event moding

[spitfire]

Hi
I am currently trying to do my first mod and i am trying to to do a news event.
I am doing event WW2 and i want it to trigger when germany is at war with major country or poland. But i dont know how to do it. I created the event and everything but I dont not how to make it trigger when that action happens. Can somebody helps?
Thanks

The best thing to do is look at how the original game is coded for events and use this code to help guide you. Start off with just a single short event and get that to work, then you will learn and be able to expand. Do not change the original coding - make a copy to work from.

Thanks for the answer
I already did this. I looked at the original game event (even some modded) and I coded it
It worked when i triggered it via the console. But the problem is to how to trigger it when germany declares war on poland. I looked at the game events (and mods) and I noticed the "trigger" command. So I wrote trigger (and the requirements) and launched the game. But when i declared war on poland nothing happens. I am not sure if this the right command but i didnt find anything else.
So i want to know how to trigger it when this or curtain action happen.
thanks for the reply though

Did you check the console output while you manually trigger the event ? If I remember correctly it should show the requered conditions in details. Maybe you can see what didn't work properly.

Well i'm just a beginner when it comes to modding in hoi4 but i think that's how trigger stuff works.

country_event = {
    id = germany.1
    title = germany.1.t
    desc = germany.1.desc

    trigger = {
        GER = {
            has_war_with = POL
        }
    }

    fire_only_once = yes #up to you

    option {
        name = germany.1.a
        #effect
    }
}

add_namespace = germany.1

country_event = {
id = germany.1
title = germany.1.t
desc = germany.1.desc

trigger = {
GER = {
has_war_with = POL
}
}

fire_only_once = yes #up to you

option {
name = germany.1.a
#effect
}
}

I see you coded it as a "country event" but i coded as "news_event" because i want everyone to see it. Is there a big difference between it?

[Fedmahn Kassad]

Allright, then try this one

add_namespace = news

news_event = {
	id = news.1
	title = news.1.t
	desc = news.1.desc
	
	picture = #picture
	
	major = yes #yes if you want everyone to see
	
	trigger = {
		OR = {
			GER = {
				has_war_with = POL
			}
			any_country = {
				is_major = yes
				has_war_with = GER
			}
		}
    }
	
	option = {
		name = news.1.a
		#effect
	}
}

Plus, just to remind you again

So yes, there's a difference.

Yes a different display but the coding structure is the same. I was showing you what works - the main thing I wanted you to see was - add_namespace = germany.1.

I re-read your post and you are asking about triggers, check out the wikis for full details. Try some trial and error coding, think outside the box, you can learn a lot this way, mostly how not to do something, but it is rewarding when you discover the correct code and the lesson would be well learned.

Conditions

This is a community maintained wiki. If you spot a mistake then you are welcome to fix it.

Conditions (also known as triggers) are used to specify when the execution of effects occurs. When a trigger returns true, then the execution will continue, otherwise it stops. Several triggers, including the default AND-trigger, allow nesting to create more complex expression.

The list of triggers may be outdated. A complete, but unsorted, list of triggers can be found in /Hearts of Iron IV/documentation/triggers_documentation.html or /Hearts of Iron IV/documentation/triggers_documentation.md.

The following video should help, it is possible that some of the things discussed might be outdated but you will lean a lot from them.
