I have them both. They "work" but I can't change the distance. It appears to measure 30 yards. I need it to measure 40. I can't find an option to do this and I don't know what to edit in the .lua or .xml files to change it. If anyone could tell me how to do this I would greatly appreciate it.
I use aUF_RangeCheck_M. It doesn't have an option to change the out of range limit, which is around 28 yards.
Only way to change the limit is to edit the aUF_RangeCheck.lua file. I replaced the aUFR.TargetInRange function with this:
if (IsSpellInRange("Healing Touch", unit) == 1) then
elseif CheckInteractDistance(unit, 4) then
Depending on what class you play and what range limit you want, replace the IsSpellInRange("Healing Touch", unit) check with an appropriate spell you can cast on friendly units.
Note that this only changes the range limit for friendly units (which is all I need for healing). Hostile units and NPCs will still be considered out of range at around 28 yards, which is what the CheckInteractDistance(unit, 4) checks.
