How to choose the player start in a single-player game?

Use a Target Point Actor in the outside map where the door of the building would be. Add a tag to the target point to identify it (BuildingA_Exit). Use Get All Actors of Class with Tag (BuildingA_Exit). Get the location transform and use it to spawn the player. Do the same for Building B…(BuildingB_Exit). You can use the same approach for entries…BuildingA_Entry, BuildingB_Entry.
