Creating AddOns w/o BETA Access

[Capadillo]

I am looking at creating a UnitFrame addon for ESO when it comes out, and I would like some assistance from programmers (either in, or out of PTS testing) to make sure I am close to the mark.

local assocFrame = {
    "player" = {
        POWERTYPE_HEALTH  = "playerHealthBar",
        POWERTYPE_MAGICKA = "playerMagickaBar",
        POWERTYPE_STAMINA = "playerStaminaBar",
    },
    "target" = {
        POWERTYPE_HEALTH  = "targetHealthBar",
        POWERTYPE_MAGICKA = "targetMagickaBar",
        POWERTYPE_STAMINA = "targetStaminaBar",
    },
}
 
local barWidth, barHeight = 200, 20
 
local function eventUpdatePower(unit, powerType, powerCurrent, powerMax)
    local statusBar = assocFrame[unit][powerType]
    if not powerCurrent or not powerMax then
        powerCurrent, powerMax = GetUnitPower(unit, powerType)
    end
    statusBar:SetDimensions(( powerCurrent / powerMax ) * barWidth, barHeight)
end

I am reading through some existing addons, but actually getting info straight from you guys would be much better.

EDIT: I am assuming that "EVENT_POWER_UPDATE" will return all of the information for updating the individual powers as well, so we would only need to use "GetUnitPower" to force an update, or during login?

EDIT2: Updated the code...

EDIT3: Thank you for moving. I completely missed the dev forums. :3
