API CheckInteractDistance
From WoWWiki
Returns 1 if you are in range of the specified unit to perform the action specified by distIndex (returns nil otherwise).
- Arguments
- (String unit, Int distIndex)
- unit
- The unit to query (e.g. "target", "party1", "pet", "player")
- distIndex
- A value 1-4:
- 1 = Inspect, 28 yards
- 2 = Trade, 11.11 yards
- 3 = Duel, 9.9 yards
- 4 = Follow, 28 yards
- Returns
- canInteract
- If in range to perform the action, 1 (true). Otherwise, nil (false).
- 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.
- There may also be more values for distIndex that we don't know about.
- Patch 2.1 changed trade distance to 11.11 yards, but this was later reverted.
- Example
if ( CheckInteractDistance("target", 4) ) then
FollowUnit("target");
else
-- we're too far away to follow the target
end
