How do I set text from Dictionary (or Array)?

I have a dictionary that stores messages

0: Hello 1

1: Hello 2

2: Hello 3

I want to set text "message" when an event happens...

Basic logic is "messages.setText --> dictionaryName.2" (I realize that is totally abstract, but that is the logic I am after)

Also how would this work from an array:

Basic logic is "messages.setText --> ArrayAt(2)"

I just need the proper syntax. Cheers!

I may have misunderstood your question, but assuming that "0", "1" and "2" are key names in the dictionary, the correct syntax will be:

MessageObject Set Text --> DictionaryName.Get("2")

Similar to get text from index 2 of the array:

MessageObject Set Text --> ArrayName.At(2)

.

You can find these and lot of other very useful expressions if you press Ctrl-F4 while editing any event/action:

Works great! Now to push it further.... How can I pull out a random entry from the array or dictionary...

Logic like so based on your comments:

Works as static: arrayNames.At(2)

Desire this though:

arrayNames.At(+int(random(0,4))+)

//// So the desired result might be:

arrayNames.At(1)

or

arrayNames.At(4)

or

arrayNames.At(0)

I found this for possible solution: construct.net/en/forum/construct-2/how-do-i-18/select-random-variable-array-47277

Basically this:

arrayname.At(int(random(10)))

But you must know the length of your array (i.e. 10)

UPDATE::::: ACTUALLY THE ABOVE SOLUTION IS NOT WORKING FOR ME??????

You don't need the second parameter if your array has only one dimension (height=1).

arrayNames.at(random(arrayNames.width)) will work just as well.
