Editing WoW:API COMBAT LOG EVENT (section)

=== Simple Function Example ===
Example the following function would display a message whenever a Mind Blast crits.

Foo.xml
 <Frame name="Foo_Frame">
   <Scripts>
      <OnLoad>
         Foo_OnLoad();
      </OnLoad>
      <OnEvent>
         Foo_OnEvent(self, event, ...); -- The ... parameter passes all arguments that would otherwise be implicitly sent prior to 3.0.
                                        -- As of 3.0, you will need to explicitly send these arguments (as done here).  
      </OnEvent>
   </Scripts>
 </Frame>

Foo.lua
 function Foo_OnLoad()
   this:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED");
 end
 
 function Foo_OnEvent(self, event, ...)
 
   local timestamp, type, hideCaster, sourceGUID, sourceName, sourceFlags, sourceFlags2, destGUID, destName, destFlags, destFlags2 = select(1, ...)
   -- Note, for this example, you could just use 'local type = select(2, ...)'.  The others are included so that it's clear what's available.
 
   if (event=="COMBAT_LOG_EVENT_UNFILTERED") then
     if (type=="SPELL_DAMAGE") then
 
       local spellId, spellName, spellSchool = select(12, ...)
       -- Use the following line in game version 3.0 or higher, for previous versions use the line after
       local amount, overkill, school, resisted, blocked, absorbed, critical, glancing, crushing = select(15, ...)
 
       if (spellName=="Mind Blast" and critical==true) then -- ==true for clarity only.  Not needed.
         DEFAULT_CHAT_FRAME:AddMessage("Mind Blast Just Critted!");
       end
     end
   end
 end
