    How to slow down the speed of the button to appear on stage.

    Hi everybody,
    I'm am trying to develop a simple soundboard app.
    In my app splash screen i created a animated character sprite and a simple start button sprite.

    My problem is, i don't know how to slow down the speed of the start button to appear on stage.
    I want to set it visible after my animated character sprite appears on stage.For example 2-3 second later.
    But my button sprite appearing on the stage first.
    Which function code controls this.

    My button code is the following."Baslat" is my button name.

    local up = Bitmap.new(Texture.new("up.png"))
    local down = Bitmap.new(Texture.new("down.png"))
    local Baslat = Button.new(up, down)
    Baslat:setPosition(100, 450)
    stage:addChild(Baslat)

    Help please.

      Hi @Orhun, try this
      http://docs.giderosmobile.com/reference/gideros/Timer/delayedCall
      Timer.delayedCall(1000 , function()
local up = Bitmap.new(Texture.new("up.png"))
local down = Bitmap.new(Texture.new("down.png"))
local Baslat = Button.new(up, down)
Baslat:setPosition(100, 450)
stage:addChild(Baslat)
end)

      The best way to achieve this using "ADDED_TO_STAGE" event for your character sprite. When event fires then you can add your button to stage.
      characterSprite:addEventListener(Event.ADDED_TO_STAGE ,function()
      -- add your button here
end,self)

      Thanks for the replies.
      Mertocan, i tried your code but it didn't worked. is the following code correct?my character sprite name is "bb8".I couldn't find the error
      bb8:addEventListener(Event.ADDED_TO_STAGE ,function()
      local up = Bitmap.new(Texture.new("up.png"))
local down = Bitmap.new(Texture.new("down.png"))
local Baslat = Button.new(up, down)
Baslat:setPosition(100, 450)
stage:addChild(Baslat)
end,self)
      By the way i am a complete newbie in programming except graphic design:)
      So my questions can be very simple.

      Which error are you getting?

      I think you are trying to do it on stage. Therefore, your self is nil.

      Try this one. It should work.
      bb8:addEventListener(Event.ADDED_TO_STAGE ,function()
      local up = Bitmap.new(Texture.new("up.png"))
      local down = Bitmap.new(Texture.new("down.png"))
      local Baslat = Button.new(up, down)
      Baslat:setPosition(100, 450)
      stage:addChild(Baslat)
end,bb8)
      BTW, to make it clear, you should move event function to outside of scope in order to remove event when it is completed. So,
       
function addButtonToStage()
 
      local up = Bitmap.new(Texture.new("up.png"))
      local down = Bitmap.new(Texture.new("down.png"))
      local Baslat = Button.new(up, down)
      Baslat:setPosition(100, 450)
      stage:addChild(Baslat)
 
      bb8:removeEventListener(Event.ADDED_TO_STAGE ,addButtonToStage(),bb8)
end
 
 
bb8:addEventListener(Event.ADDED_TO_STAGE ,addButtonToStage(),bb8)

      is better implementation.
