[BUG] Get a reference to self (BP)

Build info

  • Version: 1945001
  • Install Path: C:/Program Files/Rocket


  • OS: Windows 7
  • RAM: 64 GB
  • Graphics Card: GTX 760 w/ 4 GB
  • UAC: Off

Repro Steps

  • Create a blueprint of based on a custom C++ uobject (eg. Inventory).
  • Add an array variable using this type of object (eg. ViewItems).
  • Insert a Begin Play event.
  • Insert an Add Item or Insert Item exec (Call Function → Array → Add Item/Insert Item).
  • Set target array to one created as a variable.
  • Set target item using Get Self Ref (Variables → Get a reference to self).
  • Compile & save blueprint.
  • Do “Play From Here” in editor window.


Array adds a NULL index at end of array (Add Item) or at specified index (Insert Item).


Array adds a reference to self at end of array (Add Item) or at specified index (Insert Item).



Playing - Self reference disconnects, NULL in array:

Work around, not-playing:

Work around, playing - ThisIsAReftoSelf variable does not disconnect, pointer to uobject in array:

Hey Christopher,

Thanks for your report! Would you be able to provide basic code snippet you used to create your custom C++ UObject that is in use here?



G’day Steve,

Forgive my late response.

After more work on C++ class this blueprint is based on, this problem disappeared.

That being said, this is same class that is having issues when I add a new overridable function using BlueprintImplementableEvent ( link text ).

If you would still like to take a look at C++, let me know.

Hey ,

If you could still provide code snippet you are using to create your UObject, we would still like to attempt a local repro to make sure there isn’t anything on our end that needs to be fixed :slight_smile:



I’m having same exact problem using blueprint scripting. Do you still need help replicating it?
