Relationship
If the level was created in SuperTiles version before 1.4.5 and SuperTiles Multiplayer before 1.1.6 this field would be null.
If Relationship is equal to null (like in the screenshot above) then every team has no allies and any other team is considered as an enemy.
Create button will help you to create an instance of RelationshipTable class with the mentioned algorithm (no allies, all opponents are enemies)
As you can see in the screenshot above the basic element of the relationship is TeamTag. So to make units allies or enemies you should specify them with different TeamTag. You could look up through example level Square 1, where Team 1 and Team 3 are allies and fight against Team 2 and Team 4 (which are also allies among themselves)
