Will you be making a tutorial for interface modding in order to fix the overlap when you make a new ideology, for example?

[@BelaliPasha]

Nice tuttorial

[@conservativedemocracyenjoyer]

Could you be able to do a lesson on using how you can edit workshop content, like map resources? The nudger doesn't seem to like the mods.

[@morasia7976]

Tutorial for making a New map? Would be cool

@The Iron Workshop may you please upload datf file anywhere except steam workshop?

[@DatBoi_TheGudBIAS]

i have an issue. i would like an answer if it isnt too inconvenient. i did my scripted diplo actions, and they work fine. BUT sometimes, or many times in lategame, the AI just refuses to answer my diplo action when i send it. is there a way to make AI ALWAYS answer the diplomatic action, while maintaining the can_be_accepted = yes ?

[@GM-gb1eu]

And i have a question, how to opinion ai_acceptance modifier like in eu4? ( and how to edit existing in-game diplomatic actions) please help

[@DatBoi_TheGudBIAS]

1- use the opinion variable 2- impossible, its hardcoded

[@kennertgarcia3486]

Thank you for this video, i have a question how do you change the position of your new diplomatic action? for example been at the bottom

[@TheIronWorkshop]

All custom diplomatic actions will appear on top of the vanilla diplomatic action, that is not something you can change. What you can change is the order of the diplomatic actions you created by changing their location in the file.

is it possible to modify lend lease? I would like the transport to be shipped faster. I can't find the files of this anywhere

How can I invisible the all diplomatic actions ?

[@brycefoster8547]

Can you add a how to create a faction quick nodding tutorial

[@Fergieluna12]

how would I make it so that the AI only does the action one time? I am having trouble making a "recall volunteers" action for the AI. If they are non-socialist and they have volunteers sent to a country that suddenly becomes socialist, they are supposed to recall them, but they do this over and over and over and it glitches out.

[@mateom3908]

Hey off topic question but do you know where the customtool tip file is locates? I wanted to make a focus similar to the one with new zealand where the uk transfers ships but i cant find the custom tool tip file please help

[@TheIronWorkshop]

It's not a file but a command you have to use, for example: custom_effect_tooltip = "LOCALISATION_KEY_ENTRY" So you put this in your focus/event/decision and the actual effects you put in hidden_effect = { } That way the player will only see whats in the custom_effect_tooltip as the result of the focus/event/decision.

[@mateom3908]

@@TheIronWorkshop ahhhhh, Thank you so much!

[@doktord.8403]

How do you make it show up in the diplomatic window (left next to the diplomatic actions)

[@TheIronWorkshop]

That involves scripted GUI modding which I will cover before the end of the month.

[@hzyoni]

How do you make the diplomatic button turn GRAY after you use and complete the diplomatic action. it stays Green and is re-usable although I already completed the action. I want it to turn gray and unavailable for some time.

[@TheIronWorkshop]

That process is not automatic, you will have to set a country flag on the country that used the button. For example: complete_action = { ROOT = { set_country_flag = used_button } } ROOT = country that used the button FROM = country that the button was used on You can also set it in the visible = {} section to make the button disappear if you don't want it to be visible after being used.

[@pountoun6328]

Hi, if anyone has an idea on what could be the problem : whenever i create an ai_acceptance modifier, whether the conditions are triggered or not, the modifier is visible in the tooltip. What i type is the following : ai_acceptance = { great_power = { base = 0 modifier = { add = -10 if = { THIS = { is_major = yes } } } } } It does work and applies the -10 on majors but still appears as 0 positive for non majors, it does the same for other modifiers when the triggers aren't met.

[@DatBoi_TheGudBIAS]

With my limited knowledge, I would tell the problem is the base = 0, delete that line and test it to see if the modifier applies to majors, and doesn't show anything to minors

[@pountoun6328]

@@DatBoi_TheGudBIAS thanks for the attempt to help but i still can't figure it out 😢

[@DatBoi_TheGudBIAS]

@@pountoun6328 I finished my diplomatic action today and couldn't figure it out as well, I kept 0 as base value, I'll try to figure out some way

[@DatBoi_TheGudBIAS]

@@pountoun6328 ok, im late, but i think i figured. the modifier block is checking for a trigger, so u dont need to put the if, just put this = { is_major = yes } after the add = -10

[@GM-gb1eu]

The Iron Workshop, I have a question, how to create opinion based ai_acceptance ?

[@TheIronWorkshop]

That is actually a tough one and I struggled with it a bit but here's the code I came up which (seems to be working) opinion_checks = { modifier = { has_opinion = { target = ROOT value > 5 } add = 10 } } This checks if the target the DA is aimed towards has 5 or more opinion and if it does adds 10 points to their acceptance. You can change the values as you need.

[@GM-gb1eu]

thank you, you are the best

[@TheIronWorkshop]

Hope it works, from my testing its a bit wonky but works most of the time...

[@Philcoulson918]

Can you force a diplomatic action via a focus? Lets say the embargo diplomatic action?

[@chadofthexxthcentury4741]

yes

What DLC is it?

[@TheIronWorkshop]

That may actually be incorrect since it is possible they were added with a patch that came along with a DLC so you don't need the DLC to work with them.

[@PatriotMapper]

@@TheIronWorkshop Oh, ok.

[@PatriotMapper]

@@TheIronWorkshop I’ve created the diplomatic action, now I need to figure out how I can make it so you can choose a state to get (I’m making a buy state system).

[@TheIronWorkshop]

That is a bit complex to do, you will need to use both arrays and a scripted GUI... There are lessons on how to use both.

[@DatBoi_TheGudBIAS]

@@PatriotMapper ull require a scripted gui. u can make a state selector gui, and then do the changes to those selected states after u send the diplo and they accept
