In retail wow, you can get information from about a unit based on the nameplate.
For example,
would get the attack speed of the unit in nameplate 1 (if this nameplate is visible) and store it in the variable called attackspeed.Code:local attackspeed = UnitAttackSpeed("nameplate1")
However, in the TBC client, it doesn't seem like the nameplate identifiers can be used. Any idea if what i'm trying to accomplish is possible?
