Getting a players last location

Hey guys,
I ran into some trouble making a /back command like in essentials. All I want it to do is like log the players last location, due to death, tp, etc. I looked in the essentials code and it has lots of user.getLastLocation(). I was wondering if anyone had a solution to this.. Also my variable for player is player.. Pretty simple, I'm not sure if I need to create a ondeath event or on teleport event for the player and then log the information or something. Any help is greatly appreciated!
Kind regards,
Dylan.

 

Make a HashMap with players name and location, when PlayerDeathEvent is triggered save location to hashmap <konkz, *Location here*> and when /back is used just retrieve the location that is appropriate to the name.

You can then also do /back konkz which would send you to last saved location of konkz.
