# How to calculate distance to Fortress

Hi,

Normally the fortress is occupying a 4 x 4 grid with coordinates from 548 to 551 on both axes.

When you want to attack the FF you need to be in attack range (which is 10 spaces from your attack base).

My question is how is that distance calculated?

Is it to a specific set of coordinates from the 16 possible in the FF grid (ie 550:550)? Or to any of the 16?

Thank you

PS: I'm calculating distance using this formula SQRT((Bx-Fx)^2+(By-Fy)^2) where [Bx:By] are the coordinates of the Attacking base and [Fx:Fy] are the coordinates of the Forgotten Fortress
