Ai modifiers are in common/ideas/BI_ai_modifiers.txt

Hi Bob, I have 4 categories below that I was hoping you could shed some light on from that file. (i) AI CIV FUEL, (ii) AI Front Defence, (iii) AI Supply, and (iv) AI Supply Build.

1. What determines which ‘number applies (ex, 1 thru 80 or 1 thru 5, etc.,)?
2. Why do they all say “always no”?
3. When we see a .5, does that mean 50% bonus?
4. What does each of the 4 really do?

(i) goes from 1 to 80 with fuel cost increasing at each level

### AI CIV FUEL
ai_civ_fuel_1 = {
name = "AI | Civilian Fuel"
allowed = { always = no }
modifier = {
fuel_cost = 4

(ii) goes from 1 to 5 increasing at each level. There is also a AI front attack from 1 to 5

ai_front_defense_1 = name = "AI | Front Defence 1"
allowed = { always = no }
modifier = {
ai_focus_defense_factor = 0.05}


(iii) goes from 1 to 5 increasing at each level.

ai_supply_1 = { name = "AI | Supply Bonus 1"
allowed = { always = no }
modifier = {
supply_consumption_factor = -0.2
out_of_supply_factor = -0.2


(iv) goes from 1 to 3. Increases in level 3 are 1.5

ai_supply_build_1 = { name = "AI | Supply Build Bonus 1"
allowed = { always = no }
modifier = {
production_speed_rail_way_factor = 0.5
production_speed_naval_base_factor = 0.5
production_speed_infrastructure_factor = 0.5

Can I change these to maybe a zero? Will these changes cause a crash. Thank you very much.

Yes, 0.5 is 50%

Ai civ fuel is the civilian fuel mechanic, in a performance friendly way coded for the AI.

AI Front Defence and Offence are not bonuses / cheats, they just affect how aggressive the AI is.

Ai Supply and AI Supply Build literally do what theyre called

They all have allowed = { always = no } for coding reasons

You can change whatever you want, if its gonna benefit your game if detrimental AI bonuses are gone is the other question

You sir, are the greatest. Thank you. PS - I also see the old BICE modifier file. Interesting differences.

Hm? You mean pre NSB?

yes. It is dated 11-23-21. It does not contain the Supply or Infrastructure stuff. It also does not give the big boosts to AI for Coastal Bunker repair, Air Accidents, Military leader cost, ship, tank, and air factories, and something about 'switch speed factor for economy, mobilization, cadet training, and officer training.

Am i mistaken in thinking this BI_ai_modifiers.text no longer exists. I have found all the other locations but their seems to be no file named this in my current location. I am in Hearts of Iron IV/common/ideas

No. E:\Steam\steamapps\workshop\content\394360\1851181613\common\ideas

Found it. Thankyou for your help. Means a lot :)
