Target target targeting my target

[vor_lord]

Even if the code is a little down-and-dirty, I'd really like to see the algorithm you use. I'm curious, and I have an idea for an interesting mod. Even if you don't post it in the UI forum (although I think lots of people would love it!), would you consider posting at least the targetting code it here?

Ok, here it is. I still haven't used it on an honest-to-goodness instance run, but I think it works pretty well (now that tab targeting works). Friday night after our Zul'Farrak run I will put it up for download.

Any good ideas for a name? I called it AggroHelper but that isn't informative or interesting.

Edit:

I forgot to mention that I will credit Ravage with the idea for the mod. Do you want to be credited as Ravage or something different/more specific?

Code:

-- The real work of the mod
function AggroHelper()
 -- If disabled, don't do anything
 if ( AggroHelper_disabled ) then return; end
 local orig_target = UnitName("target");

 if ((orig_target == nil) or (UnitIsEnemy("target", "player"))) then
   return;
 end

 local cur_enemy_target;
 local cur_enemy;
 local i;

 AggroHelper_Debug("Aggro Help for " .. orig_target .. "!");

 for i = 1,AggroHelper_target_search_limit do
   TargetNearestEnemy();
   cur_enemy = UnitName("target");
   if ((cur_enemy == nil) or (UnitIsFriend("target", "player"))) then
     AggroHelper_Announce(" **  No enemy targetable  **");
     break;
   end
   -- We have found an enemy within range of the function.  Now "assist" it
   AssistUnit("target");
   cur_enemy_target = UnitName("target");
   AggroHelper_Debug(" --- checking " .. cur_enemy .. " : " .. cur_enemy_target .. " ---");

   if (cur_enemy_target == orig_target) then
     -- We have found a match!  Target the last enemy, it should be the right one.
     TargetLastEnemy();
     AggroHelper_Debug(" ** selected " .. UnitName("target") .. " **");
     return;
   end

 end

 -- If we reach here, after AggroHelper_target_search_limit tries, we couldn't
 -- find a suitable candidate.  Target our original target again, as that
 -- seems to be the least surprising thing to do.
 AggroHelper_Announce(" ** No enemy found targeting " .. orig_target .. " **");
 TargetByName(orig_target);
end
