Checks whether you are in range to perform a specific interaction with a specified unit.

inRange = CheckInteractDistance("unit", distIndex);

Arguments

unit 

String - Unit to compare distance to.

distIndex 

Number - A value from 1 to 4:

1 = Inspect, 28 yards

2 = Trade, 11.11 yards

3 = Duel, 9.9 yards

4 = Follow, 28 yards

Returns

inRange 

Boolean flag - 1 if you are in range to perform the interaction, nil otherwise.

Example

if ( CheckInteractDistance("target", 4) ) then
  FollowUnit("target");
else
  -- we're too far away to follow the target
end

Notes

• If "unit" is a hostile unit, the return values are the same. But you obviously won't be able to do things like Trade.
