Problem with adding elements to an array.

Development Programming & Scripting Blueprint

Hi,

I just played around with some Blueprint stuff and have the following problem:

When I add an element to an array “directly”, that is: in the event graph, it works:

In the game, the array gets filled:

**But: ** When I do this inside a function, the array does not get new elements added :frowning:

What am I doing wrong here?
The function looks like this:

But all I get in the game is:

Why is this not working :confused:

Any help is appreciated :smiley:

Hey Klaus,

This is your alter ego from tomorrow. :smiley:
I just found out whats wrong.
You need to either mark the function inputs as “passed by reference” and not by value (as it is default),
or, you put a “set member” node after the function call and thus explicitly replace the data.
