Attribute visuals (shields) bug

Garkin · 04/13/15, 09:39 AM

Did you notice that Unit Attrribute Visualizer for shields doesn't work correctly?

You can easily reproduce this bug if you renew two or more shields multiple times - old shields aren't crrectly removed, so your health bar looks like you have permanently applied shield. (Tested with Blazing Shield I + Healing Ward III)

If you take a look into values in PLAYER_ATTRIBUTE_BARS.attributeVisualizer.visualModules, shield value never gets to zero, there are artificial numbers like:
lastValue = 52151
maxValue = -15213
statusMax = 8114 (probably correct)
statusValue = 8114 (probably correct)
value = 52151

I have tried to track shield strength on my own (ShieldInfo addon), but it seems that this is not an UI bug, because event EVENT_UNIT_ATTRIBUTE_VISUAL_UPDATED returns invalid numbers. And also because of invalid shield value events EVENT_UNIT_ATTRIBUTE_VISUAL_ADDED and EVENT_UNIT_ATTRIBUTE_VISUAL_REMOVED are almost never fired (for ATTRIBUTE_VISUAL_POWER_SHIELDING).

Is it really game bug or did I miss something?

Debug info from this code:

Lua Code:

local function UnitAttributeVisual(evt, unitTag, unitAttributeVisual, statType, attributeType, powerType, value1, value2, value3, value4)
   if unitTag == "player" and unitAttributeVisual == ATTRIBUTE_VISUAL_POWER_SHIELDING and attributeType == ATTRIBUTE_HEALTH then
      if evt == EVENT_UNIT_ATTRIBUTE_VISUAL_UPDATED then
         d(zo_strformat("Shield Updated: <<1>>, <<2>>, <<3>>, <<4>>", value1, value2, value3, value4))
      elseif evt == EVENT_UNIT_ATTRIBUTE_VISUAL_ADDED then
         d(zo_strformat("Shield Added: <<1>>, <<2>>", value1, value2))
      elseif evt == EVENT_UNIT_ATTRIBUTE_VISUAL_REMOVED then
         d(zo_strformat("Shield Removed: <<1>>, <<2>>", value1, value2))
      end
   end
end
 
EVENT_MANAGER:RegisterForEvent(EVENT_UNIT_ATTRIBUTE_VISUAL_ADDED, UnitAttributeVisual)
EVENT_MANAGER:RegisterForEvent(EVENT_UNIT_ATTRIBUTE_VISUAL_REMOVED, UnitAttributeVisual)
EVENT_MANAGER:RegisterForEvent(EVENT_UNIT_ATTRIBUTE_VISUAL_UPDATED, UnitAttributeVisual)

Used events:

Code:

* EVENT_UNIT_ATTRIBUTE_VISUAL_ADDED (*string* _unitTag_, *integer* _unitAttributeVisual_, *integer* _statType_, *integer* _attributeType_, *integer* _powerType_, *number* _value_, *number* _maxValue_)
* EVENT_UNIT_ATTRIBUTE_VISUAL_REMOVED (*string* _unitTag_, *integer* _unitAttributeVisual_, *integer* _statType_, *integer* _attributeType_, *integer* _powerType_, *number* _value_, *number* _maxValue_)
* EVENT_UNIT_ATTRIBUTE_VISUAL_UPDATED (*string* _unitTag_, *integer* _unitAttributeVisual_, *integer* _statType_, *integer* _attributeType_, *integer* _powerType_, *number* _oldValue_, *number* _newValue_, *number* _oldMaxValue_, *number* _newMaxValue_)

I have started with no shield active, it was after reload UI, so some values could be present somewhere.
What I did? Activate Blazing Shield, switch weapon set, activate Healing Ward, switch weapon set, renew Blazing Shield, switch weapons etc. until I run out of magicka.

As you can see, EVENT_UNIT_ATTRIBUTE_VISUAL_ADDED and EVENT_UNIT_ATTRIBUTE_VISUAL_REMOVED wasn't fired even once and shield values in EVENT_UNIT_ATTRIBUTE_VISUAL_UPDATED are, ...hm let's say odd. Max value is negative number?

This definitely sounds like a bug.

I also have this problem from time to time. Usually happens in Cyrodiil for me. Only goes away after I relog or crash (which happens a lot more often

).

Confirming this is a bug that I have been dealing with for a long time. The only thing you can do is log out and log back in again. Reloadui will not fix it. Please fix this ZOS!

EDIT:
Champion passives, abilities, and weapon enchants that provide small shields will also trigger this bug.

I added a workaround to my new addon sidWarTools. When you enter /resetshields in chat, it will take the current shield values and subtract them from whatever is returned by the API afterwards.
