I already said it's on the roadmap somewhere behind the release of my UI and definitely far behind passing my exams till mid march. If you feel a great urge for having nifty boss frames right now go ahead as I really don't have time for all of this right now.

That's like taking a sledgehammer to crack a nut. Just add this to custom_Modifications.lua:


Replace R, G, B, A with values (0-1.0) for red, green and blue portions and opacity.

That on the other hand is really due to the loading order. I guess I'll find a way to make that global next patch. Right now you could do something like self.Buffs.PostUpdateIcon = oUF_player.Buffs.PostUpdateIcon.

That is, fortunately for you, not true. Custom modifications are applied at the very end of the loading process. Think of your custom mod as being a second version of the function which is called after every time the original function is called.

This means you can not access local variables of the specific function that you hook into. What you can do however is access the parameter list and in the case of sharedStyle() the parameter self, which happens to be the frame that you want to modify.

What you do is search for the element which is "published" through self like self.power, self.TotemBar and do whatever you want to do with it and believe me this gives you the possibility to change every element.

So speaking of the holy power element the following example which changes the foreground color of the first holy power icon works perfectly fine:


The example of the holy power element that you mentioned is actually really good to clarify this even more. The original code goes like this:


So a holy power icon consists of a background texture (bg[i].tex), and the fill texture (self.HolyPower[i]), both of them hosted inside the frame bg[i]. As already said you can easily access self.HolyPower over the self parameter inside a custom mod hooked into sharedStyle(). You couldn't access bg[i] since it is local (local bg = {}). But in this case you're in luck: just change it via self.HolyPower[i]:GetParent() if you need to as self.HolyPower[i] is a child element of bg[i] (self.HolyPower[i] = bg[i]:CreateTexture(nil, "OVERLAY"))

In conclusion the following example changes the color of the holy power icon background texture:


Hooking into other functions is bit more straightforward. If you want to replace the logic behind the aura magnification to pick up your example you just hook into OnEnterAura(...) and create your own logic - simple as that. A good start would be to copy-paste the code into your custom mod and change it the way you want.

I hope that illustrated the system enough to point you in the right direction because I honestly lost track of your conversation and I frankly don't want to write the mods for you myself.
