In this example you get -1 if the entities are next to each other, you can change the order of the operation like in the example 2 to get the positive number 1.

Formula

<? @entity1.location.get(1) - @entity2.location.get(0) ?>

Analysis

  entity1: hello
  entity2: bye
  
  Input: hello bye
  
  entity1.location = [0, 4]
  entity2.location = [5, 7]
  
  entity1.location.get(1) = 4
  entity2.location.get(0) = 5
  
  entity1.location.get(1) - entity2.location.get(0) = -1

Example #2 Positive Number

In this example you get 1 if the entity is next to the other.

Formula

<? @entity2.location.get(0) - @entity1.location.get(1) ?>
