how to save the running game special actors to the maplevel outliner???

I wish to make a game but it’s actually a map designer，This game will have some special rules for placing actors。When I close the game, I want the creation and location of these actors to be save in the project.(Just like dragging from the content browser to the outline view)

so,
In the level blueprint, I made an actor that will be generated in the world after 5 seconds.(use “spawn actor XXX” )
What should I do so that the actor is permanently placed in the world outliner when the game is closed???

thanks!

Hey there @user_2499d193d848d36021dbd3a67cf62df4eee9e18bd8e44a9e8853fc! Welcome to the community! Depending on what level you’re trying to operate on, this has different answers. For example, you can make a level editor system and use Saving and Loading, and replace the actors you’d need on load. This could be tedious if there’s a ton of extra layers to your data, like metadata and customization, but effective if your players aren’t developers themselves. Otherwise you could go one layer deeper like Ark Survival Evolved and have a source build of Unreal that’s modified into a level editor/modding suite for the game. This is more difficult but offers more flexibility for developers to modify the game and work on content.
