Spawn multiple enemies from the array?

[stiff saffron]

I am working on a top down shooter game, and have a enemy_spawner Node with packed scenes array, which is being filled with new enemies (scenes). Every enemy has a enemy script attached to it.

Enemy spawner script:
var e = enemy_array.pick_random().instantiate()
get_parent().add_child(e)

What I wanna do is, I want to instantiate few enemies of one type at once (to have some alien formations), but I dont know how to duplicate specific scene, or how to refer to the element inside the array of scenes. I have tried:

enemy_array[1] and change the position or even duplicate the Node, also I have tried by modifying the enemy script attached directly to the enemy node, but I receive instantly an error telling me that the Packed scene is null, since its not still spawned or so.

What I also have tried in a first place is much easier option: to make a root node of this enemy and then add few enemies as a sub Nodes like an array of duplicated enemies, but it was hard to fix the area2d and collision shape issues so I have canceled this idea and tought it would be much easier to modify the spawner script only.

Is there a way to change the behavior of each enemy inside the spawner script or I have to make a new enemy script specially for these type of enemies (maybe duplicate the node a few times)? Thanks!

I dont know if i understand your problem well but, you want to spawn multiple enemies from that array at once? If so, you could just wrap that code inside a for loop to spawn as many as you need for enemy in 10 etc. If you want to immediatly do something with the spawned enemies, you can make a new array and add them all to it as they spawn spawned_enemies.append(e). And you can use that array to do whatever you need. In your case e is the enemy itself so you can do things with it right there as it spawns like call a function on it etc.

Yes, but I want to do something with the specific enemy scene inside the array. For example I have 4 enemies inside the array but I want enemy2 inside the array when randomly chosen to be spawned 4 times at once and to have some formation like spawned as circle it doesnt matter, I just want to be able to make modification to the specific element inside the array before being spawned or immediately when spawned.

You only use the scene array to instantiate your objects. The objects are the things you'll be working on, put them formation/groups or whatever.
Your PackedScenes are constants, you don't change anything in them during runtime. They are just there to be instantiated from and that's it.
