Where to start? - Boilerplate Help

[Jagwah]

Hi all,

I'll preface this by admitting that I'm very new to all of this; outside of editing the lua of existing addons, I don't have much experience and I'm pretty much learning as I go.

My first question is about documentation--I've not found much other than the in-line documentation in the oUF code and the boilerplate. Does anything along these lines exist?

I've had a go at spawning a player health bar; it's not throwing up any errors but isn't displaying either. I feel like I might have missed something really obvious, but after an hour of checking various bits I just can't work it out. Can anyone point me in the right direction?

EDIT: Having tested, my party frames have disappeared too.

Thanks in advance! I have oUF where it should be (unembedded) and have a single TOC entry pointing to a single LUA file (which I've pasted in its entirety below):

local _, ns = ...
 
local UnitSpecific = {
  player = function(self) -- Player Specific Code
  end,
 
  party = function(self)  -- Party Specific Code
  end,
}
 
 
local Shared = function(self, unit) -- Shared Unit Code
 
  local Health = CreateFrame('StatusBar', nil, self) -- Create Health Bar
  Health:SetSize(300, 20)
  Health:SetPoint('TOPLEFT', UIParent, "TOPRIGHT", 0, 0)
  Health:SetPoint('BOTTOMLEFT', UIParent, "BOTTOMRIGHT", 0, 0)
 
  local HealthBG = Health:CreateTexture(nil, 'BACKGROUND') -- Create Health Background
  HealthBG:SetAllPoints(Health)
  HealthBG:SetTexture(1, 1, 1, .5)
 
  Health.colorClass = true
  Health.colorReaction = true
 
  HealthBG.multiplier = .5
 
  Health.bg = HealthBG
  self.Health = Health
 
 
  if(UnitSpecific[unit]) then
      return UnitSpecific[unit](self)
    end
  end
 
 
oUF:RegisterStyle("jUI", Shared) --Register Style with oUF
oUF:Factory(function(self)
 
  self:SetActiveStyle("jUI")
  self:Spawn("player"):SetPoint('CENTER')
 
  local party = self:SpawnHeader(nil, nil, 'raid,party,solo',
    'showParty', true,
    'showPlayer', true,
    'yOffset', -20
    )
  party:SetPoint("TOPLEFT", 30, -30)
end)
