Hello,
I currently have 5 objects in my game, 2 of which i randomly want to be destroyed, keeping the remaining 3 as they were. I presume putting them in an array, shuffling them and then selecting the first 2 or 3 to be destroyed or kept alive a good way of doing it. (Might not be!)
I am very new to blueprinting and ue4, so if you could possibly show or explain an example blueprint that would be fantastic.
Thank you in advance.

Aye, this sounds about right. For any number of actors:
This will remove 2. Do note that the size of the array does not change, it now contains 2 null references to actors that no longer exist - handle with care. It’s probably a good idea to check the array size before you attempt to remove an element that may be outside of array bounds. Alternatively, you can do it like so, which is a tad safer:
If you have only 5 objects that you’ve placed in the level, you can gather them manually by selecting them in the world and dragging them to the graph:
and then make an array:
Sorry only just got round to doing this. Thank you very much, helped me out and finally got it working :))
