Hearts of Iron IV - Development Diary 54 - AI

[SteelVolt]

First of all thank you for answering all of our questions. Its really appreciated.
You said there is no way Players can plan (AI) ally battle plans. Then, Is there a way to make AI prepare for war or coordinate with player or eachother?
How do we coordinate attacks with out fellow AI buddies ? Is this something you want to be focus on future or you think Ally AI's doesnt feel seperated with player? Otherwise how do we make D-day possible ?

Player and AI can see allied plans. The AI will generally wait tith executing plans into enemy territory if they share the front with a stronger ally (particularly if it is a player.)
Functionality beyond this are design questions rather than purely AI.

Thanks everyone for a fine day! Great questions and reactions, and hope you all enjoy the game at release (if, of course, you chose to get it.)

The time at PDX is beer-o-clock now, so I am off for the weekend

Groogy did 4% of the work

Quick question about the ai chance modifiers, are they calculated like in CK2 or like they are said to be done in Stellaris?
In CK2 all additions are done first then multiplications regardless of the order they are written, whereas in the Stellaris modding DD they said that in Stellaris they happen in the order they are written.
Which one does HoI4 follow?

Hi Volt,

nice DD. There is one question I do have.
Back in the DD52 I asked about modding in my own fuel (because I am seriously disappointed with thze current supply system)
Asfahr as modding goes we can add a new consumable to units, and add a material to be produced (See here for reference http://forum.paradoxplaza.com/forum...diary-52-modding.920875/page-14#post-21022137 ). The Q I do have now is: Will the understand to produce "fuel" or "medics" from the get go, will there be adjustments needed or is it impossible?

Best wishes and thanks.

Wanting to take out England before looking east I was covering guarding my coast in case the Allies got and D-Day ambitions, as well as making sure my border with Soviet was covered, while putting as much resources as I could towards building up my forces for a naval invasion of Britain. It was then that England and USA managed to overwhelm BOTH the Italian and Spanish coastal defenses and gain a solid foot hold. Sending troops to back my friends up, once they arrived both England and USA had landed A LOT more troops, overwhelming both the Italian/Spanish defenses as well as my reinforcements.

Isn't it nice when you don't have to cross the Channel to finish off an army (or 2)?

Sounds like great work!

Why (particularly if it is a player.)? Does the AI treat players and other AIs differently and if so how?

My clock seems to be missing this number.

Great DD! Thanks a lot for the detailed explanations, quick answers and great work you are doing

Why is Germany antagonizing Finland?

Holy spirit of dev diaries dude, 3 pages of replies by @SteelVolt. Extraordinary really, great job with the DD,AI and replies, lets hope Sealion-ing the Britain is harder in this one

 

[fabius]

Agreed with most many others: Great DD. Sounds like so many good things to look forward to from the AI.

Currently these traits are primarily for country leaders, but I hope to expand on it and it would be cool to do something like that.

AI Generals having nuanced behaviour from their traits would be awesome.

Great development diary, good to see that the HoI4 AI is very dynamic!

Thanks SteelVolt for all of the answers and replies, sounds pretty awesome, can't wait to see it in action!!!! Have a great weekend

The language is our internal scripting language. As was stated in the mod DD and one of my replies here, we are no longer using LUA for scripting.

Gutted... I knew they were taking the Lua code away but I thought they were going to replace it with something other than just the hideously inflexible scripting language (basically just the events language). The issue with this is that you are very limited in how you can format any calculations, in Lua you could basically do any maths you wanted you were only limited by what data you could pull out of HOI and what you could send back. I know paradox always struggled with the Lua code (I won't comment on why), but some mods did great things with it. To then describe this as the most modable game yet seems a bit ridiculous. Whilst in many ways this game looks better than HOI3 it also looks like it is in many ways worse, and that is disappointing.

You can do a hell of a lot with the current systems, the event system is really quite flexible the only shortcoming imo being an inability to achieve certain effects without a convoluted method and most of the times that is just due to there not being a command to do so and that often gets resolved in a lot of cases if you put a suggestion for it to be added.
You can also probably do the basic calculations you will need in hoi4 as I imagine they will have kept the variable system from other games so you can set a country to have a variable to keep track of things or do whatever else you want.

Great DD!

Really looking forward to see the AI in action.

 

[princeseth]

In the last www Daniel conquered half of Europe with Hungary but the other countries especially Germany did nothing ... how is the AI reacts (or doesn't) to ahistorical situations like these ?

So below is a small piece of code I wrote as part of my technology script, and this doesn't even get into iterating through containers holding variable data. We are not in the same ball park here...

if techWeightsArray[1] > 0 then
landBasedSlots = math.max( 1, math.floor(((ResearchSlotsAllowed * techWeightsArray[1]) - landBasedCount) + 0.5 ))
if landBasedSlots > LandLength then
landBasedSlots = LandLength
end
LandTech = ResearchTech(ministerTag, ai, LandTech, landBasedSlots)
ExtraSlots = ResearchSlotsNeeded - landBasedSlots
LandLength = LandLength - landBasedSlots
end
