How to create linked list in blueprint ?

Hi,

In my blueprint I would like it to have a variable that is an object of it own kind. In this way each blueprint instance could point to another instance of the same blueprint, and in this way create a linked list on objects. This works ok, until I try to implement an interface that has a function that gives this object as an output.(Which is needed if some other object should be able to traverse the linked list). When I create such an interface, it seems to work, but when I save the project, close down the editor and reload the project, I get an error message suggesting that the project file is corrupted… I have tried this many times, but always with the same result…

Does any one know how to successfully create a blueprint that can be used to create a linked list of objects ?

best regards
Morten

Sadly, using blueprint interface functions with inputs and outputs (instead of interface functions with only inputs) seems to be the highway to corrupting your files. Try working with one send and one receive interface function until they fix this problem.

Thanks… Hope this will be fixed soon…

it’s fixed in 4.2 :slight_smile:

this tread should be marked as resolved… is there a way I can do that ?
