Automated updating of API pages at this location, to reflect patch changes, has ceased from 10.1.7 onwards.

Returns true if the player is in range to perform a specific interaction with the unit.

inRange = CheckInteractDistance(unit, distIndex)

Arguments

unit

string : UnitId - The unit to compare distance to.

distIndex

number - A value from 1 to 5:

1 = Compare Achievements, 28 yards

2 = Trade, 8 yards

3 = Duel, 7 yards

4 = Follow, 28 yards

5 = Pet-battle Duel, 7 yards

Returns

inRange

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

Details

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

Example

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