How to Modify a Wave Scenario to Get Demolishers and Pentapods to Show up

[newplayer12]

First of all, I'm Korean and I can read English okay, but I'm not used to making sentences using English, so I corrected the sentences with the help of a translator, so the grammar, context, etc. may not be natural. If you don't understand, please ask me to explain again

I love playing Factorio and defense games. So I was having fun with wave defense, which is a scenario in Factorio. I'm not satisfied with only Biter appearing in the wave defense scenario, so I'd like to see the new enemies from Vulcanus and Gleba appear later in the wave.

I then modified the map for the harder difficulty level, splitting the map into four squares and giving each planet its own concept and resources to defend with the newly added weapons. The goal is to reach the edge of the solar system (the basic ending of Space Age, translated directly from Korean) with a customized spaceship, as it seems too easy to just shoot at the existing spaceships since we added planetary concepts.

And since it's more of a defense game, all the basic research is done and you're given basic items for each area, and you upgrade them with the points you get for killing monsters, like the original wave defense.

What I wrote above is the goal of the scenario I decided to create.
But this is my first time modifying a scenario in Factorio.
I knew the basics of the program, so I started reading through the Wave Defense code with a friend who knew a bit more about the program and tried to add some new monsters.

So what I can do is create zones and put the right items in each zone.

But I'm not sure where to go from there.

The problem is three

1) I don't know how to get the monsters to come out automatically.
I opened the code contained in C:\Program Files (x86)\Steam\steamapps\common\Factorio\data\base\script to find where the code related to monsters is, and wrote the best code me and my friend could think of.

But then I got an error and it seemed that maybe this map is not recognizing the small-demolisher etc API because it is not related to the DLC by default, in which case how do I make it recognize it?
Or maybe it did recognize it, but the code we wrote was wrong?

2) I would like to have the DLC be a study of new technologies that are included in the DLC, how do I do this?

3)How do you change the game's clear condition from shooting a spaceship to going to the edge of the solar system?


This is a bit of a rambling post, so thank you for reading it
This is my first time making one, so I may have some facts wrong.

How can I solve these problems to create a scenario that meets the goals I wrote about?
