IMPORTANT NOTE

Sadly, Mythic has removed one of the functions that was essential for allowing hovercasting to work to its full capability in the 1.0.6 client patch. Thus, HoverCast will no longer be functional once the patch is live. If at some point in the future an alternative means is provided that allows me to implement mouseover casting, I will update HoverCast to use such means; until that time, consider this project discontinued.

Yes, there are certain workarounds that could maintain a small amount of HoverCast's functionality, but they lead to a rather sluggish and awkward feel (and aren't adequate to maintain the kind of range-checking ability that made HoverCast so much more useful in combination with Squared) that I don't believe is useful enough to continue updating HoverCast at this time.

About HoverCast

HoverCast enables mouseover casting of friendly spells for the default player, group, warband, and scenario frames. It also supports mouseover casting for Squared UnitFrames.

ADDED in 2.1:

• HoverCast now has 3 different modes in which it will operate.
• To set the mode, use /script HoverCast.Mode(#) where # is either 0, 1, or 2.
• To view the current mode, just use /script HoverCast.Mode() with no number.
• Description of modes:
  • 0 = No special target management when mousing over unitframes (Equivalent to version 1.7.1 behavior).
  • 1 = Will automatically target the moused-over unit when hovering over compatible unitframes, and then restore original target when the mouse is no longer hovering over a frame (The new default in 2.1+ version).
  • 2 = Will automatically keep the friendly target set to self when hovering over compatible unitframes, and then restore original target when the mouse is no longer hovering over a frame (Equivalent to version 2.0 behavior).
