Direction from player1 to player2 (Vector)

Hey. I had some difficulties with the direction. I want to use a team to get directions from one player to another. That is, the vector, but I can not get 2 days.

thank


P.S.

These arrows from the figure I need to bring the player, but I do not really understand how I need to get them.

 

@ewrs Dou you want the vectors to always depict a certain shape like a square or something? Or are you just interested in the distance of player 4 to 3, of player 3 to 2, etc.?

For the latter one you will just need 3 methods:
Player#getLocation(),
Location#subtract(Location) and
Location#toVector()

 

I want an arrow to tell the player where player 2 is

 

Vector a equals player1.getLocation().toVector().
Vector b equals player2.getLocation().toVector().

If you subtract vector a from vector b you receive the vector from one player to the other player.
The length of this new vector is also the distance between the players.

Does this make sense for you?
