Step #1: Create a new Actor Blueprint, and rename it to BoxBP.
Step #2: Go to BoxBP Components:
- Add a billboard.
- Add a box.
Step #3: Go to BoxBP Event Graph:
- Add a new variable called “AnotherBox”. Set its type to BoxBP. Make it public.
- Add a new variable called “NeighbourBoxes”. Set its type to BoxBP. Make the variable an array. Make it public.
- Compile, and save BoxBP.
Step #4: Go back to Level Editor, and add 4 BoxBP components to the scene.
Step #5: Click on the 4th BoxBP. From the Default panel;
- Set BoxBP_1 for AnotherBox.
- Add 2 elements to NeighbourBoxes. Set BoxBP_2 for element 0, and BoxBP_3 for element 1.
Step #6: Go back to BoxBP Event Graph. Just recompile, and save (no editing at all).
Step #7: When you come back to Level Editor, you’ll notice that the variables are all reset to None.
It seems that self-referring variables are reset after compilation.
Question: Is this a bug, or a natural outcome of self-reference in Blueprints?
Kind Regards,
