Need help with lua for custom trigger

Guides UI and Macro
1

Hoping to get a little help because I’ve been struggling with this one for a while now.

function()
local region = aura_env.region
local plate = C_NamePlate.GetNamePlateForUnit(“target”)
local start, duration, enabled = GetSpellCooldown(“Shield Block”)
local defend = UnitAura(“player”, “Defensive Stance”)
if plate then
region:ClearAllPoints()
region:SetPoint(“CENTER”, plate, “CENTER”, 84,0)
if duration == 0 then
region:Show()
if defend then
region:Show()
else
region:hide()
end
else
region:Hide()
end
else
region:Hide()
end
return true
end

Adding the defend variable and placing a dependency on it to show the region ensures it currently never will appear. (Sorry about the egregious nested if statements. I wanted an explicit hide command for any of the possible reasons NOT to show the region/texture.)

Using Weakauras, of course.

You should be getting an error.
Usage: UnitAura("unit", [index][, "filter"])

I am getting an error but not sure what to do about it. Please forgive me for my lack of know how. I have looked at that url and not sure what Im doing wrong.

Probably better to use:
local defend = AuraUtil.FindAuraByName("Defensive Stance", "player")

A few months ago weakauras added an option for anchoring to a custom frame. I would use that instead of using the trigger to mess with the anchor.

Set Display > Position Settings > Anchored to to custom and put this in the code box

function()
    return C_NamePlate.GetNamePlateForUnit("target")
end

Then you can use the built in aura and cooldown triggers.

Thank you very much. That worked. There are two things, though, that seem a bit wonky with using the built-in anchoring approach:

  1. No matter what frame strata I place the aura in, all nameplates appear in front of these textures. That means with multiple mobs, I can’t see it. That problem didnt exist with the custom trigger approach.
  2. switching targets doesnt always switch the texture. The custom trigger always kept the textures on the currently selected target.
