Creating Multiple Instances During Runtime for Efficiency and Organisation

Basically, you need to "mark" them in some way, so that each of your instances has some "ID" that makes it unique.

If you create objects in runtime, you can give them an ID directly upon creation:

i.e.

on loop "create_label"
>>> create "label"
>>> set "label" ID to loopindex("create_label")

If you have your labels already created in frame editor,
another simple solution could be:

run this event once
>>> spread value 0 in "ID" of label

Both of these will assign each of them a unique "ID" from 0 to 5 (since there are 6 of them)

then each time you want to reference a specific instance,
you simply add a "filter" in the condition,
say you want to address label 3:

(your triggering action)
+"ID" of "label" = 3

Yes - sorry,
I was talking about tagging "ID" an alterable value of the "label" object X)

Your labels are string objects?
You can still use them, i.e. you can store their "fixed value" as ID in a reference table,
you could use global values for this, or an object's alterable values or a list object

i.e. using an object's alterable values to store IDs (let's call it "my labels")

run this event once
>>> start foreach loop on each one of "string"

on each one of "string"
>>> set value foreachloopindex("string") of "my labels" to fixed value of "string"

this will populate your first 6 alt. values of "my labels" object with fixed values of your strings

then to pick a specific label:

(your triggering event)
+ pick object with fixed value = (AltValN xx of "My labels")
>>> do stuff

where "xx" is your label number from 0 to 5

ehm, also consider you might have far simpler options, depending on your game / personal preferences

i.e. if your strings are static, you could pick them by position

(on triggering event)
+ pick all objects in a zone
and set a zone around the string
(this is a condition inside the "new objects" element)

or you could make "pointers" over each label,
like object 1 placed over string 1 and so on

and then:

(on triggering event)
+ object 3 overlapping string
>>> do stuff

will pick the string overlapped by the specific object
