Solved Teleporting the player 1-2 blocks behind an entity based on location

Hello! I tried to be as specific with my title as possible. I am trying to teleport the player 2 blocks behind an entity based on where the player and the entity are located, in a way swap what side you are on of the entity. I was able to do the first part, teleporting the player to the opposite side of the entity, my question is how can I make it a fixed distance of 1 or 2 blocks (depending on how far back I want to be). My code for the teleporting to the opposite side of the entity:

Code:

//player being a player variable, and e being the entity variable of course
Vector v = player.getLocation().toVector().subtract(e.getLocation().toVector());
                    player.teleport(e.getLocation().add(v.multiply(-1)));
                    player.teleport(player.getLocation().add(0, e.getLocation().getY() - player.getLocation().getY(), 0)); // I also wanted the entity and player on the same Y level

If the player is 3 blocks away when using the above code, they will be teleported 3 blocks away on the opposite side of the entity, I want to make this a fixed distance of 1 or 2 blocks at any distance. Any help is much appreciated!

normalize the vector and then multiply it by 2. This should make sure it will always two blocks away.

 

Thank you very much! That worked like a charm! I thought the solution would be similar, I forgot about normalizing the vector though. Thanks again!
