Set location with command

Plz, i need to set the player's (sender) location with a command (X, Y, Z, Yaw and Pitch), and after I need to teleport player with other command...

Example:

command /chain setlobby > Save player's location
command /chain join > Teleport player to lobby

Sorry for my bad english, I researched, but I did not find anything about this, only topics of save location in a .yml file...

 

All you want is a /setspawn and a /spawn command?
If you want to have the location persist after reload or restart you will need to set it to a config.yml.
If you want it per-player, save a HashMap<UUID,Location>

 

When you run the command do these steps

1) save the location in a local variable

2) save the x, y, z, pitch, yaw, and world to config (i always get errors trying to save the actual location object to file)

3) when a player runs the command or how ever you want to use the location, grab the fields you saved to config and construct a new location and teleport the player to it.
