Blinking widget

[Setras]

Hi guys. I need a simple and nice way to make a widget blink like 10 times and stop blinking.

Problem is... It's possible that there will be dozens of such widgets and i don't want to store a global var-table containing info about "how much times did certain widget blink"... And i want them to blink like... repeatedly...

Let's share ideas about making it effective and fast?

Aloha!

You can make yourself a little helper library, which basically will launch given sequence of effects, say

Code:

local sequence = {}

for k = 1, 10 do

  table.insert( sequence, { 0.5, 1, 1000 + 50 * k, EA_SYMMETRIC_FLASH } )

end

fxlib.PlayFadeEffectSequence( widget, sequence )

Each cell in this sequence is a set of arguments for AO Lua API widget method "PlayFadeEffect". It can be used like

Code:

local cell = sequence [ i ] 

widget:PlayFadeEffect( unpack( cell ) )

Library itself can register on demand a single handler for API event "EVENT_EFFECT_FINISHED", which will identify current playing sequence and launch effect for next sequence cell from library's internal hash. Something like

Code:

handlers [ "EVENT_EFFECT_FINISHED" ]  = function( event )

  local widget = event.wtOwner

  local instanceID = widget:GetInstanceId()

  local sequence = hash [ instanceID ] 

  if sequence then

    local i = sequence.i or 1

    local cell = sequence [ i ] 

    sequence.i = i + 1

    if cell then

      widget:PlayFadeEffect( unpack( cell ) )

    else

      widget:FinishFadeEffect()

      hash  [ instanceID ]  = nil

    end

end

You can expand this approach on all types of widget effects in AO, and as outcome you'll get most effective and powerful AO user-made library ever existed.

Cheers! =)
