Reference a specific instance of an object in expressions

For example, if I want to spawn an object in the area in the middle of two sprites:

But how can i make reference to specific instances here?

Some pick condition.

x= random(object(0).x,object(1).x)

Asuming the pickconditon only puts 2 objects in the Selected Objects List.

Thanks for the answer!

Unfortunately, I can't understand what your suggesting.

My real doubt is about the possibility of referencing a particular instance of an object just in the expression, without conditions.

Yeah.

x= random(object(0).x,object(1).x) <--------------- translated

object(nth).expression

Where nth is the IID in a SOL. No SOL, ...NO meanigfull IID. No pickevent no SOL

Now answhering again the 'here' in your question:

Some pick condition.

x= random(object(0).x,object(1).x)

Asuming the pickconditon only puts 2 objects in the Selected Objects List

Or did you post that image just to confuse poeple ?

99Instances2Go

Yeah, sorry

I wasn't clear enough.

But now i got it! I didn't know about this "(instance number)" after the object name hehe

Thank you very much.
