So if i add stuff like the cube or sphere or any other actor from “Modes” i can parent it to an empty actor. But if i add a blueprint to any of those children objects whenever i start it gets unparented and is impossible to parent back (at runtime by dragging it onto it) and is normally parented when i stop. So why cant i parent blueprint actors to empty actors?
I cant use children actors or any other blueprint stuff i just want to make objects move with the parent just like they would if they were child objects of it.
You can parent blueprint actors to other blueprint actors even if they are empty. You will never be able to reparent and modify the game from the editor while running except for a few differences.
If it detaches then there must be some code that causes it to detach from the parent blueprint. You will have to look through your code to see if it does that. Also check for conflicts between the type of actor it is. Are they both movable?
That makes sense as physics can tear apart a parenting connection if the threshold is high enough. I am not too sure about this though, but good that you found the problem!
