), or just a large “random” terrain?

Oscarsborg Festning April 9th, 1940

Short Story:
At April 4th, 1940 the “Battle of the Drøbak Sound” (Wikipedia) took place in southern Norway when the German heavy curiser Blücher tried to break through to Oslo and was sunk by the 28cm coastal artillery and torpedo batteries at Oscarsborg Festning (Fortress).

In Game:
We’ve implemented Oscarsborg Festning as a “Point of Interest” in Command Of The Sea. These are locations in our open world where we’re using a much higher landscape-resolution and pay special attention to details which involves a lot of “handcrafted” 3D-Models.
At our actual state of development (October 2018) we’d like to implement some AI coastal artillery there, which should serve as a intermediate step towards smart enemy AI-Ships.
Feel free to compare our reproduction with the real location on Google Maps, although some details have changed during the last 80 years, as it’s now polished up as a tourist attraction.

BTW the lights in the windows are dynamic, based on daytime & sun intensity :slight_smile:

Rebuilding Tirpitz with new Armor Plate Model, with realistic thickness

We’re actually rebuilding Tirpitz with new structures that reflect the true Armor/Steel plate thickness of the real Tirpitz, as our previous 3D Model “only” represented the outer shape of the ship.
At the same time we’re constantly testing it against the land based AI Artillery at Oscarsborg

Projectile Ricocheting SloMo

We’ve created a video to show some more details about the projectile impact simulation we’re using. Including some slow motion footage and some insights about our speed of sound implementation.
Hope you guys enjoy it!

Command Of The Sea - Trailer

We had some fun creating a Blockbuster-Style Trailer, hope you enjoy it too! :slight_smile:

It’s a Bismarck!

Ladies and Gentlemen, it’s a Bismarck!

At least in the making… :slight_smile:
We’ve initially applied the camouflage that was used during the Battle of the Denmark Straight following May 24th, 1941.
Although she might not be as appealing as her sister Tirpitz with her Baltic Camo, it’s easily visible that this painting scheme is very effective against a bright horizon in the North Atlantic. It’s a painting scheme for a work horse!

Bismarck Closeups

Today I’d like to share a few more details about the latest improvements we’ve applied to our Bismarck Model.

If you take a close look you’ll see that parts of the previous camouflage is shining through at the hull and the main deck. That’s NOT because we were lazy… :slight_smile:
We’ve used pictures of the German “Bundesarchiv” as reference, like the one at https://upload.wikimedia.org/wikipedia/commons/7/75/Bundesarchiv_Bild_146-1984-055-14%2C_Schlachtschiff_Bismarck%2C_nach_Seegefecht.jpg

https://www.commandofthesea.com/images/20200407/Bismarck_Deck_Camouflage_w1400.jpg

As you can see there the old camouflage is still shining through, the black & white stripes on the hull were hastily painted over on May 21st, 1941 in Korsfjord, and the swastikas on the main deck on the following day (as no more air recognition for the Luftwaffe was needed where she shall go).

We’ve also started to apply a decent “wetness” effect at the waterline, this is only static at the moment, but we do have plans already to make it dynamic so it really is only applied were the hull get’s wet due to the waves.

https://www.commandofthesea.com/images/20200407/Bismarck_Deck_Treadplate_1_w1400.jpg

And we’ve overhauled the surfaces of our decks with physical based rendering materials, a nice looking, slightly worn and at some places painted wooden deck, and a tread plate deck. I really love the looks of it. The only downside is that I’m very unhappy now with the remaining materials on the ship, we’ll have to improve them too sooner or later. But the potential for photo realism is really a great outlook :slight_smile:

That’s it, I’ll go back to work now so you all can play with Bismarck with our next release in Summer 2020!
