This is the first release of the simulation.  Lets discuss bugs and things you want to see added to it.

(+1)

Anti-Ballistic Missile systems (THAAD, S-500, whatever) would be neat.

Developer

I will probably add ABM one day but it is rather difficult to model realistically and in reality it is so unreliable that it will have very little influence on the results.

(+1)

What could be the possibility to implement "automatic" interception animations that deteriorate the cluster at whatever respective phase of the ICBM launch cluster consists of, by look up tables for ABM exercise data?  That way it would (at least) operate on the statistically realistic side of things and perhaps be faster to implement?

Developer

It should be relatively easy to build some kind of statistical ABM, but I am not sure how realistic it will be. There are so many factors that are influencing the interception rate, which will be very small in the end.

 

  • U.S Faction
    • Minuteman III speed (terminal speed 7826.66667 m/s), accuracy/ circular error probable (240 m), mirv radius, apogee (11,000,000 m) and range (greater than 9,700 km) may not be correct. Can also carry up to 3 warheads and only can carry W87-0 or W78. Though New Start limits to one warhead
    • Trident II speed(terminal speed 8,060 m/s), mirv radius, and range (more than 12,000 km reduced load or about 7,600km Full load) may not be correct. Also can house up to 14 w76-1 or w76-2 or 8 w88. Due to New START in practice each missile carries 4 warheads
    • AGM-86B range( greater than 2,400 km or 2,400,000 m) may not be correct. Can only carry one W80-1
    • Nuclear weapons yields are correct.
    • Ohio Class subs can spend a lot longer than 30 days off base/only limited by food speed (37 km/h) way off. Also can carry 24 SLBM but limited to 20 due to NEW START
    • B-2A speed (cruise speed 900km/h), range (11,000km), and altitude (ceiling 15,200 m) may not be correct. Can carry 16 B61 or 16 B83
    • B-52H speed (844 km/h), range (14,080 km), and altitude (ceiling 15,200 m) may not be correct. Can carry 12 AGM-86
    • F-35 speed (max 1,296 km/h), range (2,800 km), and altitude (ceiling 15,200m) may not be correct. Only one B61-12 
    •  F-16 speed (1,482 km/h), range (4217 km), and altitude (ceiling 15,200m) may not be correct. Both B61 and b83 2 only for both
    • Tornado speed (1,482 km/h), range (3,890 km), and altitude(ceiling 15,200 m) may not be correct. Can carry 4 B61’s

 

  • Things I would love to see added/ Explained
    • Other Factions fully implemented, China, North Korea, Iran, ECT
    • Where can we get the KML files to populate with real bases/everything?
    • Also, I cannot get aircraft's gravity bombs to work properly can you make a video how those specifically work?
    • Where do you get the information for this simulator both nuclear and military craft?
    • Have the ability to, since this is a simulator, see the past effects of nuclear accidents and detonations.
    • Conventional Naval vessels
    • Have in the future ABMS, and be able to the what the effect of countering both bombers and submarines would have using convention weapons systems.
    • Possibly be able to tune this simulator into a DEFCON similar game.

Also, if you would like assistance on getting values for military equipment I am willing to help. Like yield, range, speed, mass, ect.

Developer

Oh wow, thank you for the detailed review and suggestions!

Many values are definitely incorrect. My main concern were the humanitarian effects. If you want to create a realistic database yourself, the ideal way to do it is: create the database, pack it into a zip folder and upload it onto the mods website: https://nuclearwarsimulator.mod.io/

This way, everybody else will be able to easily use your database.

(1 edit)

About the KML files where do we find those I saw in the youtube file explaining it you had some so. Also gravity bombs I cannot seem to get to work are they fully implemented yet? If implemented could you do a short youtube video showing how to use them?  I am also willing to assist on this project if you would like sir, I have some Unity experience and am currently enrolled for networking and cyber security in the USA.

Developer

For the KML files you can start here:

https://fas.org/programs/ssp/nukes/_images/CentralChina.kmz
http://nuclearforces.org/kmz/NewSTARTRussia1Sep2012.kmz
https://drive.google.com/open?id=1duWEZUGj1dRHuRM80AbT-VGzv4KbxjlE
https://drive.google.com/file/d/1pDYRHjOjbyVJUHmBS56O9tfFPan78DWU/view
https://www.ausairpower.net/Google-Earth/SovietandRussianICBMs.kmz
http://www.mediafire.com/file/tb1wyfw7izfl8py/US_ICBM_Sites.kmz/file

Or just google for specific object type and KMZ.

And here is the video on how to use them

It would be difficult to assist me with the simulation directly. I think realistic datasets and scenarios are what the simulation lacks most right now. Later, I hope to introduce script modding so you can go wild there.

Could you make a road map or list of what you plan to add to this simulator?

Developer(+1)

I probably should make a trello board with the roadmap.

Would greatly appreciate that. I am going to be sending you an email about this so please do not delete it, it will be from a gmail address.

Developer

Great. Thanks!

could uadd a mega.nz link or Utorrent link i keep downloading and it keeps failing i really wanna play it :}

i suggest you add something like making a custom missle where you can design the shape of it and the shape of it affects the damage it does or the accuracy of it

Developer

Making the missile design process a little bit more interactive is a great idea. However, the shape of the missile usually has little effect on the characteristics like accuracy or yield.

(+1)

This is really great...I've found a bunch of performance bugs and also rendering bugs through running it, however.  I'm an experienced unity developer and performance engineer for games...is there any way you could consider releasing the code for this on github so you can accept patches and changes directly?  Even if you don't do so under a truly open source/permissive license, I'd still submit performance enhancements and bug improvements.

Developer

Thanks! You are right, there is a lot of optimization to be done. One issue I am struggling with is the performance drop when rendering a lot of lights on weak hardware. I will probably make so of the code open source (like the effect codes), but not the entire project. Please let me know where you find most significant performance issues and I will try to fix it.

Hello, I have downloaded this game  and followed the instructions, however when I launch the exe file or the application file labeled Nuclear War Simulator with the Unity symbol as the icon, nothing happens the application is able to be seen and ended through task manager which says it is running but nothing comes up and the appliaction is shown only using memory and nothing else and nothing ever pops up on screen and the game never actually opens and starts, I was wondering if you could provide any support on this issue, as maybe you have seen it before and know the cause, thank you for your attention.

Hi Josh, I am very sorry to hear that it doesn't work at all for you. Can you send me your hardware stats and your Player.log file from C:\Users\<your user name>\AppData\LocalLow\Ivan Stepanov\Nuclear War Simulator to my email ivan.stepanov.nws@gmail.com?

Also you can try to start the simulation by right-clicking on the exe-file and select "Run with graphics processor -> High-performance ..."

Where is this option under right-click? I have the normal options and the only one close to what you were saying is the Run As Administrator option which also does not work.

Developer

Do you have Windows 7? If so you can try to select the defauld graphics card in your NVIDIA Control Panel. What is the model of your graphics card?

i have gt 630 isit enough

Developer

I'm not sure. GT 630 may be too old. Just download it for free and let me know how it goes.

i cant play it cause it keeps failing could u please upload it on mega.nz its free i really want to play it you know if u upload it on mega pls reply the link

i downloaded it once, tried to extract it, f*cked it up because i closed my laptop, and had to redownload. the second time, the download failed because the browser crashed. the third time it worked perfectly, other than that it took way too f*cking long to extract. after all that, the first time i ran the game, it crashed while telling me about MIRV's. the second time, i was so confused  about what to do so i clicked the play button to see if any tooltip would tell me what to  do once the game started playing. but then there were just missiles flying all over Europe. then i realized they were flying all over the world. Who's at war with who? how can i tell? i found a button next to the play button that let me make a bunch of nuclear explosions so i just started clicking on cities in russia. after a while i guess i was trying to figure out how to place a base i saw a button that said something like "calculate casualties" a few seconds after i clicked it, the game crashed.

TLDR: I f*cked up the zip extraction, then the download failed, then the extraction took forever, then the game crashed, then missiles went flying, then i made explosions all over russia, then i tried to calculate the casualties, then the game crashed.

Developer

Hi Tommy, wow thats a lot of problems in one place.

Long exraction time is a known issue. The reason is a larg number of map files. I have to solve it one day.

It is weird that it crashes when you press calculate casualties. Can you tell me your system specs and send me your Player.log file from C:\Users\<your user name>\AppData\LocalLow\Ivan Stepanov\Nuclear War Simulator to my email ivan.stepanov.nws@gmail.com after a crash?

Could you create a change log that says what has changed between versions before downloading?

Developer

Yeah, I should do it. You are right. Thanks!

Could you try for an upload to steam? that would be great

Hi Ivan, I really appreciate your work.
May I suggest to implement Aircraft Carriers and Air to Air Refueling? This will really improve the simulator since all fighters lack the range to  accomplish long range missions.

Developer

Thanks! I'm glad to see that you like it.

I will have to add aircraft carriers at some point, but I am not planing to add refueling. Refueling would introduce too much complexity into the simulation. You can account for refueling by simply including it into the range of the aircraft.

How's that Linux port going? I am currently running this on a embarrassingly weak laptop, so I was also wondering how to change the graphics settings.

Thanks,

Kinnetic

Developer

Little progress on the Linux port ... :(

You can find graphics settings on the left side of the screen, but the only setting that will help you with performance is the number of explosions with lighting animation. What is your hardware? Are you having serious issues with performance?

(1 edit)

Hey no problem, I'm on the verge of a hardware solution that will let me run "Windows" under Linux. The laptop I'm running this on is a Latitude 3180, so it's pretty weak. But I'll paste specs here:

             Machine name: private
               Machine Id: private

                Page File: 4109MB used, 1412MB available
              Windows Dir: C:\Windows
          DirectX Version: DirectX 12
      DX Setup Parameters: Not found
         User DPI Setting: 96 DPI (100 percent)
       System DPI Setting: 96 DPI (100 percent)
          DWM DPI Scaling: Disabled

        Manufacturer: Intel Corporation
           Chip type: Intel(R) HD Graphics Family

In other words it's a potato. Anyways, maybe making draw distance for details or more detailed lighting settings?

Thanks,

Kinnetic
