healthbar help/question

[nin]

hey ppl's

ive been playing around with a layout with opacity.. and what i want to achieve is too have the healthbar transparent but the background a solid color for better visual's when ppl loose health etc..

im very limited when it comes to coding and have never seen anyone do anything similar so i honestly have no clue how to code this in ouf or exactly what too look after.. i know it's possible in pitbull so it should be doable in ouf?

here's what my layout looks like..

You want a solid black background with a slightly transparent healthbar on top?

    local bg = self.Health:CreateTexture(nil, "BACKGROUND")
    bg:SetTexture(0,0,0,1)  --rgba
    bg:ClearAllPoints()
    bg:SetAllPoints(self.Health)
    self.Health.bg = bg

You may see the problem.

self.Health.bg is anchored to self.Health so if you add an alpha value to self.Health it gets applied to self.Health.bg aswell because its a "child" of self.Health

Solution

    local bg = self:CreateTexture(nil, "BACKGROUND")
    bg:SetTexture(0,0,0,1)  --rgba
    bg:ClearAllPoints()
    bg:SetAllPoints(self.Health)
    self.Health.bg = bg

The texture is now anchored to the self element and not to self.Health thus independent.

Best of luck.

my explanation skillz sucks!

what i want is too keep the opacity on the health bar (toplayer) but get the background more solid. what happens too me now when changing the background too a more solid color is that the opacity of the whole bar dissapears..

so i want too keep the healthbar transparent but the background solid when loosing health, that makes sense?

here's a edited screenie that i think explains it better..

thanks for the quick reply! ;>

Ah ok. This can only be done with a trick. The red bar from your loosing health must be your actual health bar, just with inverted value and from right to left.

The transparent stuff will be your background. So basically your healthbar fills from right to left when loosing health.

This requires that you create your own PostUpdateHealthFunc. Not possible with standard oUF imo.

ah okay.. i figured it would be tricky.. :P

thanks a lot for the info though!

You kinda have to use your own statusbar implementation if you want to do reverse statusbar filling with transparency.

WoW progromming states that the default statusbar object does not support right-to-left filling. So this can only be done by creating statusbars that aren't statusbars.

I've done this (kinda) in my layout "oUF Kritt".
I make them fill instead of deplete and go from right to left, simply by using a texture and math.
