cast and set target

[upyursh]

hey all, first time poster, first time addon developer

I am going to buy Wow Programming but for now will ask the community for some help

Basically what I'm looking to do is "intercept" a cast of a particular spell and then set the target for the spell.

I will eventually have it so it will cast on mouseover if available, or cast to target, or cast to self

any help would be greater appreciated

i am at work so cant access my wow to test but I have done some ground work.

Am I on the right track here??

I am sure someone else can explain this a little better, but basically this is not possible the way you are trying to do it now. Addons are now allowed to cast spells, CastSpellByName is a protected function.
