RangeDisplay is a simple range display addon. It is using spell range, item range and interact-distance based checks to determine the approximate range to your current target, pet or focus (if enabled). As of v3.4.1 interact-distance based checks are only used if the other two are unavaliable due to the strange way interact-distance checks work causing strange results with some mobs.
RangeDisplay is a front-end to LibRangeCheck-2.0, a library addon to calculate the range estimates. DogTag also supports LibRangeCheck via the [Range] tag, thus you can get range display in addons using DogTag to build texts, like PitBull (unit frames) and CowTip (tooltip).
Note: RangeDisplay can only check for some specific distances, thus determining a minimum and maximum range to the target. Some of these ranges are rather large, so the range update may be slow, as it takes time to cover a bigger distance. Unfortunately there is no way (that I know of) of providing higher resolution for range estimates.
Options:
/rangedisplay locked
Toggle the locked state of RangeDisplay frame.
While unlocked, you can drag it to a position you like with the left mouse button and open its config menu by right-clicking on the frame.
While it is locked, you can click-thru the display.
/rangedisplay config
Open the config GUI.
Note: the rest of the options changed a bit, I'll update the info soon
Install instructions:
NOTES:
After installing, RangeDisplay will be enabled by default, and unlocked, so you'll see a semi-transparent rectangle in the center of your UI that you can drag to a position you like. After finding a good place for it you should lock the frame with /rangedisplay locked, so that it won't eat your mouse clicks (note: the enemyOnly option only works in locked mode, too).
