Alternate download link
Just in case Curse has load issues (as occasionally happens on patch day) I have set up an alternate download page carrying the latest version of my addons. You can find it under http://www.ursbeeli.ch/m_addons.shtml

History
There used to be an addon called RangeHelp by Ralenod which showed the range as a coloured frame in which it indicated, if the player was out of range, in range for ranged attacks, in the dead zone (when it still existed) or in range for melee attack.

It was very useful especially for hunters but really for any character with a ranged attack.

It came with a graphical configuration frame and originally even supported bar switching (though that had been broken in some patch).

With patch 2.4.0 RangeHelp broke the new Combat Log filtering mechanism (at least it seemed to be the culprit as far as I could tell). As it seems to no longer be maintained and as I could not isolate which part of it broke the combat log, I decided to do a semi-re-write of it.

I took its core code, threw out everything to do with the config UI and bar switching to have a minimal code base that would work and did not break the new combat log.

This was fairly easy and worked quickly. I then took it from there to re-add some slash command config options etc.

All credit for the code core goes to Ralenod.

Features
This addon displays a colour coded frame when you select a target. It shows whether the target is out of range (red), in range for ranged attack (blue) or in melee range (green).

Its main use is probably to hunters, but it is also usefull for casters to see when they are in range to attack.
