Shield Strength

[spoqster]

Hi!

I am looking for an AddOn that displays the current shield strength. Shields such as the Blazing Shield start out with a specific strength and this strength is reduced as the player takes hits. Thus, by taking damage the shield's up time is reduced.

It would be really useful to have the current shield strength displayed on screen.

I suggested the new value on hits to be shown in Combat Cloud, but Garkin disliked the idea and suggested that this may be a better fit for FTC or Srendarr. But these buff trackers typically display run times, rather than values.

So maybe a standalone addon would be the best fit.

Anybody else think this is a good idea?

something like http://www.esoui.com/downloads/info2...tionAlert.html ?
I'm not very skilled in this category, but you should find an "item status" addon, because shield is like whole armor, it decrease wth hits you take.

By default is shield is displayed on unitframes, so what do you exactly want? Some number on the screen or some kind of progress bar?

There is a hack how to get numeric shiled value from the unitframes:

for k, module in pairs(PLAYER_ATTRIBUTE_BARS.attributeVisualizer.visualModules) do
   if module.moduleId == 5 then
      ZO_PreHook(module, "OnValueChanged", function(self, bar, info) d(info.value) end)
      break
   end
end

If you run this code for example using the ZAM Notebook, it will print shield value every time when shield value is changed.

That sounds pretty much like what I had in mind.

The original idea was to have a Combat Cloud style message on screen when the shield is cast that reads "Blazing Shield at 800" and when you take a 250 point hit the text pops up again and reads "Blazing Shield at 550".

Of course having the current shield strength displayed next to the buff is also an option. But it would be a bit of a design exception in the buff context, because an extra value like this is only relevant for few buffs. Also I really like the way Combat Cloud displays information. It's very clear and relevant.

I have written a small addon to test how shields works:
