how to select player start?

Ahaaaa, sure you are…

You can use the node “Get All Actors Of Class” and then set the class to “Player Start”.

For example, here on the level start, I get all the start points, and then print their names. You can do whatever you want…

You don’t even have to use the tags, as the tags mostly works with “Components” not full Object/Actor…
