Vengeance (Tanking Specialization)

[yj589794]

Hiya everyone,

I've been looking at writing a small mod to be able to handle the stacking Attack Power buff that tanks get when receiving damage.


Has anyone seen any API calls that could give the current Attack Power increase from this buff?

Scanning the aura tooltip is an option, but I would prefer not to do this.


Thanks

Maybe it's static and you can multiply the number of stacks with sth.

*errr* you don't.

Each time you take damage, you gain 5% of the damage taken as attack power, up to a maximum of 10% of your health.

Maybe UnitAura has a new value as result. You could print all the UnitAura values and see if there is anything valuable in there.

Unfortunately it does not appear to stack in the normal way.

As each 'stack' is based off the amount of damage taken, then the buff value is extremely dynamic.

My guess is that there is a server side calculation, and the client gets told of the new AP value.

Tooltip scanning is a nasty cludge, and I'd prefer to have a nice API call. Unfortunately I believe it will not be that easy

If Blizzard has to do it aswell: maybe some hint can be found in FrameXML/BuffFrame.lua, who knows.

Oh...hmm

So the tooltip is actually done server side.

But maybe there is a new value in http://wowprogramming.com/docs/api/UnitAura that has the numbers.

Hmmm, quick google search brought this up:

New in Cataclysm: local spellAuraDesc = GetSpellAuraDescription(spellId)

which was swiftly followed by this:

Sadly, the last beta removed the single use of this function in the default UI, so this new API might never make it to release, but it allows to get the description text of the Aura related to a given spell. It was used in the Talent UI to get the different Mastery descriptions.

So close to something useful, will have to check if it does still exist.

I've done some testing tonight, and UNIT_AURA does fire on a change of the Attack Power value from the Vengeance buff.

It's fairly simple to read the value by scanning the tooltip, but I would still prefer to have a direct API call to retrieve the value.
I'll carry out some further testing when I have more time.
