Unable to change certain nameplate properties

[daylesan]

A nameplate frame has 11 regions and 2 child frames (statusbars) associated with it.

I have some code that successfully changes the textures, but can't seem to change the size or anchor points of the regions and child frames.

Is this because the game automatically re-sets the size and anchor point every frame or some non-obvious other thing?

imho the game sets the anchor points only once.

I just did some quick and dirty tests, and it works as expected. If I do

region:ClearAllPoints()
region:SetPoint("TOPLEFT", parentframe, "TOPLEFT")

with the nametext region. The default anchor (BOTTOMLEFT) is cleared and the new anchor is set and persists - even if the nameplate is temp. hidden.
Didn't test the other regions, but I would be surprised if this is not the same with these.

[Edit]
So ... this must be a flaw in you code. Please post you code.

Quite a few nameplate elements get re-anchored behind the scenes when nameplates are shown. Off the top of my head, level text, the mouseover highlight texture, and name text all get re-anchored OnShow. It's a bit of a black box though, so you'll probably have to experiment with any elements that seem to reset.

One thing to look out for is that some elements don't get reset until the OnUpdate handler that fires immediately after a plate's OnShow. Level texts and castbar uninterruptibility textures are like this, though there may be more that I haven't noticed.

Another thing to be aware of is your "bloattest" cvar. I know for sure it affects if and when parts of nameplate castbars get reset, but it might affect other elements too. I can't remember if it resets elements more when on or off, though.

Name text definitely isn't re-anchored - at least not at OnShow.

Hooking the OnUpdate script is the way to go then?

In my mod, I set the OnUpdate handler during OnShow. My OnUpdate handler then unregisters itself so that it only runs once per OnShow.

There are currently some changes to nameplates on the PTR. First off, they haven't got 11 regions anymore, they have 8. Some of the regions has been moved into the castbar object, which is the 2nd child of the nameplate.

Secondly, they have names now. NamePlate1, NamePlate2, etc etc. There can be hundreds.

On live realms (4.0.6), I use this little code to get the various regions of the nameplates and their castbars (where f represents the nameplate frame):

f.health, f.cast = f:GetChildren()
f.threat, f.border, f.castborder, f.shield, f.casticon, f.highlight, f.name, f.level, f.bossicon, f.raidicon, f.dragon = f:GetRegions()

On the PTR, I use this:

f.health, f.cast = f:GetChildren()
 
-- patch 4.1
if f:GetName() and strfind(f:GetName(), "NamePlate") then
    -- not 100% sure about the f.castbartexture-thing here. I _think_ it refers to the statusbar texture of the castbar. At least that's what disappeared when I hid it
    f.castbartexture, f.castborder, f.shield, f.casticon = f.cast:GetRegions()
    f.threat, f.border, f.highlight, f.name, f.level, f.bossicon, f.raidicon, f.dragon = f:GetRegions()
else
    f.threat, f.border, f.castborder, f.shield, f.casticon, f.highlight, f.name, f.level, f.bossicon, f.raidicon, f.dragon = f:GetRegions()
end

Hooking up to every NamePlate's OnUpdate handler is a terrible way to go, as this would fire off the function for every nameplate, on every Update of the WorldFrame.

I use the nameplate's OnShow and OnHide, as well as the castbars' OnShow, OnSizeChanged and OnValueChanged.

You can dig through it yourself in the modules\nameplates\ folder:
