Need some advice, making a parkour plugin!

So i decided to make a parkour plugin just for the fun of it and i was wondering what would be the most efficient way of getting/saving checkpoints.

I understand you could save there cords to a config file then when the player requests to go back, simply grab them and teleport him/her to it, but would that be inefficient?
I would imagine creating a section in a config file then constantly reaching it when ever a player sets a check point and goes back to it would be resource intensive.
If i'm wrong please let me know, and if someone knows of an easier way to do it, it would make my day if you could enlighten me!

Thanks in advance!

xXRobbie21Xx No, it isn't resource intensive, unless you are like setting a hundred locations a tick, I think one everytime a player requests it is fine.

 

Gerov Allright man, thanks.

 

xXRobbie21Xx you could put them in a hashmap and then save the hashmap to a file onDisable if you needed them to save thru reload then load them back into the hashmap onEnable. i think geting values from hashmaps is more efficient than a config file

 

GeorgeeeHD hmm okay, just to make sure, its possible to use a Location for the key to return? In this case a player uuid

 

xXRobbie21Xx yea you can use anything as the key. HashMap<Location, UUID> or HashMap<UUID, Location> which ever one fits bests

 

GeorgeeeHD Sweet, thanks again.
Really means alot!

Edit: Looks like i checked bukkit at the perfect time
