New to creating oUF needs help

[ahhnam]

I am pretty new to programming so for the past week I was looking into other people's oUF files to try to get a basic understanding of what to do and come up with something that doesn't seem to work properly and I can't really figure out why and was just wondering if anyone can give me some pointers. Thank you.

-- Framework

local function Func(self, unit)
	self.colors = colors
	self.menu = menu
	
	self:RegisterForClicks('anyup')
	self:SetAttribute('*type2', 'menu')
	
	self:SetScript('OnEnter', UnitFrame_OnEnter)
	self:SetScript('OnLeave', UnitFrame_OnLeave)
	
	self:SetBackdrop(backdrop)
	self:SetBackdropColor(0, 0, 0)

-- Health Frame
	
	self.Health = CreateFrame('StatusBar', nil, self)
	self.Health:SetHeight(20)
	self.Health:SetWidth(200)
	self.Health:SetPoint("TOPLEFT")
	self.Health:SetPoint("TOPRIGHT")
	self.Health:SetStatusBarTexture(minimalist)
	self.Health.frequentUpdates = true
	self.Health.colorSmooth = true
	self.Health.colorClass = true
	
	self.Health.bg = self.Health:CreateTexture(nil, 'BORDER')
	self.Health.bg:SetAllPoints(self.Health)
	self.Health.bg:SetTexture(0.3, 0.3, 0.3)
--

-- Power Frame

	self.Power = CreateFrame('StatusBar', nil, self)
	self.Power:SetHeight(3)
	self.Power:SetWidth(200)
	self.Power:SetPoint("TOPLEFT", self.Health, "BOTTOMLEFT", 0, -3)
	self.Power:SetPoint("TOPRIGHT", self.Health, "BOTTOMRIGHT", 0, -3)
	self.Power.colorSmooth = true
	self.Power.frequentUpdates = true
	self.Power.colorPower = true
--

end

oUF:RegisterStyle('3xp', Func)
oUF:SetActiveStyle('3xp')

oUF:Spawn('player'):SetPoint('CENTER', UIParent, -220, -250)

Yep that's it, I tried to see if I can get the basic working before going further and so far it's still failing.

You really should not start from scratch if you are new to oUF, imho. I would crab one of the existing layouts and modify them to your need or at least look at oUF_Classic and/or oUF_Lilly which are so to say "official" layouts for reference, by haste.

Besides of that your layout is TO basic, you need to add a little more to actually spawn some frames.

Is that the entire code or are you posting just a part of it?
What errors are you getting?

[Dawn]

It's pretty much possible that this code doesn't produce much or any errors. At least it's shouldn't show anything in game.

[ahhnam]

I see, yea that was sort of the problem lol nothing would show up, I thought that maybe at least it would show my own hp and power bars but I guess not. Anyway thanks for your help, I'll add more to it first before posting again, this is sort of like a side project thing for me so I understand lua a little better. =)

[haste]

your frame is missing initial height/width.

[Beladona]

for starters, you need to set the size of the frame itself, either by anchoring two opposing points, or doing a SetWidth and SetHeight on it. I would recommend the latter:

self:SetWidth(200);
self:SetHeight(26);

next, you are setting the width and height of the health and power bars. But then you are also setting the TOPLEFT and TOPRIGHT points. Doing this means you don't need SetWidth. So you may as well remove that, and just keep the SetHeight for each bar. They will already be a width of 200, since that is the width of your frame and you are anchoring the TOPLEFT and TOPRIGHT to the TOPLEFT and TOPRIGHT of your frame anyway.

Next, nowhere do I see you define colors, menu, backdrop, or minimalist. One assumes you aren't showing us all of your code, but I don't like to assume, so I would make sure you have those defined somewhere in your file.

[haste]

Using SetWidth / SetHeight isn't recommended. You'll get some taint warnings doing that on the party frames.

First off, thank you for all your replies and I took the advice and took Classic as a guide and edited a lot of the codes from inside and looks something like this. It's really messy right now and I still don't have a good enough understanding to what I am doing but it's a start.

As for questions,
1. I'm trying to create cast bars using ouf_p3lim as a guideline and so far what I did with it doesn't seem to function at all and I can't seem to figure out what's going on and what I am missing from it.

Sorry for the noob questions and thanks in advance.

Take the "self.Castbar = cb" and put it at the end of the code where you define cb. Otherwise, when it's assigned, cb is nil and so is your castbar.
