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

Orhun

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.
