lua - Corona going to previous scene results in black screen -

-

i've got problem delaying game milestone, in scene1 click menu button takes me menu when user wants play again click play button , should go previous scene when goes black screen. here code, main menu button in scene 1:

function scene:enterscene(event)   local group = self.view   function menubutton:touch( event ) if event.phase == "began"     storyboard.gotoscene( "menu", "slideright", 750 )     audio.play(click)     display.getcurrentstage():setfocus( event.target )     event.target.isfocus = true elseif event.target.isfocus     if event.phase == "moved"         print( "user has moved finger off button." )     elseif event.phase == "ended"         print( "user has switched main menu" )         display.getcurrentstage():setfocus( nil )         event.target.isfocus = false     end end return true

end

here play button on main menu:

function scene:enterscene(event) local group = self.view   local function onscenetouch( event )     if event.phase == "ended"        audio.play(click)        local previousscene = storyboard.getprevious()        if previousscene == nil        storyboard.gotoscene( "scene1", "slideleft", 750 ) else        storyboard.gotoscene(previousscene)         return true     end  end end

any ideas? getting no errors in simulator output.

edit: line of code stopped blank screen when placed on menu, images show up, background image button images etc nothing else.

local prior_scene = storyboard.getprevious() storyboard.purgescene( prior_scene )

try use tap listener instead of touch listener. don't see entire code think there problem.

main menu button in scene 1:

function scene:enterscene(event)      local group = self.view      local function onmenubuttontap( event )         audio.play(click)         storyboard.gotoscene( "menu", "slideright", 750 )         return true     end end

play button on main menu scene:

function scene:enterscene(event)     local group = self.view       local function onplaytap( event )         audio.play(click)         local previousscene = storyboard.getprevious()         if previousscene == nil             storyboard.gotoscene( "scene1", "slideleft", 750 )         else             storyboard.gotoscene(previousscene)         end         return true     end end

------------------------------------------------------------
new code:
------------------------------------------------------------
change in scene1.lua

function scene:exitscene(event)      local group = self.view     storyboard.destroyscene( "scene1" )  end

with this

function scene:exitscene(event)       local group = self.view  end

in menu.lua add this:

function scene:createscene( event )     local group = self.view      storyboard.purgescene( "scene1" ) end  scene:addeventlistener( "createscene", scene )
