Hi, there! I have only began to code. 1st problem - why doesn’t “fade” work??
Don’t with this code
local composer = require (“composer”)
local options = {
effect = “fade”,
time = 800,
}
composer.gotoScene(“start”, options)
and don’t with this
local composer = require (“composer”)
composer.gotoScene(“start”, “fade”, 400)
Just nothing fading effect happens when new scene is openning.
I just tested it in an app I’m building and it works as expected:
Here is my entire main.lua:
local composer = require( "composer" ) -- Hide the status bar display.setStatusBar( display.HiddenStatusBar ) -- Seed the random number generator math.randomseed( os.time() ) display.setDefault( "background", 0 ) local options = { effect = "fade", time = 800, } -- this will eventually go to the menu scene. composer.gotoScene( "game" , options )
Now what you describe is symptomatic of either a) not putting your display objects into the scene’s view group (i.e. sceneGroup:insert(background) or b ) you are creating your objects in scene:show() instead of scene:create().

Rob, thanx! Got some fix and it start working. So we should put any graphics to sceneGroup for working FADE?? How does it connect with each other?? In advance thanx for tolerance =)
Composer is a scene manager. If you want Composer to manage your scene, those display objects have to be added to the scene’s “view”.
Under the hood, the view is nothing more than a display.newGroup(). When you create the scene using:
local scene = composer.newScene()
It creates a new group named “view” and makes it part of the scene. i.e.:
scene.view
If you use local functions:
local function doSomething() local sceneGroup = scene.view ... end
If you use object functions:
function scene:doSomethingElse() local sceneGroup = self.view ... end
In the Composer event functions (create, show, hide, destroy), they are all of the “object function” model. With the colon operator (:), it passes an object named self to the function. So:
for object functions: sceneGroup = self.view = scene.view.
for local functions: sceneGroup = scene.view (no self available)
Anything you want to fade in and out must be in scene.view regardless of how you get it there:
sceneGroup:insert( object )
scene.view:insert( object ) – does the same thing as above.
I’m not sure what you mean by “How does it connect with each other??”

Just right that u wrote. I meant how is it connected(or linked)? Scene and Fade. I understood, thanx!
