Most of my code is in C++. I subclass my C++ classes to configure the values using the Blueprint editor.
I use Class Default Objects (CDOs) extensively, because I just need a place to put the configuration and I want to avoid the overhead of creating/destroying objects.
I’ve run into an issue where using a Blueprint custom event causes the game to crash:
I thought it was due to my modifying a variable in the Blueprint code, so I removed that and made the class Const, but the crash is still happening.
The GC object that’s having issue seems to be the function itself. This is the log:
Disregard for GC object Function
is not part of root set
I don’t fully understand how there could be garbage in this case, as no variables (local or otherwise) are used. It seems like any value that is accessed can cause a problem, even if it’s not explicitly stored.
The conclusion is that it’s not possible to run Blueprint code using the Class Default Object’s pointer. Is this true? Am I interpreting this wrong?
