TArray Functions .Num() not picking up HiddenWords.h is an Empty Array

Hi,

Been bashing my head against this for a few hours now and just thought I’d throw it to the community and see if anyone else has encountered this problem

I get no errors, but the HiddenWord TArray is empty. When I cursor over in code, it recognizes the data type and compiles no problem, but it’s not picking up the words. It comes in empty and the moment I try to do anything with the array, UE crashes…

Any help? Thanks

Scott

You have declared a member variable called Words which is empty. It’s shadowing your global variable that isn’t. Remove this line.

That’s the ticket. Thanks :smiley:
