How do I access a variable from an array?

I have an array of Objects, and each object within that array has a variable called “Homebase Tile Currently Selected” – what I want to do is go through each object in the array to see which Object has the “Homebase Tile Currently Selected” currently set to True. But I can’t seem to figure out how to access the variable. I feel like I should be able to access it through the Array Element pin, but don’t know how to get there. Any advice?

Avoid placing down orphaned nodes like you did with the boolean. If you feel you must do this, something has already gone wrong.

  • either the array is of the generic Actor type only - can you confirm its type? Hover mouse over that array variable, what does it say? Is it the type you need? It should say this:

  • or the ForEach node outputs undesired type - note that the order in which you plug in wires into nodes may occasionally matter and the object type a node spits out on the other end will change. This macro is a good example.

Okay, this is what I get when I mouse over the Array input pin:

What I did to make the Array was to make the array on BP_BasicGameboard blueprint, and then assign the elements in the UI of the Level:

Now, the tiles in question are child objects of a parent class, so I should switch the Array type to be that of the parent class? Then I would be able to access that boolean within?

I meant the array variable itself. If it’s of the correct type, disconnect and reconnect the loop - it will inherit type from the var.

Sorry – is this what you meant?

So this means that it is the generic Actor type, then, correct? And I would need to change its type?

Exactly, ideally to the base parent class of whatever you want to hold inside. As in:

Yep! That was it! Thank you! I had tried changing the Array class before, but did not disconnect and reconnect; this worked!

Yeah, any node with a grey wildcard pin will inherit type. You can also right click some pins to change their type.
