I'm trying to make a simple text output of my current spell power value. I've created a text aura with %c value and this custom function:
Code:
function(school)
local schools, spellPower = {'physical', 'holy', 'fire', 'nature', 'frost', 'shadow', 'arcane'}
local GetIndex = function(table, value) for i,v in pairs(table) do if v == value then return i end end end
if school and tContains(schools, school) then spellPower = GetSpellBonusDamage(GetIndex(schools, school)) else
local holySchool = 2
minModifier, holySchool = GetSpellBonusDamage(holySchool), 2
for i=(holySchool+1), MAX_SPELL_SCHOOLS do
local bonusDamage = GetSpellBonusDamage(i)
minModifier = min(minModifier, bonusDamage)
spellPower = bonusDamage
end
end
return spellPower
end
It works quite well immediately but only when my WA2 settings window is open. I figured I need to create a trigger (I thought that wasn't necessary if I wanted my aura to be always visible). I've tried for a couple of hours now, different combinations, but I can't satisfy all my requirements, which are:
1) Display my text aura always
2) Update it when my spell power changes
3) Don't update on every frame, only on spell power changes
Can anyone help me figure out the trigger(s) needed for this?
