Trigger for Neighbor System

[Coffeecool]

So i want to check if a neighbor system is_inside_nebula because i want my Home system spawn inside or close to a nebula.

I did this:

neighbor_system = {
        distance = { min = 1 max = 50 }
        trigger = {
                    planet = {                                                  
                            is_inside_nebula = yes
                    }                  
        }
        initializer = "neighbor_nosferatu_first_colony"
    }

On game start it has no errors, so the syntax seems ok.
But when i start a new game i get this:

[11:16:02][trigger_impl.cpp:577]: Script Error: Invalid context switch[planet], file: common/solar_system_initializers/nosferatu_prescripted_species_systems.txt line: 247, Scope:

}

    }

        id=512
        random={ 582900867 582900867 }
    }
    prev={

        id=512
        random={ 582900867 582900867 }
    }
}

I have no idea what is wrong

Btw "planet" seems to be the only scope that works in this case, without getting a "wrong scope" or "cannot find" error

I think your 'planet' needs to be 'any_planet' for it to work.

It doesnt create a error, yes. but doesnt work.
There is no custom neighbor system inside a nebula near me.

hm, i haven't looked too much at how the system initializers work. I poked around in the initializers files, but the only example of a triggeri could find was an ethos dependant one for the fallen empires. So i'm not sure if it's possible to force it to spawn close to a nebula.
Have you looked around the workshop for anyone doing something similar, maybe you can take a peek at their code?

 

[Coffeecool]

No i found nothing similar, only reason i believed that this should work was the example.txt file.

#this is where the tree part comes in in 'Initializer Tree'
    #Each initializer can have any number of child initializers scripted with in a "neighbor_system" body
    neighbor_system = {
        #The game will test all systems within the distance limit
        #untill it finds a system that fulfills the trigger ( see below ).
        #it will do this in a nearest-first order
        distance = { min = 10 max = 100 }
     
        #if the trigger is left empty it will always succeed. The first closest system that is within the distance limits will be picked
        trigger = {
            #scope = galactic_object ( parent ). root = root gal obj. prev = closest parent. prev prev = grand parent...
            #check stuff
        }     
     
        #finally the initializer to be used for the picked system
        initializer = "example_neighbor"

Ah, but i know what you mean.
It doesnt change postion or creates something if the trigger fails to find a system in range.
It just silently fails.... not cool

 

[Zednosius]

hmm.
Do you know if it's possible to put a trigger inside whatever spawns your home system?

I think what's happening is that it places your home system somewhere, which may or may not be close to a nebula. Then it checks for neighbouring systems within a distance of 50 if they have any planets inside a nebula. If you didn't happen to spawn close to a nebula it would run through all the nearby systems without finding one, since the distance basically puts an upper bound on the number of systems to loop through. I should maybe note that i don't actually know if this is how it works, but it would make sense given what's going on.

My thoughts aswell. I think thats exactly how this all works.

1. create Galaxy
2. randomly spawn systems
3. check for neighbors in range and change them to the desired ones.
4. done

I think the spawning part itself is hard coded, i saw a lot of people complaining that there is no way in influencing the spawning mechanics.

I just had the impression that you could atleast influence the spawning of your neighbors, but they dont "spawn" at all, it seems.

So, you are checking for a planet whose system is within a nebula, that is within distance 1 to 50 of the original homeworld? How many test runs did you do? it seems the odds of a homeworld having a neighbor in that close of range being inside a nebula are slim.

I've been working on this myself quite a lot for my mod Sol Unleashed, and my experience is the same as yours. I did put in a mod suggestion about giving us more control over the spawn positions of system initializers.

So i want to check if a neighbor system is_inside_nebula because i want my Home system spawn inside or close to a nebula.

Would it be possible to avoid all that mess by just spawning a nebula next to your home system and be done with it?
