Creating castbar

[Layback_]

Hi again all,

First of all, I apologize as I feel like I'm spamming on this forum ...

I was trying to create a castbar and it was pretty easy to handle with.

Here's what I have done so far.

A.CreateCastbar = function(f, unit)
    local Castbar = CreateFrame("StatusBar", "$parentCastbar", f);
    Castbar:SetStatusBarTexture(POWER_BAR);
    Castbar:SetSize(348, 33);
    Castbar:SetPoint("CENTER", UIParent, "CENTER", 20, -350);
 
    Castbar.border = {};
    A.CreateEightBorders(Castbar, Castbar, "Border", BACKDROP, {0, 0, 0, 1});
 
    Castbar.bg = Castbar:CreateTexture(nil, "BACKGROUND");
    Castbar.bg:SetAllPoints(true);
    Castbar.bg:SetTexture(BACKDROP);
    Castbar.bg:SetVertexColor(0.20, 0.20, 0.20, 1);
 
    local Spark = Castbar:CreateTexture(nil, "OVERLAY");
    Spark:SetSize(20, 20);
    Spark:SetBlendMode("ADD");
 
    local Time = Castbar:CreateFontString(nil, "OVERLAY");
    Time:SetFont(VALUE_FONT, 15, "OUTLINE");
    Time:SetPoint("RIGHT", Castbar, "RIGHT", -5, 0);
 
    local Icon = Castbar:CreateTexture(nil, "OVERLAY");
    Icon:SetSize(33, 33);
    Icon:SetPoint("RIGHT", Castbar, "LEFT", -5, 0);
 
    Icon.border = {};
    A.CreateEightBorders(Icon, Castbar, "Border", BACKDROP, {0, 0, 0, 1});
 
    f.Castbar = Castbar;
    f.Castbar.bg = Castbar.bg;
    f.Castbar.Spark = Spark;
    f.Castbar.Time = Time;
    f.Castbar.Icon = Icon;
end

This is working fine, but I currently have one concern.

Since Castbar and Castbar.Icon are two different objects(?) (I know Icon is a child object, texture, of Castbar...), in order for me to center the entire thing, it looks like I'll have to manually move the castbar to the right by certain amount and that's why I moved Castbar frame by 20.

So, my question is that whether it is possible or not to move two things, Castbar and Castbar.Icon, as a group so that it maintain x-offset of Castbar to 0.

I hope you guys understand what I'm trying to say lel

You have already done this :

Icon:SetPoint("RIGHT", Castbar, "LEFT", -5, 0);

Your point is already relative to your castbar.

Moving the castbar will move the icon aswell.

Hi zork,

Yeah I know moving Castbar will also move Icon as well

Hm...... how should I explain this...

When Castbar is on its original point while the Icon is created, it would look something like this.



And currently, Castbar has an x-offset of 20 in order to center Castbar and Icon.



So, what I am hoping to achieve is...

1. Maintain x-offset of Castbar to 0 (like first image)

2. Center the Castbar and Icon (like second image)

3. Keep Icon to be anchored to Castbar (not Castbar anchored to Icon)

I guess it's like creating a parent frame or a helper frame that manages this..... maybe...................



Hope you understand what I am trying to say




EDIT: One extra question apart from the main one!

Does "PostUpdate~~~~", "PostCreate~~~~", "PreUpdate~~~~" and "PreCreate~~~~" functions exist as a placeholder(?) for developers to create themselves a variation on frames?

The post functions are hooks. We already had that discussion for PostUpdate on Health.
You can use the hooks on any of your castbars or you don't.

If you know the width of the icon, the offset between both objects and the width of the castbar you can just offset the point of the castbar via calculation.

Yeah, I definitely remember that we discussed about it few months ago as I have personally gone through your oUF_Doom over 50 times which I still could've not understand 100%, but I feel like I can get it now

You are right! I should re-visit my code and make some changes

Thank you for enlightening me!!
