How to make ue4 remember world placement order?

Development Programming & Scripting
1

So I have an actor parent blueprint with a child… within this is an exposed variable which is basically an integer labeling order of the child (1,2 3 etc) I place these child’s in the world duplicating as I go, place in a specific order within the world. My coding works great as it is very important these child’s are in the right place and order for it to work.

However if I exit unreal engine and reload my project… all my child actors are still in the world all in the right place… but no longer in the specific order I originally placed them… It’s like the engine doesn’t remember the order in which I placed these actors when it has loaded up my project again… (3,1,2) instead of (1,2,3) how do I avoid this and tell the engine to just remember the order in which I’ve duplicated my child’s within the world.

Any help would be greatly appreciated,

I’m not sure exactly how you’re placing those children, but I think you need to use a save game to remember the indices.

Whether you’re placing them with the construction script or at runtime, you have can use a save game to remember which child has which index.
