How to reference a scriptable object at runtime

[tough spindle]

I have only been able to drag and drop my scriptable object onto a prefab with public reference (in inspector).

How do I do this at runtime? I tried to follow the docs but having an issue (see below).

As an example:
ScriptableObject archerData = ScriptableObject.CreateInstance(typeof(Archer));
AddToDeck(testDeck, archerData);

Where the testDeck has:
public List<ScriptableObject> scriptableObjs;

Note: Archer exists as a scriptable object, PlaceableData : ScriptableObject (along with Warrior, etc)

Is there a reason you need to do this at runtime?
There shouldn't be a specific problem with creating it at runtime and adding it to a list. You haven't actually said what the issue is here

[wooden lava]

do you want it to save that reference or something? what's the issue

[tough spindle]

I want to have a deck with references to units in a list (or queue) so that when they are "drawn" the drawn card can instantiate its UI/prefab with data from that reference.

So at runtime, if I want to shuffle the deck or swap out the cards, I want to be able to clear/add to this list of data.
My assumption is I want to have reference to this data but not instantiate a prefab/UI card/unit or whatever until it's needed (i.e. drawn or played).

cool, what's the issue though

[tough spindle]

invalid cast error

[wooden lava]

just a sidenote, consider the generic signature for CreateInstance instead

[tough spindle]

Oh I see what I've done. I thought my chain of inheritance led to a scriptable object... it does not.

In that case - how do I take the specific scriptable object, in my case
WarriorSOData.asset

[wooden lava]

anyways, why are you creating new SOs there?

[tough spindle]

I think that's my issue, I'm not trying to

[wooden lava]

if they're existing units that you just add to your deck, you would just have a reference to the existing SO in the list

[tough spindle]

I just want to use the scriptable objects I have, and apply that to the list to reference

[wooden lava]

right, then CreateInstance is not the right path

you would need to have a reference of that somewhere to begin with

otherwise, how would it know what object you want to use

then you'd just pass that reference along to be added to the deck, perhaps through some layers of encapsulation or abstraction

[faint island]

where is this list that you're trying to apply it to? scriptable objects can be referenced in inspector by just dragging it

you could drag them all to that testDeck

[tough spindle]

Okay, I guess I was doing an intermediary step that doesn't make sense because all of my classes either derive from monobehaviour or scriptable objects. Therefore I can't instantiate that list without an object (which a monobehavior needs to be a component).
Thank you

I want to essentially make a queue that mimics say shuffling a deck, which would occur at runtime. So I was confused on the data being referenced vs the objects of that queue. Drag n drop wouldn't work in this sense.

[faint island]

well you need to drag and drop it somewhere if you want to access a specific instance of the scriptable object. Maybe have some central list of every scriptable object that can go in this deck

[wooden lava]

or whatever is responsible for adding this card to the deck, it would need a reference so it can add the right card

I usually load SOs from Resources.LoadAll()
