Meaning for ARC in arras.io server template

Anyone knows what is the use/meaning for ARC in turret in arras.io server template?
I tried to change the value, but it seems nothing happened. :no_mouth:

The turret will only shoot if the target is in its arc (Range of fire)

when setting lets say 180 to ARC, that will limit how much of an angle it can turn. Setting the CONTROLLERS with ‘onlyAcceptInArc’ will make it so that the turret cannot shoot if it is asked to fire outside of arc
