Composer Overlay always starting

Hello all,

Disclaimer: very new to Corona…

I have a question regarding composer overlays. I’m kind of abusing the overlay function (I think) for a tutorial scene showing. So, I start a scene, and in the scene I have the following:

    if myLevel.showTutorial == true then
        composer.showOverlay( “showtutorial”, {isModal=true, effect=fromTop} )
    end
       
    createLives()
    createProgress()
    createGame()

This does work, but I don’t want the createLives and other functions to start… I want them to wait until the overlay is finished. Is this possible or should I try a different route?

Thanks,

Arne

Hi!

Try to define the time of the overlay transition inside the showOverlay function and then start a timer to run the functions at the bottom only at the end of the overlay.

Like in:

local overlayTime = 500 -- THIS IS TIME IN MILLISECONDS if myLevel.showTutorial == true then local options = { time = overlayTime, --ADDED TIME IN THE OPTIONS isModel = true, effect = fromTop } composer.showOverlay( "showtutorial", options ) -- PASSING THE OPTIONS TABLE CREATED BEFORE end -- DEFINING A FUNCTION THAT CALLS THE THREE FUNCTIONS THAT YOU NEED AFTER THE OVERLAY local actionAfterOverlay = function() createLives() createProgress() createGame() end -- CALLING A TIMER THAT CALLS THE FUNCTION "actionAfterOverlay" after 550ms timer.performWithDelay(overlayTime+50, actionAfertOverlay)

Refer to the API documentation for more info:

https://docs.coronalabs.com/api/library/composer/showOverlay.html (about what parameters can you pass at showOverlay function)

https://docs.coronalabs.com/api/library/timer/performWithDelay.html (about Timers, which you’ll use a lot in pretty dynamic projects)

Hope that helps ^^

Hi Rob,

Thanks for the feedback. Your code looks a lot better than mine :). I did have some code that was having problems (not sure exactly what), but everything is ok.

Thanks again,
