how to do this?

how do I make the map generate and than teleport to it? also how do you put name tags above the head of a robloxian?

In future, the titles of your questions should be something relevant to what you are asking about. Also, I'd advise asking separate questions in separate threads. You should also explain to us what you have tried so far, what you don't understand specifically about "generating maps" or teleporting - show us that you are actually trying and that you're not just getting us to do all the work for you.

Given that you haven't done any of the above, the answers that I'll give you will be rough and it is expected that you take some time to look into these in more detail on your own.

1. You need to store your Map Models somewhere, like in ServerStorage
2. Use the clone() method to create a copy of the Map
3. Change the Parent property of the cloned Model to workspace

You can teleport players by setting the CFrame of the Torso of each Player to some coordinate in the new map.

player.Torso.CFrame = CFrame.new(positionOfSpawn)

You can put name tags above a Player's head using a BillboardGUI.
