[ue4-archive]

Build info

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

Specs

• 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.

Results

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

Expected

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

Screenshots

Not-playing:

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?

Thanks!

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

Thanks!

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

If you wouldn’t mind, could you create a new post on AnswerHub (in Bug Reports section) and give us as much information as you can?
