***PLEASE READ***

This functionality was removed in a recent patch (2.4.3). It no longer works.

"You can no longer click the minimap to cast ground targeted spells."
***Thanks to everyone for their hard work on this while it lasted - Fursphere 11.10.08***




Not sure if this has been explained but here goes for a refresher.
The following command will ping your minimap at a set location, this can then be used after using a macro to cast say blizzard or any other spell that requires you left click on the floor.

Code:
/cast spellname 
/run Minimap:PingLocation(0, 0)
The first 0 is a horizontal value on the minimap (Min:-69 Max:69 )
The second 0 is a vertical value on the minimap (Min:-70 Max:70 )



Any question I will try to answer.

Thanks to Mudd for this extra information:
To coordinate your clones who may not be facing the right way, you can probably do
Code:
/script local x, y = Minimap:GetPingPosition() Minimap:PingLocation(x * 140, y * 140)
in their macros so they will get the appropriate relative position of where you main casted. You would have to stagger the cast to take into account latency for the minimap ping to make it to the clones. This also means you need to have
Code:
/script Minimap:PingLocation(X,Y)
in your main's macro twice since the first one appears to be gobbled up and never actually pings the map.
